Answer:

Explanation:

i dont know what im suppose to explain

Answer:

I'd say it's B

Sorry if I get you wrong-

Answer:

In Newton’s first law, an object at rest remains at rest until an external force isapplied. When I play soccer, the soccer ball will be at rest on the field (the initial condition) andremain in that spot on the field until I kick it (my muscles applying an external force to the ball).According to Newton’s second law, force = mass x acceleration (F=ma). When I kick the resting soccer ball, which has a given mass, it will accelerate in the direction that I kick it. From the equation, acceleration = force divided by mass. Therefore, since the mass of the soccer ball is fixed, the stronger my leg is and the more force I can apply to the ball, the faster it willaccelerate.According to Newton’s first law, an object in motion remains in motion until an external force isapplied. After I kick the soccer ball, it will continue in motion in the direction that I kicked it,but its acceleration will gradually slow down due to the external forces of friction from the airand the surface of the field. According to Newton’s third law, for every action there is an equal and opposite reaction.When I kick the soccer ball forward, if I also kick it in an upward direction, such as a thirty-degree angle from the field, it will come down at an angle when it strikes the field. When theball lands and strikes the field, there will be an equal and opposite reaction whereby instead oftraveling downward it will bounce of the surface of the field and will then be travelling upward.

Newton's Law of Cooling is described by the first-order linear differential equation dt/dT = k(T - Ts), where T(t) is the temperature of the object at time t, Ts is the surrounding environmental temperature, and k is the constant of proportionality.

The temperature of an object, governed by Newton's Law of Cooling

(i) To find the temperature of the object as a function of time, we first solve the differential equation dt/dT = k(T - Ts). This is a separable differential equation, and the solution can be obtained by rearranging and integrating:

dt/dT = k(T - Ts)

dt = k(T - Ts) dT

∫ dt = ∫ k(T - Ts) dT

t = k * ∫ (T - Ts) dT

t = k * (T^2/2 - Ts*T) + C

Now, we apply the initial condition T(0) = T0. At t=0, the temperature of the object is T0:

T(0) = T0

k * (\(T0^2\)/2 - Ts*T0) + C = T0

C = T0 - k * (\(T0^2\)/2 - Ts*T0)

C = T0 - k * (\(T0^2\)- 2 * Ts * T0) / 2

C = T0 - k * (\(T0^2\) - 2 * Ts * T0) / 2

So, the equation becomes:

t = k * (\(T^2\)/2 - Ts*T) + (T0 - k * (\(T0^2\)- 2 * Ts * T0) / 2)

(ii) Now, we can find the temperature of the object after 5 minutes (t = 5 minutes). We'll use the initial condition T(0) = T0 and the formula obtained in part (i):

t = 5 minutes = 5/60 hours = 1/12 hours

T(t) = Ts + (T0 - Ts) * exp(-kt)

T(1/12) = Ts + (T0 - Ts) * exp(-k * (1/12))

This equation gives us the temperature of the object after 5 minutes, considering the given initial temperature T0 and the surrounding environmental temperature Ts.

The positive feedbacks without uncertainty are water vapor feedback. The feedbacks that affect the terrestrial radiation budget are lapse rate feedback, ice-albedo feedback, water vapor feedback, and cloud feedback.

Among the feedbacks listed, the ones that are definitely positive (without uncertainty) are: 1. Water vapor feedback: An increase in temperature leads to an increase in atmospheric water vapor content, which amplifies the greenhouse effect and further enhances warming. This feedback is positive. The feedbacks that affect the terrestrial radiation budget (the balance of incoming and outgoing radiation at the Earth's surface) are: 1. Lapse rate feedback: This feedback is related to the vertical temperature profile of the atmosphere. If the lapse rate (the rate at which temperature changes with altitude) decreases with warming, it can amplify the warming or cooling effects. It affects the radiation budget indirectly by influencing the atmospheric temperature structure. 2. Ice-albedo feedback: When temperatures rise, ice and snow cover decrease, exposing darker surfaces (such as land or ocean) that absorb more solar radiation. This leads to further warming, creating a positive feedback loop that affects the radiation budget. 3. Water vapor feedback: As mentioned earlier, an increase in temperature leads to increased atmospheric water vapor content. Water vapor is a potent greenhouse gas that affects the radiation budget by trapping outgoing longwave radiation and amplifying the greenhouse effect.b4. Cloud feedback: Changes in temperature and atmospheric moisture content can affect cloud formation and properties. Clouds can either trap heat (positive feedback) or reflect sunlight back to space (negative feedback), depending on their type, altitude, and coverage. The net effect of cloud feedback on the terrestrial radiation budget depends on the specific cloud changes in response to warming.

Work done by the applied force on car can be calculated using the formula W = F⃗ ⋅ d⃗, where F⃗ is the force vector and d⃗ is the displacement vector. The force vector is F⃗ = 68.0 N i + 36.0 N j, and the displacement vector is d⃗ = 41.0 m at an angle of 240.0° counterclockwise from the x-axis.

To find the work done by the force on the car, we need to calculate the dot product of the force vector and the displacement vector. The dot product can be obtained by multiplying the magnitudes of the vectors with the cosine of the angle between them.

First, let's find the magnitudes of the force vector and the displacement vector. The magnitude of the force vector F⃗ is given by |F⃗ | = √((68.0 N)² + (36.0 N)²) = 76.16 N. The magnitude of the displacement vector d⃗ is |d⃗ | = 41.0 m.

Next, we calculate the angle between the force vector and the displacement vector. The angle is given as 240.0° counterclockwise from the x-axis. Since the x-axis is the reference axis, the angle between the force vector and the displacement vector is 180.0° - 240.0° = -60.0°.

Now, we can calculate the work done using the formula W = |F⃗ | |d⃗ | cosθ, where θ is the angle between the force and displacement vectors. Therefore, W = (76.16 N) * (41.0 m) * cos(-60.0°) = -1573.4 J.

The mechanical advantage of a tool, mechanical device, or machine system is a measure of force amplification. To achieve the desired amplification in output force, the device trades off input forces against movement. The law of the lever serves as a model for this.

It is the amount of force increased by using a tool or machine. It is equal to the tool or machine's force divided by the applied effort. A mechanical advantage is a type of calculation that calculates the amplified force exerted by a mechanical system. It calculates the ratio of the force applied to the load to the force required to overcome the given force. Because the two ratio quantities are the force, it is a unitless expression.

The position of a probe on the electrodes does not affect the measurement of the potential difference because of the nature of electricity.

Electricity is conducted through a conductor, such as the electrodes, by the movement of electrons. When a potential difference exists between two points, the electrons move from the negative side to the positive side in an effort to equalize the charge. The exact position of the probe on the electrodes does not matter because the electrons are already moving through the conductor. The electrons will flow through the electrodes regardless of where the probe is placed. As long as the electrodes are made of a conductive material, the potential difference between the two points will remain the same.

The slit separation that will produce first-order maxima at angles of ±35 degrees from the incident direction is approximately 1.11 micrometers.

To determine the slit separation that will produce first-order maxima at angles of ±35 degrees from the incident direction, we can use the equation for the location of the maxima in a double-slit interference pattern:

d * sin(θ) = m * λ

where d is the slit separation, θ is the angle from the incident direction, m is the order of the maxima, and λ is the wavelength of the laser light.

In this case, we want to find the slit separation (d) that produces first-order maxima at angles of ±35 degrees (θ = ±35 degrees) and the wavelength (λ) is given as 680 nm.

Let's calculate the slit separation for the positive angle (+35 degrees):

d * sin(35 degrees) = 1 * 680 nm

Converting the angle to radians and the wavelength to meters:

d * sin(0.6109 radians) = 1 * 680e-9 m

Simplifying the equation, we have:

d = (680e-9 m) / sin(0.6109 radians)

Calculating this expression, we find:

d ≈ 1.11e-6 m

To find the volume of the solid, we can use the triple integral. Since the solid is bounded by the planes z = x, y = x, x + y = 9, and z = 0, we can write the integral as:

V = ∭(D) dV = ∭(D) dx dy dz

where D is the region bounded by the given planes.

To set up the triple integral, we need to determine the bounds for the variables x, y, and z. Since the solid is bounded by the planes z = x, x + y = 9, and y = x, we can express z in terms of x and y. We have:

z = x

Since x + y = 9, we can also express y in terms of x:

y = 9 - x

Substituting this expression for y into the equation for z, we get:

z = x = x

Therefore, the bounds for x are 0 ≤ x ≤ 9/2. The bounds for y are 0 ≤ y ≤ 9 - x, and the bounds for z are 0 ≤ z ≤ x.

Using these bounds, we can set up the triple integral as follows:

V = ∭(D) dx dy dz = ∫x=0 to x=9/2 ∫y=0 to y=9-x ∫z=0 to z=x 1 dz dy dx

Evaluating this integral, we find that the volume of the solid is:

Earth is accelerated around the sun

The main cause of the spreading movement of the ocean crust is the new magma forming at ocean ridges, which pushes the oceanic plates apart. The other options listed do not contribute equally or directly to the spreading movement.

The spreading movement of the ocean crust is primarily driven by the formation of new magma at ocean ridges. As the mantle material beneath the Earth's surface rises and melts, it creates new magma. This molten material then pushes its way upward and fills the gap between the separating oceanic plates. As the new magma solidifies, it forms a new crust, expanding the ocean floor and causing the plates to move apart.

The other options listed do not directly contribute to the spreading movement of the ocean crust. Increasing temperatures at the top of the asthenosphere, the greater water content in subducted oceanic crust, decreasing pressure as the overlying crust thins, and higher viscosity as the silica content increases may have their own geological implications, but they are not the main causes of the spreading movement observed at ocean ridges.

The rotational speed of the motor 3 in rpm. b. 92

The figure shows a hydraulic circuit that uses three chain conveyors. The torque that drives the motors is T: =1500 N.m. T2 =700 Nm and, T3 = 300Nm.The volumetric flow rate produced by the pump is 6.3 liters per minute. The displacement volume of the motors is V01 =1000 cm3/rev. V02 =1000 cm3/rev and, V09 =500 cm3/rex.

The motors have a volumetric efficiency of 0.9 and an overall efficiency of 0.85. The leakage of hydraulic motors 1 and 3 is internal completely, while the leakage of hydraulic motor 2 is external completely.The orifice of the flow control valve has a diameter of 0.5 mm. The capacity coefficient of the needle valve is 0.7.

The pressure losses through the pipes are ignored. The volumetric flow rate through the needle valve is Q = C × A2 × ΔP / ρ where C is the capacity coefficient, A is the area of the orifice, ΔP is the pressure difference through the needle valve, and ρ is the density of the fluid. The density of the oil used in the hydraulic system is 860 kg/m3. We need to determine the rotational speed of motor 3 in rpm.

So,Let’s first determine the volumetric flow rate required by hydraulic motor 3. Using the expression of volumetric flow rate through the needle valve, we have Q = C × A2 × ΔP / ρ… (i)We are given that the capacity coefficient of the needle valve is 0.7. Its orifice diameter is 0.5 mm.

Hence, the area of the orifice is given byA2 = π d2 / 4where d is the diameter of the orifice. So, A2 = π × (0.5 mm)2 / 4 = 0.196 mm2 = 1.96 × 10-7 m2Using equation (i), we haveQ = C × A2 × ΔP / ρNow, we will calculate ΔP. To do this, we need to determine the flow rates Q1, Q2, and Q3.Let Q’ be the total volumetric flow rate through the system.

Since the overall efficiency of the system is given as 0.85, we haveQ’ = 0.85 × 6.3 l/min = 5.355 l/min = 5.355 × 10-3 m3/minWe know that the volume of fluid passing through the hydraulic motors is equal to their displacement volume multiplied by the number of revolutions per unit time.So, we haveQ1 = V01 × n1 … (ii)Q2 = V02 × n2 … (iii)Q3 = V03 × n3 … (iv)where V01, V02, and V03 are the displacement volumes of hydraulic motors 1, 2, and 3, respectively.

We are given that V01 = V02 = 1000 cm3/rev and V03 = 500 cm3/rev, which gives V01 = V02 = 1 × 10-6 m3/rev and V03 = 0.5 × 10-6 m3/rev.Substituting equations (ii), (iii), and (iv) in equation (i), we haveQ = C × A2 × (Q1 + Q2 - Q3) / ρSolving for Q3, we getQ3 = (Q1 + Q2 - Q) / C × A2 × ρPutting the given values in the above expression, we haveQ1 = V01 × n1 = (1 × 10-6 m3/rev) × n1Q2 = V02 × n2 = (1 × 10-6 m3/rev) × n2Q3 = V03 × n3 = (0.5 × 10-6 m3/rev) × n3Q = 5.355 × 10-3 m3/min = 5.355 × 10-3 / 60 m3/s = 8.925 × 10-5 m3/sA2 = 1.96 × 10-7 m2C = 0.7ρ = 860 kg/m3

Substituting the above values, we get8.925 × 10-5 = (1 × 10-6 × n1 + 1 × 10-6 × n2 - 0.5 × 10-6 × n3) / (0.7 × 1.96 × 10-7 × 860)Solving for n3, we have n3 = 91.6 rpmSo, the correct option is b. 92.

The Earth's atmosphere introduces turbulence that causes images captured by ground-based telescopes to be blurry and less detailed. Adaptive optics technology addresses this issue by actively measuring and correcting for the atmospheric distortions in real-time.

It uses deformable mirrors and wavefront sensors to analyze the distortions and make precise adjustments to the telescope's optics.

By continuously adapting to the atmospheric conditions, adaptive optics can compensate for much of the blurring effect, resulting in images that approach the clarity and resolution achieved by space-based telescopes.
