Therefore the value of F is 0.08 N.

Answer:

94600kgm/s

Explanation:

Linear momentum of a body can be calculated using the formula;

P = mv

Where;

P = linear momentum (Kgm/s)

m = mass of body (kg)

v = speed of the moving body (m/s)

According to the provided information in the question, m = 110kg, v = 860m/s

P = 110 × 860

P = 94600kgm/s

The change in momentum of a dynamic cart acted upon by the force of a spring is related to the impulse.Impulse is equal to the change in momentum of an object. The force that acts on an object over a given time period determines the impulse. It is the product of force and time.

Impulse, in fact, is also equal to the total momentum of the object before the force is applied. Impulse is a vector quantity with the same direction as the force, as well as the momentum.

The impulse delivered to the cart by the spring will be equal and opposite to the impulse exerted by the cart on the spring, according to Newton's third law of motion.

As a result, the change in momentum of the dynamic cart due to the force of a spring is related to the impulse.

When thrown from the balloon, the sandbag has a constant horizontal/forward velocity. As the text puts it, "the sandbag continues forward as if it had not been dropped." What this means is that the sandbag has no acceleration in the horizontal plane of motion, so it moves in this direction at a constant speed. So for any time \(t\), the horizontal velocity is given by

\(v_x(t) = 12\dfrac{\rm m}{\rm s}\)

In the vertical plane of motion, the sandbag has no vertical velocity until it's released and allowed to fall. As it's falling, however, the sandbag is being pulled down by gravity and is accelerating with magnitude \(g=9.8\frac{\rm m}{\mathrm s^2}\), so its vertical/downward velocity at time \(t\) is given by

\(v_y(t) = -gt\)

So, after 3 seconds have passed, the sandbag has horizontal velocity \(v_x = 12\frac{\rm m}{\rm s}\) and vertical velocity \(v_y = -g(3\,\mathrm s) = -29.4\frac{\rm m}{\rm s}\). If the question is specifically asking about speed you would just ignore the negative signs.

Explanation:

Right on ED2021, goodluck!

(Target M1) You have detected a previously-unknown planet orbiting the sun. You measure its mass to be 10 x 1021 kg and it is traveling in a circular orbit at 7 km/s. The distance of the unknown planet from the Sun is approximately 4.756 x 10^11 meters.

To determine the distance of the unknown planet from the Sun, we can use the principles of circular motion and gravitational force.

The centripetal force required to keep the planet in a circular orbit is provided by the gravitational force between the planet and the Sun. The gravitational force can be calculated using Newton's law of universal gravitation:

F = G * (m1 * m2) / r^2

where F is the gravitational force, G is the gravitational constant (6.67430 x 10^-11 m^3/kg/s^2), m1 and m2 are the masses of the two objects (in this case, the mass of the planet and the mass of the Sun), and r is the distance between the two objects.

In a circular orbit, the centripetal force is given by:

F = (m * v^2) / r

where m is the mass of the planet and v is the velocity of the planet in its orbit.

Setting the gravitational force equal to the centripetal force, we can solve for the distance r:

G * (m1 * m2) / r^2 = (m * v^2) / r

Rearranging the equation, we get:

r = (G * m1 * m2) / (m * v^2)

Substituting the given values:

m1 = mass of the Sun = 1.989 x 10^30 kg

m = mass of the planet = 10 x 10^21 kg

v = velocity of the planet = 7 km/s = 7000 m/s

G = gravitational constant = 6.67430 x 10^-11 m^3/kg/s^2

r = (6.67430 x 10^-11 * 1.989 x 10^30 * 10 x 10^21) / (10 x 10^21 * 7000^2)

Calculating the expression:

r ≈ 4.756 x 10^11 meters

Therefore, the distance of the unknown planet from the Sun is approximately 4.756 x 10^11 meters.

The height of the image is approximately 1.066 cm, and since it is negative, it means that the image is inverted and smaller than the object.

Using the thin lens equation:

1/f = 1/d_o + 1/d_i

where f is the focal length of the lens, d_o is the object distance, and d_i is the image distance.

Plugging in the given values, we get:

1/4 = 1/16 + 1/d_i

Solving for d_i, we get:

d_i = 3.2 cm

Using the magnification equation:

m = -d_i/d_o

where m is the magnification of the image.

Plugging in the given values, we get:

m = -3.2/16 = -0.2

Since the magnification is negative, the image is inverted.

Finally, using the equation:

m = h_i/h_o

where h_i is the height of the image, and h_o is the height of the object.

Plugging in the given values and solving for h_i, we get:

h_i = m * h_o = (-0.2) * 5.33 cm = -1.066 cm

Therefore, the height of the image is approximately 1.066 cm, and since it is negative, it means that the image is inverted and smaller than the object.

The time taken for the coffee to cool from 93°C to 73°C is approximately 36.1 minutes.

The cooling law is given by:

$$\frac{dQ}{dt}=-k(T-T_0)$$

where Q is the heat in the object, t is the time taken, T is the temperature of the object at time t, T0 is the temperature of the environment and k is a constant known as the cooling constant.

We need to find the time it takes for the coffee to reach a drinking temperature of 73°C given that its initial temperature is 93°C.

Therefore, we need to find the time it takes for the coffee to cool down from 93°C to 73°C when placed in a room temperature of 18°C.

Let’s assume that the heat energy that is lost by the coffee is equal to the heat energy gained by the environment. We can express this as:

dQ = - dQ where dQ is the heat energy gained by the environment.

We can substitute dQ with C(T-T0) where C is the specific heat capacity of the object.

We can rearrange the equation as follows:

$$-\frac{dQ}{dt}=k(T-T_0)$$

$$-\frac{d}{dt}C(T-T_0)=k(T-T_0)$$

$$\frac{d}{dt}T=-k(T-T_0)$$

The differential equation above can be solved using separation of variables as follows:

$$\frac{d}{dt}\ln(T-T_0)=-k$$

$$\ln(T-T_0)=-kt+c_1$$

$$T-T_0=e^{-kt+c_1}$$

$$T=T_0+Ce^{-kt}$$

where C = e^(c1).

We can now use the values given to find the specific value of C which is the temperature difference when t=0, that is, the temperature difference between the initial temperature of the coffee and the room temperature.

$$T=T_0+Ce^{-kt}$$

$$73=18+C\cdot e^{-0.09t}$$

$$55=C\cdot e^{-0.09t}$$

$$C=55e^{0.09t}$$

$$T=18+55e^{0.09t}$$

We can now solve for the value of t when T=93 as follows:

$$93=18+55e^{0.09t}$$

$$e^{0.09t}=\frac{93-18}{55}$$

$$e^{0.09t}=1.3636$$

$$t=\frac{\ln(1.3636)}{0.09}$$

Objects made of steel or concrete do not always have more mass than objects made of plastic or styrofoam. The mass of an object depends on its volume and the density of the material it is made of.

Objects made of steel or concrete do not always have more mass than objects made of plastic or styrofoam. Mass refers to the amount of matter in an object, and it is not determined solely by the material it is made of. The mass of an object depends on its volume and the density of the material.

While steel and concrete are generally denser than plastic or styrofoam, it doesn't mean they always have more mass. For example, a small steel ball may have less mass than a large plastic ball. Similarly, a concrete block may have more mass than a styrofoam block of the same size, but it doesn't mean all steel or concrete objects will have more mass than all plastic or styrofoam objects.

To determine the mass of an object, you need to consider its volume and the density of the material. Mass can be calculated using the formula mass = density x volume. So, even though steel and concrete are typically denser materials, the size or volume of the object also plays a crucial role in determining its mass.

Answer:

The bird and the arrow are 84.621 meters far from the hunter.

Explanation:

The arrow experiments of a parabolic motion, which is the combination of horizontal motion at constant velocity and vertical uniform accelerated motion. The arrow strikes the bird when it reaches its maximum height. First, we determined the time taken by the arrow before striking the bird:

\(v = v_{o}\cdot \sin \theta + g\cdot t\) (1)

Where:

\(v_{o}\) - Initial speed of the arrow, in meters per second.

\(v\) - Final speed of the arrow, in meters per second.

\(\theta\) - Launch angle, in sexagesimal degrees.

\(g\) - Gravitational acceleration, in meters per square second.

\(t\) - Time, in seconds.

If we know that \(v_{o} = 40\,\frac{m}{s}\), \(\theta = 30^{\circ}\), \(g = -9.807\,\frac{m}{s^{2}}\), \(v = 0\,\frac{m}{s}\), then the time taken by the arrow is:

\(t = \frac{v-v_{o}\cdot \sin \theta}{g}\)

\(t = \frac{0\,\frac{m}{s}-\left(40\,\frac{m}{s}\right)\cdot \sin 30^{\circ} }{-9.807\,\frac{m}{s^{2}} }\)

\(t = 2.039\,s\)

And the initial horizontal distance of the arrow (\(x_{i}\)) is determined by this kinematic formula:

\(x_{i} = (v_{o}\cdot \cos \theta)\cdot t\) (2)

If we know that \(v_{o} = 40\,\frac{m}{s}\), \(\theta = 30^{\circ}\) and \(t = 2.039\,s\), then the initial horizontal distance is:

\(x_{i} = \left[\left(40\,\frac{m}{s} \right)\cdot \cos 30^{\circ}\right]\cdot (2.039\,s)\)

\(x_{i} = 70.633\,m\)

There is an inelastic collision between the arrow and the bird, the initial velocity of the bird-arrow system is:

\(v = \frac{m_{A}\cdot v_{o}\cdot \cos \theta}{m_{A}+m_{B}}\) (3)

Where:

\(v\) - Initial velocity of the bird-arrow system, in meters per second.

\(m_{A}\) - Mass of the arrow, in kilograms.

\(m_{B}\) - Mass of the bird, in kilograms.

If we know that \(m_{A} = 0.5\,kg\), \(m_{B} = 2\,kg\), \(v_{o} = 40\,\frac{m}{s}\) and \(\theta = 30^{\circ}\), then the initial velocity of the bird-arrow system is:

\(v = \frac{(0.5\,kg)\cdot \left(40\,\frac{m}{s} \right)\cdot \cos 30^{\circ}}{0.5\,kg + 2\,kg}\)

\(v = 6.928\,\frac{m}{s}\)

And the maximum height reached by the arrow (\(y\)), in meters, is:

\(y = y_{o} + (v_{o}\cdot \sin \theta)\cdot t +\frac{1}{2}\cdot g\cdot t^{2}\) (4)

Where \(y_{o}\) is the initial height of the arrow, in meters.

If we know that \(y_{o} = 0\,m\), \(v_{o} = 40\,\frac{m}{s}\), \(\theta = 30^{\circ}\),  \(g = -9.807\,\frac{m}{s^{2}}\) and \(t = 2.039\,s\), then the maximum height reached by the arrow is:

\(y = 0\,m + \left(40\,\frac{m}{s} \right)\cdot (2.039\,s)\cdot \sin 30^{\circ} +\frac{1}{2}\cdot \left(-9.807\,\frac{m}{s^{2}}\right)\cdot (2.039\,s)^{2}\)

\(y = 20.394\,m\)

Time needed by the bird-arrow system to land is determined by this expression based on (4):

\(y = y_{o} + (v_{o,y})\cdot t +\frac{1}{2}\cdot g\cdot t^{2}\)

If we know that \(y_{o} = 20.394\,m\), \(y = 0\,m\), \(v_{o,y} = 0\,\frac{m}{s}\) and \(g = -9.807\,\frac{m}{s^{2}}\), then the time needed to land is:

\(0\,m = 20\,m + \left(0\,\frac{m}{s} \right)\cdot t + \frac{1}{2}\cdot \left(-9.807\,\frac{m}{s^{2}} \right)\cdot t^{2}\)

\(t = 2.019\,s\)

And the horizontal distance travelled by the bird-arrow system (\(x_{ii}\)), in meters, is calculated from a formula based on (2):

\(x_{ii} = v_{o, x}\cdot t\)

If we know that \(v_{o,x} = 6.928\,\frac{m}{s}\) and \(t = 2.019\,s\), then the distance travelled by the bird-arrow system is:

\(x_{ii} = \left(6.928\,\frac{m}{s} \right)\cdot (2.019\,s)\)

\(x_{ii} = 13.988\,m\)

The final distance of the bird-arrow system from the hunter is:

\(x = x_{i} + x_{ii}\)

\(x = 70.633\,m + 13.988\,m\)

\(x = 84.621\,m\)

The bird and the arrow are 84.621 meters far from the hunter.

The current flowing through the hair dryer is 10 Amperes (A).

To calculate the current flowing through the hair dryer, we can use Ohm's Law, which states that current (I) is equal to power (P) divided by voltage (V). Mathematically, it can be expressed as:

I = P / V

Given:

Power (P) = 1100 W

Voltage (V) = 110 V

Using the formula, we can calculate the current (I):

I = 1100 W / 110 V

I = 10 Amperes (A)

Ohm's Law is a fundamental principle in electrical engineering and physics that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor. It is named after the German physicist Georg Simon Ohm, who formulated the law.

Mathematically, Ohm's Law can be expressed as:

V = I * R

Where:

- V represents the voltage across the conductor (measured in volts, V).

- I represents the current flowing through the conductor (measured in amperes, A).

- R represents the resistance of the conductor (measured in ohms, Ω).

According to Ohm's Law, the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance. In other words, if the voltage increases, the current will increase, assuming the resistance remains constant. Conversely, if the resistance increases, the current will decrease for a given voltage.

Ohm's Law is commonly used in analyzing and designing electrical circuits, as it provides a simple relationship between voltage, current, and resistance. It serves as the foundation for understanding various electrical phenomena and is widely applied in fields such as electronics, power systems, and telecommunications.

The new volume of the gas can be found by considering the two given processes separately. First, when the pressure is halved at constant temperature, we can apply Boyle's Law, which states that the pressure and volume of an ideal gas are inversely proportional when temperature is held constant.

Therefore, if the pressure is halved, the volume of the gas will double. Second, when the initial absolute temperature is doubled at constant pressure, we can apply Charles's Law, which states that the volume and temperature of an ideal gas are directly proportional when pressure is held constant.

Therefore, if the temperature is doubled, the volume of the gas will also double. Since the volume doubled in both processes, we can conclude that the new volume of the gas, in terms of the original volume, is 2 times 2, which is 4 times the original volume.

Therefore the new volume of the gas is 4 times the original volume.
