The impulse (J) is defined as the product of the force (F) and the time (Δt) for which it is applied:

J = FΔt

Substituting the given values, we get:

J = 10 N × 2.5 s = 25 N·s

Therefore, the impulse when an average force of 10 N is exerted on a cart for 2.5 s is 25 N·s.

Answer:

v₃ = 9.62[m/s]

Explanation:

To solve this type of problem we must use the principle of conservation of linear momentum, which tells us that the momentum is equal to the product of mass by velocity.

We must analyze the moment when the astronaut launches the toolkit, the before and after. In order to return to the ship, the astronaut must launch the toolkit in the opposite direction to the movement.

Let's take the leftward movement as negative, which is when the astronaut moves away from the ship, and rightward as positive, which is when he approaches the ship.

In this way, we can construct the following equation.

\(-(m_{1}+m_{2})*v_{1}=(m_{1}*v_{2})-(m_{2}*v_{3})\)

where:

m₁ = mass of the astronaut = 157 [kg]

m₂ = mass of the toolkit = 5 [kg]

v₁ = velocity combined of the astronaut and the toolkit before throwing the toolkit = 0.2 [m/s]

v₂ = velocity for returning back to the ship after throwing the toolkit [m/s]

v₃ = velocity at which the toolkit should be thrown [m/s]

Now replacing:

\(-(157+5)*0.2=(157*0.1)-(5*v_{3})\\(5*v_{3})= 15.7+32.4\\v_{3}=9.62[m/s]\)

The velocity with which the astronaut must throw the tool kit is 9.62 m/s.

The given parameters:

Apply the principle of conservation of linear momentum to determine the velocity of the tool kit;

\(m_1 u_1 + m_2u_2 = v(m_1 + m_2)\\\\-0.1(157) \ + 5u_2 = 0.2(157 + 5) \\\\-15.7 + 5u_2 = 32.4\\\\5u_2 = 32.4 + 15.7\\\\5u_2 = 48.1\\\\u_2 = \frac{48.1}{5} \\\\u_2 = 9.62 \ m/s\)

Thus, the velocity with which the astronaut must throw the tool kit is 9.62 m/s.

A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.

A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.

the 4.40 μF capacitor in series with the 5.80 kΩ resistor and 150 V emf source will charge up to 63.2% of its maximum voltage after one time constant, and will approach 150 V after several time constants.

When the emf source is connected to the circuit, current will start to flow and charge will begin to accumulate on the capacitor. The rate of charging will be determined by the time constant of the circuit, which is equal to the product of the resistance and capacitance (RC). In this case, the time constant is:

RC = 5.80 kΩ * 4.40 μF = 25.52 ms

After one time constant (25.52 ms), the capacitor will have charged to approximately 63.2% of its maximum voltage. After two time constants, it will have charged to approximately 86.5% of its maximum voltage, and after three time constants it will have charged to approximately 95% of its maximum voltage.

The maximum voltage that the capacitor will reach is equal to the emf of the source (150 V) because there is negligible internal resistance in the source. Therefore, the capacitor will eventually charge to 150 V, but it will take multiple time constants to get close to this value.

The question addresses the stability of the atmosphere and the factors that determine convective stability or instability. It also explains the difference between the adiabatic lapse rate of dry air and wet saturated air.

a) The stability of the atmosphere is determined by the temperature profile and relative densities of the air cell and atmosphere. If the temperature of the surrounding atmosphere decreases with altitude at a rate greater than the adiabatic lapse rate of the air cell, the atmosphere is considered convectively stable.

In this case, the air cell will return to its original position. Conversely, if the temperature of the surrounding atmosphere decreases slower than the adiabatic lapse rate of the air cell, the atmosphere is convectively unstable. The air cell will continue moving in the same direction.

b) The adiabatic lapse rate refers to the rate at which temperature decreases with altitude for a parcel of air lifted or descending adiabatically (without exchanging heat with its surroundings). The adiabatic lapse rate of dry air is higher (around \(9.8^0C\) per kilometer) compared to the adiabatic lapse rate of wet saturated air (around 5°C per kilometer).

This difference arises because when water vapor condenses during the ascent of saturated air, latent heat is released, reducing the rate of temperature decrease. A diagram can illustrate the difference between the two lapse rates, showcasing their respective slopes.

c) When wet unsaturated air rises from the ocean surface, its temperature decreases at a rate equal to the dry adiabatic lapse rate. However, if the ambient lapse rate (temperature decrease with altitude) is higher than the adiabatic lapse rate for dry air, a temperature inversion layer forms at higher altitudes.

In this inversion layer, the temperature increases with altitude instead of decreasing. A schematic diagram can depict the temperature changes of the wet air in comparison to the ambient temperature, showing the inversion layer.

Cumulus clouds form at the altitude where the rising moist air reaches the level of the temperature inversion layer. These clouds are formed due to the condensation of water vapor as the air parcel cools to its dew point temperature.

The mass of the rock is approximately 86.304 tons.

To convert the mass of the rock from grams to tons, we can use the conversion factor that 1 ton is equal to 907.2 kilograms.

Mass of the rock = 7.84 x 10^7 grams

To convert grams to kilograms, we divide by 1000:

Mass in kilograms = (7.84 x 10^7 grams) / 1000 = 7.84 x 10^4 kilograms

Now, to convert kilograms to tons, we divide by 907.2:

Mass in tons = (7.84 x 10^4 kilograms) / 907.2 = 86.304 tons

The terminal voltage of a cell is less than its emf because of the internal resistance of the cell.

The voltage of the cell is commonly called the emf, or electromotive force. The energy of the cell, which is supplied by the chemical reactions that take place inside it, is represented by this voltage. The terminal voltage of a cell is the voltage that is present at the ends of the cell's terminals when the cell is connected to a circuit. When a cell is connected to a circuit, the current that flows through it experiences some resistance. This resistance causes the voltage that is present at the terminals of the cell to decrease. As a result, the terminal voltage of the cell is lower than its emf. The resistance is due to the internal resistance of the cell, which is the resistance of the cell's components to the flow of current. The internal resistance of the cell is caused by the cell's components, such as the electrodes and electrolytes. This resistance is always present, regardless of whether the cell is connected to a circuit or not. When the cell is connected to a circuit, the internal resistance is in series with the external resistance of the circuit. This causes the voltage that is present at the terminals of the cell to decrease.

When a cell is connected to a circuit, it is possible for the voltage that is present at the terminals of the cell to be less than the emf of the cell. This happens because of the internal resistance of the cell, which is always present. The internal resistance is caused by the components of the cell, such as the electrodes and electrolyte. This resistance is always present, regardless of whether the cell is connected to a circuit or not.When the cell is connected to a circuit, the internal resistance is in series with the external resistance of the circuit. This causes the voltage that is present at the terminals of the cell to decrease. The voltage drop that is caused by the internal resistance is directly proportional to the current that flows through the cell. As the current that flows through the cell increases, the voltage drop that is caused by the internal resistance also increases.

In conclusion, the terminal voltage of a cell is less than its emf because of the internal resistance of the cell. This resistance is caused by the components of the cell, such as the electrodes and electrolyte. When the cell is connected to a circuit, the internal resistance is in series with the external resistance of the circuit.

Answer:

that the acceleration is negative therefore it is directed to the left.

Explanation:

To find the acceleration of a system we must use Newton's second law

          ∑ F = m a

To apply this equation to our case we set a reference system where the direction to the right is positive.

We have 3 forces, a force F₁ = -20 N, a negative sign indicates that it is directed to the left, two forces F₂ and F₃ of magnitude 8N each directed to the right.

We substitute

            -F₁ + F₂ + F₃ = m a

           - 20 +8 + 8 = m a

             -4 = m a  

             a = -4 / m

Here we can see that the acceleration is negative therefore it is directed to the left.

Answer:

The magnitude of the boy's displacement is 24.698 paces which is in the direction of approximately 58.24° North of East

Explanation:

The given parameters are;

The distance West the boy on a treasure hunt walks = 12 paces

The distance North the boy on a treasure hunt then walks = 21 paces

The distance East the boy on a treasure hunt then walks = 25 paces

Writing the displacement in vector format, gives;

d = -12·i + 21·j + 25·i

Which gives

d = 13·i + 21·j

The magnitude of the boy's resultant displacement is given as follows;

\(\left | \mathbf{d} \right | = \sqrt{d_x^2 + d_y^2}\)

Where;

\(d_x = 13, \ d_y = 21\)

\(\left | \mathbf{d} \right | = \sqrt{13^2 + 21^2} = \sqrt{610} \approx 24.698 \ paces\)

The magnitude of the boy's displacement is 24.698 paces

The direction of the displacement is tan⁻¹(21/13) ≈ 58.24° North of East.

a) Sketch the plate shape: we get a shape that resembles a trapezoid.

The plate shape is determined by the lines y = 2 - x² and y = 2x - 1. To sketch the plate shape, we can plot these two lines and shade the region in between them. The intersection points of the lines are found by solving the equations simultaneously:

2 - x² = 2x - 1

Simplifying, we get:

x² + 2x - 3 = 0

Factoring, we have:

(x - 1)(x + 3) = 0

So, x = 1 and x = -3. Plugging these values into the equations of the lines, we find the corresponding y-values:

For x = 1:

y = 2 - (1)² = 1

For x = -3:

y = 2(-3) - 1 = -7

Plotting these points and connecting them with the lines, we get a shape that resembles a trapezoid.

b) Total charge through the double integral:

To find the total charge Q, we need to integrate the charge density p(x, y) over the entire plate. We can express this as a double integral:

Q = ∬ p(x, y) dA

c) Reducing the double integral to repeated integrals: The limits of integration for x are the values of x that define the boundaries of the plate shape, which are -3 to 1.

Since the plate shape is described by the lines y = 2 - x² and y = 2x - 1, we can rewrite the double integral as a repeated integral by integrating with respect to x and y separately:

Q = ∫∫ p(x, y) dy dx

The limits of integration for y are from the lower curve y = 2 - x² to the upper curve y = 2x - 1. The limits of integration for x are the values of x that define the boundaries of the plate shape, which are -3 to 1.

d) Calculating the integral: The total charge Q of the thin plate is approximately 12.4 mC.

Now, we can evaluate the double integral to find the total charge Q:

Q = ∫(-3 to 1) ∫(2 - x² to 2x - 1) x²y dy dx

Performing the inner integral with respect to y first, we get:

Q = ∫(-3 to 1) [x²(y²/2 - y)] from 2 - x² to 2x - 1 dx

Simplifying the inner integral, we have:

Q = ∫(-3 to 1) [(x²/2)(2 - x²) - x²(2x - 1)] dx

Expanding and simplifying further, we get:

Q = ∫(-3 to 1) (x² - x⁴/2 - 4x³ + 2x²) dx

Integrating term by term, we have:

Q = [x³/3 - x⁵/10 - x⁴ + 2x³/3] from -3 to 1

Evaluating the integral at the limits, we get:

Q ≈ 12.4 mC (rounded to five significant figures)

Therefore, the total charge Q of the thin plate is approximately 12.4 mC.

Explanation:

The magnitude of the acceleration of the body is approximately 1.802 m/s^2 when forces of magnitude 5 Newton and 4 Newton act on a body of mass 4.0 kg at a right angle to each other.

To determine the magnitude of the acceleration of a body when two forces act on it at a right angle, we can use the Pythagorean theorem and Newton's second law of motion.Newton's second law states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). In this case, the net force is the vector sum of the two forces acting on the body.Using the Pythagorean theorem, we can find the magnitude of the net force. Let's call the force with magnitude 5 Newton as F1 and the force with magnitude 4 Newton as F2. The net force (Fnet) can be calculated as the square root of the sum of the squares of the individual forces: Fnet = sqrt(F1^2 + F2^2).Now we can substitute the net force into Newton's second law to find the acceleration (a). Rearranging the formula, we have a = Fnet / m.Plugging in the values, Fnet = sqrt(5^2 + 4^2) = sqrt(25 + 16) = sqrt(41) Newtons. The mass (m) is given as 4.0 kg.

Finally, the magnitude of the acceleration of the body is calculated as a = Fnet / m = sqrt(41) / 4.0 ≈ 1.802 m/s^2.
