a cube with an electric field passing through it is shown on the right. if the energy per time is 8 watts and the size of the cube is 10m x 10m x 10m. what is the strength of the electric field, e 0?

Answer:

2.89 m/s²

Explanation:

From the question given above, the following data were obtained:

Radius (r) = 100 m

Velocity (v) = 17 m/s

Acceleration (a) =.?

The acceleration of a circular motion is defined by:

a = v²/r

Where:

a is the acceleration.

v is the velocity.

r is the radius.

With the above formula, we can obtain the acceleration of the car as follow:

Radius (r) = 100 m

Velocity (v) = 17 m/s

Acceleration (a) =.?

a = v²/r

a = 17²/ 100

a = 289/100

a = 2.89 m/s²

Therefore, the acceleration of the car is 2.89 m/s²

Answer:

The wavelength of the wave would increase to 10 meters.

Explanation:

We can use the formula:

velocity = frequency × wavelength

to relate the velocity, frequency, and wavelength of a wave.

Given that the wave has a speed of 20 m/s and a wavelength of 5 meters, we can solve for its frequency as follows:

frequency = velocity ÷ wavelength = 20 m/s ÷ 5 meters = 4 Hz

Now, if the same wave is created in the same medium, but with half the original frequency, its new frequency will be:

new frequency = 4 Hz ÷ 2 = 2 Hz

To find the new wavelength of the wave, we can rearrange the formula above to solve for wavelength:

wavelength = velocity ÷ frequency

Using the new frequency of 2 Hz, we get:

new wavelength = 20 m/s ÷ 2 Hz = 10 meters

Therefore, if the same wave was created in the same medium, with half the original frequency, the wavelength of the wave would increase to 10 meters.

A capacitor is a device that stores electrical energy in an electric field. The unit of capacitance is farads (F). A 10μF capacitor charged to 5V implies that\(Q = CV, where C = 10μF and V = 5V, therefore Q = (10 × 10^-6) × 5 = 50μC.\)

The voltage across the capacitor is maximum since it is fully charged. At time t = 0, a current of 2μA starts to flow out of the capacitor through a resistor. The voltage across the capacitor starts to decrease as a result of the current. The voltage across the capacitor varies with time.

The voltage across a capacitor is given by the equation below:V = V₀e^(-t/RC), whereV₀ is the initial voltage on the capacitor. R is the resistance of the resistor and C is the capacitance of the capacitor. t is time measured in seconds.Since the voltage across the capacitor is 5V, we substitute \(V₀ with 5V. RC = 10 × 10^-6 × R, therefore V = 5e^(-t/10R). To plot the graph, we set R equal to 1kΩ.\)

Explanation:

Given that,

The mechanical advantage of a lever, m = 3

Input force, \(F_i=100\ N\)

We need to find the output force. The ratio of output force to the input force is called the mechanical advantage of the lever. So,

\(m=\dfrac{F_o}{F_i}\\\\F_o=m\times F_i\\\\F_o=3\times 100\\\\F_o=300\ N\)

So, the output force is 300 N.

Its position of this particle D must be near the positive y-axis in the second meiotic division of the aforementioned equations.

This attraction that earth has on an object is referred to as gravitational force. Examples of motion brought on by gravitational force also include upwards motion of a ball being thrown, the downward motion of water moving through a stream, and the pull of gravity on river flow.

When two bodies are separated by a distance R and have masses M and m, the gravitational attraction between them is:

F= GMm/R²

The gravitational force is a result of the interaction between the gravitational forces exerted by particle B and particle C on particle A.

We can claim that because particle B has a larger mass than particle A does, the gravitational force was closer to and roughly equal to the mass of the bodies.

The net gravitational force on particle A would be zero if particle D force is exerted that is equal to it and opposite to the normal Force that results.

As a result, particle D need to be positioned close to the positive y-axis in the second quadrant.

Answer:

the change in momentum is 2.52 N·s

the constant force on the ball while in contact with the players foot is 126 N

Explanation:

p=momentum

m=mass

v=change in velocity

p=(0.42)(6)

p=2.52

The change in the ball's momentum is 2.52 kgms⁻¹

The constant force exerted by the players foot on the ball is 126 N

From the question,

We are to determine the change in momentum of the ball

Change in momentum calculated by using the formula,

\(\rho = m(v-u)\)

Where \(\rho\) is the change in momentum

\(m\) is the mass

\(v\) is the final velocity

and \(u\) is the initial velocity

From the given information,

\(m = 0.42 \ kg\)

\(u = 12 \ m/s\)

\(v = 18 \ m/s\)

Therefore,

Change in the ball's momentum,

\(\rho = 0.42 (18-12)\)

\(\rho = 0.42 (6)\)

\(\rho = 2.52 \ kgms^{-1}\)

Hence, the change in the ball's momentum is 2.52 kgms⁻¹

For the force exerted by the players foot

Force is given by change in momentum with time

That is,

\(F = \frac{\rho}{t}\)

Where

\(F\) is the force

\(\rho\) is the change in momentum

and \(t\) is the time

From the given information

\(t = 0.020 \ s\)

Therefore,

\(F = \frac{2.52}{0.020}\)

\(F = 126 \ N\)

Hence, the constant force exerted by the players foot on the ball is 126 N

When the syringe volume is suddenly cut in half, the pressure inside the syringe momentarily spikes above 200 kPa due to the compression of the gas inside the syringe.

The pressure is directly proportional to the volume of the gas and inversely proportional to its temperature. When the volume is suddenly reduced, the gas molecules are compressed and collide with each other, increasing the temperature and thus increasing the pressure. This sudden increase in pressure is known as the adiabatic compression.

Additionally, the sudden change in volume also causes turbulence within the syringe, leading to a further increase in pressure. This momentary spike in pressure can have potential consequences such as causing damage to delicate instruments or injuring the operator. Therefore, it is important to handle syringes with care and to be aware of the potential risks associated with sudden changes in volume.

Explanation:

Velocity is the displacement divided by the time;

   Velocity = \(\frac{displacement}{time}\)

It is a vector quantity that has magnitude and direction.

The choice that shows a change in direction is a correct specification of velocity.

A balloon floating up into the air at 1m/s shows no directional change.

Answer:

Explanation:

1) The time of flight equation for projectile motion can be used here to find total time in air.

t = 2vsin∅ / g

where v is speed, Ф is launch angle

t = 2×4×sin 60 / 9.8

t = 0.71 seconds

2) Distance where it hit the ground is called as range and has the following standard equation

D = v² sin2Ф/g

D = 4²sin 2×60 / 9.8

D = 1.41m

3) Maximum elevation is maximum time reached

h = v² sin²Ф / 2g

h = 4²sin² 60 / 2*9.8

h = 0.61 m

The integral of 1/(1 + x²) is (1/2)ln|1 + x²| + C where C is the constant of integration.

Integration is a mathematical process of finding the antiderivative of a function. To integrate the given expression 1/(1 + x²), we will use the substitution method.

Let u = 1 + x², du/dx = 2x dx, then dx = du/2x and the integral becomes:

∫1/(1 + x²) dx = ∫1/u * (1/2x) du= (1/2)∫1/u du

The antiderivative of 1/u is ln|u| + C, where C is the constant of integration.

Therefore, the final solution of the integral is (1/2)ln|1 + x²| + C.

Let us work through the steps:

Step 1:Let u = 1 + x² and then differentiate both sides with respect to x to obtain du/dx. du/dx = 2x

Substitute 2x dx = du into the integral ∫1/(1 + x²) dx to get the integral in terms of u:∫1/u * (1/2x) du = (1/2) ∫1/u du

Step 2:Calculate the antiderivative of 1/u, which is ln|u|. Thus, the final solution is (1/2)ln|1 + x²| + C, where C is the constant of integration. The constant C will vary depending on the initial conditions of the problem.
