What is the strength of the electric field between two parallel conducting plates separated by 1.00 cm and having a potential di
raketka [301]

Answer:

E=3.22*10^6 N/C

Explanation:

From the question we are told that:

Separation Distance d=1.0cm =0.01m

Potential difference V=3.22 * 10^4 V

Generally the equation for Electric Field strength is mathematically given by

 E=\frac{v}{d}

 E=\frac{3.22*10^4}{0.01}

 E=3.22*10^6 N/C

The motorcycle travels with a constant speed v0 along the path that, for a short distance, takes the form of a sine curve. Deter
Alexandra [31]

Let at any instant of time the speed is vo and the angle made by the bike with the horizontal is given

now we have

component of speed in x direction given as

v_x = v_0cos\theta

component of speed in y direction will be

v_y = v_0sin\theta

now from above two equations we can say that here

\theta = angle with the horizontal at any instant

and since here it is a sine curve so we know that

y = sin(x)

so we have slope of graph

tan\theta = \frac{dy}{dx} = cos(x)

A force of 52N acts upon a 4kg block sitting on the ground. Calculate the acceleration of the object.​
irina1246 [14]

Answer:

a=13\ m/s^2

Explanation:

Given that,

Force, F = 52 N

Mass of the block, m = 4 kg

We need to find the acceleration of the object. We know that,

F = ma

Put the values,

a=\dfrac{F}{m}\\\\a=\dfrac{52}{4}\\\\a=13\ m/s^2

So, the acceleration of the object is equal to 13\ m/s^2.

Sam noticed every time she rolled a ball on a flat surface it did not stop unless she applied a force on it. This happened multi
blsea [12.9K]
Because the ball is a sphere and there's nothing that can actually stop a sphere unless you cover it with something that will actually stop it, for example like your hand.

A car is moving from rest and attained a velocity of 80 m/s. Calculate the acceleration of the car after 5 s?
soldi70 [24.7K]

Answer:

400 m/s

Explanation:

If it is moving at a velocity of 80 m/s from rest, then after 5 s it would be at 400 m/s.

80 x 5 = 400
