Answer:

The acceleration and time are 1.95 m/s and 12.5 s.

Explanation:

Given that,

Speed = 80 ft/s =24.384 m/s

Distance = 500 ft =152.4 m

We need to calculate the acceleration

Using third equation of motion

v^2-u^2= 2as

a = \dfrac{v^2-u^2}{2s}

Where, u = initial velocity

v = final velocity

a = acceleration

s = distance

Put the value in the equation

a=\dfrac{(24.384)^2-0}{2\times152.4}

a=1.95\ m/s^2

We need to calculate the time

Using first equation of motion

v=u+at

t =\dfrac{v-u}{a}

t=\dfrac{24.384-0}{1.95}

t =12.5\ s

Hence, The acceleration and time are 1.95 m/s and 12.5 s.

What type of Gaussian surface is best to determine the electric field from a large (ignore edge effects) sheet of charge
iragen [17]

Answer:

Explanation: Choose a gaussian surface that goes through the point for which you want to know the electric field. Ideally, the surface is such that the electric field is constant in magnitude and always makes the same angle with the surface so that the flux integral is straightforward to evaluate
