arlik [135]

Answer:

4 ft/s^2

Explanation:

If the velocity is 8ft/s after 2s then to find the acceleration you would use the formula:

\frac{v_f - v_{i} {}}{t} =a

sooooooooo

\frac{8 ft/s - 0 ft/s }{2 s} = \frac{8 ft/s }{2 s} = 4 ft/s^{2}

2. A linearly-polarized em wave moving in vacuum perpendicular to a perfectly reflecting surface exerts a radiation pressure of
dusya [7]

Answer:

The intensity of that em eave is 1554\times10^{8}\ W/m^2

Explanation:

Given that,

Pressure = 518 Pa

We need to calculate the intensity of that em eave

Using formula of pressure

P=\dfrac{I}{c}

I=Pc

Where,I =  intensity of em eave

c = speed of light

P = pressure

Put the value into the formula

I=518\times3\times10^{8}

I=1554\times10^{8}\ W/m^2

Hence, The intensity of that em eave is 1554\times10^{8}\ W/m^2
