KE = 1/2 * m * v2
We have to rearrange this so the subject is mass. (because the question asks for the mass of the object) :
Mass = (2 * KE) / v
Now input the values into this equation to get your answer :
Mass = (2 * KE) / v
Mass = (2 * 480) / 8
Mass = 960 / 8
Mass = 120

Answer: It is correct to say iron is heavier than the wood.
Explanation:
It's because the density of iron is more than wood. What is this mean is iron the space between iron molecules in iron much less than as that of wood. So in iron there is more molecules than wood in same volume. More molecules means more mass, that's why iron is much heavier than wood for same volume.
(a) The electric field strength between two parallel conducting plates does not exceed the breakdown strength for air (
)
(b) The plates can be close together to 1.7 mm with this applied voltage
<u>Explanation:</u>
Given data:
Dielectric strength of air = 
Distance between the plates = 2.00 mm = 
Potential difference, V = 
We need to find
a) whether the electric field strength between two parallel conducting plates exceed the breakdown strength for air or not
b) the minimum distance at which the plates can be close together with this applied voltage.
The voltage difference (V) between two points would be equal to the product of electric field (E) and distance separation (d). The equation form is and apply all given value,

From the above, concluding that The electric field strength between two parallel conducting plates (
) does not exceed the breakdown strength for air (
)
b) To find how close together can the plates be with this applied voltage:
The formula would be,

Apply all known values, we get
