Answer:
momentum formula = Mass × Velocity
Answer:
The apparent weight is the weight of the body minus the weight of the liquid displaced. The body will float only when both the weights are same. In this case, the given body of weight W is floating and hence the apparent weight is zero.
Answer:
Option (2) : Sixteen times the first cube
Explanation:
Explanation:
The given data is as follows.
q = 6.0 nC =
inner radius (r) = 1.0 cm = 0.01 m (as 1 cm = 100 m)
So, there will be same charge on the inner surface as the charge enclosed with an opposite sign.
Formula to calculate the charge density is as follows.
.......... (1)
Since, area of the sphere is as follows.
A = ........... (2)
Hence, substituting equation (2) in equation (1) as follows.
=
=
or, = 4.77
Thus, we can conclude that the resulting charge density on the inner surface of the conducting sphere is 4.77 .
"Weight" is the gravitational attraction between you and something else.
In our daily life, it's always the gravitational attraction between us and
the Earth. But when a person or an object is on the moon or a different
planet, then the "something else" is something else ... not the Earth.
On the moon, the weight of anything is about 17% of its Earth-weight.
