The potential energy of the block is A) 490 J
Explanation:
The potential energy of an object is the energy possessed by the object due to its position in the gravitational field.
It is calculated as follows:
where
m is the mass of the object
g is the acceleration due to gravity
h is the height of the object above the ground
For the block in this problem, we have:
m = 10 kg
h = 5 m
Therefore, its potential energy is:

Answer:
E = 58.7 V/m
Explanation:
As we know that flux linked with the coil is given as
here we have
now we have
now the induced EMF is rate of change in magnetic flux
now for induced electric field in the coil is linked with the EMF as
Mass is the amount of matter it has, while weight <span>is a measurement of the force placed on an object by gravity. An example of how they are different is that mass is always constant while weight varies depending on the location.</span>
The correct answer is B.Antartica and Australia were one landmass millions of years ago.
