Answer:
Gravitational potential=mgh
=50×10×2.5
=1250J
option a
A :-) for this question , we should apply
F = ma
( i ) Given - m = 2 kg
a = 15 m/s^2
Solution :
F = ma
F = 2 x 15
F = 30 N
( ii ) Given - m = 2 kg
a = 10 m/s^2
Solution :
F = ma
F = 2 x 10
F = 20 N
.:. The net force of object ( i ) has greater force compared to object ( ii ) by
( 30 - 20 ) 10 N
Answer:
A rabbit which needs food specifically food from plants because they are vegetarians, to help them grow. The energy that the plant holds is given to the rabbit when eaten. The plant feeds the bunny its nutrients which tells the muscles to keep going and get stronger and tells the rest of the body to grow.

Answer:
θr will increase.
Explanation:
We know that when light travel from one medium to another medium the relationship between refractive index and angle given as
na. sinθa = nb . sinθr
If na is increased (by using a different type of glass) but θa is kept the same then sinθr will also increase.
So answer is θr will increase.
Answer:
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
