Answer:
3.125J
Explanation:
K.E.= 1/2(mass)(velocity)^2
K.E.=1/2(0.25)(5)^2=3.125
Answer:
e) half
Explanation:
as we know relation b/w charge(Q) , capacitance (C) and voltage (V) is
Q = CV ...........(i)
we also know capacitance of a capacitor for separation d and area A is
C = ∈₀A/d ...........(ii)
from the above equation it is clear that C is inversely proportional to separation if separation doubled capacitance will reduced to half and from equation first charge is directly proportional to capacitance.
that s why magnitude of charge will reduced to half
so option (e) is right answer
a.the amount of sunlight increases.
Explanation:
As a submarine rises to the surface, the change it encounters that is true from the given options is that the amount of sunlight increases.
The bottom of the ocean is dark and receives little to no sunlight due to the scattering of the rays by ocean water.
- As the submarine rises, the volume of water column on it decreases and the pressure on it decreases too.
- Also, the temperature rises steadily to the surface.
