Answer:
Ohms law state that the current I flowing through a metallic conductor is directly proportional to the potential difference V across its end, provided that all physical condition are kept constant i.e temperature
Explanation:
that is, V varies directly to I
Where,
V= potential difference in volt and
I = current in Ampere (A)
therefore,
V= IR and R is measured in ohm
Momentum=mass × velocity
momentum= 200×30
=6000kgm/s
D. distance
A light-year is the distance light would travel in 1 year.
Let h = the distance from the edge of the wall to the water surface (m).
Use g = 9.8 m/s² and neglect air resistance.
The initial vertical velocity of the pebble is zero.
Because the pebble hits the surface of the water after 1.5 s, therefore
h = (1/2)*(9.8 m/s²)*(1.5 s)² = 11.025 m
Answer: 11.025 m
