Mass of the block = 2/g = 2/9.8 =0.204 kg.
Frictional force = mass * acceleration
a = F/ m where F is the frictional force = 2.4
a = 2.4/ 0.204 = 11.76 m/s^2
Answer:
A. 4.47 m/s
Explanation:
As the ball oscillates, it mechanical energy, aka the total kinetic and elastics energy stays the same. For the ball to be at maximum speed, its elastic energy i 0 and vice versa. When the ball is at rest, its kinetic energy is 0 and its elastic energy is at maximum at 50 cm, or 0.5 m
1500 g = 1.5 kg
Answer:
Explanation:
As we know that due to a thin sheet electric field at a point near its surface is given as
now we have two sheets of opposite charges so the net electric field is double that of field due to one sheet
so we have
now we have
Answer:
the three types of matter are solid, liquid, gas
