Answer:
v = 0.84 m/s
Explanation:
given,
R = 12 cm
M (mass of pulley )= 520 g
m (mass of block)= 20 g
s = 50 cm = 0.5 m
using conservation of energy
Potential energy = Kinetic energy
and v = r ω
v = √0.7
v = 0.84 m/s
Answer:
They will become aligned according to the charges on the metal plate.
Explanation:
When Polar molecules are placed between oppositely charged metal plates the molecules will tend to be attracted by their corresponding oppositely charged plates that is the positive and negative plates,
A polar molecule is one which has opposite charges on its ends. Non-polar molecules however do not have charges on their end
Explanation:
KE = ½ mv²
130,048 J = ½ m (16 m/s)²
m = 1016 kg
Answer:
