Explanation:Watt=NM/s=J/s=kgm²/s³=hP
Answer :B,kgm²/s³
Answer:
1.98 × 10⁻³³m
Explanation:
It is given that,
Mass of the bullet, m = 27 g = 0.027 kg
Velocity of bullet, v = 800 m/s
The uncertainty in momentum is 0.20%. The momentum of the bullet is given by :

Uncertainty in momentum is,

We need to find the uncertainty in position. It can be calculated using Heisenberg uncertainty principal as :

Answer:
Explanation:
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays

Answer:
The correct option is;
B. Subtract vectors A from C;
= 12 N
Explanation:
The given parameters are;
The weight of the dresser = 250 N
The force applied by the man = 20 N = C
The frictional force provided by the carpet = 8 N = The component of the weight resisting motion = A
Therefore, the net force tending to put the dresser in motion,
, is given as follows;
= The force applied by the man, C - The frictional force provided by the carpet which is the component of the weight resisting motion, A
= C - A = 20 N - 8 N = 12 N
= 12 N
The resulting net force,
= 12 N.
