Answer:
Momentum of the object = 15 kg.m/s
Explanation:
Given
mass, m = 5 kg
speed, v = 3 m/s
momentum, p = ?
We know that the momentum is given by the equation:
p = mv
= 5 kg x 3 m/s
= 15 kg.m/s
Two ways that strong nuclear and weak nuclear forces are alike: Strong nuclear and weak nuclear their alike because they deal with atoms and subatomic particles. ... Two ways that electromagnetic force and gravity are alike: Electromagnetic force and gravity are alike because both of them has an infinity force.
Answer:
net power is + 2.25 D
Explanation:
Given data
distance vision = -0.25 D
near vision = + 2.50 D
to find out
net power
solution
we have given a person lens power for near is - 0.25 diopter and lens power for near power is +2.50 diopter so
net power is sum of both the power vision
so
net power = distance + near power
put both value we get net power
net power = ( -0.25 D) + ( + 2.50 D)
net power = + 2.25 D
so net power is + 2.25 D
