Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.
Answer: D) It should be handled in a fume hood, away from open flames.
Answer:
- 2.7 x 10^-6 J
Explanation:
q1 = 1 nC at x = 0 cm
q2 = - 1 nC at x = 1 cm
q3 = 4 nC at x = 2 cm
The formula for the potential energy between the two charges is given by

where r be the distance between the two charges
By use of superposition principle, the total energy of the system is given by



U = - 2.7 x 10^-6 J
Answer:
What is the kinetic energy of a bicycle with a mass of 14 kg traveling at a velocity of 3 m/s? Physics ... K=12mv2=12×14 kg × (3 m/s)2=63 Joule.
1 answer

Explanation:
K=12mv2=12×14 kg × (3 m/s)2=63 Joule.
63 Joule Explanation: K=12mv2=12×14 kg × (3 m/s)2=63 Joule
Answer:
b) 4781 N
Explanation:
Because there is a redius do this question is talking about the acceleration force which= mv^2/r
so a=15^2/80=2.8125 m^2/s
so the force will be = m.a
F =1700×2.8125=4781.25 N
