Insulators do not allow electrons to move easily through them.
Answer:
Correct answer: V₂ = 1.79 m/s
Explanation:
Given:
m₁ = 32 kg the mass of the first student
V₁ = 2.4 m/s speed of the first student after pushing
m₂ = 43 kg the mass of the second student student
V₂ = ? speed of the second student after pushing
I₁ = m₁ · V₁ impulse of the first student
I₂ = m₂ · V₂ impulse of the second student
Under the law of impulse maintenance, the total impulse of an object must be constant over time.
Since the total impulse before pushing was equal to zero it must be afterwards.
I₁ + I₂ = 0 ⇒ I₂ = - I₁ ⇒ V₂ = - V₁
Given that the impulses are vectors a sign minus ahead of the first pulse mean, they are opposite directions.
m₂ · V₂ = m₁ · V₁ ⇒ V₂ = (m₁ · V₁) / m₂ = (32 · 2.4) / 43 = 1.79 m/s
V₂ = 1.79 m/s

A She can run the same distance in a shorter amount of time.
Explanation:
Speed is a physical quantity that expresses the rate of change of distance with time:
Speed =
We can see that speed will increase if the distance covered increases with a decreasing amount of time.
Speed will decrease if the distance decreases with increasing time
Speed will increase if the distance covered stays the same with decreasing time
Speed will reduce if the distance covered stays the same with increasing time.

Answer: 218,240,000 fathom.
Explanation:
Given : A fathom is a unit of length, usually reserved for measuring the depth of water.
A fathom is approximately 6 ft in length.
The distance from Earth to the Moon to be 248,000 miles.
Since, 1 mile =5280 feet
Then, the distance from Earth to the Moon =
The distance from Earth to the Moon in fathoms :
Hence, the the distance in fathoms 218,240,000 fathom.
