Answer:
Friction stops things from sliding apart. If there was no friction everything would slide to the lowest point. It would be impossible to climb up anything. Imagine trying to climb a wall of ice without crampons and an ice pick. It would be impossible.
From the human perspective, it would be impossible to stand up or even move. Simply crawling requires a force to make you move. That is provided by friction.
With no friction, the only possible movement would be falling to a lower point under gravity.
Explanation:
In physics, gravity is the natural force that causes things to fall toward the earth. The noun gravity can also mean seriousness or solemnity. Someone who conducts themselves with an air of gravity is someone who takes what they are doing seriously.
250 kg*m/s
Momentum is found by multiplying mass by velocity
25*10=250
Answer:
Explanation:
The magnetic field strength is given by:
where
is the vacuum permeability
I is the current
r is the distance from the wire
In this problem,
I = 6.5 A
r = 6.3 cm = 0.063 m
So, the magnetic field strength is
