Because oil is a lubricant which reduces friction between our hands and glass. Less friction and it tends to slip so yes , it is related to friction
The "pitch" of a sound is the impression your brain forms
that corresponds to the frequency of the sound wave.
When the frequency is high, your brain says "high pitch".
When the frequency is low, your brain says "low pitch".
I think it is electron. Electrons are located outside of the nucleus
Answer:
F=-100N; a=1.3m/s^2
Explanation:
Force is being made by student, so wall counteracts that force by not moving so it is equally opposite.
Answer:
Number of turns,
Explanation:
Given that,
The maximum strength of the Earth's magnetic field,
This field could be used with a rotating coil to generate 60.0-Hz ac electricity.
Let us assume that the coil must have to produce an rms voltage of 120 V and area per turn is 0.022 meter square.
The emf induced in the coil is given by :
N is the number of turns
f is the frequency
or
So, there are turns in the coil.
