Answer:
It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
Explanation:
Conduction phenomenon of charging is the process of charging in which two bodies are made in contact with each other so that charges are transferred due to potential difference of two bodies.
here we know that when hands are shake then it will have paint on it. so here due to hand shake the hands are in contact with charge particles and due to contact the electrons are transferred to the hand.
Now here we need to assume that charge of paint must be opposite that of the charge on the hand because only due to opposite charge attraction the paint must be transferred to the hand
SO here correct answer will be
It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
The object is turnigng loosing kinetic energy then it will eventually go strate and game monetize energy
Answer: work of 17.52 J is done
Explanation:
Given that;
Force F = 12 N
distance d = 1.46 m
work W = ?
we know that work done is force F multiple by distance d
so Work W = force F × distance d
we substitute our values
Work done W = 12 × 1.46
W = 17.52 J
Therefore a work of 17.52 J is done
Answer:
Two types of energy include potential and kinetic energy, which causes motion, which in turn is caused by a force.
Answer:
Microwave takes 13.67μs to travel from cell phone to tower
Explanation:
Given data:
Distance traveled by microwave from cell phone to tower =
We know that the microwave is an electromagnetic wave and the velocity v of electromagnetic wave is 3 x m/s.
In general, to determine time of travel from distance and velocity given, we divide distance traveled by velocity. That is
Velocity =
Hence, time =
Therefore, time of travel of microwave =
=
= 13.67 x s
= 13.67 μs (μs is microseconds)
Hence microwave takes 13.67μs to travel from cell phone to tower.
