Answer:
In physics, a polar vector is a vector such as the radius vector that reverses sign when the coordinate axes are reversed
Explanation:
Polar vectors are the type of vector usually simply known as "vectors." In contrast, pseudovectors (also called axial vectors) do not reverse sign when the coordinate axes are reversed.
The centripetal force experienced by the towel is 55 N.
The given parameters;
- angular speed of the washing machine, ω = 200 rpm
- radius of the machine' drum, r = 0.5 m
- mass of the towel, m = 0.25 kg
The centripetal force experienced by the towel spinning along the walls of the drum is calculated as follows;
Fc = mrω²
where;
<em>Fc is the centripetal force</em>
<em>ω is angular speed in rad/s</em>
The angular speed in rad/s is calculate as;

The centripetal force experienced by the towel is calculated as;

Thus, the centripetal force experienced by the towel is 55 N.

This is your answer
Explanation:
Actually I took this from go ogle
Explanation:
Formula for the electric field due to the infinite sheet of charge is as follows.
E =
where,
= surface charge density
Now, formula for electric force acting on the proton is as follows.
F = eE
where, e = charge of the proton
According to the Newton's second law of motion, the net force acting on the proton is as follows.
F = ma
a = 
= 
= 
According to the kinematic equation, speed of the proton in perpendicular direction is as follows.

= 
= 
= 683.974 m/s
Hence, total speed of the proton is as follows.
v' =
= 
= 
= 1178.73 m/s
Therefore, we can conclude that speed of the proton is 1178.73 m/s.
Gravitational forces between two objects decrease as the objects
get farther apart.
That's a big part of the reason why the Earth attracts us with more
force than Jupiter does.
