DescriptionElectric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative. Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral.
Answer:
D is the correct answer! Hope this helps you!!!!
Explanation:
Hi there!
22.
We can calculate the speed by first calculating the period of the stopper.
1 period = time taken for one revolution
10 rev/10 sec = 1 rev/sec
Since it takes 1 second for the stopper to make a complete circle, its velocity can be found using the equation for circumference:

The centripetal force can be solved for using the following:
m = mass (kg)
v = velocity (m/s)
r = radius (m)
Fc = Centripetal force (N)
Plug in the givens:
Objects repel and attract because of a thing called electrostatic attraction. When objects have the same charge (positive or negative), then they will repel, and if they have opposite charges then they will attract
Answer:
I think its a fuse because everything else makes sense and is used in electrical circuits and the fuse is the only one that stands out to me ¯\_(ツ)_/¯
