Question -
The force that opposes the motion of objects that touch as they move past each other is called.....
Answer -
The force that opposes the movement of an object through water is called drag. This is a type of frictional force. This force normally depends on the density and the viscosity of the fluid in question. The liquid which has more density and more viscosity or stickiness will produce a greater amount of drag force on an object than a fluid that is less dense and less viscous in nature. River water normally has less drag than that of sea water.
Hope i helped. have a wonderful day....can i get brainliest please and thank you....
The red giant star would turn into a red dwarf.
180+156=336
4+3=7
336/7=48mph
Answer:
Explanation:
A charge Q will create an electric field in the space surrounding it. The strength of an electric field, E in a location in space can be determined by placing a test charge, q in the space and measuring the force (F) which is exerted upon it. The electric field strength is then defined as the amount of force per unit of charge on the test charge.
E = F/q
The electric force, F depends upon the following as described by Coulomb's law:
F = kQq/d2
Here, Q might be the source charge and q might be the test charge. Therefore,
E = k × Q/d2
