Answer:
Explanation:
The normal force exerted on the car by the walls of the cylinder at the bottom of the vertical circle will be such that when substracted to the weight it must give the centripetal force, since at that point on the vertical
We also know that the equation for the centripetal force is:
Mixing both equations we get:
Which for our values means:
Answer:
The kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.

The diagram below shows the heating of an unknown substance (it is not water). Its melting point is? Where is the diagram
The force between two charged particles is an electrostatic force. The intensity of this force is given by the following formula:
Where q1 and q2 are charges r is the distance, and k_c is Coulomb's constant.
Coulomb's constant has the value of:
When we plug all the given values into the formula we get:
Negative sign means that force is attractive.
