Answer:
A box sits stationary on a ramp
Explanation:
Static friction is a force which keeps an object at rest as it is in the case of the box. It has to be overcome for the object to be set into motion.
Static force of friction is calculated as follows:
F= μη
F is static force of friction.
μ is the coefficient of static friction.
η is the normal force.
(1,500 meters) x (1 sec/330 meters) =
(1,500 / 330) (meters-sec/meters) =
4.55 seconds
Answer:
A non-contact force is a force which acts on an object without coming physically in contact with it.
Explanation:
For example:
<em>Gravitational force.</em>
<em>Magnetic force.</em>
<em>Electrostatics.</em>
<em>Nuclear force.</em>
You can use a spring scale, however, if you have all the information needed for the formula, it is best to use it as it offers a more precise answer.
