Answer:Electrons have negative charge.
Explanation:Electrons are designated to be the carriers of negative charge. The assignment of negative and positive to electrons and protons respectively can be attributed to Benjamin Franklin. He could have easily reversed this designation. Like all charged particles, negative charges create electric fields around them.
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
D. Number of cycles/ unit of time
<h2>RED!</h2><h3></h3><h3>On the visible spectrum, red has the lowest frequency.</h3><h3>(I'm an amateur astronomer, so I would know.)</h3>
Answer:
Explanation:
In order to find the acceleration of the block, we have to find the net force acting on it along the direction parallel to the incline.
However, there is only one force acting on the block along this direction: it is the component of the weight parallel to the plane, given by
where
m = 15 kg is the mass of the block
is the acceleration of gravity
is the angle of the incline
According to Newton's second law, the net force is proportional to the acceleration, a:
So we can write:
And so, the acceleration is:
