Answer:
protons
Explanation:
the protons identifies an atoms as that of a particular element the atomic number is equal to the number of protons in the nucleus of an atom
If you let a friend ride with you, increasing the mass does increase the net force on the system, but it also increases the inertia. a=Fnetm. Since both the net force and mass are increased they still cancel, leaving the acceleration the same.
<h3>Further explanation
</h3>
Inertia is the tendancy of a moving object to keep moving in a straight line or of any object to resist a change in motion.
According to the picture below, we choose x-direction parallel to the inclined surface. Our positive direction is to the right. Hence, we will calculate the acceleration when riding solo first:
Put 
into 
From the equation 3, we found that the acceleration does not depend on the mass of the object. Notice that:
is constant
is constant,
is constant
So that, 
is constant whatever the amount of the mass is

Explanation:
64-kg skater initially at rest throws a 4.0-kg medicine ball horizontally to the left. Suppose the ball is accelerated through a distance of 1.0 mm before leaving the skater's hand at a speed of 7.0 m/s. Assume the skater and the ball to be point-like and the surface to be frictionless and ignore air resistance. Use a vertical y-axis with the positive direction pointing up and a horizontal x-axis with the positive direction pointing to the right.
Required:
a. Determine the acceleration of the ball during the throw.
b. Determine the acceleration of the skater during the throw.
Force- An interaction between an object that causes it to change it's velocity.
Energy- Ability to do work. It also comes in different forms including Thermal heat, Radiant Light, and Kinetic Motion.
Answer:
Sunspots, flares, prominences, and coronal mass ejections are all caused by magnetic activity on the Sun.
