1. On a force vs. mass graph, what would be the slope of the line?
Luden [163]

1. By Newton's second law,

<em>F</em> = <em>m</em> <em>a</em>

so the slope of the line would represent the mass of the object.

2. If all the forces are balanced, then the object is in equilibrium with zero net force, which in turn means the object is not accelerating. So the object is either motionless or moving at a constant speed.

A student lefts a bouncy ball to 1.2m, then releases the ball. The ball bounces back up to 0.86m. Construct an explanation as to
Airida [17]

Answer:

the decrease in energy is due to a transformational in internal energy of the body in the rebound.

Explanation:

For this exercise we can calculate the initial and final mechanical energy

        Em₀ = U = m g y₁

        Em_{f} = U = m g y₂

we look for the variation of the energy

       ΔEm = Em_{f} - Em₀

       ΔEm = m g (y_{f} -y₀)

       ΔEm = m g (0.86 -1.2)

       ΔEm = -3.332 m

We can see that there is a decrease in mechanical energy, this is transformed into internal energy of the ball during the impact with the ground, this energy can be formed by several factors such as a part of the friction with the surface, an increase in body temperature or a deformation of the body; there may be a contribution from several of these factors.

In conclusion the decrease in energy is due to a transformational in internal energy of the body in the rebound.

murzikaleks [220]

Answer:

B

Explanation:

F=\frac{Gm1m2}{r^2}

F=(6.67 x 10^-11)\frac{63.7X9,750.6}{7.5^2}

The brain is responsible for storing memories. How is this helpful for helping the body react to stimuli?
tatuchka [14]

Answer:

The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of, like the beating of your heart and the digestion of your food.  Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
