A 4.3 kg bowling ball is initially at rest. If a 15 N force acts on it for 0.85 s, what is the final velocity of the bowling ball?

According to Newton's 2nd law of motion, F = ma ==> a = F / m =15/4.3 = 3.48 m/s^2. Now using kinematic equation, v=u+at => v= 0 + 3.48x0.85 => V= 2.958 m/s

Explain Why must a cooling system do work to transfer thermal energy?

Although internal energy will not spontaneously flow from a cold region to a hot region, it can be forced to do so by doing work on the system.Refrigerators and heat pumps are examples of heat engines which cause energy to be transferred from a cold area to a hot area. Usually this is done with the aid of a phase change, i.e., a refrigerant liquid is forced to evaporate and extract energy from the cold area. Then it is compressed and forced to condense in the hot area, dumping its heat of vaporization into the hot area. ARE YOU FROM K12?

Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy

When we say potential energy, this is the energy at rest. And kinetic energy is the energy at motion. So, here are the examples of energy that is transforming from potential energy to kinetic energy: changing thermal energy to electrical energy, and changing radiant energy to electrical energy. Hope this answer helps.

If two carts collide, what type of collision will conserve both momentum and kinetic energy? a. head on b. perfectly inelastic c. none d. perfectly elastic

The appropriate answer is d. perfectly elastic. When a perfectly elastic collision occurs both momentum and kinetic energy are preserved. Momentum is the mass of an object times its velocity while kinetic energy is the energy that a moving object has due to its motion. In an elastic collision kinetic energy would be converted to some other form of energy.

Which makes fast-moving water a greater force of erosion? A. greater heat capacity B. greater energy C. increased density D. greater oxidation

Answer:

B. Greater energy

Explanation:

Fast moving water is very energetic as its can displace very large rocks, boulders and make pebbles and sand out of them through the process r erosion. Fast moving water have kinetic energy, it opposes anything that come in its way. As river make its own channel by eroding plane. Many antecedent rivers have make their channel by cutting large mountains too.

A football is kicked into the air from an initial height of 4 feet. The height, in feet, of the football above the ground is given by s (t)=-16^2+50t+4, where t is time, in seconds, and t>=0. At what time will the football be 25 feet above the ground? 3.625 seconds 3.20 seconds 0.5 seconds or 3.625 seconds 0.5 seconds or 2.625 seconds

Answer: 0.5 seconds or 2.625 seconds

Explanation:

At t = 0, The ball is 4 ft above the ground.

The height of the football varies with time in the following way:

s(t) = -16 t² + 50 t + 4

we need to find the time in which the height would of the football would be 25 ft:

⇒25 = -16 t² + 50 t + 4

we need to solve the quadratic equation:

⇒ 16 t² - 50 t + 21 = 0

t = \frac{50 \pm \sqrt{50^2-4\times 16\times 21}}{2\times16}

⇒ t = 0.5 s or 2.625 s

Therefore, at t = 0.5 s or 2.625 s, the football would be 25 ft above the ground.

I need help with forms of energy.

Electrical Energy

A bolt of lightening is electrical energy. This is the same kind energy used by an electrical outlet. Electrical energy travels through power lines and then helps make lots of different machines work.

Motion Energy:
Moving things have energy. The faster something is moving, the more energy it has. Pose this question to your students: Which do you think has more motion energy, a book that is falling off a table or a truck driving down the road at 60 miles per hour? You can explain that the truck has more motion energy because it is traveling much faster than a book. Another reason why the truck has more motion energy is that the truck is much heavier than the book.

Why aren't renewable resources used for everything that we use energy for?

With options like coal and fossil fuels being much more effective, natural greed keeps companies from using things that are renewable because using something that is renewable takes time but burning off non-renewables is easy and fast

Posted in Physics

What does it mean that a form of energy might take more energy to harness than it provides? Are renewable resources always renewable, or can they become non-renewable? Why aren't renewable resources used for everything that we use energy for? Explain.

A form of energy might take more energy to harness than it provides because of dissipated energy. During the transformation process, not all of the energy will be converted to useful energy. Some of the energy are dissipated in the form of heat. Renewable resources are resources that are replenished at a faster rate than they are used. They become non-renewable when these resources are used up at a faster rate than they are replenished. We don't use renewable resources for everything that we use energy for because the energy transformation might be inefficient or requires a lot of capital and maintenance.

Why is a train more difficult to stop then a rolling ball even if they are traveling at the same speed? URGENT

Think of the formula force=mass x acceleration. even though they have the same acceleration, a train has more mass. is that helpful?

Posted in Physics

What it means to say that energy is conserved as a ball fall towards ground

Mechanical energy = Potential Energy + Kinetic Energy

if there is no friction, M.E. is conserved
as a ball falls, it is losing height. (P.E.=mgh , therefore P.E. will decrease)

the potential energy is transformed into kinetic energy which equals 1/2MV^2.

the increase in K.E. equals the decrease in P.E.

and the sum of both equals M.E.

thus mechanical energy is conserved.

hope this helps you.
