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. ## Related Questions Posted in Physics Which of the following is not an example of kinetic energy? mechanical energy nuclear energy electrical energy thermal energy It is only mechanical energy that is kinetic energy while the other choices are not kinetic energy. Nuclear, electrical and thermal are other types of energy. Hope this answers the question. Have a nice day. Feel free to ask more questions. Posted in Physics How would the acceleration of a chain of three shopping carts compare with the acceleration of a single cart if the same force acted on both? A. 1/3 as much the single B. 1/2 as much the single C. 3 times as much the single D. 2 times as much the single So in order to know the correct answer, let us analyze the problem. Given that a = F/m where a is acceleration, F is force and m is mass, here is the solution. a = F/m a' = F/3m a'/a = 1/3 Based on this, the correct answer would be option A. 1/3 as much the single Hope this helps.

If a 375 mL sample of water was cooled from 37.5 C to 0 C how much heat was lost in joules?

Please, you have to apply the formula below:

Q=c∗m∗Δt

where Q is the energy lost,

c is the specific heat of water,

m is the mass of water involved,

so m=3.75 *10^-1 Kg

c=4,184 J/(Kg*°C)

delta t=37.5 °C

I hope my answer has come to your help. God bless and have a nice day ahead!

We Know, W = F * s
here, F = 25 N
s = 3 m

Substitute it into the expression,
W = 25 * 3
W = 75 Joule

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

Answer: Explanation: The acceleration of an object can be calculated by using Newton's second law: where F is the net force applied on the object m is the mass of the object a is its acceleration In this problem, we have F=125 N and m=25.0 kg, so we can rearrange the equation to calculate the acceleration: Posted in Physics 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?

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.

A 521-kg meteor is subject to a force of 2520 N. What is its acceleration?

Acceleration,

Explanation:

It is given that,

Mass of the meteor, m = 521 kg

Force acting on the meteor, F = 2520 N

Let a is the acceleration of the meteor. It can be calculated using the Newton's second law of motion. According to this law the force acting on an object is equal to the product of mass and acceleration with which it is moving. Mathematically, it is given by :

So, the acceleration of the meteor is . Hence, this is the required solution.
