Which makes fast-moving water a greater force of erosion? A. greater heat capacity B. greater energy C. increased density D. greater oxidation
B. Greater energy
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.
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
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.
The stress force that causes a mass of rock to pull or twist in opposite directions is called shearing.
Hope this helps! :)
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
delta t=37.5 °C
I hope my answer has come to your help. God bless and have a nice day ahead!
SIZE AND DISTANCE BETWEEN THEM
F = 49N
I Took The Test!
here, F = 25 N
s = 3 m
Substitute it into the expression,
W = 25 * 3
W = 75 Joule
So, your final answer is 75 J
Hope this helps!
The acceleration of an object can be calculated by using Newton's second law:
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:
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
Two wagons of equal mass are filled with an equal mass of bricks. Person A pushes one wagon with twice the force that Person B pushes the second wagon. How is the acceleration affected? A. Person A's wagon will accelerate at twice the rate of Person B"s wagon. B. Person A's wagon will accelerate at 1/2 the rate of Person B's wagon. C. Both wagons will accelerate at the same rate, since the mass is the same.
Force times Mass equals Acceleration.
The answer is TRUE.
If the mass increases the number on the left side of the equation increases, thus increasing the right side as well.
Which statement is NOT true? a. water plays an important role in the control of body temperature b. water helps carry nutrients to cells and waste products away from cells c. people need a minimum of 10-12 glasses of water each day d. soups, fruits, vegetables, and meats are sources of water
There are two ways the Scientific and the Normal.( for a lack of better word)
Normal: The heat escapes into space.
Scientific: As the molecules of the element heat up and vibrate for long periods they lose heat so they return to their original temperature (at least try to)
hope this helps you
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.
The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecule and thermal energy is the total kinetic energy of all particles in a given substance.
