Answer:
The red ball has a greater kinetic energy, because it has a greater mass
Explanation:
Mass is directly proportional to kinetic energy, as one increases, so does the other
A. The molecules start packed together very tightly in a solid. Then when it turns to water, the molecules can move around each other freely, but still contained. When water turns to vapor, the molecules are going crazy moving around. They are not contained at all and bounce of of each other freely.
b. The temperature rises. (ice turns to water at 33 degrees and water turns to vapor at 212 degrees)
The value of the thrust developed by the engine of a boeing 777 in N and Kgf are ;
i) 376616N
ii) 38430Kgf
<h3>What is force?</h3>
Force is a push or a pull. The reactive force always serve to balance the applied force. We are here asked to convert the the thrust developed by the engine of a boeing 777 which is about 85400 lbf to the following units;
i) N
ii)kgf
Thus;
1 Ib = 0.45 Kg
1 lbf = 0.45 Kg * 9.8 m/s^2 = 4.41 N
We know that;
1 lbf = 4.41 N
85400 lbf = 85400 lbf. * 4.41 N/1 lbf
= 376616N
Again;
1 lbf = 0.45 Kgf
85400 lbf = 85400 lbf * 0.45 Kgf/1 lbf
= 38430Kgf

K.E = 1/2mv^2
The kinetic energy is 50,000 J and the mass of the car is 10,000 kg.
50,000 J = 1/2(10,000kg)v^2
Solve for v (velocity)
50,000 J = 5,000 kg x v^2
10 = v^2
about 3 m/s (in terms of significant figures)
Speed = wavelength x frequency determine the speed of a wave,
