Each time a uranium nucleus splits<span> up it releases energy and three neutrons. If all the neutrons are allowed to be absorbed by other uranium nuclei the chain reaction will spiral out of control causing an explosion. To control the energy released in the reactor moveable control rods are placed between the fuel rods.</span>

Since the moon has less mass then the earth what happens to objects on the moon
marshall27 [118]

A) They move slower


Gravity force is determined by mass and the size of the moon. Since the mass of the moon is significantly lower than the mass of Earth, it will pull objects slower. The only object that would fall faster on the moon than on earth is a sheet of paper since there is much, much less air resistance to affect its terminal velocity the way it does on the earth.

One ounce of a well-known breakfast cereal contains 104 Calories (1 food Calorie = 4186 J). If 2.5% of this energy could be conv
GalinKa [24]

Answer:

482.4 kg

Explanation:

104 calorie = 435344  J

The 2.5% of this energy equals to

435344  * 0.0025 = 10883.6 J

If this energy is converted to work done on lifting a barbell by a distance of 2.3. By the formula of Work W = force * distance then the force he exerts on the barbell is

F = \frac{W}{D} = \frac{10883.6&#10;}{2.3} = 4732  N

Assuming gravitational constant g = 9.81 m/s2 then the mass of the barbell is

m = 4732  / 9.81 = 482.4 kg

If the object starts at point A what is the total energy of the system?
Oxana [17]

The total energy of the system is 88.2 J

Explanation:

The total (mechanical) energy of an object is given by:

E=PE+KE

where

PE is the potential energy

KE is the kinetic energy

At the starting point, the object is at rest: this means that its kinetic energy is zero, so all its energy is potential energy, which is given by

PE=mgh

where

m is the mass of the object

g is the acceleration of gravity

h is the height of the object

In this problem, we have (at point A):

m = 3.0 kg

g=9.8 m/s^2

h = 3.0 m

Substituting, we find:

E=U=(3.0)(9.8)(3.0)=88.2 J
