Answer:

Explanation:
Given that,
The mass of the Jupiter,
The radius of Jupiter,
We need to find the acceleration due to gravity on Jupiter. The formula is

Put all the values,

So, the value of acceleration due to gravity on the Jupiter is
.
This is called refraction. Some common examples of refraction are a straw appearing bent or cut once it enters water in a glass.
Answer:29 electrons
Explanation: If you look on a periodic table, the atomic number is the amount of electrons it has.
Answer:
DU = 21 KJ
Explanation:
Given the following data;
Quantity of heat = 125 KJ
Work = 104 KJ
To find the change in internal energy;
Mathematically, the change in internal energy of a system is given by the formula;
DU = Q - W
Where;
DU is the change in internal energy.
Q is the quantity of energy.
W is the work done.
Substituting into the formula, we have;
DU = 125 - 104
DU = 21 KJ
Answer:

Explanation:
The rotational kinetic energy when the cylinder is with the rope is:

where we used the fact that both rope and cylinder hast the same w. This E_k must conserve, that is, E_k must equal E_k when the rope leaves the cylinder. Hence, the final w is given by:
(1)
For Ic and Ir we can assume that the rope is a ring of the same radius of the cylinder. Then, we have:

Finally, by replacing in (1):
