I believe the best answer is law, as scientific laws are accepted to be true under the proper conditions.
Answer:
15 watt
Explanation:
Power is the rate at which work is done.
This means you divide the work done with the amount of time used to perform the work.
The formula for Power is : P = W/t where;
W= work done in J = 45
t= time in seconds = 3 sec
P= 45/ 3 = 15 watt
Answer:
This is because these metals are used for minting (making) coins.
The volume of the object must be no larger than
.
Explanation:
In order for an object to be able to float in water, its density must be equal or smaller than the water density.
The density of water is:

This means that the density of the object must be no larger than this value.
We also know that the density of an object is given by

where
m is the mass of the object
V is its volume
For the object in this problem, the mass is

Therefore, we can re-arrange the equation to find its volume:

So, the volume of the object must be no larger than
.
