Answer:
The expected year is 2017.
Explanation:
Total years that the millionaire to live = 15 years
Travel away from the earth at = 0.8 c
This is a time dilation problem so if she travels at 0.8 c then her time will pass at slower. Below is the following calculation:
Thus the doctors are expecting to celebrate in the year, 1992 + 25 = 2017
Answer:
If the force applied is larger than 185.2 N, yes.
Explanation:
In order to move the table, the pushing force must be larger than the frictional force. The frictional force is given by:
where
is the coefficient of static friction
is the mass of the table
is the gravitational acceleration
Substituting,
So, we are able to move the table if we push with a force larger than 185.2 N.
