Answer:
F = 29.9 N
Explanation:
It is given that, The Sun exerts a gravitational force of 29.9 N on a rock that's located in a river bed here on Earth. We need to find the gravitational force the rock exert on the Sun. It is a case of Newton's third law of motion which states that the force acting from one object to another is equal to the force acing from second object to the first object and the two forces must be in opposite direction. Hence, the gravitational force the rock exert on the Sun is same i.e. 29.9 N.
Answer:
speed of the spaceship is 0.495251 c
Time T = 1.4982 hr
Explanation:
given data
length L1 = 1600 m
length L2 = 1390 m
to find out
speed of the spaceship and time
solution
we know here
L2 = L1 × 
so we find V by put L1 and L2
1390 = 1600 × 
V = 0.495251 c
speed of the spaceship is 0.495251 c
and
we know T1 = 1.95 hr
so we find T2
T1 = T2 
put here V and T1 so we get T2
1.95 = T2 
Time T = 1.4982 hr
The real world examples that I can give is the everyday
things that we do and some of these are:
I am walking to the end of the room holding three textbooks.
Playing tug of war with friends.
Getting the groceries from the car and put it inside of your house.
Answer:
when it interacts with other electrons without changing its speed
Explanation:
without changing its speed
No it does not because this weight is being balanced by a normal source
