Answer:
Acceleration due to gravity on Mars = 3.72 m/s²
Explanation:
It is given that the grandfather clock on Mars lags 23 minutes behind the grandfather clock on Earth after 1 hour.
Mars = 60 - 23 = 37 minutes
So the time on Mars is 37 minutes when time on Earth is 60 minutes.
We know that time period on Earth is given by
Te = 2π√(L/ge)
Where ge is acceleration due to gravity on the Earth
We know that time period on Mars is given by
Tm = 2π√(L/gm)
Where gm is acceleration due to gravity on the Mars
So,
Te/Tm = 37/60 = 0.616
0.616 = 2π√(L/ge)/2π√(L/gm)
Simplifying the above equation yields
0.616 = √gm/√ge
√gm = √ge*0.616
squaring on both sides
gm = ge*0.616²
The acceleration on the Earth is 9.81 m/s²
gm = 9.81*0.616²
gm = 3.72 m/s²
Therefore, the acceleration due to gravity on Mars is 3.72 m/s².
Answer:
(1) Exercise should be painful in order for it to be beneficial. FALSE
(2) Proper progression involves a gradual increase in the level of exercise. TRUE
(3) Exercising on a regular, consistent basis provides you with the best results. TRUE
Explanation:
(1) It is a false statement because whenever we do exercise, it should not be painful, it should be comfortable to some extent for a person, if it will be painful then it means one cant get the true and genuine benefit from the exercise.
(2) It is very much true because one must keep on increasing the level of his/her exercise gradually with the passage of time, it will make his/her body synchronized with the exercise properly.
(3) It is also a true statement because, one must use variety of exercises in his/her workout session targeting different muscles and different areas and parts of the body to make exercise really beneficial.
The answer to this question is:
Simply it can be calculate using the equation Q=It, here Q is the charge in coulombs , I current in Amps and t is the time in seconds.
so the answer is Q = 10*60 = 600 coulomb.
I believe it is A bit not completely sure
Distance= Time×Speed
= 1800×1.5
= 2700 m
I am not sure it's right. the question itself is confusing.
