Answer:
The answer will be 936 N.
Explanation:
Given that
m = 80 kg
Acceleration of the elevator , a= 1.7 m/s² ( upward)
The gravity force on the mass = m g
The reading on the scale = F N
Now by applying the Newton's second law
F - m g = ma
F= m g + m a
F= m ( g +a )
F= 80 ( 10 + 1.7 ) N ( take g= 10 m/s²)
F=80 x 11.7 N
F= 936 N
Therefore the reading on the scale will be 936 N.
The answer will be 936 N.
Answer:yes
Explanation:The constan acceleration means that it wont stop moving but if you kick it a different direction then it will change direction
The period of a pendulum is given by

where L is the pendulum length and g is the gravitational acceleration.
We can write down the ratio between the period of the pendulum on the Moon and on Earth by using this formula, and we find:

where the labels m and e refer to "Moon" and "Earth".
Since the gravitational acceleration on Earth is

while on the Moon is

, the ratio between the period on the Moon and on Earth is
