Answer:
Explanation:
F=ma
F in this case is the gravity acting on the 2kg object. Acceleration of gravity is 9.8 m/s^2. SF=ma, so
F = 2kg*(9.8 m/s^2) = 19.6 N
Now use this force to determine the mass of the object on the table:
F=ma
19.6 N (1N=kg*m/s^2) = m*(1.8 m/s^2)
m = 10.89 kg
Answer:
Soory
Explanation:
I really dont know but i will send you wait
The person walking down the sidewalk follows the newton's third law of motion.
Explanation:
- A person is able to walk down the sidewalk by using the reaction forces from the ground.
- In simple term, feet pushes the ground and the reaction forces makes the feet able to walk.
- Another important force included in the walking mechanism is friction. With out friction one cannot walk down the sidewalks.
- Hence the forces involved in the walking of a person down the sidewalk are:
- Friction force
- Action and reaction force between ground and person's feet.
Possibly by the damage done compared to the previous ones.
D.Both B and C
As they not allow heat to pass through and usually non metal
