Answer:
F = 98 N
Explanation:
Data:
- Mass (m) = 14 kg
- Acceleration (a) = 7 m/s²
- Force (F) = ?
Use formula:
Replace:
Multiply both operations, with the units:
What is the amount of the force?
The amount of the force is <u>98 Newtons.</u>
Answer:
1.47kW
Explanation:
F = 300N, s = 50m, v = 5.9m/s
P = W/t
= (F× )/t
= F × v
= 300 × 5.9
= 1470Watt
= 1.47kW
Answer:
The radius of a chamber is 2.36 meters.
Explanation:
Given that,
The outer wall moves at a speed of 2.72 m/s.
Mass of the person, m = 75.1 kg
The person feels a force of 235 N force pressing against his back. The force acting on the person is centripetal force. It is given by the below formula :

r is the radius of a chamber


r = 2.36 meters
So, the radius of a chamber is 2.36 meters. Hence, this is the required solution.
Answer:
D (Not too sure)
Explanation:
Natural selection favors the species that can work the best in the environment.
Answer:
New force = 9(initial force)
Explanation:
The force between two charges is given by :

Where
d is the original distance
Let d' is the new distance such that, r' = r/3
New force,

So, the new force becomes 9 times the initial force.
