The answer is D
This is an example of Newton's third law of motion.
The active force is the fish against the water, so the reactive force would be the reverse, the equal force of the water on the fish.
Answer:
7532m
Explanation:
Gravity on the surface of the earth with radius R is given by:
Gravity a distance r above the surface:
How big is r if:
You get the following equation:
Solve for r:
Answer:
3000 N
Explanation:
We have,
• Mass, m = 1000 kg
• Acceleration, a = 3 m/s²
We have to find force required, F.
F = ma
F = 1000 × 3 N
F = 3000 N (Answer)
Because it has both magnitude and direction. When an object has positive acceleration, the acceleration occurs in the same direction as the movement of the object.
Answer:
3272.4 Hz
Explanation:
L = 31 mH
XL = 637 ohm
XL = 2 π f L
f = XL / (2 π L)
f = 637 / ( 2 x 3.14 x 31 x 10^-3)
f = 3272.4 Hz
