The answer is 80 m.
Centripetal force (F) is a force that makes body move around a circular curve. The unit of force is N (N = kg * m/s²).
It can be represented as:

where:
m - mass
v - velocity
r - radius of the curve
We have:
m = 1,200 kg
V = 20 m/s
F = 6,000 N = 6,000 kg * m/s²
We need radius of the curve:
r = ?

Answer:
50W
Explanation:
The formula and is
W = F × s
(force x distance)
W= 50 N× 5 m =250 N m=250 J
Done in 5 seconds the power is
p
=
W
t
where
t
=time
p
=
250
J

=
50 J
/s
=50 W
Mass is how much matter is in an object. Volume is how much space an object occupies. Density is the amount of mass in a volume.
Have a nice day, brainliest would be fantastic
It is OH- (hydroxide ion)
D, because matter does not change in space but unlike gravity, which changes, matter, is the mass of it, which will stay the same unless there is a chemical change or, physical change, but not in this case, so the answer you are looking for is D. hope this enlarged your understanding and knowledge.
