Answer:
10 kg
Explanation:
The mass of an object does not change even if the amount of gravtiy changes.
We're so good here on Brainly, we can answer it
even WITHOUT seeing the choices.
Time = (displacement) / (magnitude of average velocity) .
11.Perfectly elastic,as in only this collision K.E is conserved,however momentum is conserved in both elastic and inelastic collisions.
9)must also be conserved.because there is eleastic collision.
8)unchanged.
7)dcreases as velocity changes from 0.5 to 0 m/s.
4)momentum
Answer:
149.8Hz
Explanation:
V=I.(XL).........{1}
where (XL) is inductive reactance
(XL) =2πfL......... {2}
V= 41.5, l= 4.5, L= 9.8* 10^-³
take π to be 3.14
(XL) = V/I
= 41.5/4.5
= 9.22
f = (XL) /2πL
= 9.22* 10^³/6.28* 9.8
=149.8
Answer:
100 N
Explanation:
Given that,
Two forces whose resultant is 100newton are perpendicular to each other.
If one of them makes an angle of 60newton with the resultant.
and
The magnitude of force,
or
F = 100 N
So, the magnitude of force is 100 N.
