IT IS A : VELOCITY (Please give me brainliest)
Answer:D-550 N
Explanation:
Given
mass of student=50 kg
at particular instant elevator is moving downward with acceleration of 1 m/s^2
Net weight of man shown by scale will be more than his actual weight as elevator is decelerating
let N be the normal reaction on man thus
and Normal reaction will be shown by scale as apparent weight
Answer:
Natural frequency=21.40 Hz
Time= 0.2936 seconds
Explanation:
Idealizing the question as a cantilever beam with point load of mass M as 20 tons
Lateral stiffness, where l is length given as 10 m, E is Young’s modulus given as 30GPa and I is inertia where for a circular cross-section is given by
k== 9160884.178
k=
To find the frequency, , the mass m is given as 20 tons or 20000 Kg
=21.40196741 Hz
Natural frequency=21.40 Hz
Time period,
T==0.2935798 seconds
T=0.2936 seconds
Answer:
8.803 s
(but this is only if it's a free fall, which we assume since we didn't get the mass of the hulk)
Answer:
Electric energy is the answer
Explanation:
Just think
