Which of the following assumptions is made in a simple pendulum experiment? the
suspending string is inextensible
bob has a finite size
bob has a definite mass
initial angle of oscillation must be large
Correct answer is A
No explanation has been provided for this answer.
u2g
\(\frac{3u^2}{2g}\)
\(\frac{u^2}{g}\)
\(\frac{u^2}{2g}\)
Correct answer is D
Using V2 = U2 - 2gS
V = 0ms-1 at greatest height
S = \(\frac{u^2}{2g}\)
Which of the following is in a neutral equilibrium?
a heavy weight suspended on a string
a cone resting on its slant edge
a heavy-based table lamp
the beam of a balance in use
Correct answer is B
No explanation has been provided for this answer.
Momentum
Kinetic energy
Potential energy
Acceleration
Correct answer is D
Potential energy is energy possessed by a body by virtue of its position. when the body is above the ground, it possesses kinetic energy.
acceleration due gravity is at constant value of 10m/s\(^2\)
