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\(^2\)
the density of water is less than that of the object
the pressure is low just below the water surface
it experiences an upthrust
the tension in the string neutralizes part of the weight
Correct answer is C
No explanation has been provided for this answer.
