Which of the following is a derived unit?
A body timed 20 oscillations of a certain pendulum three times and obtained 44.3s, 45.5s and 45.7s respectively. Calculate the mean period of oscillation of the pendulum
A body of mass M1 moving with a velocity U collides with a stationary body of mass M2 and both move with a common velocity V lf linear momentum is conserved, which of the following expressions correctly represents V?
A body of mass m = 0.5 kg is suspended by a string and pulled by a horizontal force of 1g N as shown in the 12N diagram: Calculate the tension T in the String if the body is in equilibrium. [Take g as 10ms-1]
A particle starts from rest and moves with a constant acceleration of 0.5 ms-2? Calculate the time taken by the particle to cover a distance of 25m.
A block of material of volume 2 X 1O-5m3 and density 2.5 x 10-3 kgm-3 is suspended from a spring balance with half volume of the block immersed in water. What is the reading of the spring balance? (Density of water =1.0x103 kg m-3 g = 10 ms-2).
