Ice of mass 50g at 0°C was completely melted by 70% of the total heat energy supplied. Calculate the total heat energy supplied [Specific latent heat of fusion of ice = 336Jg−1]
A. 2400J B. 6800J C. 7251J D. 24000J Correct Answer: Option D D. 24000J Explanation The quantity of heat needed to melt ice = mL (where m is the mass of ice and L is the specific latent heat of fusion of ice) Q = 50×336=16800J but this is 70% of the total heat...The energy stored in the spring of stiffness constant k = 2000Nm−1 when extended 4cm is?
A. 0.16J B. 1.60J C. 16.00J D. 160.00J Correct Optiom: Option A A. 0.16JWhich of the following graphs correctly represents the relationship between the kinetic energy (K.E) and the displacement (d) from point of release of a swinging pendulum bob?
A. I B. II C. III D. IV Correct Answer: Option B B. IIA body can undergo the following types of motion except?
A. random B. rotational C. translational D. relative Correct Answer: Option D D. relative Explanation Relative motion is the calculation of the motion of an object with regard to some other moving object. Hence, relative motion is not a type of...Products
