Answer:
Weight can be zero when acceleration due to gravity is zero. The value of 'g' is maximum on the surface of the Earth and decreases on going inside the surface or above the surface of the Earth. Thus, the weight of a body will be zero at the centre of the Earth.
Explanation:
I believe the answer would be lungs
Answer:
range = 276.8 km, time = 142 s
Explanation:
Explanation:
Given that,
Mass of the block, m = 5 kg
Spring constant, k = 2000 N/m
The block is pulled down 5.0 cm from the equilibrium position and given an initial velocity of 1.0 m/s back towards equilibrium.
(a) The angular frequency is given by :
Since, , f is frequency
(b) The velocity of particle executing SHM is given by :
x is displacement from equilibrium position
(c) The total mechanical energy of the motion in SHM is given by :
Hence, this is the required solution.
