Density, streak, and geochemical signature through use of inductively coupled plasma mass spectrometry or Fourier transform infrared spectroscopy
<span>the amount of water a sponge can absorb depends on many factors. The material the sponge is made out of, the structure of the sponge and the size of the sponge all affect how much water the sponge can absorb.</span>
Answer:
Time period, T = 1.98 seconds
Explanation:
It is given that,
Mass of the block, m = 300 g = 0.3 kg
Force constant of the spring, k = 3 N/m
Displacement in the block, x = 3 cm
Let T is the period of the motion of the block. The time period of the block is given by :

T = 1.98 seconds
So, the period of the motion of the block is 1.98 seconds. Hence, this is the required solution.
Answer:
The magnitude of the applied force is 94.74 N
Explanation:
Mass of the block, m = 11 kg
Angle of inclination of the plane, 
Friction coefficient, 
Now,
Normal force that acts on the block is given by:
(1)
Now, to maintain the equilibrium parallel to ramp the forces must be balanced.
Thus
(2)
From eqn (1) and (2)




F = 94.74 N
