Viscosity is the fluid friction that exists between the atoms. The atoms of liquid experience a strong force of attraction upon contact. Due to this attraction, the atoms of liquid resist the flow of motion. The higher the resistance is shown by a liquid, the higher will be its viscosity.
Answer:
The total momentum of the cat and the dog is, p = 2.4 kg m/s
Explanation:
Given,
The mass of the cat, m = 800 g
= 0.800 kg
The mass of the dog, M = 1000 g
= 1 kg
The velocity of the cat taken positive x direction, v = 8 m/s
The velocity of the dog, V = - 4 m/s
The momentum of the body is defined as the product of its mass and velocity.
p = mv
The momentum of the cat,
p₁ = 0.8 x 8
= 6.4 kg m/s
The momentum of the dog,
p₂ = MV
= 1 x -4
= -4 kg m/s
The total momentum,
p = p₁ + p₂
= 6.4 + (-4)
= 2.4 kg m/s
Hence, the total momentum of the cat and the dog is, p = 2.4 kg m/s
For some mysterious reason, we can't see the graph.
On a position/time graph, constant velocity is represented by a <em>straight line</em>. Depending on the velocity, the line may be sloping up, sloping down, or horizontal. The only thing the line on the graph <u><em>CAN't</em></u> be is vertical.
Answer:
The kinetic energy of the cell phone is 9J
Explanation:
The kinetic energy is the energy possessed by a body by virtue of motion.
The kinetic energy is expressed as
KE= 1/2m(v)²
Given data
Mass of cell phone m= 80g--to kg=80/1000= 0.08kg
Velocity of cell phone v= 15m/s
Substituting our given data we have
KE= 1/2*0.08(15)²
KE= (0.08*225)/2
KE=18/2
KE= 9J
