It goes in this order. Medium, density, viscosity
Kinetic energy is equal to half of an objects mass multiplied by the velocity squared.
Answer:
Substance 1 because it became a liquid faster
Explanation:
Using a machine can speed up work very quickly as machines are way faster than humans. Machines also do not get exhausted unlike humans so can work over a long period of time non stop.
Answer:
Please find the answer in the explanation.
Explanation:
Balancing the forces acting on a body is not enough to establish equlibrium because of the principle of moment say that:
1.) For equilibrium to be attained, the sum of clockwise moment must be equal to the sum of anticlockwise moments.
2.) The sum of upward forces must be equal to the sum of the downward forces
According to the definition of moment, is the product of force and perpendicular distance.
Therefore, the perpendicular distance is needed to be considered.
