Answer:
the bigger the mass, the smaller the acceleration and the smaller speed
Explanation:
this can be proven from the formula F = ma
F = m×speed/time
Or a practical example is that of a heavy object and a light object if pushed with the same force, it'll be observed that the small object moves faster or with a greater speed than the heavy object
Answer:
1.21 m/s
Explanation:
Given :
2 loudspeakers
F2 - F1 = 2.86 Hz
Speed of sound, V = 343
Fo = frequency when listener is at rest = 406Hz
To obtain the walking speed Vo, speed as observer moves away from speaker ;
Vo = [(F2 - F1) * V] ÷ 2 * Fo
Vo = [2.86 * 343] ÷ (2 * 406)
Vo = 980.98 / 812
Vo = 1.2081034
Vo = 1.21 m/s
Answer: 5 gm/cc
Explanation:
200 gm/40 cc
= 5 gm/cc
Answer:
A theory changes based on new observations and testing.
Explanation:
A scientific theory is a product of multiple trials and repeated experiments. It usually follows after carefully conducting and testing the validity of the hypothesis.
A scientific theory provides an explanation into how something behaves.
A law just states a finding will not explain it.
Most theories are tenable and can be improved upon when new observations and testing are carried out.
Answer:
turbine
Explanation:
Tidal energy is produced in the Tidal power plant to produce electricity. The kinetic energy is produced because of the energy of the tides in the form of moving water. This energy is converted into electricity with the help of power turbines. The turbine plays an important role in the production of electricity. The fluid that is used in the turbine contains potential energy. The moving turbine converts the potential energy to kinetic energy and the energy is collected in the form of electricity.
