Correct Answer: Hooke's law
Explanation:
When you compress or stretch a spring, as soon as the stress is relieved, the spring attains its normal shape instantly. Its Elastic potential energy helps it do so. Generally, these elastic substances follow the Hooke?s law.
According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook?s Law can be summarised as F= ? k x. Here ?k? is the spring constant and ?x? is the displacement.
Correct Answer: Nearest peak to peak
Explanation:
Wavelength of a wave can be measured with the distance between two nearest crest and crest or nearest troughs. It is measured as armstrong units.
Correct Answer: All of the above
Explanation:
All of the factors that contribute to global winds are
1) Uneven warming of the earth by the sun
2) Coriolis Effect
3) Convection Cells
Correct Answer: If a micrograph is false-colored, it means that the computer has created the colour for the object since we know that the electron microscopes sees only black and white colours
Correct Answer: Nuclear energy
Correct Answer: convection
Explanation:
Convection is by far the most efficient and common way for heat to be transferred through liquids and gases. It occurs when some regions of a fluid get hotter than others, causing currents in the fluid that move it around to distribute that heat more evenly.
Correct Answer: cold, dense ocean water sinking and warmer water replacing it
Correct Answer: Circular motion of electrons
Explanation:
Magnetism in materials is due to circular motion of electrons.
Correct Answer: Air Pressure
Explanation:
The temperature at which water boils depends mainly on air pressure.
Correct Answer: TRUE
