Answer:

During cold periods called 'ice age', large parts of Earth’s surface were covered with sheets of ice.

Explanation:

Ice age refers to the coldest period on earth.

The ice age was the period in which ice glaciers and sheets expand across the earth. That's why it is known as the cold periods.

The complete statement is: During cold periods called ice age, large parts of Earth’s surface were covered with sheets of ice.

Vikentia [17]

Answer:

The electromagnetic force

Explanation:

The electromagnetic force is one of the four fundamental forces of nature. Namely, they are:

- Electromagnetic force: it is the force exerted between electrically charged particles (and between magnetic fields). The force can be either attractive (if the two charges have opposite signs) or repulsive (if the two charges have same sign), and it acts over an infinite range.

- Gravitational force: it is the force exerted between objects with mass. It is always attractive, and it also has an infinite range of action. It is the weakest of the four fundamental forces.

- Strong nuclear force: it is the force that acts between protons and neutrons inside the nucleus, and it is responsible for keeping the nucleus together and preventing it from breaking apart (due to the electrostatic repulsion between protons)

- Weak nuclear force: it is the force responsible for certains nuclear decays, such as the beta decay, in which a neutron turns into a proton, emitting an electron and an antineutrino.

A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force)

salantis [7]

Answer:

The velocity with which the student goes down the bottom of glide is 12.48m/s.

Explanation:

The Non conservative force is defined as a force which do not store energy or get he energy dissipate the energy from the system as the system progress with the motion.

Given are

mass of the student 73 kg

height of water glide 11.8 m

work done as -5.5*10³ J

Have to find speed at which the student goes down the glide.

According to Law of Conservation of energy,

K.E =P.E+Work Done

mv²/2=mgh +W

Rearranging the above eqn for v

v = √2(gh+W/m)

Substituting values,

V = 12.48 m/s.

The velocity with which the student goes down the bottom of glide is 12.48m/s.
