As we know, the moon is a satellite of our earth, what is the
theoretical period of the moon? The average radius of the
moon's orbit is 3.84 108 m and the mass of the earth is 5.97 x
1024 kg (in hours, G = 6.67 x 10-9 N (m/kg) 3).

Answer:

4620

Explanation:

Answer:

true

Explanation:

The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.

Explanation:

These three maintain the overall health of the person being. Take for instance an example a cake, it has layers that make the overall cake. So it is with the persons health, it takes all three of these feilds to make the overall health.

Answer: Fg < Fq

Explanation: just took the lab test edge 2020

The electromagnetic force is greater than the gravitational force option third Fg < Fq is correct.

It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge separated by r is determined by the charge potency of each charge as well as the separation distance between them.

Force of gravity is given by:

[tex]\rm F_g=\dfrac{Gm_1m_2}{r^2}[/tex]

The electrostatic force is given by:

[tex]\rm F_q = \dfrac{kq_1q_2}{r^2}[/tex]

On the atomic scale, electrons, for example, have very little mass but a very large charge. As a result, electromagnetic forces rule.

Thus, the electromagnetic force is greater than the gravitational force option third Fg < Fq is correct.

Given:

[tex]g= 6.003 \ \frac{m}{s^2}\\\\G= 6.67 \times 10^{-11} \ \frac{N - m^2}{kg^2}\\\\M=?\\\\radius= 2,400 \ km\\\\[/tex]

Answer:

C. It keeps the electric current flowing in one direction.

Explanation:

just got it correct on my quiz.

The commutator in a DC generator keeps the electric current flowing in one direction option (C) is correct.

A direct current generator's principal job is to transform mechanical energy into electricity. Internal combustion engines, water, gas, steam turbines, and even hand cranks are all sources of mechanical energy for DC generators.

The commutator in a DC generator converts the alternate current into the direct current.

Thus, the commutator in a DC generator keeps the electric current flowing in one direction option (C) is correct.

Answer:

Weight. Recall that the acceleration of a free-falling object near Earth's surface is approximately g=9.80m/s2 g = 9.80 m/s 2 . The force causing this acceleration is called the weight of the object, and from Newton's second law, it has the value mg.

Explanation:

Answer:

A

Explanation:

Given that a stone dropped from the top of a 80m high building strikes the ground at 40 m/s after falling for 4 seconds. The stone's potential energy with respect to the ground is equal to its kinetic energy. (use 9 - 10 m/s)

O at the moment of impact

2 seconds after the stone is released after the stone has fallen 40 m

when the stone is moving at 20 m/s

At the top of the hill, the P.E = mgh

P.E = 10 × 80 × m

P.E = 800m

At the moment of impact, K.E = 1/2mv^2

K.E = 1/2 × 40^2 × m

K.E = 1/2 × 1600 × m

K.E = 800m

Since both P.E and K.E are the same, we can therefore conclude that the stone's potential energy with respect to the ground is equal to its kinetic energy at the moment of impact.

The correct answer is option A.

Answer:

Conduction, convection, and radiation

Explanation:

Conduction is the process in which energy is transferred from a hot body to a cooler body. Convection is a process by which heat is transferred as a result of the movement of heated fluid in the form of air or water. Radiation refers to the transmission of energy through a material medium.

Based on the information provided, a lava lamp could be used to provide an example of conduction, convection, and radiation.

Explanation:

A conductor allows electric current to pass through it. Hence, when conductors are connected in a closed circuit, current flows.

All the resistors in Q2 are connected in series. In a series connection, the current across all the resistors is the same.

In a battery, chemical energy is converted to electrical energy by chemical reactions.

When a new resistor is connected in parallel to a circuit the current increases accordingly.
