Answer:

Option A is correct

Explanation:

Direction of spin can be measured because of the behaviours of the particle as it goes through a magnetic field and the size of the spin is dependant on type of particle.

Which force diagram accurately represents a satellite in orbit around Earth?
Anit [1.1K]

Answer:

First choice

Explanation:

A satellite in orbit around Earth experiences only one force: the gravitational attraction exerted by the Earth on it. This force is labelled with F_g. In space, there are no other forces acting on the satellite.

The force of gravity acts as centripetal force, "pulling" the satellite towards the centre of its circular orbit. The inertia of the satellite (which has an initial velocity) tends to keep it moving straight, so the combination of these two effects (inertia and force of gravity) results into the circular motion of the satellite.

Es - Which of the these is a balanced chemical equation?
nalin [4]
<h3>Answer:</h3>

2CO(g) + O₂(g) → 2CO₂(g)

<h3>Explanation:</h3>

What is a  balanced chemical equation?

  • A balanced chemical equation is one that has equal number of atoms of each element involved in the reaction on both side of the equation.

How do we balance chemical equations?

  • Balancing chemical equations is a try and error process that involves putting appropriate coefficients on the reactants and products in a chemical reaction.

Why is it important to balance chemical equation?

  • Chemical equations are balanced so as to obey the law of conservation of mass.

In this case; the balanced chemical equation for the reaction between carbon monoxide and oxygen gas is given by;

2CO(g) + O₂(g) → 2CO₂(g)

  • This is because there are 2 carbon atoms and 4 oxygen atoms on both the reactant and product side.

When the Voyager 2 spacecraft sent back pictures of Neptune during its flyby of that planet in 1989, the spacecraft’s radio sign
Ratling [72]

Answer:

<em>a) 28877 AU</em>

<em>b) 1.795 sec</em>

<em></em>

Explanation:

Time it took the radio signal to reach earth = 4 hours = 4 x 3600 = 14400 s

speed of radio signal = speed of vacuum speed of light  = 3 x 10^8 m/s

Distance traveled by this signal = speed x time

distance = 3 x 10^8 x 14400 = 4.32 x 10^12 m

One Astronomic unit AU is the distance between the Earth and the sun and it is approximately equal to 1.496 x 10^8 m

The distance traveled by the signal in AU = (4.32 x 10^12)/(1.496 x 10^8) = <em>28877 AU</em>

b) The minimum separation between Earth and Mars = 0.36 AU

This distance = 0.36 x 1.496 x 10^8 = 538560000 m

Time that will be taken for a radio signal to travel this distance = distance/speed

==> 538560000/(3 x 10^8) = <em>1.795 sec</em>
