A bar magnet is placed on a table so that the north pole faces right.
Katena32 [7]

The correct answer is C. They are pointing right to left.


Explanation.

A magnet has two poles, a north pole and a south pole.  When dealing with magnets, we define the concept of a magnetic field. A magnetic field represents the effect of the magnet on magnetic materials and moving charges in the space around the magnet. For every magnet, the magnetic field lines always point away from the north pole of the magnet towards the south pole. Since the north pole of this magnet faces right, the magnetic field lines point towards the left.

The correct answer is C. They are pointing right to left.

The world energy consumption was about 6*10^22 J. How much area must a parallel plate capacitor need to store this energy Assume
Nastasia [14]

Answer:

A = 5 \times 10^{32} m^2

Explanation:

As we know that the energy stored in the capacitor is given as

Q = \frac{1}{2}CV^2

here we know that

Q = 6 \times 10^{22} J

also we know that

V = 5 Volts

now we have

6 \times 10^{22} = \frac{1}{2}C(5^2)

C = 4.8 \times 10^{21} F

now we know the formula of capacitance

C = \frac{\epsilon_0 A}{d}

4.8 \times 10^{21} = \frac{(8.85 \times 10^{-12})(A)}{1}

A = 5 \times 10^{32} m^2

Suppose two children push horizontally, but in exactly opposite directions, on a third child in a sled. The first child exerts a
anyanavicka [17]

Answer:

Please, read the anser below

Explanation:

1. In order to calculate the acceleration of the children you use the Newton second law for the summation of the implied forces:

F_2-F_1-F_f=Ma          (1)

Where is has been used that the motion is in the direction of the applied force by the second child

F2: force of the second child = 92N

F1: force of the first child = 79N

Ff: friction force = 5.5N

M: mass of the third child = 24kg

a: acceleration of the third child = ?

You solve the equation (1) for a, and you replace the values of the other parameters:

a=\frac{F_2-F_1.F_f}{M}=\frac{96N-79N-5.5N}{24kg}=0.48\frac{m}{s^2}

The acceleration is 0.48m/s^2

2. The system of interest is the same as before, the acceleration calculated is about the motion of the third child.

3. An image with the diagram forces is attached below.

4. If the friction would be 150N, the acceleration would be zero, because the friction force is higher than the higher force between children, which is 92N.

Then, the acceleration is zero

If an object doubles in mass, what happens to its inertia?
son4ous [18]

Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity.


HENCE The inertia will also be doubled
