Answer:

Explanation:

7.Conduction

Assuming the pot is cold and the heating element is hot: Heat will be transferred from the element to the pan via conduction because they are in contact with one another.

8.  C The moon

9.  A heat, light and sound energy.

When fireworks explode, chemical energy is transformed into thermal energy, mechanical energy, radiant energy, and sound energy.

10.A 70% light energy, 30% thermal energy

When the flashlight is turned on, the chemical energy is first transformed into electrical energy and then into light energy.

If number 10 is not correct then the answer is  C.

Answer:

reflect

Explanation:

In order to see the image of an object in a mirror, you must sight at the image; when you sight at the image, light will come to your eye along that line of sight.

Answer:

yeah its correct

Explanation:

As the ball spins, friction between the ball and air causes the air to react to the direction of spin of the ball. ... Therefore, when a soccer player kicks the ball right of center the ball spins counter-clockwise and the Magnus force acts left, causing the ball to curve left.

Answer:

A. Direction

Explanation:

Velocity is the speed of something heading in a certain direction. If speed or direction changes, the velocity changes.

Answer:

Acceleration occurs when an object changes its VELOCITY or DIRECTION or both

Explanation:

Answer:

Explanation:

When a wire of length L is moved with velocity v , perpendicular to magnetic field B , EMF will be produced at its two ends . EMF can be calculated with the help of following expression

EMF = BLv

As per this formula , EMF produced will not depend upon number of electrons in the magnetic field.

So B is the right choice.

Answer:

a. Net force = 40 Newton.

b. Acceleration = 8m/s²

Explanation:

Given the following data;

Force on postive x-axis = 90N

Force on negative x-axis = 50N

Mass = 5kg

a. To find the net force;

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

The net force is equal to the difference between the two forces applied because they are acting in opposite directions.

Net force = 90 - 50

Net force = 40N

b. To find the acceleration;

Acceleration = net force/mass

Acceleration = 40/5

Acceleration = 8m/s²

Answer:

KE increases and PE decreases.

Explanation:

POTENTIAL ENERGY (PE):

The potential energy of the rock depends upon the height of the rock, as given by the following formula:

P.E = mgh

Therefore, the potential energy will be highest at the initial point due to the highest height attained by rock. As the rock falls, its height will decrease as a result its potential energy will also decrease.

KINETIC ENERGY (KE):

The kinetic energy of the rock depends upon the velocity of the rock, as given by the following formula:

[tex]K.E = \frac{1}{2}mv^2[/tex]

Therefore, the kinetic energy will be zero at the initial point due to the zero velocity of the rock. As the rock falls, its velocity will increase as a result its kinetic energy will also increase.

Hence, the correct option will be:

KE increases and PE decreases.

Answer:

In classical mechanics, Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.

Answer:

K.E. = 1/2mv^2

Explanation:

v is velocity (a vector) not speed (a scalar) but they have the same magnitude

Answer:

So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.

Answer:

F = 3.15 N

Explanation:

Given electric charge, q = 6.3 μC

The magnitude of electric field, [tex]E=5\times 10^5\ N/C[/tex]

We need to find the electric force on the charge due to the electric field. The electric force is given by :

F = qE

Putting all the values,

[tex]F=6.3\times 10^{-6}\times 5\times 10^5\\\\F=3.15\ N[/tex]

So, the required force on the charge is 3.15 N.

Explanation:

In the supply curve, when the price of a good increases, A. The quantity of goods that are produced increases.

Supply simply means the quantity of goods and services that a supplier is willing to sell at a particular place, price and time.

In this case, when there's an increase in the price of goods, it should be noted that producers will supply more of the goods. This is done in order to generate more revenue.
