In energy terms, electrical potential energy in the battery is converted into kinetic energy of moving electrons.

Explanation:

Answer:

1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.

2. The image cannot be projected onto a screen also.

3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.

Thanks!

Answer:

becaise the light does not actually pass through the image

Based on scientific information, the direction that heat generally flow from is: A. hot to cold.

Heat is also known as thermal energy and it refers to a form of energy that is only transferred from an object to another due to a difference in temperature.

During the process of heat conduction, heat would only be transferred between objects that are having different levels of temperature and objects that are directly in contact with one another.

In conclusion, heat is generally transferred from a hot object to a cold object as a result of their varying temperature.

kinetic energy of the ball of mass 50 g and velocity of 300m/s is 22.5 J. The work done need to stop the ball is equivalent to its kinetic energy. Thus, 22.5 J of work done is needed.

The kinetic energy of an object is the energy generated by virtue of its motion. It is related to its mass and velocity by the expression written below:

Ke = 1/2 m v²

Thus, kinetic energy increases with mas and velocity.

Given that, mass of the ball = 50 g = 0.05 kg

velocity of  the ball = 30 m/s

then Ke = 1/2  × 0.05 kg × 30 m/s × 30 m/s = 22.5 J.

The energy of the body when it is moving is in the form of kinetic energy. This energy of the body is equivalent to the work done on the body to stope it. Therefore, work done on the ball needed to stop it is 22.5  J.

Eclipse happens when a large object gets in the way of another object; casting its shadow over it.

Solar eclipse happens when the moon get in between the sun and earth. It blocks sun light and causes its shadow over the sun as seen from earth.

Lunar eclipse happens when the earth is in between the sun and moon. It blocks sun light from reflecting off the moon surface so there is a shadow on the moon as seen from earth.

The normal force of the ground on the skater depends on the skater's weight.

This is the upward force on an object usually exerted by the ground due to the weight of the object acting downwards.

The net vertical force on the skater is zero.

W - Fₙ = 0

W = Fₙ

where;

The normal force of the skater is equal to the weight of the skater acting downwards.

Thus, the normal force of the ground on the skater depends on the skater's weight.

Answer:

As a result, if the field lines are close together (that is, the field line density is greater), this indicates that the magnitude of the field is large at that point. If the field lines are far apart at the cross-section, this indicates the magnitude of the field is small. (Figure) shows the idea.

Here is your Answer:-

Heat flow relies heavily on the concept of conduction. Basically, the transfer of the heat energy relies on free electron diffusion. In order for the heat to move from one object or material to another, adjacent atoms vibrate against each other. This is caused by the electrons moving from one atom to another.

I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

I study if the volume or density of items determines whether solid objects float or sink in water in this scientific inquiry I did the experiment of density, mass, and volume using a rock and a standard-shaped piece of wood.

It is critical that the chosen piece of wood is larger than the rock and that the rock be tiny enough to fit inside the measuring cylinder. I see both the rock and a chunk of wood.

Hence I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.
