The normal force of the ground on the skater depends on the skater's weight.
What is normal force?
This is the upward force on an object usually exerted by the ground due to the weight of the object acting downwards.
Vertical force on the skaterThe net vertical force on the skater is zero.
W - Fₙ = 0
W = Fₙ
where;
W is the weight of the skaterFₙ is the normal force of the skaterThe normal force of the skater is equal to the weight of the skater acting downwards.

Telescope A had an aperture of 15 cm while telescope B that of 5cm how many times of light gathering power does telescope A have compared with telescope B
Answers
Answer:
Light gathering power is related to the area of the lens aperature:
Aa / Ab = (15 / 5)^2 = 9 since the area of an aperature is proportional to the square of the radius

How does heat flow from one object to the other?
Answers
Answer:
Conduction, convection or radiation
Explanation:
Hope I could help. If you need more detail about one type, then coment below
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.

Prompt. Explain the difference between a solar eclipse and a lunar eclipse. Be sure to explain the positions of the earth moon and sun for each scenario
Answers
Answer:
Explanation:
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.

Density of solids What is your hypothesis (or hypotheses) for this experiment?.
Answers
I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.
What is density?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.

Do you think radio waves and x-rays are types of light?
Answers
Answer:
yes, radio waves and x-rays are type of light.
Radio waves definition (according to Britannica), is, “radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. The wavelengths of radio waves range from thousands of metres to 30 cm. These correspond to frequencies as low as 3 Hz and as high as 1 gigahertz (109 Hz).”
And the definition of x-rays (also according to Britannica), is, “X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 1016 to 1020 hertz (Hz).”
Which basically is what a light is.

What does it mean if electric field lines are close together versus farther apart ?
Answers
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.

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

A plane mirror forms a virtual image. give reasons
Answers
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

A) the current in the wire has created a gravitational field with its South Pole at the top of the rod
B) the current in the wire has created a magnetic field with its South Pole at the top of the rod.
C) the current in the wire has created a magnetic field with its North Pole at the top of the rod.
D) The current in the wire has created a gravitational field with its North Pole at the top of the rod
Answers
Answer:
did you ever get the answer
The current in the wire has created a magnetic field with its north pole at the top of the rod. This is because the magnetic field influences electric currents. Thus, the correct option is C.
What is a magnetic field?A magnetic field is a vector field which describes the magnetic influence on a moving electric charge, electric current, and magnetic material. A moving charge in a magnetic field which is experienced a force perpendicular to the own velocity and to the magnetic field.
The magnetic field is also referred to as the field where magnetic forces act to shape an electrical current. The only material or body which is capable of altering an electrical current in a magnetic field is the presence of another magnetic field in the space.
Therefore, the correct option is C.

calculate the kinetic energy of a ball of mass 50g travelling of 30m/s how much work will need to be done to stop the ball
Answers
Explanation:
Ke=1/2mv^2
M=0.05kg
KE=1/2×0.05×90
KE=22.5J
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.
What is kinetic energy?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.
