Answer: Glare appears on a computer screen when light from the surroundings reflects off of the screen's surface. Some computer screens have a special coating to reduce glare. Which best explains how the coating works? The surface of the coating is rough, so light that shines on it gets scattered in many directions.
HOPE THIS HELPS IF NOT SORRY
The surface of the coating is rough, so light that shines on it gets scattered in many directions best explains how the coating works.
What is coating?A coating is a protective layer that is put to the surface of an item, The coating can be applied for ornament and jewelry.
Paints are a type of coating that protect the surface of the material and also used for its decoration as well as also used in corrosion prevention.
When any light is to fall on any rough surface in that condition, the light get scattered in many directions.

A force of unknown magnitude is applied to push a 115kg bobsled down a flat, frictionless surface with an acceleration of 7.8 m/s2. What is the net force on the sled?
Answer:
Explanation:
Since we have no friction and we also have no angle of inclination, this is a straightfoward force problem, where
F = ma
Filling in,
F = (115)(7.8) so
F = 9.0 × 10¹ N

What happens to the gravitational force between two objects when the distance between them increases by 3 times?
Answer:
it decrease by 9 times
Explanation:
If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).
I have a bottle of gas, the bottle can expand and contract. Initially the gas is at 1 kpa of pressure and a volume of 1 Liter, at a temperature of 290 K. Then the Temperature went to 390 K and the volume of 1.1 Liter. What is the New Pressure? Please help I have been asking this for weeks
Answer:
P₂ = 1.22 kPa
Explanation:
This problem can be solved using the equation of state:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
where,
P₁ = initial pressure = 1 KPa
P₂ = final pressure = ?
V₁ = initial Volume = 1 liter
V₂ = final volume = 1.1 liter
T₁ = initial temperature = 290 k
T₂ = final temperature = 390 k
Therefore,
[tex]\frac{(1\ kPa)(1\ liter)}{290\ k} =\frac{(P_2)(1.1\ liter)}{390\ k}\\\\P_2= \frac{(1\ kPa)(1\ liter)(390\ k)}{(290\ k)(1.1\ liter)}[/tex]
P₂ = 1.22 kPa
how do iquantum tunel through a wall and how long will it take me?
Answer:
The phenomenon known as "tunneling" is one of the best-known predictions of quantum physics, because it so dramatically confounds our classical intuition for how objects ought to behave. If you create a narrow region of space that a particle would have to have a relatively high energy to enter, classical reasoning tells us that low-energy particles heading toward that region should reflect off the boundary with 100% probability. Instead, there is a tiny chance of finding those particles on the far side of the region, with no loss of energy. It's as if they simply evaded the "barrier" region by making a "tunnel" through it.

A child easily pushes an empty shopping cart around the store. As the cart fills, the child has to exert more force to keep the shopping moving and keep up with his mom. Which law is best supported by this example?
A. Newton's First Law
B. Newton's Second Law
C. Newton's Third Law
D. The law of definite proportions
Answer:
B Newton's second law
Explanation:
An empty grocery cart is easier to move because there is less mass in an empty cart compared to a full cart. Newton's second law state that an object's acceleration depends on the mass of the object and the force applied.
PLEASE HELP 15 POINTSexplain properties and importance of light and how it separates into colors
Answer:
It is not a property of light. It is your eyes and brain.
Specifically, the three kinds of cone cells in our eye that are sensitive to different ranges of the electromagnetic spectrum. The fact that there are three means that color is three dimensional, and is the reason the pure colors form a circle even though the spectrum of wavelengths is linear.
Visible light is part of the electromagnetic spectrum; light waves of different frequencies and wavelengths are distinguished as colors by the human eye. A prism can separate the colors of white light (dispersion) because different frequencies of light have different refractive indices for a given material.
A 4.03 x 10-5 F capacitor stores 5.15 x 10-3 J of energy. What is the voltage across the capacitor?
Answer:
V = 0.06255 Volts
Explanation:
Given the following data;
Capacitance = 4.03 * 10^{-5} F
Energy = 5.15 * 10^{-3} J
To find the voltage across the capacitor;
Mathematically, the energy stored in a capacitor is given by the formula;
E = ½cv²
Where;
C is the capacitor
E is the energy stored
v is the voltage.
Substituting into the formula, we have;
5.15 * 10^{-3} = ½ * 4.03 * 10^{-5} * v²
0.00515 = 0.00002015 * v²
V² = 0.00002015/0.00515
V² = 0.003912
Taking the square root of both sides, we have;
V = √0.003912
V = 0.06255 Volts

what are the variables in an experiment that tests the distance honey flows at different temperatures? identify the independent variable (the one we can control) and the dependent variable (the one we cannot control).
Answer:
The distance that the honey flowed would be the dependent or outcome variable and the temperature of the honey would be the independent variable.
The dependent variable is what is being measured in an experiment. You can remember it by thinking “it depends on what you’re changing.”
The independent variable in an experiment is what is being changed. You can remember this by thinking “the Independent variable is what I as the scientist change.”
Explanation:
mark me brainliest plz
In the experiment " Temperature" is dependent variable and the distance honey flows is independent variable.
What is independent variable ?It is the factor that one can purposely control or change to observe its effect , is called independent variable.
What is dependent variable ?It respond to the change in the independent variable , is called dependent variable.
Hence temperature is dependent and distance honey flow is independent variable.

A tennis ball and a bowling ball are both rolled down a bowling lane. If the
balls are rolling in the same direction at the same speed, which of the
following is true?
A. The balls have the same momentum because they have equal
velocities.
B. The tennis ball has greater momentum because its mass is less
than the mass of the bowling ball.
C. The balls have no momentum because they have equal velocities,
D. The bowling ball has greater momentum because its mass is
greater than the mass of the tennis ball.
Answer:
D. The bowling ball has greater momentum because its mass is
greater than the mass of the tennis ball.
Explanation:
The momentum of a body is defined as the product of mass and velocity. That is;
p = mv
This implies that the momentum of a body depends both on its mass and velocity respectively.
The question clearly states that the tennis ball and the bowling ball have the same speed and are rolling in the same direction. However, the bowling ball has a larger mass compared to the tennis ball hence it possesses a greater momentum than the tennis ball.
