Why does the layer of glass in a solar cell need an antireflective coating?
A. To maximize the energy absorbed by the solar cell
B. To help the cell conduct the charge that is produced
C. To give the layer a negative charge
D. To give the layer a positive charge
the answer is A
Answer:
The Anti Reflective Coating on a solar cells helps to increase the amount of light absorbed into the cell. This anti reflective coating is very much needed as the reflection of a bare silicon solar cells is over 30%. For the thin AR Coating, silicon nitride or titanium oxide is used.

What helps a race car to not slide all over the race track?
Answer: Gently reduce pressure on brakes – if on ice, push in the clutch to let the wheels turn freely.
Turn the steering wheel quickly – look and steer in the direction you want to go.
Counter-steer – as the vehicle gets back on course, counter-steer to avoid skidding in the opposite direction.

Why does the North star not move but the other stars move
Answer:
it's the star in the center of the star field
Explanation:
Why Doesn't Polaris Move? Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. ... Polaris is the star in the center of the star field; it shows essentially no movement. Earth's axis points almost directly to Polaris, so this star is observed to show the least movement
explain Newtons Laws
1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”
This law also called law of inertia
2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”
3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.
These forces are called action and reaction forces
hope it's helpful ❤❤❤❤❤❤

why are north and south poles important to magnets
Answer:
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

You push on a light object (small mass) with a certain amount of force and it moves. If you push just as hard on a heavier object (large mass) it will move _____ the light object. a. Faster than b. slower than c. the same as
Answer: B
Explanation:
It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force
calculate capacitance if Q=7mc and delta V=12V
Answer:
Capacitance = 0.00058 Farads
Explanation:
Given the following data;
Charge, Q = 7mC to Coulombs = 7/1000 = 0.007C
Velocity = 12V
To find the capacitance;
Capacitance = charge/potential difference
Substituting into the equation, we have;
Capacitance = 0.007/12
Capacitance = 0.00058 Farads

TRUE or FALSE: An object's mass changes depending on which planet it is located.
A. TRUE
B. FALSE
Answer:
Fales
Explanation:
That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = T[/tex]
Hence ,option B is correct ✓
According to Newton’s second law of motion, what is equal to the acceleration of an object?
Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Explanation:
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.
