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

Answers

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.

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.

why are north and south poles important to magnets

Answers

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

Answers

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​

Answers

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

Answers

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.

I think it's b and I'm sorry if it's wrong

Given ↷

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 2k

so,

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 ✓
