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.

Determine the stopping location of the prize wheel. At this moment it is centered on the number 5. It is spinning with an energy of 6.19 J. It is slowing at a rate of 1.800 rad/s/s.
The disk is made from a wood with a density of 478.0 kg/m^3. The disk is 29.0 mm thick and has a radius of 33.0 cm.
Predict the angular displacement it will go through and predict the number on which the wheel will stop. To be safe, you will also get one number the right and to the left of the number you chose.
The wheel will spin clockwise. The wheel goes from 1 to 36.
Answer:
Thanks for the 50 points. Answer eill be always 29.0m
A construction worker pushes a wheelbarrow 15 m with a horizontal force of 17 N. How much work is done by the worker on the object?
Answer:
The work done by the worker on the object is 255 J
Explanation:
Work is defined as the force that is applied on a body to move it from one point to another.
When a net force is applied to the body or a system and this produces displacement, then that force is said to perform mechanical work. This work can be positive if the system gains energy or negative if the system loses energy.
In the International System of Units, work is measured in Joule. Joule is equivalent to Newton per meter.
The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that travels the point or the object that moves.
In this case, the angle between the force and the displacement is 0 degrees. Then the cosine of 0 degrees will have a value of one. So work is calculated as the multiplication between force and distance:
W= 17 N* 15 m
Solving:
W= 255 J
The work done by the worker on the object is 255 J

An object moving with a speed of 35 m/a and has a kinetic energy of 1500j, what is the mass of the object
Explanation:
Speed or velocity (V) = 35 m/s
Kinetic energy (K. E) = 1500 Joule
mass (m) = ?
We know
K.E = 1/2 * m * v²
1500 = 1/2 * m * 35²
1500 * 2 = 1225m
m = 3000 / 1225
m = 2.45 kg
The mass of the object is 2.45 kg

Explanation:
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. ... This means that some individuals would survive and be able to reproduce and generate more offspring.

What work is done when a person lifts a 1.6 kg package and places it on a shelf 2.4m high?
Answer:
Explanation:
Work is the dot product of force and distance
[tex]W = F*d=Fd*\cos(theta)[/tex]
The only force acting on this box is the force of gravity (weight) which is mass*gravity
F = (1.6)(9.8) = 15.68N
The angle is the angle between the force and distance. In this case it is zero, therefore cos(Ф) = 1
[tex]W=15.68*2.4=37.6J[/tex]

What is the weight of a dog that has a mass of 47.0 kg?
Answer:
while we often confuse mass with weight, 47 kg is 47 x 9.8 = 460.6 Newtons. 9.8 is acceleration of gravity in m/sec/sec

Why did you need to heat the water to make the nectar?
A. Heating the water increases the solubility of the sugar.
B. Heating the water decreases the melting point of the sugar.
C. Heating the water increases the boiling point of the sugar.
D. Heating the water increases the particle motion of the sugar.
Answer:
D
Explanation:
Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.

How does Earth's movement affect how the Sun is seen? The Sun is stationary, but Earth's rotation makes it appear to move east to west across the sky. Earth's rotation around the Sun makes the Sun appear to move across the sky every 365 days. The Sun and Earth move around each other, so the Sun moves east to west across the sky. The Sun is stationary, but Earth's clockwise rotation makes it appear to move west to east across the sky.
Answer:
The manner in which the Earth's movement affect how the Sun is seen is;
The Sun is stationary, but Earth's rotation makes it appear to move East to West across the sky
Explanation:
The Earth's movement affect the way the Sun is seen
The Sun appears to rise in the Eastern part of the sky and continues in motion till the it sets at the Western part of the sky
However, the Sun does not actually move relative to the Earth as seen in the sky. The observed motion of the Sun is due to the counterclockwise rotation of the Earth about its axis
Therefore, the Earth's movement affect the way the Sun is seen by making the Sun appear to move across the sky from East to West
Answer:
The sun stays still but the rotation of the earth makes it look like it goes east to west.
Explanation:
A man driving a car sees a deer crossing the road and brakes the car with a force of 100 N. The car stops after traveling 5m. What is the work done on the car?
Answer:
Workdone = 500Nm
Explanation:
Given the following data;
Force = 100N
Distance = 5m
To find the workdone;
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the equation, we have
[tex] Workdone = 100 * 5 [/tex]
Workdone = 500Nm
