Two statements describe reasons a solar cell must contain semiconductors :
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.
C. Semiconductors serve as a source of electrons to form an electrical current.
What is Photoelectric effect?Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
When the semiconductor is exposed to light, it absorbs energy and transfers it to the material, due to which energy reaches to negatively charged particle (electron), which allows the electron to flow in the material as electric current .
hence , correct option will be :
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

Mr. Chang's class participated in a science experiment where they placed three substances outside in the sunlight to determine which substance would increase in temperature more quickly. How would the motion of the particles of each substance be described if they are allowed to sit in the Sun for a duration of 10 minutes?
Choices:
The particles do not change in motion because the substances are undisturbed.
The particles of each substance begin to speed up and move farther apart as the temperature increases.
The particles of each substance begin to slow down and move closer together as the temperature increases.
The particles of each substance speed up and slow down simultaneously, but remain in a fixed position as the temperature increases

Explanation:
When molecules are left in the sun, it heats up. When molecules heat up, the begin to vibrate rapidly. The sun is not constant as it could get blocked by clouds, so it would, at times, slow down the movement of the molecules. The answer is most likely D.

This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century.

4. Vector A is 7.00 units in length and points along the positive x-axis. Vector B is 5.00 units in length and points along the negative x-axis. find the magnitude and direction of A+2B 1 point
Answers
Answer:
Since the two vectors form a right angle, no components need to be found for the resultant vector - we already have them!
Vector R's x-component = 3.00 units
Vector R's y-component = 4.00 units
To solve for the magnitude of the displacement, use the distance formula: Square Root of [(3)^2 + (4)^2], which equals 5 units.
To solve for the direction of the displacement, plug in -4 (remember where it was pointing) for y and 3 for x. Tan-1(-4/3) = -53.13°, or 53.13° south of east.Please Mark as Brilliant
The magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.
What is vector quantity?
A vector quantity is a quantity with both magnitude and direction.
Given is vector A is 7.00 units in length and points along the positive x-axis. and vector B is 5.00 units in length and points along the negative x-axis.
Vector A = 7 a[x]
Vector B = - 5 a[x]
Therefore, the given expression to be evaluated is -
C = A + 2B
C = 7 a[x] + 2(- 5 a[x])
C = 7 a[x] - 10 a[x]
C = - 3 a[x]
So, the magnitude of vector C is -
|C| = 3
It is directed along the negative x - axis.
Therefore, the magnitude of vector C is |C| = 3 and It is directed along the negative x - axis.

hows a 170 g hamster sitting on an 830 g wedge-shaped block. The block, in turn, rests on a spring scale. An extra-fine lubricating oil having μs=μk=0 is sprayed on the top surface of the block, causing the hamster to slide down. Friction between the block and the scale is large enough that the block does not slip on the scale.
Answers
The complete question with the scale is missing, so i have attached it.
Answer:
930 g
Explanation:
The block surface is frictionless, therefore, the only force that can possibly be applied to the block from the hamster will be the normal force.
Now, the force of gravity on the hamster acts downward and equals mg. Hence, The normal component will be;
F_n = mgcosθ.
Now, if we Assume that the scale does not respond to horizontal force component, the downward component of the normal force will be expressed as;
F_d = F_n(cosθ)
The scale measures the downward component.
Earlier, we saw that; F_n = mgcosθ
Thus; F_d = mgcosθ × cosθ
F_d = mg(cos²θ)
Now, when the friction was high, the measurement of the scale was;
(m+ M)g
Where ;
m = mass of hamster
M = mass of block
Therefore, when the friction is removed the scale measurement is;
mgcos²θ + Mg or (mcos²θ + M)g
But this is in units of Newton's.
Thus;
Measurement in kg is;
(mcos²θ + M)
We are given;
m = 170 g = 0.17 kg
M = 830 g = 0.83 kg
From the attached scale image,
θ = 40°
Thus;
Measurement = (mcos²θ + M) = ((0.17 cos²40) + 0.83) = 0.93 kg or 930g

For a substance to change from a liquid to a solid, what must happen to its
particles?
O A. They must lose enough of their kinetic energy that their movement
is influenced by the attractions between them.
B. They must gain enough kinetic energy to allow them to move
freely while still being attracted to one another.
C. They must lose enough of their kinetic energy so that the
attractions between them hold in place as they vibrate.
D. They must gain enough kinetic energy to break out of their rigid
structure and move independently.
Answers
Answer:
C. They must lose enough of their kinetic energy so that the attractions between them hold in place as they vibrate.
Explanation:
The "kinetic energy" refers to the energy of an object when it is moving. This is directly proportional to the object's "thermal energy." If the kinetic energy of an object increases, the thermal energy increases and if the kinetic energy decreases, the object's thermal energy decreases as well.
Changing the phase of an object from liquid to solid means that the object will be subjected to low temperature. This means the thermal energy will decrease as well as the kinetic energy. This is known as "freezing." The object needs to lose enough kinetic energy. This results to its particles moving closer together in an attractive force.
So, this explains the answer.

Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, what is the minimum horizontal velocity a diver must have to clear them?
Answers
Answer:6.5 m/s
Explanation:Look at the image I believe that's the answer
The horizontal velocity of the diver would be 6.522 meters / seconds.
What are the three equations of motion?There are three equations of motion given by Newton
v = u + at
S = ut + 1/2×a×t²
v² - u² = 2×a×s
As given in the problem, Divers at Acapulco dive from a cliff that is 61 m high. If the rocks below the cliff extend outward for 23 m, then we have to find out the minimum horizontal velocity a diver must have to clear them,
By using the second equation of motion in the vertical direction,
s = ut + 0.5at²
61 = 0+ 0.5×(-9.81) ×t²
t² = 61/(0.5×9.81)
= 12.43
t = 3.526 seconds
The horizontal velocity of the diver = 23 meters / 3.526 seconds
=6.522 meters / seconds
Thus, the horizontal velocity of the diver would be 6.522 meters/second.
