In semiconductors, you can change how easily electrons move through them. That is option 2.
<h3>What are semiconductors?</h3><h3 />
Semiconductors is defined as those substances that possess the characteristics of both metal and non metal.
Examples of semiconductors include the silicon, germanium, and gallium arsenide elements.
The semiconductors are able to conduct electricity through the presence of electrons and holes in them.
The movement of these electrons can be controlled through the addition of impurities to the semiconductor material.
Therefore, in semiconductors, you can change how easily electrons move through them.

Explanation:
Image result for The energy from the sun can be used in many different ways. Describe two examples of how humans use the energy from the sun in their everyday lives. Make sure that one of your examples includes an energy transformation and explain the form it takes after it is transformed.
Solar energy is transformed into other energy forms for our use on Earth – energy for food (chemical energy), electrical energy and heat energy. Energy from the Sun is transformed into chemical energy, which is passed along in a food chain. Without the Sun, there would be no life on Earth
Answer:
t = 6.63 s
Explanation:
Given that,
Initial velocity of the puck, u = 7.3 m/s
Deacceleration of the puck, a = -1.1 m/s²
Distance traveled, d = 5 m
We need to find the time the goalie have to stop the puck. Using equation of motion.
v = u +at
v = 0 (stops)
So,
So, the required time is 6.63 seconds.
I think the answer to your question is a galaxy.
