Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.

A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other. The truck parked overnight in a place where energy transferred out of the substance. In the morning, the substance was a gas. How were the molecules moving in the morning?
Answer:
The gases will be together since they do not possess kinetic energy
Explanation:
let us use the kinetic theory of matter to explain the condition of the gas in the morning.
During the day, the atmosphere can be very hot so the gases tend to be in constant random motion, hence they will move away from themselves because they possess kinetic energy.
In the morning the temperature of the atmosphere is relatively low and the vehicle is not in motion, hence the gases will move together because they no longer possess kinetic energy anymore

Solar radiation, or insolation, is the “fuel” of all solar energy systems. The performance of solar photovoltaic systems which generate electricity and solar thermal systems which produce hot water all depend on the availability and intensity of solar radiation.
Insecticides can pollute the topsoil.
True or false ?
Answer:
True
Explanation:
Some insecticides when applied may persist for longer periods and that is very harmful because the soil is degraded and living organisms in the soil may be harmed leading to soil erosion. Then the soil will lose its fertility.

If a P-Wave took 5 minutes to reach a seismic
station and the earthquake began at 4:23:05, what
time did the P Wave reach the station?
Answer: 4:28:05
Explanation: if it takes 5 minutes to reach a station, just add 5 to the amount of minutes you already have (23) to get 28. And the hour and seconds stay the same.

But you're supposed to observe before you can come up with a question that you would then answer through experimentation.
