Scientists have observed that the average sunspots have increased in the last 50 years. Which of these statements best describes an effect of this increase in sunspots? A) Earth's temperature has become cooler.
B) Earth's temperature has not changed over time.
C) Earth's temperature has become warmer.
D) Earth's temperature has reduced by fifty times.

Answers

Answer 1
Answer:

Answer:

Earth's temperature has become cooler

Explanation:

The number of sunspots, as you have learned, can indicate whether the sun is in a maximum-activity period or a minimum-activity period. Some scientists believe this can have an overall effect on the climate of Earth.

Answer 2
Answer: The right answer for the question that is being asked and shown above is that: "B) Earth's temperature has not changed over time." Scientists have observed that the average sunspots have increased in the last 50 years. The statement that best describes an effect of this increase in sunspots Earth's temperature has not changed over time.

Chanel has some cotton candy that came in a cloudy shape. She wants to make it more dense. Which describes the candy before and after Chanel manipulated it?

Answers

The candy before has undergone physical change after manipulation because it says that it will make the cotton candy denser. Making it denser probably doesn't have to change any chemical components of the candy.

If a car goes five times as fast how much more kinetic energy will it have?

Answers


For that answer, we should take a second to look at the formula for kinetic energy:

                Kinetic Energy of an object = (mass) x (speed)² .

The important thing to notice is that the KE is proportional to the square of
the speed. So if you multiply the speed by some number, the KE changes
by the square of that number.

Multiplying the speed of the car by 5 gives it (5)² = 25 times as much KE.


the care will have 25 times as much kinetic energy as before

A. Destructive interference
B. Diffraction subtraction
C. Diffraction gradient
D. Constructive interference

Answers

Answer: Constructive interference

Explanation: Just took the test

Final answer:

The diagram shows destructive interference between two waves, resulting in a smaller amplitude wave.

Explanation:

The type of wave interaction shown in the diagram is destructive interference.

In destructive interference, two waves combine and create a new wave with a smaller amplitude. This occurs when the crests of one wave align with the troughs of another wave, causing cancellation.

In the diagram, wave A and wave B are out of phase, meaning their crests and troughs do not align. When they combine, the resulting wave has a smaller amplitude than either individual wave, indicating destructive interference.
