c
A candle glows as it burns
d
A wind turbine produces power for ligh
Answers
The battery represents the chemical energy. This is converted into electricity, which is converted into light energy.
An energy transformation from chemical to electrical to light energy is that a flashlight uses a battery to operate and the correct option is option B.
What is transformation of energy?An energy transformation is the change of energy from one form to another.
Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
The Law of Conservation of Energy states that energy can neither be created nor destroyed.
Therefore, An energy transformation from chemical to electrical to light energy is that a flashlight uses a battery to operate and the correct option is option B.

Which is the correct formula for acceleration? I got acceleration = change in speed / time
To calculate the acceleration of an automobile, you must first subtract the final speed from the initial speed. True or false. I got true but i also kinda thimk false
Answers
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Explanation:
Answer:
∞∞∞∞∞∞║Δ║Hello Friend║Δ║∞∞∞∞∞∞Your answer should be:
1. Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.
If you’re not changing your speed and you’re not changing your direction, then you simply cannot be accelerating—no matter how fast you’re going. So, a jet moving with a constant velocity at 800 miles per hour along a straight line has zero acceleration, even though the jet is moving really fast, since the velocity isn’t changing. When the jet lands and quickly comes to a stop, it will have acceleration since it’s slowing down.
2. True (Because if you subtract the final speed to the initial speed, you can see how much acceleration you put on or took off.

Answer:
Light is a kind of energy called electromagnetic radiation. There are many different forms of electromagnetic radiation, such as radio waves, microwaves, ultraviolet rays, and X-rays. Each form is characterized by a different wavelength. For example, radio waves can be several miles long, while gamma rays are smaller than atoms. The light that we see — visible light — falls somewhere in the middle of this "electromagnetic spectrum.

This passage describes a chemical reaction. Read the passage. Then, follow the instructions below.
Buttermilk is a dairy product that contains lactic acid (C3H6O3). The lactic acid makes buttermilk a useful ingredient in pancakes. When buttermilk is added to pancake batter, lactic acid combines with baking soda (NaHCO3) to make carbon dioxide gas (CO2). This gas forms bubbles in the batter, causing the pancakes to rise and become fluffy as they cook.

A. a rotation
B. an equinox
C. a photoperiod
D. a revolution
Answers
The Earth moves in predictable patterns. One of these patterns causes approximately 12 hours of daylight and 12 hours of darkness during a 24-hour period in areas around the equator. This movement is referred to as rotation.
What is rotation?When a spherical, three-dimensional object rotates around an invisible line inside of its center, it is a relatively common type of rotation. This focal point is known as an axis. Basketballs in motion revolve around an axis. Axially rotating globes are used. The Earth itself has an axis of rotation.
The axis of the Earth is vertical, which means it moves up and down. (A rolling log, on the other hand, runs sideways and has a horizontal axis.) The North and South Poles are on opposite sides of the Earth's axis. The Earth moves in predictable patterns. One of these patterns causes approximately 12 hours of daylight and 12 hours of darkness during a 24-hour period in areas around the equator. This movement is referred to as rotation.
Therefore, the correct option is option A.
