Answer:
Explanation:
The answer is in the picture
The initial velocity of the potato is 54.41 m/s.
The given parameters:
- <em>Mass of the potato, m = 0.34 kg</em>
- <em>Mass of the cart, m = 5.0 kg </em>
- <em>Velocity of the recoil, u₂ = 3.7 m/s</em>
<em />
The initial velocity of the potato is calculated by applying the principle of conservation of energy as follows;
Thus, the initial velocity of the potato is 54.41 m/s.

Answer:
A negatively ionized lithium paste is a conductor.
Explanation:
A conductor is a material that conducts electricity. In other words, a conductor has little resistance to the movement of electric charge or electrons when an electric field is applied.
Insulating materials for electricity are those that offer a certain resistance to the movement of electrons or electric current. In other words, an electrical insulator is a material with a low capacity for conducting electricity.
The best conductors of electric current are metals due to the free electron clouds that favor the circulation of electric current through them.
So, <u><em>a negatively ionized lithium paste is a conductor. </em></u>
Answer:
Battery.
Explanation:
A battery is a device that stores chemical energy, and converts it to electricity. This is known as electrochemistry and the system that underpins a battery is called an electrochemical cell. A battery can be made up of one or several (like in Volta's original pile) electrochemical cells
Answer:
The answer is...
D ( Plants use molecules of carbon dioxide to make sugar molecules.)
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Have an awesome day friend! <3
