Momentum is conserved in a collision. Momentum is mass*velocity, so you can find your answer by calculating initial and final momentums and setting them equal to each other.
15kg * 3.50 m/s + 9kg * 2.35 m/s = 73.65 kg m/s
73.65 = 9 * 2.8 + 15x
solve for x
x= 3.23
The final velocity is 3.23 m/s
The sun's energy influences climate in various ways. For example the latitudes at the equator receive more energy from the sun and therefore have warmer temperatures, On the other hand the sun's energy influences precipitation in a climate by driving the water cycle which determines precipitation.The sun is what makes the water cycle take place. That is the sun provides energy or heat to the earth; the heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds ( precipitation), that in turn give us rain
Answer:
Pe is stored energy to do work Pe is stored in objects that are at rest
KE defined as the energy of motion
began to move
Not sure about the rest
hope this helps
Explanation:
Answer:
5 L
Explanation:
Ideal gas law:
PV = nRT
If P, n, and R are constant, then:
n₁R/P₁ = n₂R/P₂
Using ideal gas law, we can rewrite this as:
V₁/T₁ = V₂/T₂
This is known as Charles' law.
Plugging in values:
10 L / 546 K = V / 273 K
V = 5 L
<h2>Answer: Transpiration
</h2>
Vegetal transpiration is the loss of water in the form of vapor, in the plant through its different parts, especially its leaves.
In this process, soil water is absorbed by the roots of the plant and transported in liquid form to the leaves to be converted into water vapor, while a part is used in photosynthesis. That is why vegetal transpiration is considered a vital function in the photosynthesis process.
This is possible because the leaves have small pores that allow water to escape into the atmosphere in the form of vapor and absorb carbon dioxide. Then, most of the water in the plants is used in the process of transpiration and only a small percentage is retained in liquid state and used for its growth and storage.
