Answer:
This is because the force of gravity is much less on the moon than on the earth, therefore the person wont be pulled down much and will jump higher
E) Biotechnology use can lead to an increase in soil erosion and pollution runoff through decreased pesticide use.
Explanation:
Biotechnology use cannot lead to an increase in soil erosion and pollution runoff through decreased pesticide use.
There is no relationship between biotechnology use and increase soil erosion and pollution run off.
Biotechnology involves the application of technology based on living things.

Answer:
i) 3.514 s, ii) 5.692 m/s
Explanation:
i) We can use Newton's second law of motion to find out how long does it take for the Eagle to touch down.
as the equation says for free-falling
h = ut +0.5gt^2
Here, h = 10 m, g = acceleration due to gravity = 1.62 m/s^2( on moon surface)
initial velocity u = 0
10 = 0.5×1.62t^2
t = 3.514 seconds
Therefore, it takes t = 3.514 seconds for the Eagle to touch down.
ii) use Newton's 1st equation of motion to calculate the velocity of the lunar module when it hits the surface of the moon
v = u + gt
v = 0+ 1.62×3.514
v= 5.692 m/s
first is gamma Ray's, last is d
<u>Answer:</u> The correct statement is combining baking soda and vinegar will cause a chemical change.
<u>Explanation:</u>
A chemical reaction is defined as the reaction in which two or more chemical substances react to form two or more different chemical substances
A new substance (product) is formed in a chemical reaction when the bonds between the reactants are broken so that the new bonds between the products can be formed.
A physical process is defined as the process in which the physical state of matter takes place. Like, in the process of vaporization, a liquid state changes to the gaseous state without changing the composition of species.
When baking soda (Sodium bicarbonate) is reacted with vinegar (acetic acid), it leads to the formation of sodium acetate, water, and carbon dioxide.
A new compound is getting formed in this process which is denoted by the chemical equation:
Hence, the correct statement is combining baking soda and vinegar will cause a chemical change.
