IV - paper clip amount
DV - amount it flies
Control - I don't know this one
Constant - the airplane and force used to throw the airplane
Answer:

Explanation:
The way that it will change is by level of liquid in the whatever you are using will rise. This is because of the density of water created by the melting process of ice has a lower amount than the density of liquid in the beaker.
Answer:
Erosion is the wearing away if land by forces such as water and wind. It has created things such as mountain peaks, valleys and coastlines.
The answer is B hope this helped
Answer:
υ = 5.62 x 10¹⁴ Hz
Explanation:
The process of of formation of photons takes place due to interaction of a particle with its anti-particle is called Annihilation of Matter. Here SPARTYON absorbs anti-SPARYTON to form 2 photons. Applying conservation of energy to the to this scenario, we get:
2(Energy of Each Photon) = Rest Mass Energy of SPARTYON + Rest Mass Energy of anti-SPARTYON

where,
υ = frequency of each photon = ?
m₀ = rest mass of SPARTYON = mass of anti-SPARTYON = 455*Mass of electron
m₀ = 455(9.1 x 10⁻³¹ kg) = 4.14 x 10⁻²⁸ kg
c = speed of light = 3 x 10⁸ m/s
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
Therefore, using these values in the equation, we get:

<u>υ = 5.62 x 10¹⁴ Hz</u>
