The idea that "students ' immune systems have declined due to the use of hand sanitizers " is a hypothesis.
The term hypothesis refers to an intelligent guess or idea often based which is subject to scientific investigation via experiments.
A hypothesis may be right or wrong. We can only prove a hypothesis by subjecting it to a series of rigorous experiments.
Thus Collette's idea is a hypothesis.

Answer:
Read the Explanation
Explanation:
First notice some physics; the mass of the ball (projectiles) is not germane. A 2 ton elephant launched at U = 28 m/s will go just as high, which is H = U^2/2g = 28^2/(2*9.8) = 40 meters.
To solve this problem it is necessary to express the term of the wavelength of continuous x-rays according to the Planck constant, the speed of light, the charge of the electron and the voltage. This definition is expressed mathematically as
Here,
h is Planck's constant
c is speed of light
e is charge of electron
V is the potential to which the electrons are accelerated.
From this definition we can see that the wavelength is independent of the mass of the target material. Therefore the wavelength will remain the same.
Answer:
Objects that are of the same size but made of different materials
Explanation:
The rate it takes the object to cool is equivalent to the rate of heat loss
The rate of heat loss is given by the equation:
dQ/dt = K(T-T₀)
Where T = Temperature of the hot surface
T₀ = Temperature of the surrounding
K = constant
Both K and the rate of heat loss depends on the:
- nature of the surface
- Area of the surface
- Material of the surface of the body
Since the student only wants to know how the material in which the object is made of affects change in temperature, it means only the materials must be varied while other factors such as area and the size of the objects are kept constant.
