A. A control group is given the experimental treatment.
Answer:
Spring's displacement, x = -0.04 meters.
Explanation:
Let the spring's displacement be x.
Given the following data;
Mass of each shrew, m = 2.0 g to kilograms = 2/1000 = 0.002 kg
Number of shrews, n = 49
Spring constant, k = 24 N/m
We know that acceleration due to gravity, g is equal to 9.8 m/s².
To find the spring's displacement;
At equilibrium position:
Fnet = Felastic + Fg = 0
But, Felastic = -kx
Total mass, Mt = nm
Fg = -Mt = -nmg
-kx -nmg = 0
Rearranging, we have;
kx = -nmg
Making x the subject of formula, we have;

Substituting into the formula, we have;


x = -0.04 m
Therefore, the spring's displacement is -0.04 meters.
Answer: The energy carried by an electromagnetic wave is proportional to the frequency of the wave.
Explanation:
Electromagnetic waves that are of higher energy than visible light (higher frequency, shorter wavelength) include ultraviolet light, X-rays, and gamma rays.
Answer:
Explanation:
insulators do not let their valance (out side elections) move about easily.
series circuits provide only 1 path for the electrons to travel.
Conductors allow their outside electrons to travel easily.
Imagine yourself in a wresting match. Your opponent only allows you to move if he lets you. That what resistance is.
Answers

2. Series circuits
3. conductors
4. resistance
In that order.
