The control group is the independent variable and the experimental group is the dependent due to change during the experiment. The experimental group will usually rely on another variable in the experiment for change.
It wouldn't indicate the same source if the paint was from a different place. If the paint was the same brand and color it would be but if not then no
<u>Answer:</u>
The correct answer option is momentum.
<u>Explanation:</u>
Momentum is the product of an object's mass and velocity.
It is a term which describes the relationship between the mass of an object and the velocity of an object.
Momentum can be represented in the form of an equation as:
P = mv
where P is the momentum,
m is the mass of the object; and v is the velocity of that object.
Answer:
v = 8.4 m/s
Explanation:
The question ays, "A longitudinal wave has a frequency of 200 Hz and a wavelength of 4.2m. What is the speed of the wave?".
Frequency of a wave, f = 200 Hz
Wavelength = 4.2 cm = 0.042 m
We need to find the speed of the wave. The formula for the speed of a wave is given by :

So, the speed of the wave is equal to 8.4 m/s.
Answer:
A fuse and circuit breaker both serve to protect an overloaded electrical circuit by interrupting the continuity, or the flow of electricity. ... Fuses tend to be quicker to interrupt the flow of power, but must be replaced after they melt, while circuit breakers can usually simply be reset.
