You should mention that sound waves are generated in identical conditions i.e the speed of sound is same in the two experiments.
In that case the ratio is
2v/2L1 : 3v/4L2 = 4L2 : 3L1 .
Answer:
Since Force is Mass * Acceleration, the equation would be:
5kg * 2m^2 = 10N
<em>(10N is less than 65N)</em>
Therefore, it would not be enough force for the bag to break.
Answer: The coefficient of kinetic friction is μ = 0.6
Explanation:
For an object of mass M, the weight is:
W = M*g
where g is the gravitational acceleration: g = 9.8m/s^2
And the friction force between this object and the surface can be written as:
F = W*μ
where μ is the coefficient of friction (kinetic if the object is moving, and static if the object is not moving, usually the static coefficient is larger)
In this case, the weight is:
W = 20N
And the friction force is:
F = 12N
Replacing these values in the equation for the friction force we get:
12N = 20N*μ
(12N/20N) = μ = 0.6
The coefficient of kinetic friction is μ = 0.6
Answer:
Yes. Anytime the velocity is constant, the acceleration is zero. For example, a car traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.

brainlest plz, i really need it
The answer to your question is "Yes". Great numbers of people ... chemists,
physicists, and common folks alike ... know what Uranium is.
=================================
Uranium is one of the 92 elements that are found to occur in nature.
In the Periodic Table of the Elements, it is Element #92 ... Its atoms
contain 92 protons in their nucleii.
