Answer:
The correct answer is -
B. The velocity would double (v = 2v).
C. The wavelength would be half (λ = λ/2).
Explanation:
A wave has a speed or velocity that is related to the wavelength of the wave and the frequency of the wave and this relationship can be represented by the following equation-
Wave velocity V = Wavelength (λ) * Frequency (f)
Frequency (f) = Velocity (V) / Wavelength(λ).
The frequency and wavelength are inversely proportional and frequency and velocity are directly proportional to each other.
So, if f = 2f then,
putting value in the formula,
2f = 2v/λ, which means, f = 2v and f = λ/2
when the frequency is doubled, the wavelength will be halved and velocity will be doubled.
This is a diagram from above, the air resistance is oppose to movement, the bird is moving forward given its force is bigger.
Gravity causes a falling object to fall 9.8 m/s faster every second it falls.
Kenny's book started out with no speed when it was dropped.
1.5 sec later, it was falling at (9.8 x 1.5) = 14.7 m/s .
During the fall, its average speed was 1/2(0 + 14.7) = 7.35 m/s .
Distance it covered = (average speed) x (time) =
(7.35 m/s) x (1.5 sec) = 11.025 m
The answer is D.) *Five*
The five factors include: Muscular strength, Muscular endurance, Cardiovascular endurance, flexibility, and body fat composition
Decreases
Explanation:
The force of attraction between two objects will decrease as the distance between them increases.
This is in compliance with newtons law of universal gravitation.
The force of attraction between the two bodies is a gravitational force.
According to newton's law of universal gravitation "the force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".
We see that from the last statement, the force of attraction between is inversely proportional to the square of the distances between them.
F ∞ 
r is the distance between them.
