The answer to your question is C. <span> the Sun's strong gravitational field . This is correct because i took the test :D</span>
Air is the answer i do believe
Answer:
In our everyday life, the deltoids take on most of the work in rotating our arms, but besides that the deltoid muscle also allows us to carry objects at a safe distance from the body. It is also responsible from stopping a dislocation or injury to the humerus when we carry something heavy.
Answer: Wavespeed (V) = Frequency F x wavelength λ (V = F λ)
Explanation:
The wavespeed is the distance covered by a wave in one second. It is measured in metre per second, and represented by the symbol V. It is directly proportional to the wavelength and frequency
i.e Velocity (V) = Frequency F x wavelength λ
V = F λ
For instance:
Assume wavelength (λ)= 20 m
Frequency = 10 Hz.
To get the wavespeed, use the formula
V = F λ
V = 20 metres x 10 hertz
V = 200 metres per second
Thus, the wave travels at a speed of 200 metres per second
