Answer:
Amplitude: 2cm
Period: 1/12 s
Wavelength: 10 cm
Speed: 120 cm/s
Explanation:
The amplitud is the vertical distance from the resting position to the crest or to the trough, and the vertical distance from a crest to a trough is two times the amplitude. Therefore the amplitud (A) is:
A= 4cm/2= 2cm
The period (T) is:
s
The wavelength is defined as the horizontal distance from a crest to the nearest crest or from a trough to the nearest trough. The distance from a crest to the nearest tough was given. Therefore two times that distance is the distance from a crest to the nearest crest.
The wavelenght (λ) is:
λ=(2)(5)=10cm
The speed (v) in a wave is given by:
v = λf
v=(10)(12)=120 cm/s
The average speed is 8 miles
Ek = 6KJ.
In physics, the kinetic energy of a body or object is the one that owns due to its movement and is given by the equation , where m is the mass of the object in kilograms and v is the velocity in m/s.
An object that it has a mass of 30 kilograms and moves with a velocity of 20m/s, its kinetic energy is given by:
Answer: 47.28
Explanation:
just times 5.91 by 8 your welcome please leave a heart and five star
A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Transformers are mainly used to increase or decrease voltage in power lines or electric power applications. So your answer would be D. transformer
