The crest of the wave has traveled 415 cm in 11.7s. then the crest should have travelled 415/11.7 cm in one second i.e. 35.47cm. Then the crest should have travelled 26*35.47 cm in 26 seconds i.e. 922.2cm which has 46 vibrations in it.
so for length of each vibration (Wavelength) is 20 cm
Answer:
B. Ball Y will travel at a speed less than 5 m/s in the opposite direction of travel as before the collision.
Explanation:
Impulse created by ball Y on ball X = 40 x 1/6 Ns
Ball X will also create impulse 40 / 6 on ball Y .
impulse = change in momentum .
impulse in Y = change in momentum in Y .
Initial momentum of Y = .5 x 5 = 2.5
Let final velocity of Y after collision be v in opposite direction .
change in momentum of Y = v - (-2.5 )
so,
v + 2.5 = 40 / 6 = 6.67
v = 4.17 m / s .
Option B is correct .
B. Ball Y will travel at a speed less than 5 m/s in the opposite direction of travel as before the collision.
Answer:
temperature is the degree or intensity of heat present in a substance or object.
Answer:
hello the options to your question is missing below are the options
culture
heredity
physical environment
social environment
answer : social environment
Explanation:
Claire ability to lose weight due to the encouragement and support of her friends shows that she was ability to achieve her goal due to her social circle ( friends ). therefore the face time that helped her lose weight is her social environment and not culture nor any other option as mentioned above.
social environments help/play a vital role in individual's life a lot as long as every human being is a social being
