I dont think so. It also probably matters what type of str it is
Answer: The definition is a longitudinal wave is a wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave
Explanation:
Answer:
(a) Tangential velocity will be 38.648 m/sec
(b) Acceleration will be 
Explanation:
We have given radius r = 11.2 m
Angular speed 
(a) We have to find the tangential velocity
We know that tangential velocity is given by
(b) We know that acceleration is given by
Well, first off, mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Light energy is the only form of energy that we can actually see directly. It is formed through chemical, radiation, and mechanical means. Striking a match stick (mechanical energy) creates fire, which has a ton of heat energy, and produces light too, so the answer, is A. I hope i could help!
Answer:
distance = 6 m
Explanation:
- Distance is a scalar quantity (so, only magnitude, no direction), and it is calculated as the scalar sum of all the distances travelled by an object during its motion, regardless of the direction. So, in this problem, the distance covered by the pinecone is
d = 4 m + 2 m = 6 m
- Displacement is a vector quantity (magnitude+direction), and its magnitude is calculate as the distance in a straight line between the final position and the initial position of the object. In this case, the final position is 2 m west and the initial position is 0 m, so the displacement of the pinecone is
d = 2 m west - 0 m = 2 m west
So, a scalar quantity from this scenario is
distance = 6 m
