Answer:
Hypothesis
Explanation:
Refer to a trial solution to a problem as a hypothesis, often called an "educated guess" because it provides a suggested outcome based on the evidence.
Answer:
0.5m(v1)²
Explanation:
We know that work done on an object is equal to the change in the kinetic energy of that object. Hence,
W. D = ΔK. E.
ΔK. E. = K. E.(final) - K. E.(initial)
Initial Kinetic energy, K. E.(initial), is:
K. E.(initial) = 0 (the box was at West)
Final K. E., K. E.(final) is:
K. E.(final) = 0.5*m*(v1)²
Hence, work done on the box will be:
W. D. = 0.5m(v1)² - 0
W. D. = 0.5m(v1)²
Answer:
I think that the centre of mass is the point at which the distribution of mass is equal in all directions, and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions, and does depend on gravitational field
Answer:
Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.
