When light enters a lens, C) it is refracted.
Since it is bent when it enters a lens, it has to be refracted.
Answer:
cause it takes a lotof energy to melt
Explanation:
The grand canal was built to make easier the transportation of grains to the power center of north china.
<h3>How was the Grand Canal built?</h3>
The canal was built in order to connect the Yellow River in the north with the Yangtze River in the south. This canal is built for making easier the transportion of grain from the south to the centers of north China. The total length of the Grand Canal is 1,776 km.
So we can conclude that the grand canal was built to make easier the transportation of grains to the power center of north china.

(1) directed to the right
Explanation:
To the right of B, u(x) is a decreasing function & so its derivative is negative,this implies that the x component of the force on a particle at this position is positive,or that the force is directed towards right .Small deviations from equilibrium at point B causes a force to accelerate the particle away ,hence particle is in <u>unstable equilibrium.</u>
Explanation:
Given that,
Net force = 135.5 N
Mass = 26.7 kg
(a). We need to draw a free body diagram
A force is exerted on a object.
(b). We need to calculate the acceleration
Using formula of acceleration
(c). We need to draw the sketch a position vs. time graph for the object.
Using equation of motion
Put the value into the formula
(d). We need to draw the sketch a velocity vs. time graph for the object.
Using equation of motion
Put the value into the formula
(e). We need to calculate the distance travel in 8.82 s
Using equation of motion
Hence, This is the required solution.
