Answer:
Because Bricks don't reflect. but mirrors reflect due to their lustre nature.
Explanation:
Given that the design is not shown, for traditional nuclear reactors with control rods, the best way to meet an increased demand for energy would be to raise the control rods so that less neutrons are absorbed.
So, the most reasonable answer to the question is B.
It is the energy an object has because of its motion.
Answer:
6.65m/s
Explanation:
Using the equation of motion
S = ut + 1/2gt²
S is the height of fall
t is the time
u is the horizontal velocity
g is the acceleration due to gravity
Given
S = 300 + 50
S = 350m
t = 7.8seconds
g = 9.8m/s^2
Get S
S = 7.8u + 1/2(9.8)(7.8)²
S = 7.8u + 298.116
350 = 7.8u + 298.116
7.8u = 350 - 298.116
7.8u = 51.884
u = 51.884/7.8
u = 6.65m/s
Hence the rock's horizontal velocity was 6.65m/s
