Answer:
benefits
Diversifying energy supply and reducing dependence on imported fuels.
Creating economic development and jobs in manufacturing, installation, and more.
drawbacks
Large areas of landfill are required
Hydroelectric power is generated from flowing water, which turns turbines and generates electricity
Explanation:
Answer:
Explanation:
given,
speed of the pebble = 14 m/s
height of the building = 31 m
ignoring air resistance
a) horizontally
V_x = 14 m/s
time =
time =
times = 2.52 s
v_y = 9.8 x 2.52
v_y = 24.7 m/s
resultant velocity
=
= 28.39 m/s
b) vertically straight up
max height =
=
= 11.47 m
height covered = 31 + 11.47
= 42.47 m
velocity =
=
= 28.85 m/s
c) vertically down
v² = u² + 2as
v² = 2 × 9.8 × 31 +14²
v² = 803.6
v = 28.35 m/s
Because that's called friction. When to things collide it causes friction which makes them stop rolling>
Answer:
is the maximum safe load.
Explanation:
Given:
- diameter of the cylinder,
- thickness of the cylinder wall,
- maximum bearable stress,
Firstly we find that:
⇒ This is a thin cylinder.
<u>We know axial stress and hoop stress is given by</u>
⇒ Axial load will always be larger than the circumferential load under while other parameters are same.
<u>So we find the load in case of axial stress:</u>
is the maximum safe load.
Answer:
I THINK it would be False.
