Answer:
a) v₀ = 39.83 v / s
, b) y = 111.94 m
Explanation:
a) Let's use the kinematic relations for this problem
v² = v₀² - 2 g y
The speed at the base of the cliff is 30 m / s, the height y = 31 m
v₀² = v² + 2 g y
v₀ =√ (30² + 2 9.8 31)
v₀ = 39.83 v / s
b) at the point of maximum height the speed is zero
0 = v₀² - 2 g (y –y0)
y = y₀ + v₀² / 2g
.y = 31 + 39.83²/2 9.8
y = 111.94 m
Science is a process that involves the collection of information and ideas supported by evidence. Pseudoscience on the other hand, is a process that involves the collection of information and ideas supported by belief or opinion.
The answer would be: Winter
The Southern hemisphere is tilted to the left, few degrees away from the sun. This condition will result in more(to maximum) exposure to the sunlight, lead to the summer. The condition is the opposite of the northern hemisphere where it has less area that exposed to sunlight, lead to winter.
Answer:

Explanation:
GIVEN DATA:
Charge 3 nC
Radius of ring is 10 cm
A point charge 1 nC
Distance of point charge is 2.5 m
We know that voltage is calculated as


V = 270 V
At x = 2.5m

r = 1.581 m

V(2) = 10.801 V
Work done is calculated as
W= q(dV)


translation: What is the period between crest and crest, if a
wave travels 85ms, if distance
is 4.5m. And what is its frequency.
