Answer:
84%
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
x = 10 m
t = Time taken
= 3.5 m/s (assumed, as it is not given)
We have the equation
From continuity equation we have
Fraction is given by
The fraction is 84%
Answer:
(a)
(b)
Explanation:
mass, m = 2.3 kg
vx = 40 m/s
vy = 75 m/s
(a) Angular momentum is given by
Where, p is the linear momentum and r is the position vector about which the angular momentum is calculated.
Here,
So, the angular momentum
(b) Here,
The experiments that claimed to demonstrate cold fusion were found
to have been faulty by others who reviewed them. Also, nobody else
was
able to reproduce the finding in other laboratories. In the world
of
Science, this pretty much says that the initial claims were unfounded.
Answer:
it would remain the same speed
Explanation: the rock isnt going down a hill or anything so therefore if gravity isnt pulling it down a slope then it would remain the same pace
Answer:
20,000, though, I'm not completely sure.
Explanation:
"Sound is generated along the length of the lightning channel as the atmosphere is heated by the electrical discharge to the order of 20,000 degrees C (3 times the temperature of the surface of the sun)."
