Answer:
500 joule
Explanation:
given,
mass(m)= 5kg
height(h)= 10m
acceleration due to gravity(g)= 10m/s^2
potential energy =?
We know that,
potential energy = mgh
= 5×10×10
= 500 joule
Answer:
Explanation:
Mass doesn't matter here because when something is falling, gravity plays fairly; an elephant falls at the same rate of acceleration as does a feather. What DOES matter is everything pertinent to the y-dimension of free-fall:
a = -9.8 m/s/s
v₀ = 0 (since the ball was held before it was dropped)
v = ??
Δx = -8 m (negative because the ball drops this far below the point from which it was released).
Putting all this together in one equation:
v² = v₀² + 2aΔx and filling in this equation:
v² = (0)² + 2(-9.8)(-8) and
v² = 156.8 so
v = 12.5 which rounds to 13 if you're using 2 sig figs, and rounds to 10 if you're only using 1 (which you should be, according to the way the numbers have been given in this problem)
1 is the body cell and 2 is the gamete. he reason is because the 1st one consists of more chromosomes than the second. a gamete will only consist of 23 while a body cell will consist of 46
0.1 J of elastic potential energy will be stored by the spring when it gets compressed by 0.2 m if it has the spring constant of 5 N/m.
Elastic potential energy can be defined as the potential energy stored by the spring when it is stretched or compressed.
- Amount of energy stored in the elastic material or spring is directly proportional to the amount of compression or elongation.
- It is represented by U.
- Mathematically, U =
; k is the spring constant and x is the compression or expansion suffered by the spring
According to the question.
Compression in the spring, x = 0.2 m
Spring constant, k = 5 n/m
Elastic potential Energy, U = 
U = 0.1 J
0.1 J of elastic potential energy will be stored by the spring.

Answer:
If the ball were thrown from the ground or even landed at an equal height (40m here), then yes, the time would be a 1:1 ratio of flight to fall.
But the ball is thrown from a height of 40m, so it will take longer to hit the ground.
For example, while it may take, say, 3 seconds to go up to its max height and 3 seconds to reach it's original height again, it may take 4 more seconds to finally reach the ground.
