Is energy made or lost over time
Ann [662]

Well basically in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed, it can only be transformed or transferred from one form to another.


Hope this helps (:

If the flea jumps straight up, how high will it go? (Ignore air resistance for this problem; in reality, air resistance plays a
Savatey [412]

Answer:

The flea will reach to a height of 5.2 cm.

Explanation:

Let us assume it is given that, a flea reaches a takeoff speed of 1.0 m/s over a distance of 0.50 mm.

Initial speed, u = 1 m/s

Initial distance, x = 0.5 mm

We need to find the height reached by the flea. Using third equation of motion to find it.

At maximum height, its final speed, v = 0

v^2-u^2=2ah

Here, a = -g

-u^2=-2g(h-x)\\\\1^2=2\times 9.8\times (h-0.5\times 10^{-3})\\\\h=0.052\ m

or

h = 5.2 cm

So, the flea will reach to a height of 5.2 cm.
