Answer:
10 m
Explanation:
Weight = 10 N
mg = 10
m = 10 / 10 = 1 kg
g = 10 m/s^2
Initial mechanical energy = 40 J
Final mechanical energy = 140 J
change in total energy = 140 J – 40 J = 100 J
At the maximum vertical height, the velocity = 0 m/s
So,it has only potential energy at maximum height
P = m x g x h
100 = 1 x 10 x h
h = 10 m
Answer:
Breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
Explanation:
Take action on climate change has a positive effect on health of organisms and environment.
<h3>How and why to take action on climate change?</h3>
Spread awareness and encourage friends, family and co-workers to reduce carbon pollution, reduce burning of fossil fuels by using electrical vehicle and devices. Always buy sustainable products and avoid the use of plastics.
We have to take action on climate change because it improved health, maintain the population of organism, and reduced inequality. So we can conclude that take action on climate change has a positive effect on health of organisms and environment.

Answer:
C
Explanation:
The mechanical advantage is always less than 1 because the force needed to move an object is always greater than the weight of the object.
Answer:
No
Explanation:
Recall that the hierarchy of wavelength color from minimum wavelength to maximum wavelength is:
and
As a result, blue light has a higher energy level than green and red light.
As a result, the surface glows due to the blue LED. The green LED, on the other hand, would not allow the surface to glow as much as the red LED, which has a lower energy level when compared to the green light. As a result, the red LED would not allow the surface to glow as well.
