Explanation:
Energy pyramid: is a model that shows the flow of energy from one feeding level to the next in an ecosystem. It compares the energy used by organisms at each trophic level.
Unit: kilocalories (kcal).
While Biomass pyramid is a statistical graph that shows the biomass present in a unit area of various trophic levels. It shows the relationship between biomass and trophic level. It quantifies the amount of biomass available in each trophic level of an energy community at a given time.
Unit: grams per square meter (g/m^2), or calories per square meter (K/m^2).
Answer:
Explanation:
Given
acceleration of rocket(a)
At h=1000 m rocket burn out



(b) time to reach v=100 m/s
v=u+at


(c)Rocket maximum altitude

here u=100 m/s
v=0



[tex]s=510.204
Therefore maximum altitude=510.204+1000=1510.204 m
Answer:

Explanation:
Given that,
Charge, 
Revolution = 7 rev
magnetic field, B = 45 mT
Time, t = 1.29 ms
We need to find the mass of the ion. Let m be the mass. The formula for the mass in terms of time period is given by :

So, the mass of the ion is equal to
.
The kind of heat necessary to transform sand into a liquid state (eventually becoming glass) is much hotter than any sunny day. To make sand melt, you need to heat it to roughly 1700°C (3090°F), which is approximately the same temperature a space shuttle reaches as it re-enters earth's atmosphere.
The mass difference is in between the two is equivalent to the binding energy of the nucleus .
<h3>What is meant by mass difference? </h3>
Δm be the mass difference is defined as the difference between the mass of the nucleus and the total mass of the individual nucleons that comprise it.
Binding energy is the energy required to split the nucleus of an atom into neutrons and protons, while mass defect is the difference between the predicted mass and the actual mass of the nucleus of an atom .
The mass difference is difference between the mass of nucleus and the Total mass of the individual nucleons that make it up.
∆m = final mass - initial mass.
