Explanation:
It is known that the value of free fall acceleration is g = 6.44 . And, the value of radius of Earth is
.
Let us assume that height of the satellite is h.
It is known that,
g =
where, r = (R + h)
Hence,
r =
r =
=
Now, formula for height of satellite above the Earth's surface is as follows.
h = r - R
=
=
Thus, we can conclude that the satellite is high above Earth's surface.
The height of the satellite moving in a circular orbit above the Earth's surface is the satellite is; 1.5 × 10⁶ m
The formula to find the height of the satellite above the earth's surface is; h = [√(GM/g)] - R
where;
G is gravitational constant = 6.67 × 10⁻¹¹ N.m²/kg²
M is mass of earth = 5.98 × 10²⁴ kg
g is free fall acceleration = 6.44 m/s²
R is radius of earth 6400000 m
Thus;
h = [√(6.67 × 10⁻¹¹ × 5.98 × 10²⁴/6.44)] - 6400000
h = 1.5 × 10⁶ m

Answer: Reactants
Explanation: Reactants are the initial substances that reacts to form products in a chemical reaction.
Answer: The value of the equilibrium constant is 0.00009.
Explanation:
Initial moles of = 0.15 mole
Volume of container = 10 L
Initial concentration of
Moles of at equilibrium= 0.03 mole
equilibrium concentration of [/tex]
The given balanced equilibrium reaction is,
Initial conc. 0.015 M 0 0
At eqm. conc. (0.015-2x) M (2x) M (x) M
The expression for equilibrium constant for this reaction will be,
we are given : 2x= 0.003 M
x= 0.0015 M
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is 0.00009.
Answer:
8.48 × 10²² atoms of Nitrogen
Explanation:
Calcium Carbonate is an ionic compound made up to Calcium (Ca²⁺) and Nitrate (NO₃⁻) ions. Also, the subscript 2 after the closed bracket after NO₃ specifies that there are two moles of NO₃⁻ in calcium nitrate compound. Hence, in total we can say that this compound contain,
1 atom of Calcium
2 atoms of Nitrogen
6 atoms of Oxygen
Therefore,
When,
1 molecule of Ca(NO₃)₂ contains = 2 atoms of Nitrogen
Then,
4.24 × 10²² molecules of Ca(NO₃)₂ will contain = X atoms of Nitrogen
Solving for X,
X = 2 atoms × 4.24 × 10²² molecule / 1 molecule
X = 8.48 × 10²² atoms of Nitrogen
The statistical power is influenced by the factors such as sample size, significance error, observed test value etc. Hence, the critical value level is the one not influencing the statistical power.
Statiscal power is an important factor necessary to draw out the conclusion about a data. There will be always risk of making errors. Statistical power is the probability of avoiding these kind of errors from the various stages of data collection and interpretation.
If there is no enough power for a statiscal data, there will be lee worth for time and money expenditure on the resources. The sample size is the minimum number of observations that are required to study the effect of a certain size with the given power level.
The significant error level and observed test value are all affecting the statiscal power in an experiment. However, critical value level is having no significant role on it. Hence option B is correct here.
