The answer is 4 kg m/s
because p = m x v , 2 kg x 2m/s = 4 kg m/s
The acceleration due to gravity falls off as the inverse of the square of the distance from the center of the Earth. Thus the distance of interest is
1/(d/R)^2 = 0.785/9.8
d = R·√(9.8/0.785) ≈ R·3.53328
or R·2.53328 above the surface of the earth.
Wikipedia says the radius of the earth is 6371 km, so your distance is
(6371 km)·2.53328 ≈ 16,140 km

Answer:
force on electron will be equal to
Explanation:
We have given magnitude of electric field E = 600 N/C
Charge on electron
We have to find the electric force on the electron
Force in electric field is equal to , here q is charge and E is electric field
So force will be equal to
So force on electron will be equal to
The complete question is as follows: At 700 K, decomposes to carbon and chlorine. The Kp for the decomposition is 0.76.
Find the starting pressure of at this temperature that will produce a total pressure of 1.1 atm at equilibrium.
Answer: The starting pressure of is 0.79 atm.
Explanation:
The equation for decomposition of is as follows.
Let us assume that initial concentration of is 'a'. Hence, the initial and equilibrium concentrations will be as follows.
Initial: a 0 0
Equilibrium: (a - x) 0 2x
Total pressure = (a - x) + 2x = a + x
As it is given that the total pressure is 1.1 atm.
So, a + x = 1.1
a = 1.1 - x
Now, expression for equilibrium constant for this equation is as follows.
Hence, the value of 'a' is calculated as follows.
a + x = 1.1 atm
a = 1.1 atm - x
= 1.1 atm - 0.31 atm
= 0.79 atm
Thus, we can conclude that starting pressure of is 0.79 atm.
