The working equation to be used for this is written below:
E = kQ/d²
where
E is the electric field
k is a constant equal to 8.99 x 10⁹ N m²/C²
Q is the charge
d is the distance
E = (8.99 x 10⁹ N m²/C²)(17×10⁻⁹ C)/(0.05 m)²
E = 61,132 N/C
Answer:
20,000 Ns
Explanation:
mass of exhaust gases, m = 50 kg
velocity of exhaust gases, v = 400 m/s
The momentum of a body is defined as the measurement of motion of body. mathematically, it is defined as the product of mass off the body an its velocity.
change in momentum of rocket = final momentum - initial momentum
= m x v - 0
= 50 x 400
= 20,000 Ns

Answer:
The vapor pressure is 170.6 mmHg.
Explanation:
Given that,
Heat of vaporization = 16.69 kJ/mole
Temperature = 254.3
Pressure = 92.44 mmHg
Temperature = 275.7 K
We need to calculate the vapor pressure
Using relation pressure and temperature
Put the value into the relation
Hence, The vapor pressure is 170.6 mmHg.
