Answer:
2
Explanation:
It is going through the air and is moving so that means that it has kinetic energy. But it is also going to go the down, which gives it potential energy.
Answer:
13.79800 centimeters

Bohr atomic model different from the plum-pudding model as the Plum pudding model did not encounter the concept of nucleus it simply says compares atom with a pudding in which electrons are spread around as rasins in a pudding while bohr explain atom that is having nucleus that serves as a centre of the atom , and there are electrons around nucleus that occupy certain energy levels.
A covalent bond (I’m assuming that’s what you mean)
If the EN difference is less than 1.7, it’s a covalent bond
Here, we are required to determine the pressure of the sample of gas trapped in the open-tube mercury manometer shown below if Atmospheric pressure is 767 mmHg and pressure head, h = 8.9 cmHg.
- The pressure of the sample of gas trapped in the open-tube mercury manometer is;. 856 mmHg
According to the question;
- The atmospheric pressure is 767 mmHg
- The gauge pressure is 8.9 cmHg = 89mmHg.
The absolute pressure, P(abs);
is given mathematically as;
Absolute pressure = Atmospheric pressure + gauge pressure.
P(abs) = P(atm) + P(gauge)
P(abs) = 767mmHg + 89mmHg.
P(abs) = 856 mmHg.
