Answer:
The pressure is
Explanation:
From the question we are told that
The gauge pressure at the mouth is
The radius of the column is
The speed of the liquid outside the body is
The area of the column is
The area inside the mouth
Generally according to continuity equation
=>
=>
=>
So
=>
=>
substituting values
Now the height of inside the mouth is
Now the height of the column is
Generally according to Bernoulli's equation
Now which is the density of water
is the gauge pressure of the atmosphere which is zero
So
Answer: C. the motion of a spacecraft under gravitational influence.
Explanation:
A is Metallurgy, B is Biology, C is astro-physics, I am not sure what D is, but it's safe to say it's not physics, E, micro-biology, and the study of radiation. C is the only one involving physics.
Answer:
Explanation:
The sun is made up of 6 parts. Namely:
- The core
- The radiation zone
- The convection zone
- The photosphere
- The chromosphere and
- The corona
The convection area is just above the radiation zone. As materials from the suns core are heated, they rise above the radiation zone towards the EDGE of the convection area then sinks back again into the radiative zone for more heat.
The radiative zone is 12.6 million Fahrenheit hot and is just above the core.
The core of the son is not solid but plasma whose motion is like gas. Its temperature stands at 48 million Fahrenheit

Answer:
B, B (decreases, a clockwise)
Explanation:
Finally, the switch on the electromagnet is reopened. The magnitude of the external magnetic flux through the wire loop <u>decreases</u>, and there is <u>a clockwise</u>, current induced in the loop (as seen from the left).
