when a hole is made at the bottom of the container then water will flow out of it
The speed of ejected water can be calculated by help of Bernuolli's equation and Equation of continuity.
By Bernoulli's equation we can write
Now by equation of continuity
from above equation we can say that speed at the top layer is almost negligible.
now again by equation of continuity
here we have
now speed is given by
B. accelerates in the direction of the force. this is because the force is now unbalanced, causing the object to move in that direction. it's like pushing a pen off the table. you applied force in that direction and since the pen doesn't have enough inertia to withstand your unbalanced force, it rolls off the table.
Answer:
metamorphic rock
Explanation:
Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.
Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.
- At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks.
- These changed rocks have different mineral facies that are different from those of the prolith.
Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.
Answer:
4. To the east
Explanation:
Friction forces always act in the opposite direction that an object tends to move in. In this case, when the truck accelerates to the east, the crate tends to move to the west due to inertia (the tendency for an object to remain at rest or at constant speed). In order to stop the crate from moving, there needs to be a friction force to the east.
Your pet must have current vaccinations that are required by the place (state, country, etc.) that it will be entering. Your pet would also need a health certificate that was done by a licensed veterinarian.
