Answer:
5.672/s^2 is his acceleration
Explanation:
1 minute is equal to 60 seconds. Take that and divide 340.3 by that.
Answer:
Volume of an object (L): blue 105.00, yellow 105.00, green 102.50, red 101.25
Density of an object (kg/L) Mass / Volume: blue 1, yellow 1, green 1.014, red .992
Sink or Float: blue sink, yellow sink, green float, red float
hope this helps
The power equals energy divided by the time
P=E/t
P=1200/60
P=20W
Hope you get it!
Answer:
A.
Explanation:
Earth is composed of different layers and one layer moves over another due to differences in the densities.
According to the physics of density, a substance having less density floats over a higher density substance. The oceanic crust has more density than the continental crust that is why continental crust float over oceanic crust.
So in the given example, plate B is moving below the plate A, it means plate B is more dense than plate A because plate B is composed of oceanic crust
. <u>For example : continents float over the asthenosphere (a layer below the lithosphere).</u>
Hence, the correct answer is "A
".
Answer:
A. the internal energy stays the same
Explanation:
From the first law of thermodynamics, "energy can neither be created nor destroyed but can be transformed from one form to another.
Based on this first law of thermodynamic, the new internal energy of the gas is the same as the internal energy of the original system.
Therefore, when the partition separating the two halves of the box is removed and the system reaches equilibrium again, the internal energy stays the same.
