Answer:
A flat, horizontal line
Explanation:
A flat, horizontal line indicates a phase change.
The temperature does not increase because the added heat goes into converting one phase into another.
A is wrong. A downward-sloping line indicates that the temperature is decreasing with time.
C is wrong. An upward-sloping line indicates that the temperature is increasing with time.
Answer:
Normal force = 8.75 N
Explanation:
given,
frictional force between the steel spatula and the Teflon frying pan=0.350 N
coefficient of friction between material =0.04
normal force = ?
using formula,
Frictional force = coefficient of friction × normal force
Normal force = 8.75 N
Answer:
The most common of these is carbon 12, 13, 14. All of these isotopes have the same atomic number but different mass numbers. Carbon has the atomic number of 6 which means that all isotopes have the same proton number. However, the number of neutrons is different, thus giving different mass numbers.
Answer:
4 m/s
Explanation:
KE =
Velocity of balloon will be 4 m/s.

I think the correct answer from the choices listed above is option C. As an object sinks in a fluid, the buoyant force increases before it is submerged and as the object is submerged the buoyant force stays the same. This can be explained by Archimedes principle.<span />
