Answer:
Conduction
Explanation:
"Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules."
The heat in your hand melts that chocolate, making it conduction.
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable 's effects on the experiment and can help rule out alternative explanations of the experimental results.
The air pushes the engine with an equal force in the opposite direction.
Whenever force is used there is an opposite yet equal affect.
Answer:
the second one is incorrect
Explanation:
I am smart and took the test
When we see the words "Which statement ... ", we know right away that there
will be a list of choices, and we're expected to select our answer from that list.
Strangely, the list of answer-choices for this question has been lost.
Similarly, when we see the words "The picture shows ... ", it's hard to fight
the impulse to look around. In the present situation, <em>that's</em> missing too.
If the diver is just standing there, then the reaction force provided by the cliff
against his feet must be exactly equal to his weight. If the vertical forces acting
on the soles of his feet were not balanced, then his feet would be accelerating
vertically.
His weight is (mass) x (gravity) =
(93 kg) x (9.8 m/s²) = <em>911.4 newtons</em> (about 205 pounds) .
That's also the strength of the upward reaction force provided by the cliff.
