Answer:
I believe 0 N
Explanation:
100 to the left can be said to be -100
100 to the right can be said to be +100
+100 + -100 = 0
Answer:
gpe gained = 20J
Explanation:
gpe = mass * gravity * height
gpe = (200/1000) kg * 10 * 10
gpe = 20J
Answer: A.True
Explanation: simply put the magnitude of the speed is a function of Distance while the magnitude of velocity is a function of Displacement. Displacement is the average Distance moved in different directions which will be smaller in magnitude compared to the Total Distance used the calculating the magnitude of speed.
Answer: touch the pan to the burner
Explanation:
There are three modes of heat transfer:
conduction, convection and radiation.
For conduction, the heat transfers from a hot object to a cold object when the two are in contact.
For convection there is bulk motion of fluid occurs which transfers the heat.
For heat transfer by radiation, medium is not required.
Thus, to demonstrate conduction between pan and burner, the pan must touch the burner.
100 meters in 9.92 seconds,
=distance/time
=100m/9.92s
=10.0806 m/s
