Answer:
Second Newton's law
Explanation:
Second Newton's law states that the acceleration of an object is related to the mass of an object and the force applied to it by:
where
F is the net force applied to an object
m is the mass of the object
a is the acceleration
The equation can be rewritten also as
(1)
we see that the acceleration is directly proportional to the force applied, F, and inversely proportional to the mass of the object, m.
In this problem, the force applied to the two objects (refrigerator and dumbbell) is the same, so we must look at their mass. Their mass can be found starting from their weight, which we know:
- refrigerator:
- dumbbell:
The dumbbell has a smaller mass, therefore by looking at formula (1), we can see that it will have more acceleration, and this is why it will move faster.

The Mid Ocean Ridge.
It spans around 40,389 miles around the globe and is located in the western Atlantic Ocean Basin. Majority (90%) of this ocean range is underwater.
Hope this helps!
Cosmic ray visual phenomena, or "light flashes" (LF), are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. While LF may be the result of actual photons of visible light being sensed by the retina,[1] the LF discussed here could also pertain to phosphenes, which are sensations of light produced by the activation of neurons along the visual pathway.[2]
Astronauts have long reported the experience of seeing flashes while they are in space, even when their eyes are closed. Neil Armstrong and Buzz Aldrin both reported these flashes during the Apollo 11 mission, and similar reports during the Apollo 12 and 13 missions led to subsequent Apollo missions including experiments specifically looking at this strange phenomenon.
The correct answer is Hydrogen and Helium.
