A particle that is smaller than an atom or a cluster of particles.
Answer: Gravitational force between the two masses does not depend on the medium separating two masses.
Answer:
160 W
Explanation:
Power is the ratio of work to time:
(1600 J)/(10 s) = 160 J/s = 160 W
Hypothesis: Enriched environments will have a positive effect and better performance of the experimental group of animals exposed to toys in comparison to the control group of animals in running in mazes.
Dependent Variable: Control Group
Independent Variable: Exposed/Experimental Group
Answer:
in projectile motion at maximum height v = 0
we can use the suvat equation to find v(initial)
since in this case v(final) is 0
t = 2.4 seconds
we need to find v(initial) or u
v = u+at
u = v- at
in this case a = g (gravity) = -9.81
u = 0 - (-9.81 * 2.4)
u = 9.81 * 2.4
the negatives become positive sin it’s a double negative ( - - = +)
