Explanation:
to get density, simply divide the mass by the volume. Your equation would look like this; p=562/43
'P' represents density in this equation. Never forget to add your units!
Hope this helps!
Answer:
EXAMPLE:when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
:
Explanation:
this graph show the decrease in velocity with time
at time t=0 velocity is 40 m/sec
at time t=12sec velocity is decreases from 40 to 10 m/s
so the acceleration of the object at time=12 sec is
a=v/t
a=Δv/t
Δv=v1-v2=40-10=30 m/s
a=30/12=2.5 m/s^2
<span>The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases. hope this helps you!</span>
