Answer:
1/2 amper
Explanation:
I=V/R.(Current=voltage/resistance)
Answer:
The term used when one objects heat transfers to another would be known as: Convection.
Explanation:
Convection: <em>"the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat."</em>
The article I skimmed over explains, <em>"The outside surface of the cup is obviously hot or warm to the touch. Heat is not carried away fast enough from the cup to make the temperature of the outside surface of the cup equal to room temperature. Clearly, the cooling of the hot water in the cup involves conduction of heat through the cup followed by convection of the hot air associated with the outside surface of the cup away from the surface of the cup."</em>
In short, when a warm or cold liquid in a glass is set onto a table (the table is room temperature), then the temperature of that liquid will transfer into the table, causing the liquid to be room temperature after a certain time.
I hope this makes sense to you! Have a great rest of your night!
Answer:
5 m/s 2
To
get the acceleration of a car, you need to know first the difference in the
change in speed of a car then divided by time of the change. This can be
expressed as acceleration =
(change in speed) divided by (time for the change). So 30 m/s minus 10 m/s is
equal to 20 m/s divided by 4 seconds and the quotient is 5 m/s2.
6b: impulse is change in momentum. Change in momentum p=m[v(final)-v(initial). Final velocity is zero and initial velocity is the one you calculated before impact: -15.7 since it’s going down. Now plug in numbers and you get 78.5 in the upward direction.
6c: change in momentum p=Ft. we already calculated change in momentum. So plug it into equation and solve for t. 78.5/655= 0.119 s
Apply the same idea for question 7. Hope this helped
hey,
I'm here to help
just multiply each mouse's velocity components
then,
add them all up to get x,y total
