Answer:
<h2>The answer is 9 W</h2>
Explanation:
The power used by an object can be found by using the formula
w is the workdone
t is time taken
From the question we have
We have the final answer as
<h3>9 W</h3>
Hope this helps you
This officer would be describing it's "acceleration". When someone is talking about how fast something or someone is going in this or this amount of seconds or minutes, this shows us that this person is reffering to this.
It's False. Because it's electromagnet NOT circuit. I'd go with False if I were youSorry if you get it wrong. Hope this helps.
Explanation:
Let's solve the problem by using conservation of momentum:
m1 u1 + m2 u2 = m1 v1 + m2 v2
where:
m1 = 3.5 g is the mass of the blue marble
m2= 1.2 g is the mass of the red marble
u1 = 15 cm/s is the initial velocity of the blue marble
u2 = 3.5 cm/s is the initial velocity of the red marble
v1 = 5.5 cm/s is the final velocity of the blue marble
We can find the final velocity of the red marble by re-arranging the equation and solving for v2 :
v2 = 1/m²(m1 u1 + m2 u2 - m1 v1)=
=1/1.2(3.5×15+1.2×3.5−3.5×5.5 )=31cm/s
