Answer:
The correct option is B
Explanation:
Although, it is common knowledge that in an electric field, unlike charges attract and like charges repel. However, to build up an electric potential, a positive charge is brought close to another positive charge - this causes work done to be changed to electric potential energy and stored in the electric field.
It should however be noted that when a negative charge is moved away from a positive charge, the negative charge gains electric potential energy.
Answer:
jfonox
Explanation:
since impulse is the change in momentum given by
Impulse = Force x time = change in momentum
I = ft = mv-mu= m(v-u)= jfonox
since the object is initially at rest
u=0,
mv is the final momentum of the object
I =Ft = m(v - 0) = jfonox
mv= jfonox
this show that the final momentum of the object at rest is equal to the impulse received
if any of the mass m, final velocity v or the impact force and the duration of impact of the object is known then we can find or quantify the final momentum.
Your pendulum does a complete swing in 1.9 seconds. You want to SLOW IT DOWN so it takes 2.0 seconds.
Longer pendulums swing slower.
You need to <em>make your pendulum slightly longer</em>.
If your pendulum is hanging by a thread or a thin string, then its speed doesn't depend at all on the weight at the bottom. You can add weight or cut some off, and it won't change the speed a bit.
<span>(a) 0.0676 l
(b) 67.6 cc
So we've been told that 5.00 L of blood flows through the heart every minute and that the heart beats 74.0 times per minute. So that means that for every beat of the heart, 5.00 L / 74.0 = 0.067567568 L of blood flows through the heart. Rounding to 3 significant figures gives 0.0676 l. Converting from liters to cubic centimeters simply require a multiplication by 1000, so we have 67.6 cc of blood pumped per beat.</span>
Your answer lies in between Diagram 3 and Diagram 4. You would add the sum of the two vectors to get your resultant, in which your answer comes out to be Diagram 3. ♥
