Answer:
6.77 m/s
Explanation:
Acceleration = Force/mass;
The block is accelerated by 13/6.4 m/s^2 for 2.1s from an initial velocity of 2.5m/s.
Applying the equation of motion:
Vf=Vi + at
Where Vf is the final velocity, Vi is the initial velocity, a is the acceleration and t is the time for which the object accelerates.
<h3>Vf= 2.5 + ((13/6.4)*2.1);</h3>
For number one she is going to observe the contraction of the ballon
For number two she is going to observe the expansion of the ballon
Answer:
d
Explanation:
you have to divide by the square root and then use the factorial to multiply
Generators take mechanical and output energy. electric motors take the input of electricity.
Answer is: protons and neutrons in atomic nucleus.
Proton<span> is a </span>subatomic particle (p⁺ or p) <span>with a positive </span><span>electric charge.
</span>Neutron (n⁰ or n)<span> is a </span>subatomic particle <span>with no net </span>electric charge.
Protons and neutrons are nucleons.
The nuclear force is attractive force<span> between nucleons.</span>
