Answer:
the helium nucleus’s final speed = ![1.55*10^7 \ m/s](https://tex.z-dn.net/?f=1.55%2A10%5E7%20%5C%20m%2Fs)
Explanation:
From the question; we are to calculate just only the helium nucleus’s final speed, in meters per second.
From the knowledge of Kinetic energy;
Kinetic energy K.E = ![\frac{1}{2} m_1v_1^2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20m_1v_1%5E2)
Making the velocity the subject of the formula from the above expression; we have:
![v_1 = (\frac{2K.E}{m_1})^{\frac{1}{2}](https://tex.z-dn.net/?f=v_1%20%3D%20%28%5Cfrac%7B2K.E%7D%7Bm_1%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7D)
where;
K.E = 8.00 × 10⁻¹³ J
m₁ = 6.68 × 10⁻²⁷ kg
![v_1 = (\frac{2*8.00*10^{-13}}{6.68*10^{-27}} )^{({\frac{1}{2})}](https://tex.z-dn.net/?f=v_1%20%3D%20%28%5Cfrac%7B2%2A8.00%2A10%5E%7B-13%7D%7D%7B6.68%2A10%5E%7B-27%7D%7D%20%29%5E%7B%28%7B%5Cfrac%7B1%7D%7B2%7D%29%7D)
![v_1 = 1.55*10^7\ m/s](https://tex.z-dn.net/?f=v_1%20%3D%201.55%2A10%5E7%5C%20m%2Fs)
Answer:
Quarks
Explanation:
Quarks, the smallest particles in the universe, are far smaller and operate at much higher energy levels than the protons and neutrons in which they are found.
Airports use ramps to connect the plane to the airport and towing trucks use ramps to get the vehicles on the truck
Weight = (mass) x (gravity)
= (75kg) x (9.8 m/s²)
= 735 kg-m/s²
= 735 newtons .
Answer:
mass*velocity=1.5*10^4 * 15
= 22.5*10^4
