Answer:
its electrons
Explanation:
only electrons stays outside the nucleus unlike protons and neutrons and it has little to no mass
Actually yes because my sis got a bruse in her body!
charge = current * time
q = 15 * 300 [5 min = 300 sec ]
q = 4500 C
Answer:
Distance,
Explanation:
It is given that,
Charge,
Area of the parallel plate capacitor,
We need to find the distance between the plates. Let it is equal to d. The capacitance of the parallel plates capacitor is given by :
k = relative permittivity, for air k = 1
So, the distance between plates is . Hence, this is the required solution.
The Kinetic Energy (KE) is calculated using the formula:
KE = 0.5 m v^2
Where,
m = mass of bare helium nucleus = 6.64 ✕ 10^−27 kg
v = velocity = 0.018 c = 0.018 * 3 ✕ 10^8 m / s^2 = 5.4 ✕ 10^6
m / s^2
Calculating:
KE = 0.5 (6.64 ✕ 10^−27
kg) (5.4 ✕ 10^6 m / s^2)^2
KE = 9.68✕<span> 10^−14
