Time taken by each ion to travel the semicircular path through the magnetic field is 34 X 10⁻²⁶s.
<u>Explanation:</u>
Given:
Charge of oxygen ion, q = -2
Magnetic Field, B = 0.12 T
Mass of O₂ , m= 2.6 X 10⁻²⁶ Kg
Time, T = ?
We know,
Therefore,
T = 2 X 3.14 X 2.6 X 10⁻²⁶/ 2 X 0.12
T = 68 X 10⁻²⁶s
For semicircular orbit, Time taken would be T/2
T ₓ = 68 X 10⁻²⁶/2 s
T ₓ = 34 X 10⁻²⁶s
Therefore, time taken by each ion to travel the semicircular path through the magnetic field is 34 X 10⁻²⁶s.
Answer:
9.67 kg
Explanation:
If the gauge pressure is 43 atm, the absolute pressure is 44 atm
p1 = 44 atm = 4.46 MPa
If the gauge pressure is 29.4 atm, the absolute pressure is 30.4 atm
p2 = 30.4 atm = 3.08 MPa
The ideal gas state equation is
p * V = m * R * T
We can set two eqaution for these two times
p1* V1 = m1 * R * T1
p2* V2 = m2 * R * T2
SInce V1 = V2 and T1 = T2
p1 = m1 * R
p2 = m2 * R
Rearranging
R = p1 / m1
R = p2 / m2
Equating:
p1 / m1 = p2 / m2
m2 = m1 * p2 / p1
m2 = 14 * 3.08 / 4.46 = 9.67 kg
<h2>If the object is moving then it has kinetic energy</h2>
Force = change of momentum / time taken
Force = (90x3)/0.6
