Answer:
a) 1200 kN/m²
b) 1,200,000 kg/ms²
c) 1.2 × 10⁹ kg/km.s²
Explanation:
Given:
Pressure = 1200 kPa
a) 1 Pa = 1 N/m²
thus,
1000 N = 1 kN
1200 kPa = 1200 kN/m²
b) 1 Pa = 1 N/m² = 1 kg/ms²
Thus,
1200 kPa = 1200000 Pa
or
1200000 Pa = 1200000 × 1 kg/ms²
or
= 1,200,000 kg/ms²
c) 1 km = 1000 m
or
1 m = 0.001 Km
thus,
1,200,000 kg/ms² =
or
= 1.2 × 10⁹ kg/km.s²
Answer:
Explanation:
For a charged particle moving perpendicularly to a magnetic field, the magnitude of the force exerted on the particle is:
where
q is the magnitude of the charge of the particle
v is the velocity of the particle
B is the magnetic field strength
In this problem, we have
is the charge of the electron
is the velocity
is the magnetic field
Substituting into the formula, we find the force:
