I think so it's a beta particles which is a high speed electrons
Answer:
18 L
Explanation:
Use ideal gas law:
PV = nRT
Find initial number of moles, but first convert to units that match the gas constant units.
(200,000 Pa) (0.025 m³) = n (8.314 Pa m³ / mol / K) (25 + 273.15 K)
n = 2.017 mol
At the new pressure and temperature:
(250,000 Pa) V = (2.017 mol) (8.314 Pa m³ / mol / K) (0 + 273.15 K)
V = 0.018 m³
V = 18 L
Answer:
The magnetic field will become 1.6 T.
Explanation:
Given;
initial length of the solenoid, L₁ = 10 cm
final length of the solenoid, L₂ = 25 cm
Magnetic field inside a solenoid is given by;
Therefore, the magnetic field will become 1.6 T.
Assuming the scooter is moving horizontally on a flat surface, then by Newton's second law, the vertical forces (the normal force and the scooter's weight) cancel out:
<em>n</em> - <em>w</em> = 0
<em>n</em> = <em>w</em>
<em>n</em> = (120 kg) <em>g</em> = 1176 N
(where <em>g</em> = 9.8 m/s²)
Then the friction force has a magnitude of
<em>f</em> = <em>µ</em> <em>n</em>
where <em>µ</em> is the coefficient of kinetic friction, so that
<em>f</em> = 0.4 (1176 N) = 470.4 N ≈ 470 N
