<span>When temperature increases, particles in an object speed up, which means an increase in thermal energy. Since the particles are moving more now, the potential energy decreases, therefore kinetic energy increases.
Overall, when temp goes up, thermal energy goes up, which leads to an increase in kinetic energy.</span>
Answer:
Speed of wave 54 ms⁻¹.
Explanation:
Given data:
Frequency of wave = 60 Hz
Wavelength of wave = 0.90 m
Speed = ?
Solution:
Formula
speed = wavelength × frequency
Now we will put the values in formula.
v = f × λ
Hz = s⁻¹
v = 60 s⁻¹ × 0.90 m
v = 54 m s⁻¹

Explanation: These are the only ones I know
Answer:
1. e m fmax = 0.00598 Volt
2. Imax = 0.000854 Amp
Explanation:
1. Find the maximum induced emf.
e m fmax =
Given that e m fmax = N*A*B*w
N = 1
A = 2 cm^2 = 0.0002 m^2
f = 143 rotation per minute = 143/min
f = (143/min) * (1 min/60 sec) = 2.38/sec
w = 2Πf = 2 * Π * 2.38 = 14.95 rad/sec
B = 2T
e m fmax = N*A*B*w
e m fmax = 1 * 0.0002 * 2 * 14.95
e m fmax = 0.00598 Volt.
2. Find the maximum current through the bulb.
Imax = e m fmax / R
Where R is the total resistance in the circuit is 7 Ω.
Imax = 0.00598/7 = 0.000854 Amp.
Imax = 0.000854 Amp
