Answer:
<h3>Ion beams and Electrochemical are two examples of direct current electricity.</h3>
Answer:
All kinds of waves have the same fundamental properties of reflection, refraction, diffraction, and interference, and all waves have a wavelength, frequency, speed, and amplitude.
Explanation:
Answer:
76.4m/s
Explanation:
Given parameter:
Time taken = 7.8sec
Unknown:
Speed after it dropped = ?
Solution:
To solve this problem, we use one of the kinematics equation:
V = U + gt
V is the final speed
U is the initial speed = 0m/s
g is the acceleration due to gravity
t is the time taken
V = 0 + 9.8 x 7.8 = 76.4m/s
Answer:
Explanation:
20.05 √Tk = 20.05 √355.8 = 378.196... ≈ 378 m/s
Answer:
The maximum emf induced in the ring
= (2.882 × 10⁻⁷) V
Explanation:
According to the law of electromagnetic induction, the emf induced in the ring is given by
E = N BA w sin wt
The maximum emf induced is
E = N BA w
B = 30.5 μT = (30.5 × 10⁻⁶) T
A = (πD²/4)
D = 1.75 cm = 0.0175 m
A = (π×0.0175²/4) = 0.000240625 m²
Nw = 2π × 6.25 = 39.29 rad/s
E = 30.5 × 10⁻⁶ × 0.000240625 × 39.29
E = (2.882 × 10⁻⁷) V
Hope this Helps!!!
