Answer:
The current is 0.248 A
Explanation:
Given that,
Inductor
Resistance
Voltage = 15 volt
Time
We need to calculate the current
Using formula of current
Where, V = voltage
R = resistance
L = inductance
T = time
Put the value into the formula
Hence, The current is 0.248 A.
Answer:
λ=34.068pm
Explanation:
Wavelength λ=2dsinθ
λ=2(33.4pm)sin30.7
λ=2(33.4pm) * 0.510
λ=66.8* sin30.7
λ=66.8*0.510
λ=34.068pm
X-rays are usually produced by charged particles that are accelerating or decelerating such as a beam of electrons striking a metal plate in an X-ray tube.
