Many flashlights are powered by a stack of batteries that are slid into the end of the flashlight one after another. Suppose you
1 answer:
Answer:
The current through the bulb when the flashlight is turned on is 0.55 A.
Explanation:
Given that,
You have a flashlight that takes four ideal 1.5 V batteries, voltage of the flashlight, V = 6 V
The resistance of bulb, R = 11 ohms
We need to find the current through the bulb when the flashlight is turned on. As per Ohms's law :
V = IR
So, the current through the bulb when the flashlight is turned on is 0.55 A. Hence, this is the required solution.

λ = 451.7 nm
Explanation:
The expression for the constructive interference of the double diffraction experiment is
d sin θ = m λ
let's use trigonometry
tan θ = y / L
how the experiment occurs at very small angles
tan θ = sin θ / cos θ = sin θ
sin θ = y / L
we substitute
d y / L = m λ
λ =
let's calculate
λ =
λ = 4.51699 10⁻⁷ m
λ = 4.517 10⁻⁷ m (109 nm / 1m)
λ = 451.7 nm
Answer:
Acceleration,
Explanation:
Initial velocity of a particle in vector form, u = (-5i - 2j) m/s
Final velocity of particle in vector form, v = (-6i + 7j) m/s
Time taken, t = 8 seconds
We need to find the magnitude of acceleration vector. The changing of velocity w.r.t time is called acceleration of a particle. It is given by :
or
Hence, the value of acceleration vector is solved.
