Answer: 18000 coulombs
Explanation:
Given that:
Current, I = 5.0A
Electric charge Q = ?
Time, T = 1 hour
(The SI unit of time is seconds. So, covert 1.0 hour to seconds)
If 1 hour = 60 minutes and 60 seconds = 1 minute
Then, 1.0 hour = (60 x 60)
= 3600 seconds
Since electric charge, Q = current x time
i.e Q = I x T
Q = 5.0 A x 3600 seconds
Q = 18000 coulombs
Thus, 18000 coulombs of charge flows through the lamp in this time.
The answer must be a mass x velocity
Answer:
Explanation:
Answer:
The slits are 246 and 62 wavelengths wide, respectively.
Explanation:
Given that there are two slits:
the largest slit = x1 = 0.16mm or 0.00016m wide
the smallest slit = x2 = 0.04mm or 0.00004m wide, and
the wavelength of laser light = λ = 650nm or 650 × 10˄—9m
(a) the largest slit is X wavelengths wide where X = x1/ λ
Therefore, X = 0.00016m/650 × 10˄—9m = 246 wavelengths
(b) the smallest slit is X1 wavelengths wide, where X1 = x2/ λ
Therefore, Y = 0.00004m/650 × 10˄—9m = 62 wavelengths
Answer:
a = 0.273 m/s²
Explanation:
I would assume that the rider starts at 0m/s.
a = average acceleration
v = final velocity = 3 m/s
v0 = initial velocity = 0 m/s
t = time = 11 s
a = (v-v0)/t
a = (3m/s - 0m/s) / 11s
a = 0.273 m/s²
I am not sure how many decimals I should round it to, so I just gave three. If your teacher has instructions on that, do so accordingly.
