So obviously the 20N pulls more than the 5N. Friction opposes direction of motion, so the 5N opposes the 20N and the two forces are against each other.
Net force would be in the direction of the 20N force: 20N - 5N = 15N.
Force = mass*acceleration
15 = (5)*acceleration
acceleration = 3m/s^2
answer:
6 ohms
Explanation:
if these two resistors are connected in series, the total resistance is the sum: 2+4 = 6 (ohms)
Answer:
Y = 3.39 x 10⁶ m
Explanation:
We will use Young's Double Slit formula here:

where,
Y = Fringe spacing = ?
λ = wavelength =
= 8 x 10⁵ m
L = screend distance = 4030 nm = 4.03 x 10⁻⁶ m
d = slit separation = 950 nm = 9.5 x 10⁻⁷ m
Therefore,

<u>Y = 3.39 x 10⁶ m</u>
From 200 BC to around 14 AD, Rome had conquered most of Western Europe, Greece and the Balkans. Also the Middle East, and North Africa.
