Answer:
When the resistances are connected in the parallel the equivalent resistance will be always less than the value of the lowest resistance in the parallel circuit.
The equivalent resistance in the parallel circuit can be calculated using the following formula.
1/R=1/R1+1/R2+1/R3
1/R= 1/10+1/20+1/30
1/R=(6+3+2)/60
1/R=11/60
R=60/11
R=5.45 Ohms
Organic materials comes from living things while inorganic materials comes from non living things
Organic materials are those composed mainly of carbon they are derived from living things while inorganic materials are derived from non living things sucjh as rocks etc
<span>Examples of Newton's 2nd Law If you
use the same force to push a truck and push a car, the car will have
more acceleration than the truck, because the car has less mass. It is
easier to push an empty shopping cart than a full one, because the full
shopping cart has more mass than the empty one.</span>

Answer:
371.2 mm
Explanation:
The Balmer series of spectral lines is obtained from the formula
1/λ = R(1/2² -1/n²) where λ = wavelength, R = Rydberg's constant = 1.097 × 10⁷ m⁻¹
when n = 15
1/λ = 1.097 × 10⁷ m⁻¹(1/2² -1/15²)
= 1.097 × 10⁷ m⁻¹(1/4 -1/225)
= 1.097 × 10⁷ m⁻¹(0.25 - 0.0044)
= 1.097 × 10⁷ m⁻¹ 0.245556
= 2.693 10⁶ m⁻¹
So,
λ = 1/2.693 10⁶ m⁻¹
= 0.3712 10⁻⁶ m
= 371.2 mm
