1) Roland has built a circuit, and is using a device called an ammeter to measure how quickly electrical current is flowing thro

zaharov [31]

Answer:

1) 3.9 %

2) 1,38 kg

3) 0.13 cubic meters

Explanation:

Part 1)

Calculated current = 0.180 amps

Measured current: 0.173 amps

percent error : $\frac{0.180 - 0.173}{0.180} \,100=3.9$ %

Part 2)

mass1 = 1,155 kg

mass2 = 0.22 kg

Addition; 1.155 + 0.22 = 1 375 kg which should be rounded to just two decimals according to the addition rules for uncertainties:

Answer : 1,38 kg

Part 3)

Volume = 0.885 x 0.20 x 0.75 cubic meters = 0.13275 cubic meters

Notice that the smallest number of significant figures among the set of dimension given is two. Therefore, our answer should be rounded to two significant figures. That is:

Volume = 0.13 cubic meters

Could someone please explain what makes up the electromagnetic spectrum? Thank you.

faust18 [17]

These types include gamma rays, x-rays, ultraviolet, infrared, microwaves and radio waves. Together with visible light, all these types of radiation make up what we call the electromagnetic spectrum - the complete spectrum of radiation.

Make the curvature radius 0.6 m, the refractive index 1.5, and the diameter 0.6 m. place the lamp so that the source of light is

vodka [1.7K]

We are given
r = 0.6 m
n = 1.5
D = 0.6 m, R1 = 30 cm
R2 = 120 cm

We are asked to get the focal length and the distance of the focal plane from the lens

We use the formula
1 / f = ( n - 1) (1/R1 - 1/R2)
Substituting and solving for f
1/ f = (1.5 - 1) (1/30 - 1/120)
f = 80 cm

The focal length is 80 cm and the distance of the focal plane from the lesn is 80 cm - 30 cm = 50 cm.<span />
