Answer:
the color of the light after it has passed through the cellophane
Explanation:
Since in the given experiment, there is an impact of various colors of light on the cell i.e. photoelectric that should be measured. The photocell should be placed in a circuit when the current would passed. For every color that falls on the photocell, the value of the current that passed via the cell represent an idea.
In the given situation the color of light shows an independent variable and the dependent variable is clicks per minute or the current that passed through the cell
The displacement is 0 km . Pls mark me as the brainliest
Answer: 22.8 g
Explanation:
1) density = mass / volume ⇒ mass = density × volume
2) density of magnesium = 1.74 g/cm³ (from internet)
3) volume of a block = length × width × depth
volume of the magnesium block = 2.5cm × 3.5 cm × 1.5 cm = 13.125 cm³
4) mass of the magnesium block = 1.74 g/cm³ × 13.125 cm³ = 22.8375 g.
Rounding to 3 significant figures, mass = 22.8 g ← answer
D = M/V.... it can be thought of as
D = ♡ with a line through it
............
D = .0057 kg / .0235 L
= .2425531915 kg/L
= .24 kg/L
