Answer:

atomic number (Z)

Explanation:

The atomic number (Z) is equal to the number of protons in the nucleus. In a neutral atom, the number of protons is equal to the number of electrons. The mass number of an atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

DENIUS [597]

Answer:

1.5 m

Explanation:

Let the distance from the box to the pivot be c.

Let the distance from the pivot to the effort be y.

From the question given above, the following data were obtained:

Effort force (Fₑ) = 7 N

Force of resistance (Fᵣ) = 14 N

Distance from the box to the pivot (c) = 0.75 m

Distance from the pivot to the effort (y) =?

Clockwise moment = Fₑ × y

Anticlock wise moment = Fᵣ × c

Clockwise moment = Anticlock wise moment

Fₑ × y = Fᵣ × c

7 × y = 14 × 0.75

7 × y = 10.5

Divide both side by 7

y = 10.5 / 7

y = 1.5 m

Therefore, the distance from the pivot to the effort is 1.5 m

PLEASE HURRY!!!!<br>why does the temperature change?
svet-max [94.6K]
Wind, radiation, and the sun are all factors that change the temperature.

Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.
