Protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge).

Performing work on the system
Answer:
the maximum angular speed (in radians per second) of a Blu-ray disc as it rotates is 57.6 m/s
Explanation:
Given information:
diameter of the disc, d = 11 cm, r = 5.5 cm = 0.055 m
angular speed ω = 10000 rev/min = (10000 rev/min)(2π rad/rev)(1/60 min/s)
= 1000π/3 rad/s
to calculate the maximum angular speed we can use the following formula
ω = v/r
v = ωr
= (1000π/3)(0.055)
= 57.6 m/s
A)mass of object, since density =mass/volume
Given that,
Pressure = 425 Kpa
Pressure in millimeter of mercury = ?
Since, we know that,
1 Kpa = 7.5 millimeter of mercury
425 Kpa = 425 *7.5 millimeter of mercury
425 Kpa = 3187.76 millimeter of mercury.
The pressure of container filled with oxygen is 3187.76 millimeter of mercury.
