Answer:
Average velocity is 3.93 cm/s
Root mean square velocity is 4.79 cm/s
Velocity peak to peak is 6.28 cm/s
Explanation:
Speed of 2 particles = 5.3 cm/s
Speed of 4 particles = 1.4 cm/s
Speed of 6 particles = 7.14 cm/s
Speed of 8 particles = 1.52 cm/s
Speed of 2 particles = 7.68 cm/s
Average velocity is 3.93 cm/s
Root mean square velocity is 4.79 cm/s
Velocity peak to peak is 6.28 cm/s
The answer is A) variable. The depression level is a value that varies with the respondents and may inform you about the relationship between depression and other variables, such as alcohol use or sleep habits. It is also likely a discrete variable, since the answer is probably an integer (1, 2, ... 10), rather than a continuous spectrum (virtually any number between 1 and 10).
According to the heliocentric theory, the sun is the center of everything in the universe.
Answer:
E = 2.5 x 10⁻¹⁴ J
Explanation:
given,
diameter = 1.33 x 10⁻¹⁴ m
mass = 6.64 x 10⁻²⁷ kg
wavelength is equal to diameter
de broglie wavelength equal to diameter
v = 7.5 x 10⁶ m/s
Kinetic energy is equal to
E = 2.5 x 10⁻¹⁴ J
Answer:
Reading a Graduated Cylinder
Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.....
hope it helps....
