What is the internal energy (to the nearest joule) of 10 moles of Oxygen at 100 K?

Answer: The result to the query is 0.25 ohms

Explanation:

R = u x/A.......1

where u represents the resistivity of the

rod, A is the cross-sectional area, and x denotes

the length of the rod.

Let R* represent the resistance across the adjacent sections of the rod.

Then, R* = u1/4.......2

By comparing equation 1 with equation 2, we find that

R* = 1/4

which equals 0.25 ohms.

The male skater reaches a velocity of 13.71 m/s. According to the principle of conservation of momentum, m1u1 = (m1 + m2)u2, where m1 signifies the mass of the male skater at 78.2 kg, m2 is the mass of the female partner at 48.5 kg, u1 is the male skater's resulting velocity from the push, and u2 is the velocity imparted to the female skater, which was 8.46 m/s. Through the formula, we find u1 = [(78.2 + 48.5) × 8.46] ÷ 78.2, which calculates to 1071.882 ÷ 78.2 resulting in u1 = 13.71 m/s.

Response:

d) In container A, the average kinetic energy per molecule exceeds that of container B.

e) Molecules in A exhibit a higher speed than those in B.

Reasoning:

Both containers are of identical size.

This indicates that the volume of each container is equal to V.

Temperature in container A is 50°C, which equals 323 K.

Temperature in container B is 10°C, equating to 283 K.

According to the ideal gas law:

P V = m R T

The quantities of gas mass are unspecified, making it impossible to determine which has a higher temperature or a greater number of molecules.

However, it is known that the average kinetic energy is directly related to the absolute temperature of a gas; thus, the kinetic energy in container A is greater due to its higher temperature. A higher kinetic energy implies increased molecular velocity.

Consequently, options d and e are accurate.

d) In container A, the average kinetic energy per molecule exceeds that of container B.

e) Molecules in A exhibit a higher speed than those in B.

The horizontal distance traveled by the bird is identified as x. Initially, the height of the bird is 25 meters, and the angle formed with the vertical is denoted as θ. d² = x² + y²; so, at x = 12 meters, we can make calculations to find y.

Answer:

Explanation:

To find the height of the beam where it strikes the clouds, apply the Pythagorean theorem using these formulas:

If:

Then:
