A runner runs 4875 ft in 6.85 minutes. what is the runners average speed in miles per hour?

Answer: small barrel gun

Explanation:

It is noted that short barrel guns have a higher muzzle velocity for bullets compared to longer barrel guns.

Acceleration is determined by the change in velocity with respect to time.

For short barrel guns, the bullet reaches its muzzle velocity more quickly, leading to greater acceleration than that of bullets from long barrel guns.

Transverse waves propagate in a direction that is at right angles to the movement of the particles (or the medium involved). Hence, the particles would be shifting from east to west, which is perpendicular to the north-south direction of the wave.

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.

Fatima could investigate two possible hypotheses: A cat's heart rate varies while napping. A cat's heart rate remains unchanged while napping.

-- The torque applied to the door is (force) x (distance from the hinge) = (5 N) x (0.8 m) = 4 N-m. -- Torque = (moment of inertia) x (angular acceleration) 4 N-m = (moment of inertia) x (2 /s²) Moment of inertia = (4 N-m) / (2 /s²) = (4 kg-m²/s²) / (2 /s²) = 2 kg-m². Keep in mind that the mass of the person pushing does not play a role; it is only the force applied perpendicularly to the door. It could even be a mosquito exerting enough force of 5 N (approximately 18 ounces).
