What is the average kinetic energy of a particle of air at standard conditions?

Estimate what Earth’s rotational acceleration would be in rad/s2 if the length of a day increased from 24 h to 48 h during the next 100 years.

An apparatus similar to the one used in the electric field mapping lab is used to find the electric field between two parallel conducting plates. The electric potential difference between the plates is 57.7 0.2 V and the distance spearating the plates is 8.3 0.1

The displacement of a simple harmonic wave as a function of position x and time t is given by

A line charge with a variable linear charge density lambda(x) = cx stretches along the x-axis from x=0 to x=L. The total charge is Q.

Mary and her younger brother Alex decide to ride the carousel at the State Fair. Mary sits on one of the horses in the outer section at a distance of 2.0 m from the center. Alex decides to play it safe and chooses to sit

A proton moves through a region of space where there is a magnetic field B⃗ =(0.50i+0.40j)T and an electric field E⃗ =(2.8i−4.0j)×103V/m. At a given instant, the proton’s velocity is v⃗ =(6.1i+2.8j−4.8k)×103m/s.

A 2.0 m -long wire carries a current of 8.6 A and is immersed within a uniform magnetic field B⃗ . When this wire lies along the +x axis, a magnetic force F⃗ =(−2.0j)N acts on the wire, and when it lies on the +y
