Aman pushes a sled across the snow, using a force of 300 n over a distance of 2 m. what is the kinetic energy of the sled after he pushes it? assume there is no friction.

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

This is the substance(s) formed in a chemical reaction.
