I’ll make Brainliest When a net force of 3 N is applied to a 0 75 kg cart the cart's velocity changes from 0.2 m/s to 18 m/s in 0.3s Suppose that by adding masses the total mass of the cart doubles the same force applied for the same amount of time what will the change in velocity be in m/s?plz don’t put the answer if you do not know ;(

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.

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?
