How does a foam-filled winter coat keep a person warm? it slows down the transfer of thermal energy from outside to inside the coat. it slows down the transfer of thermal energy from inside to outside the coat. it speeds up the transfer of thermal energy from outside to inside the coat. it speeds up the transfer of thermal energy from inside to outside the coat.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
