Two tanks of gas, one of hydrogen, h2, and one ofhelium, he, contain equal numbers of moles of gas. thegram-molecular mass of he is twice that of h2. bothtanks of gas are at the same temperature, 293 k. which statement(s)below is(are) correct when we ignore vibrational motion?

the totalinternal energy of the hydrogen is the same as that of thehelium.

the totalinternal energy of the hydrogen is 1.4 times that of thehelium.

the totalinternal energy of the helium is 1.4 times that of thehydrogen.

the totalinternal energy of the hydrogen is 1.67 times that of thehelium.

the totalinternal energy of the helium is 1.67 times that of thehydrogen.

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
