At 25 C, the length of the glass is 50 cm. After heated, the final length of the glass is 50.9 cm. at 225C The coefficient of linear expansion α?

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?

Neurons are components of the nervous system of the body that transmit signals as electrical impulses travel along their length. these impulses propagate when charge suddenly rushes into and then out of a part of the neutron called an axon. measurements have shown that, during the inflow part of this cycle approximately 5.6x10^11 na per meter, each with a charge of e enter the axon. how many coulombs of charge enter a 1.10 cm length of axon during this process

Answer fast for how does the force exerted by two magnets change as the magnets are moved farther apart? the magnetic force increases. the magnetic force decreases. the magnetic force stays the same.
