Check my answers: the voltage across a 10-ohm resistor carrying 3 amps must be? i got 30 volts-v=? , i=3 amps, r= 16 ohm. v= 30 amps * 10 ohm=30 volts
a 4-ohm resistor is connected in parallel with a 6 ohm resistor. what is the total resistance of this pair of resistors? i got 6.87 ohms
rt=r1+r2/r1+r2 = rt= 4 ohm+6ohm/4 ohm+6ohm= rt=.25+.167/.25+.167=6.87
how i got .25 and .167 its from the decimal 1/4=.25 and 1/6=.167
the power dissipated in a 4-ohm resistor carrying 3 amps is? i wasn't too sure about this one, but i got 12 watts this is how i did it: power=current * voltage, power= 4 ohm* 3 amps= 12 watts
what is a device that produces ac electricity? why does our power grid use ac electricity? (for the first part i got an alternator and for the second part i don't understand)

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
