Help fast A water heater operates at 240 V, and the resistance of its heating element is 12 How much current does it demand , and how much thermal energy will it produce in 30 minutes ?

  a water heater rated for 240 volt can be connected to 120 volt generator, and the volts at your home first, because that affects actual watt output of elements . When power drops, then light bulbs dim, and produces less wattage output. Ohms is a measure of resistance and heat affects resistance, so if you test this element.

Explanation:

I think that’s right? Not to sure

d) physical means can be used to separate the components of air.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
