An alarm clock has a current of 4.5 amps and a resistance of 3.2 ohms. what is the voltage in the circuit? a.1.4 volts b.0.71 volts c.14 volts d.46 volts

C. 14 volts

Explanation:

According to Ohm's law, the voltage is:  

  (1)

Where:

is the resistance of the clock

is the electric current that flows throgh the clock

Substituting these values in (1):

  (2)

connect the batteries in series and hope

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
