Help ya girl out pls :)

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

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.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests

the answer is the last option

explanation:

because in order to know what the molecule is you need to know how many atoms of each element are in the molecule.
