To do that, you must pass electric current through a substance
that electrons have to spend energy to pass through.
The substance will be one that gets warm and dissipates heat
when electric current flows through it.
We'll say that the substance has "resistance", which we can measure.
The amount of heat that appears when current flows through it
will be (current²)·(resistance).
A few examples of things used for that purpose:
-- resistors
-- burners on electric stoves
-- coils of resistor-wire in a toaster
-- aquarium heater
-- electric clothes iron
-- electric coffee pot
-- blow-dryer
-- electric hair-curling iron
-- skinny tungsten wire in a light-bulb .
Answer:
a) 
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
a = Acceleration

Answer:
Corpus callosum
Explanation:
The corpus callosum is the tissue in the brain that helps in the connection between the right and left cerebral hemisphere.
The corpus callosum consists of about 200 million axons of thick nerve cells which helps in combining sensory and cognitive signals between the two hemispheres.
Almost everyone is born with this tissue because an absence of deficiency of it results in serious neurological problems such as difficulty in learning and other cognitive related diseases.
