electric current flows through the filament of a bulb, it generates heat, and so the bulb becomes hot". This property is named the heating effect of electric current. ... An electromagnet is formed due to the magnetic effect of electric current

Answer:
When “current is switched” on in a “room heater” it produces heat due to “the heating effect” of the electric current.
Explanation:
The “heating effect of electric current” is its ability to produce heat when passing through a conductor.
A heating element in a room heater is made up of metal, mostly nichrome, which is a “good conductor of electricity”.
The electrical energy from the current passing through the filament is converted to heat energy and thus produces heat.
Other instruments which produce heat through the “heating effect of current” are electric iron and kettle.
Answer:
Explanation:m1 = 2kg
m2= 3kg
Now,
T= (2m1 × m2 / m1 × m2 )g
= (2 ×2 ×3/ 2+3 )g
= 12/5 g
a = (m2 - m1 / m1+ m2) g
= (3-2/3+2)g
= g/5
