An electric toaster takes in electrical energy from the power outlet and converts it into heat, very efficiently. If you want your toast to cook quickly, you need a toaster that radiates as much heat as possible each second onto your bread

A toaster converts electrical energy to heat (or thermal) energy.  A toaster is an electrical device used for making toasts. The process involves putting pieces of bread in the slots of a toaster and using electricity to heat them. The heat is provided by coils that heat up due to passage of electricity and we end up with toasted bread or simply, toast.

The procedure that makes stars sparkle is the same one that we have outfit for utilization as a weapon: atomic combination.

Stars begin as gigantic districts of gas, for the most part hydrogen. This gas will begin to contract, and it warms up. As it gets, its temperature rises. At the point when the warmth gets sufficiently high, it causes the individual hydrogen iotas to impact and consolidate into helium with the arrival of vitality. This is called fusion.

A battery can be modeled as a source of emf in series, with both a resistance of 10Ωand an inductive reactance of 5
Fiesta28 [93]

Answer:

Explanation:

For circuit in resonance , inductive and capacitive reactance should be equal. Since in the given circuit ,  these two are not equal, the circuit is not in resonance. It does not depend upon voltage provided.

option b is correct.

With this load, the  fraction of the average power, put out by the source of emf,  delivered to the load can be calculated as follows

Power delivered to resistor will be 2/3 rd of total power delivered by source because resistance has value twice that of reactance of capacitor.  So the correct option is .7

option D ) is correct.

1: A car traveling at 10 m acceleration uniformly at 2 m. Calculate its velocity after5 s.
s344n2d4d5 [400]

Answer:

20 m/s

Explanation:

v = u + at

v: final velocity

u: initial velocity

a: acceleration

t: time

v = 10 + 2(5)

v = 10 + 10

v = 20 m/s
