Answer: The energy delivered to the toaster is 264.490KJ
Explanation:
Here is the complete question:
The resistance of a bagel toaster is 14 ?. To prepare a bagel, the toaster is operated for one minute from a 120-V outlet. How much energy is delivered to the toaster?
Step-by-step explanation:
Please see attachment below
Based on the direction of propagation compared to direction of vibration, waves are classified into:
1- Transverse waves: The direction of propagation of the wave is perpendicular to the direction of vibration of the medium particles.
2- Longitudinal waves: The direction of propagation of the wave is the same as the direction of vibration of the medium particles.
For the question we have here, since the direction of the wave is the same as the direction of vibration of particles, therefore, this wave is a longitudinal wave
The volume of the room is the product of its dimensions:

Now, from the equation

where d is the density, m is the mass and V is the volume, we deduce

So, multiply the density and the volume to get the mass of air in the room.
Explanation:
Relation between electric field and charge density is as follows.
E = 
where,
= charge density
= permittivity of free space = 
So,
= 0
or, 
Now, formula to calculate the potential difference of two conductors is as follows.

It is given that,
d = 6.0 mm = 

Hence, we will calculate the magnitude of the electric potential differences between the two conductors as follows.

=
= 0.0271 volts
thus, we can conclude that value of the magnitude of the electric potential differences between the two conductors is 0.0271 volts.
