Answer:
(A) 654.545 Kw
(B) ![2.885\times 10^5kw](https://tex.z-dn.net/?f=2.885%5Ctimes%2010%5E5kw)
Explanation:
We have given resistance of the toaster ![R_1=2.2\times 10^{-2}ohm=0.022ohm](https://tex.z-dn.net/?f=R_1%3D2.2%5Ctimes%2010%5E%7B-2%7Dohm%3D0.022ohm)
Resistance of nichrome heating element ![R_2=9.7ohm](https://tex.z-dn.net/?f=R_2%3D9.7ohm)
Both the resistances are connected in series so same current will flow through the circuit
Potential difference across the toaster V = 120 volt
So current ![i=\frac{120}{0.022}=5454.5454A](https://tex.z-dn.net/?f=i%3D%5Cfrac%7B120%7D%7B0.022%7D%3D5454.5454A)
(a) Power dissipated in toaster ![P=i^2R=5454.5454^2\times 0.022=654545.441W=654.545kw](https://tex.z-dn.net/?f=P%3Di%5E2R%3D5454.5454%5E2%5Ctimes%200.022%3D654545.441W%3D654.545kw)
(B) Power dissipated in heating element ![P=i^2R=5454.5454^2\times 9.7=2.885\times 10^8W=2.885\times 10^5kw](https://tex.z-dn.net/?f=P%3Di%5E2R%3D5454.5454%5E2%5Ctimes%209.7%3D2.885%5Ctimes%2010%5E8W%3D2.885%5Ctimes%2010%5E5kw)
Answer:There's an increase in it potential energy
Explanation:there is an increase in it potential energy
Answer:
59.4 N
Explanation:
The force exerted on a current-carrying wire due to a magnetic field perpendicular to the wire is given by
![F=ILB](https://tex.z-dn.net/?f=F%3DILB)
where
I is the current in the wire
L is the length of the wire
B is the strength of the magnetic field
Here in this problem, we model the strike as a current-carrying wire, so we have:
I = 49,500 A is the current
L = 1 m is the length (we want to find the force per each meter of length)
is the strength of the magnetic field
Therefore, the force on each meter of the current due to the magnetic field is:
![F=(49,500)(1)(12\cdot 10^{-4})=59.4 N](https://tex.z-dn.net/?f=F%3D%2849%2C500%29%281%29%2812%5Ccdot%2010%5E%7B-4%7D%29%3D59.4%20N)
Health and safety are two reasons
Answer:
Trenches are the deepest part of the oceans, narrow and long depressions on the sea floor. One good example is the Mariana Trench, the deepest part of the ocean
