<h3>No:1</h3>
The object is moving with constant or uniform acceleration and in average speed
<h3>No:-2</h3>
The object is de accelerating
<h3>No:-3</h3>
The object deaccelerated and came to rest so fast.
<h3>No:-4</h3>
The object moves slowly first then accelerated.
<h3>No:-5</h3>
The object accelerated at first so fast then move with constant acceleration then again accelerated .
Answer:
energy left over from the big bang
Explanation:
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)
