Answer:
(A) 654.545 Kw
(B)
Explanation:
We have given resistance of the toaster
Resistance of nichrome heating element
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
(a) Power dissipated in toaster
(B) Power dissipated in heating element
Answer:
The answer is B.
Explanation:
Since they are made up of soft tissues, they decompose become they become fossils.
Answer:
0.011 N-m
Explanation:
Given that
The mass of a solid cylinder, m = 30 kg
The radius of the cylinder, r = 0.18 m
The acceleration of the cylinder,
It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :
Where
I is the moment of inertia of the cylinder,
For cylinder,
So,
So, the required torque on the cylinder is 0.011 N-m.
Answer:
Traveling with a constant velocity means you're going at the same speed in the same direction continuously. If you have a constant velocity, this means you have zero acceleration. ... If you travel with a constant acceleration, your velocity is always changing, but it's changing by a consistent amount each second.
Answer:
4.5g/cm^3
Explanation:
Here, Mass(m)=67.5g
Volume(v)=15cm^3
Now, According to formula,
Density(p)=m/v
=67.5/15
=4.5g/cm^3
