Explanation:
A light bulb changes electrical energy into <em>heat energy and light energy .</em>
Answer:
19.1 secs
Explanation:
The first step is to calculate the velocity
= 17.4/47.6
= 0.37 m/s
Therefore the time taken for the person to reach the top can be calculated as follows
= 17.4/(0.37+0.541)
= 17.4 / 0.911
= 19.1 secs
Hence the time taken is 19.1 secs
Because glass is not a good heat conductor. What it means is that heat isn't transfered through its structure as quickly as it would with metal, for instance. Because heat can't penetrate glass as quickly, the contents stay at the same temperature for longer.
.Answer:
The value of the work done is 
.
Explanation:
When a charged particle having charge 
is moving through an electric field 
, the net force (
) on the charge is
and the work done (
) by the particle is
Given, 
.
Substitute the value of electric field in equation (1) and then substitute the result in equation (2).
![W &=& \int\limits^7_0 {q\dfrac{A_{0}}{x^{1/2}}} \, dx \\&=& qA_{0} \int\limits^7_0 {x^{-1/2}} \, dx \\&=& 2qA_{0}[x^{1/2}]_{0}^{7}\\&=& 5.29 qA_{0}](https://tex.z-dn.net/?f=W%20%26%3D%26%20%5Cint%5Climits%5E7_0%20%7Bq%5Cdfrac%7BA_%7B0%7D%7D%7Bx%5E%7B1%2F2%7D%7D%7D%20%5C%2C%20dx%20%5C%5C%26%3D%26%20qA_%7B0%7D%20%5Cint%5Climits%5E7_0%20%7Bx%5E%7B-1%2F2%7D%7D%20%5C%2C%20dx%20%5C%5C%26%3D%26%202qA_%7B0%7D%5Bx%5E%7B1%2F2%7D%5D_%7B0%7D%5E%7B7%7D%5C%5C%26%3D%26%205.29%20qA_%7B0%7D)
