Answer: E = 
Explanation: The formulae for intensity of an electric field of a solid metal sphere relative to a point is given below
r
where 
, 
, r = 0.1m r = is the position vector of the charge.
it has been stated in the question that the charge is placed at the center thus it has no position vector.
Answer:
Explanation:
When you're driving and you increase the speed of your car, it influences the chances of being involved in a traffic collision because it reduces the amount of time to adjust before a collision happens, and increasing the speed also contribute to the intensity of collision. Hence, making it difficult for anyone to survive.
<h2>Frequency of trumpet wire = 445 Hz</h2>
Explanation:
The given frequency of tuning fork is 440 Hz . It produces 5 beats with trumpet wire . That means , the frequency of wire can be 440 ± 5
It can be either 445 or 435
Now the length of wire is increased , by which its frequency decreases . Because frequency is inversely proportional to length of wire .
If we decrease the frequency in 435 , the difference between tuning fork frequency and wire frequency will become greater than 5 even . So it cannot produce 3 beats with it .
If we decrease frequency from 445 , it can become 443 Hz . It gives 3 beat with the tuning fork as given .
Thus the initial frequency of wire is 445 Hz
Answer:
2500/240 will give the resistance to be 10.42
