find (a) magnitude of the electric field 0.5m from a 2.5 -μC point charge and (b) the magnitude and direction of the electrostatic force acting on an electron placed at that point.
The weekly demand function for a product Z sold by a given supermarket is 30, 000 units when its price was birr 2. A 10% rise in the price of product Z results in the weekly demand to fall by 2000 units. Then drive The demand function
Armstrong numbers between two intervals
Write a program to print all the Armstrong numbers in the given range
A to B(including A and B). An N-digit number is an Armstrong number if the number equals the sum of the Nth power of its digits.
Input
The first line has an integer
A. The second line has an integer B.
Output
Print all Armstrong numbers separated by a space.
If there are no Armstrong numbers in the given range, print
-1.
Explanation
For
A = 150 and B = 200
For example, if we take number 153, the sum of the cube of digits
1, 5, 3 is
13 + 53 + 33 = 153.
So, the output should be
153.
Sample Input 1
150
200
Sample Output 1
153
Sample Input 2
1
3
Sample Output 2
1 2 3
important: please tell me how can we print -1 if there is no armstrong number
Calculate the power delivered to each of the resistors shown in Figure below.
An L-R-C series circuit is constructed using 175 resistor, a 12.5 capacitor, and 8.00-mH inductor, all connected across an ac source having a variable frequency and voltage amplitude of 25.0 V.
At what angular frequency will the impedance be smallest, and what is the amplitude at this frequency?
At the angular frequency in part (a), what is the maximum current through the inductor?
At the angular frequency in part (a), find the potential difference across the ac source, the resistor, the capacitor, and the inductor at the instant that the current is equal to one-half inductor it greatest positive value
In part (c), how are the potential difference across the resistor, inductor and capacitor related to the potential difference across the source.

A current in a conductor produces a magnetic field that can be calculated using the Biot – Savart law. Because cur- rent is defined as the rate of flow of charge, what can you conclude about the magnetic field produced by stationary charges? What about that produced by moving charges?
Describe the change in the magnetic field in the interior of a solenoid carrying a steady current I (a) if the length of the solenoid is doubled but the number of turns remains the same and (b) if the number of turns is doubled but the length remains the same.
