Answer:
0.71ohms
Explanation:
AC and CB are in series hence the total resistance is 3+2=5ohms
AD and DB are in series hence the total resistance is 3+2=5ohms
These resistances are parallel to resistance AB
Let the equivalent resistance be R.
For resistances in parallel
Hence the total resistances are:
5//1//5
1/R =1/5 + 1/1 +1/5 = 1+5+1 /5 = 7/5
Hence the total resistance is R= 1/ 7/5 = 1×5/7= 5/7=0.71ohms
Answer:
y and length is directly relation
Explanation:
Given data
A single-slit diffraction pattern is formed on a distant scree
angles involved = small
to find out
what factor will the width of the central bright spot on the screen change
solution
we know that for single slit screen formula is
mass ƛ /area = sin θ and y/L = sinθ
so we can say mass ƛ /area = y/L
and y = mass length ƛ / area .................1
in equation 1 here we can see y and length is directly relation so we can say from equation 1 that the width of the central bright spot on the screen change if the distance from the slit to the screen is doubled
Answer:
The potential difference across the source is 30.45 V.
Explanation:
In this setup we have a voltage divider, we were given the voltage difference on one of the resistors, we know that the difference pottential from the source in this case is the sum of the voltage in each individual resistor, so we can use the following equation to solve this problem:
V_resistor5.4 = (V_source)*(R_5.4)/(R_5.4+R_8.3)
V_source = (V_resistor5.4)*(R_5.4+R_8.3)/(R_5.4)
V_source = (12)*(5.4+8.3)/5.4
V_source = (12)*(13.7)/5.4 = 30.45 V
he potential difference across the source is 30.45 V.
