Answer:
22%
Explanation:
Given parameters:
The amount of change = $0.22
Unknown
What percentage of a dollar the change represents = ?
Solution:
A dollar is made up of 100cents;
So;
$0.22 represents 22cents
Percentage of dollar this represents = 
x 100 = 22%
Answer:
a) the greatest charge will be on C3=3 mF
b) Voltage will be same across each capacitors
Explanation:
Given: C1 = 1 mF, C2 =2 mF, C3 = 3 mf and V= 9 volts
To Find: greatest charge Q=? and which capacitor has the greatest voltage=?
Solution:
a)
As the voltage across each will be same so (using Q = C V)
Q1 = 1 mF × V
Q2 = 2 mF × V
Q3 = 3 mF × V
so the greatest charge will be on C3=3 mF
b) Voltage will be same across each capacitors
Explanation:
The separation between the interference fringes on the screen increases because
the distance of the screen from the slit is increased. Therefore option (a) is correct.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory.
Therefore option (b) is incorrect.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory. Therefore option (c) is incorrect.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory. Therefore option (d) is incorrect.
The separation between the interference fringes on the screen increases because the distance of the screen from the slit is increased, which is contradictory.
Therefore option (e) is incorrect.
Answer: a. both reliable and valid
The parameters used to describe a particular trait or characteristic in a human behavior should be reliable and valid, in order to determine the response of the population with respect to a particular stimulus.
