Answer:
Resistance
Explanation:
Resistance is the measure of the opposition of current in a circuit.
Answer:
C.5
Explanation:
A number of electrons present in valence shell of penultimate Shell represents the group of elements.
For s block elements: no.of group=number of valence shell electron.
p block elements: no. of group= 2 + 10 + number of valence electrons.
d block elements: no. of group= number(n-1)d electrons + number of electrons in nth shell.
Here, the differential electron is in p orbital hence, it belongs to p block
No. of group= 2+ 10 + 3=15 i.e 15th group or VA group.
Answer:
A). An independent variable
Explanation:
The Independent variable is characterized itself as the variable that is controlled or manipulated by the experimenter to observe its direct impact on the dependent variable. It is a variable that is not dependent and can stand alone. For example, if a student aims to observe the impact of temperature on solubility of a substance(sugar/salt) in a liquid, the temperature will be the independent variable as any change in the temperature will directly affect the solubility power of the liquid. Thus, <u>option A</u> is the correct answer.
