Explanation:
The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
Electric field lines are a pictorial way to represent the electric field of a charge which basically indicates the field's strength.
The electric field is strong when the lines are close together and weak when they are far away from each other.
The greater the strength of the charge, the greater will be the number of field lines.
Hence, electric field lines provide a picture of an electric field indicating a field’s strength.
The correct option is Electric field lines
Need a picture of the problem
Answer:
a. 5A
b. 39.60%
Explanation:
The computation is shown below:
a. The current does it draw is
= v ÷ R
= 110v ÷ 22
= 5A
b. Now the efficiency of the motor is
n = mgh ÷ vlt
= (10,000 × 9.8 × 8) ÷ (5 × 3600 × 110)
= 784000 J ÷ 1,980,000
= 39.60%
hence, the above formulas are applied & the same is relevant
