How does lithiums position in the periodic table relate to its properties

1 answer:

3 0

Being in group one we know it has 1 valence electron, is highly reactive to halogens, and based on the fact it is in period 2 we know it has 2 energy levels, 1 being full. We know this because it applies to everything in group one except for the part about energy level which is based on period.

A series circuit is composed of two resistors:

WITCHER [35]

<h3>Answer:</h3>

1.3 Amps

<h3>Explanation:</h3>

<u>We are given;</u>

A circuit with resistors, R1 and R2

R1 = 7 Ω

R2 = 11 Ω

Voltage = 24 V

We are required to calculate the current in the circuit.

<h3>Step 1: We need to find the effective resistance.</h3>

When resistors are arranged in series, the effective resistance is calculated by;

Rt = R₁ + R₂ + R₃ + ..........Rₙ

Therefore;

Total resistance = 7 + 11

= 18 Ω

<h3>Step 2: Calculate the current in the circuit</h3>

From the ohm's law;

V = IR

Rearranging the formula;

I = V/R

Thus;

I = 24 V ÷ 18 Ω

= 1.333 Amps

= 1.3 Amps

Thus, the current in the circuit is 1.3 Amps

How is it technically correct to say that a car making a u-turn can have a constant speed but cannot have a constant velocity?

saw5 [17]

During the "U" part of the turn, the car would follow an approximately circular path, and if it's moving at a constant speed, it would have to accelerate toward the center of the circle in order to change its direction.
