The correct answer is:

Does the measurement include direction?

In fact, the basic difference between a scalar and a vector is that a scalar does not have a direction (it only has a magnitude), while a vector has both magnitude and direction. Therefore, if the answer to this question is "yes", it means the quantity is a vector, otherwise it is a scalar.

A spider of mass mm is swinging back and forth at the end of a strand of silk of length LL. During the spider's swing the strand

krok68 [10]

Answer:

The speed of the spider is v = (2g*L*(1-cosθ))^1/2

Explanation:

using the energy conservation equation we have to:

Ek1 + Ep1 = Ek2 + Ep2

where

Ek1 = kinetic energy = 0

Ep1 = potential energy = m*g*L*cosθ

Ek2 = (m*v^2)/2

Ep2 = m*g*L

Replacing, we have:

0 - m*g*L*cosθ = (m*v^2)/2 - m*g*L

(m*v^2)/2 = m*g*L*(1-cosθ)

v^2 = 2g*L*(1-cosθ)

v = (2g*L*(1-cosθ))^1/2

\. A mixture of gases con-tains oxygen, nitrogen, and water vapor. What physical process could you use to remove the water vapor

Eddi Din [679]

Answer:

Condensation.

Explanation:

The boiling point of water is much higher than that of either nitrogen or oxygen gas . So when the mixture is condensed to a temperature lower than

100°C , water vapor will come out first in the form of water leaving other

elements of mixture in gaseous phase. In this way, water vapor will get separated from others.

In a series rlc ac circuit, a second resistor is connected in parallel with the resistor previously in the circuit. as a result

raketka [301]

According to the given statement:

The frequency response does not change, which is the first thing we notice.

The new resistance at the resonance point causes a reduction in the circuit's current flow.
Z = R + R₂

<h3>The definition of series circuits:</h3>

electrical circuit. The path that the entire current takes as it passes through each component makes up a series circuit. Branching is used in parallel circuits to divide the current and limit the amount that flows through each branch.

<h3>How does a series circuit operate?</h3>

According to this definition, there are three principles of series circuits: all parts share the same current, resistances add up to a larger total resistance, and voltage drops add up to a larger total voltage. In the definition of a series circuit, all of these guidelines have their origin.

<h3>According to the given information:</h3>

The impedance of a series circuit is

Z₀² = R² + (X $_L$ -X $_C$ ) ²

The initial resistance impedance shifts to when we add another resistor to the series

Z² = (R + R₂) ² + (X $_L$ - X $_C$ ) ²

Let's examine this sentence.

The frequency response remains unchanged, which is the first thing we notice.
The new resistance at the resonance point causes the circuit's current to decrease.

Z = R + R₂
