Why is it important to cite units when engaging in scientific conversation / problem solving?

It is really important to cite units while engaging with scientific problems as they help in evaluating the right solution without any mistake.

<u>Explanation: </u>

While solving analytical questions to evaluate the right answers, the units play a crucial role in the equations. With the help of units in the formula, we can easily judge whether we are placing the values in the same parameters and hence, lessen the probabilities of wrong answers.

For example, while adding two measurements i.e. 4 m and 36 cm; if we don't consider the units and move on with the addition, the answer will be 40. Now, the first thing is that we are adding two measurements of different parameters. Besides this, the answers will be wrong i.e. 4.36 m is the correct answer instead of 40 and that too without mentioning the unit.

The chances of selecting the wrong answer are more when we need to choose options out of multiple choices because here we often get confused. That's why we should always make sure that we approach the scientific questions along with the units.

What part of an electric circuit are the wires that carry the electric current

bezimeni [28]

Answer:

okay so, An electric circuit is a closed loop through which current can actually flow. All electric circuits must have a voltage source, for example a battery, and a conductor, which is usually a wire.

how does it flow or how does .current flow in a circuit ? When a wire is connected to battery terminals which is electrons, electrons flow from negative to positive. Electrons have a negative charge in case you didnt know. they are repelled from the negative and attracted to the positive.

if this helped please mark this as brainliest!!! :)

The position of a 55 g oscillating mass is given by x(t)=(2.0cm)cos(10t), where t is in seconds. determine the velocity at t=0.4

NNADVOKAT [17]

The position of the mass is given by (in cm):
$x(t)=2 \cos (10 t)$
The velocity is the derivative of the position:
$v(t) = \frac{dx(t)}{dt} =-10\cdot 2 \sin (10t)=-20 \sin (10t)$
Substituting t=0.40 s, we can find the velocity at this time:
$v(0.40 s)= -20 \sin (10 \cdot 0.4)=15 cm/s=15 \cdot 10^{-2}m/s$

8- A 20 KVA, 440/220 single-phase transformer has winding resistance as 0.090 and

Maurinko [17]

The total resistance referred to the HV side will be 0.36 ohm.

<h3>What is resistance?</h3>

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The total resistance referred to HV side is;

$\rm \frac{R_H}{R_L} =(\frac{V_P}{V_S})^2 \\\\ R_H=R_L(\frac{V_P}{V_S})^2\\\\ R_H=0.090 \times (\frac{440}{220})^2\\\\ R_H=4 \times 0.090 \\\\ R_H= 0.36 \ ohm$

Hence, the total resistance referred to the HV side will be 0.36 ohm.
