A particle is moving in a circle of diameter 5. calculate the distance covered and the displacement when it completes 3 revoluti

Mamont248 [21]

Total distance covered is 47.1 m whereas displacement is zero.

<h3>Calculation:</h3>

Given,

Diameter, d = 5 m

No. of revolutions = 3

Radius, r = 5/2 = 2.5 m

To find,

Distance =?

Displacement =?

Distance covered in one revolution = 2πr

Put the values in this,

Distance = 2 × 3.14 × 2.5

= 15.7 m

Total distance covered in 3 revolution = 3 × 31.4

= 47.1 m

Displacement is the change in the position of the object or the distance between the initial and final position.

After 3 revolutions the particle comes back to its initial position. Therefore, the displacement is zero.

Hence, the total distance covered in 3 resolutions is 47.1 m whereas displacement is zero.

Step 1, when solving a two dimensional, multi-charge problem, is to define the vectors. Please identify the next five steps, in

Maksim231197 [3]

Answer: The next 5 steps are.

step 2: Find the magnitude of vectors.

step 3: Calculate 'x' and 'y' components.

step 4: Sum the above obtained vector components.

step 5: Calculate the magnitude of Resultant Vector.

Step 6: Determine the direction of the resultant vector.

Explanation:

Let the two vectors be 'A' and 'B'.

Let A = $x_{1} \hat{i}+y_{1}\hat{j}+z_{1}\hat{k}$ and B = $x_{2} \hat{i}+y_{2}\hat{j}+z_{2}\hat{k}$

It is given that, when solving a two dimensional, multi-charge problem, is to define the vectors.

So, step 1 is to define the vectors A and B.

In step 2, we find the magnitude of the vectors by,

$|A|=\sqrt{x_1^2+y_1^2+z_1^2}$

$|B|=\sqrt{x_2^2+y_2^2+z_2^2}$

In step 3, we find the components 'x' and 'y'

Then in step 4, we sum the components. Now we get the Resultant vector (R).

In step 5, Calculate the magnitude of 'R' using the above formula to find magnitude.

In step 6, we determine the direction of 'R'.

Does the epiglottis close the trachea when u swallow food

stiks02 [169]

Answer:

A flap of tissue called (the epiglottis) sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow. But in some cases, food or drink can enter the trachea. It may go down as you swallow.

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil

kondaur [170]

Answer:

a) $\eta_{th} = 46.1\,\%$ , b) $\eta_{th,real} = 36.667\,\%$

Explanation:

a) The maximum possible thermal efficiency of the power plant is given by the Carnot's Cycle thermal efficiency, which consider a reversible power cycle according to the Second Law of Thermodynamics, whose formula is:

$\eta_{th} = \left(1-\frac{T_{L}}{T_{H}} \right)\times 100\,\%$
