Answer:

<u>Conventions used in SI to indicate units are as follows:</u>

Only singular form of units are used. for example: use kg and not kgs.
Do not use full stop after the abbreviations of any unit. for example: do not use kg. or cm.
Use one space between last numeric digit and SI unit. for example: 10 cm, 9 km.
Symbols and words should not be mixed. for example: use Kilogram per cubic and not kilogram/m3.
While writing numerals, only the symbols of the units should be written. for example: use 10 cm and not Ten cm.
Units named after a scientist should be written in small letters. for example: newton, henry.
Degree sign should not be used when the kelvin unit is used. for exmaple: use 37° and not 37°k

Moment of inertia Wheel If you lift the front wheel of a poorly maintained bicycle off the ground and then start it spinning at

Vinil7 [7]

Answer:

0.113097335529 Nm

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

a = Acceleration

I = Moment of inertia = 0.3 kgm²

$\omega_f=\omega_i+\alpha t\\\Rightarrow \alpha=\dfrac{\omega_f-\omega_i}{t}\\\Rightarrow \alpha=\dfrac{0-0.72\times 2\pi}{12}\\\Rightarrow \alpha=-0.376991118431\ rad/s^2$

Torque is given by

$\tau=I\alpha\\\Rightarrow \tau=0.3\times (-0.376991118431)\\\Rightarrow \tau=-0.113097335529\ Nm$

The magnitude of torque is 0.113097335529 Nm

Which of the following statements is true about the variation of pressure in function of the depth? O Pressure decreases exponen

mrs_skeptik [129]

Answer:

The answer is: Pressure increases linearly with the depth

Explanation:

In this case, the definition of pressure is:

$P = \frac{F}{A}$

where F = mg is the weight of the fluid over the body, and A is the area of the surface to which the force is exerted. If we consider $\rho = m/V$ , then

$P = \frac{mg}{A} = \frac{\rho Vg}{A}$ .

Volume can be expressed as V = A*h, where A is the cross section of the column of the fluid over the body and h is the height of the column, in other words, the depth.

$P = \frac{A\rho gh}{A}= \rho g h$ ,

which means that pressure increases linearly with the depth in a factor of $\rho g$ .
