<h2>Answer:</h2><h2>Temperature</h2>

<h3>About physical quantities:</h3>

Those quantities which can be measured directly or indirectly is called physical quantities.

There are two types of physical quantities.They are:

fundamental quantity

Those quantity which are not dependent upon any quantity are called fundamental quantity.for eg: length,mass time etc.

Derived Quantity

Those quantity which are dependent upon other quantities are called derived Quantity. for eg: volume,area etc.

<h2>About temperature:</h2>

Temperature is the degree of hotness and coldness of a body.Temperature is measured in degree,Celsius,degree Fahrenheit or Kelvin scale.Temperature is measured by using thermometer.

Hope this helps....

Good luck on your assignment.....

Answer:

<h2>Thermodynamic temperature</h2>

Explanation: Research states that ;

Thermodynamic temperature is the measure ( absolute) of temperature and is one of the principal parameters of thermodynamics.

It uses the kelvin scale for measurement and selects the triple point of water at 273.16 K as the fundamental fixing point.

Answer:

27,000 m

450 m/s

Explanation:

Assuming the initial velocity is 0 m/s:

v₀ = 0 m/s

a = 15 m/s²

t = 60 s

A) Find: Δy

Δy = v₀ t + ½ at²

Δy = (0 m/s) (60 s) + ½ (15 m/s²) (60 s)²

Δy = 27,000 m

B) Find: v_avg

v_avg = Δy / t

v_avg = 27,000 m / 60 s

v_avg = 450 m/s

Ierofanga [76]

Answer:

a) 5.197rev/s

b) Kf/Ki =2.28

Explanation:

a) Angular momentum of the system L = Iw

ButLi=Lf

Kiwi =Ifwf

wf = (Ii/If)will = (4.65/3.4)×3.8=5.197rev/s

b)Kinetic energy KE= 0.5Iw^2

Ki = 0.5Iiwi^2

Kf=0.5Ifwf^2

Kf/Ki = Ifwf/Iiwi

Kf/Ki = (4.65/3.4))(5.197/3.8)

Kf/Ki = 1.22(1.368)^2

Kf/Ki = 2.28

sineoko [7]

Answer:

2.03 x 10²⁴N

Explanation:

Given parameters:

Mass of moon = 7.34 x 10²²kg

Mass of the earth = 5.97 x 10²⁴kg

Distance = 3.8 x 10⁵km

Unknown:

Gravitational force of attraction = ?

Solution:

To find the gravitational force of attraction between the masses, we use the expression below;

F = $\frac{Gm_{1} m_{2} }{r^{2} }$

G is the universal gravitation constant

m is the mass

1 and 2 represents moon and earth

r is the distance

F = $\frac{6.67 x 10^{-11} x 7.34 x 10^{22} x 5.97 x 10^{24} }{(3.8 x 10^{5})^{2} }$

F = $\frac{2.92 x 10^{35} }{1.44 x 10^{11} }$ = 2.03 x 10²⁴N
