Explanation:

Bernoulli's principle -

This physical principle was given by Daniel Bernoulli .

According to this principle , as the speed of the moving fluid which can be a liquid or a gas increases , the pressure within the fluid reduces .

The principle of Bernoulli's have many practical applications ,

For example ,

<u>It is used in the carburetor and the atomizer , aspirator etc .</u>

Air in a thundercloud expands as it rises. If its initial temperature is 300 K and no energy is lost by thermal con- duction on

Ymorist [56]

Answer:

$T_{f}=227K$

Explanation:

Given data

Initial temperature of air Ti=300 K

Vf (final volume of air)=2Vi (initial volume of air )

To find

Final temperature

Solution

Since no energy is lost by thermal conduction during the process we categorize this process as an adiabatic one.Hence we apply;

$T_{i}V_{i}^{Y-1}=T_{f}V_{f}^{Y-1}\\T_{f}=T_{i}(\frac{V_{i}}{V_{f}} )^{Y-1}\\$

Where air is predominantly a diatomic gas Y=1.4m

Substitute the given values

$T_{f}=300K(\frac{V_{i}}{2V_{i}} )^{1.4-1}\\T_{f}=227K$

When a steady current flows through a resistor, the resistor heats up. We say that "electrical energy is dissipated" by the resi

drek231 [11]

Answer:

The dissipated energy in a resistor comes from the potential electric energy of a current source. This is known as the Joule effect. In fact, this energy is carried by the wires until the resistor.

A body moving with uniform acceleration has two points (5,15) and (20,60) on the (v t) graphs of its motion. calculate the accel

azamat

Answer:

3m/s²

Explanation:

The slope on a velocity time graph represents the acceleration, so if you simply use the slope formula, you can find the acceleration between those two points.

m=rise/run

m=(60-15)/(20-5)

m=45/15

m=3 m/s ² squared (therefore this is your constant acceleration from those two points).
