Answer:

Ptotal= 0.794 atm

Explanation:

divide 4,500pa by 1atm or 101,325 passcal

4,500p

-----------      =   0.044atm

101,325p  

then you take 0.75 and add 0.044 which equals 0.794 atm

because 1 atm = 101,325 passcal

Can somebody help me. Will mark brainliest.
pickupchik [31]

Answer:

2.27%

Explanation:

The observed value of the boiling point = 71.8°C

The actual value of the boiling point = 70.2°C

We need to find the percentage error of the student's measurement. The percentage error in any value is given by :

\%=\dfrac{\text{calculated value-actual value}}{\text{actual value}}\times 100\\\\=\dfrac{71.8-70.2}{70.2}\times 100\\\\=2.27\%

So, the required percentage error is 2.27%.

A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical
Vaselesa [24]
<h2>A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical energy. nuclear energy.</h2><h2>ans: electromagnetic energy, thermal energy, solar energy, and mechanical energy.</h2>

Explanation:

Wind mill

It consist of shaft pole and blades that can rotate .

It converts wind energy into electrical energy .

The shaft of wind mill is connected to shaft of armature of generator .

When the fast moving wind rotates the blades of windmill its shaft rotates, armature rotates hence electricity is produced which is further used for various purposes .  

Advantage of using wing energy

it is natural renewable resource  

It is eco friendly  

Disadvantage :

1. It cant be established everywhere  

2. It requires large area  

3. It is an expensive project  

4. Wind dosen't blow all the time so win energy cant be produced every time  

5. Minimum speed of wind required is 15km per hour .

So, the wind turbine generating electricity involves mechanical energy of wing and blades .
