Answer:
K = 500 x 10⁶ MPa
Explanation:
Given that
P = 10 MPa
V= 0.25 m ³
Reduction in the volume ,ΔV=- 0.005 cm³
We know that 1 m = 1000 cm
ΔV=- 0.005 cm³ = - 0.005 x 10⁻⁶ m³
We know that bulk modulus given as
Now by putting the values
We get
K = 500 x 10⁶ MPa
Therefore the bulk modulus of the elasticity will be 500 x 10⁶ MPa.
Answer:
Speed by walking is 33 miles per hour
And speed of by car is 88 miles per hour
Explanation:
We have given that it takes same time to walk 1212 miles as 3232 miles by car
Now let the speed by walk is x
As speed by car is 55 miles per hour faster than by walk = x+55
As time is same and we know that time is given as 
So 
x = 33 miles per hour
So speed by walking is 33 miles per hour
And so speed of car = 33+55 =88 miles per hour
<u>Answer :</u>
correct choice is option A
Motors convert electrical energy into mechanical energy. Generators convert mechanical energy into electrical energy.
Explanation :
Their difference is described as;
Premise MOTOR
- The Motor Converts Electrical imperatives into vitality .
- It uses control. (power)
- In partner degree motor this is to be given to the curl winding
- The Shaft of the motor is driven by the drawing in power made among loop and field.
- Engine seeks after Fleming's left guideline.
GENERATOR
- Generator changes over Mechanical essentialness to Electrical imperatives .
- It produces control (electricity)
- In the generator current is conveyed inside the curl winding.
- The Shaft is associated with the rotor and is driven by mechanical power.
- Generator seeks after Fleming's correct guideline. .
Sound waves in air are a series of <span>periodic disturbances, </span><span>periodic condensations and rarefactions,</span><span> and high- and low-pressure regions. It is all of the above. The answer is letter D.</span>
Because it generates high amounts of energy for a small amount of material, and doesn't produce as much pollution as fossil fuels.
