Answer:

Explanation:

a ) When 1 kg water is boiled at constant pressure of 1  atm , its volume increases by following volume

(.824 - .001 )m³

.823 m³

work done by steam  = increase in volume x pressure

.823 x 10⁵ J

Heat added

=  latent heat of vaporization x mass

= 2260000 J x 1

= 22.6 x 10⁵ J

Increase in internal energy of gas

= heat added - work done by gas

= (22.6 - .823) x 10⁵ J

= 21.777 x 10⁵ J .

Echoic sensory memory is used when a lightning bolt flashes across the sky.
Ahat [919]
If the statement above answers whether the statement is true or false, then the answer is false. It is not true that the echoic sensory memory is used when a lightning bolt flashes across the sky because it does not have that kind of capacity. The echoic sensory memory is the one responsible for the auditory information.

A hydraulic press must be used to press-fit two components together in an assembly process. the system must generate at least 77
Kobotan [32]
The pressure generated by the piston at the input cylinder must be:

p = F / A = 250 lb-f / 30 in^2


The pressure generated by the piston at the output cylinders is p = F / A = 775 lb-f / A.


Pascal principle rules that both pressures are equal, so:


250 lb-f / 30 in^2 = 775 lb-f / A => A = 775 lb-f * 30 in^2 / 250 lb-f = 93 in^2


Gvien that each output cylinder are 30in^2 you need 93 / 30 = 3.1 cylinders.


Which means that at least you need 4 cylinders to generate a force at least of 775 lb-f.

A marble, a bowling ball, a basketball, and a baseball are all sitting on the top shelf of a display case. Which one has the gre
Katena32 [7]

Answer:

Bowling Ball

Explanation:

The potential energy depends on the factors: mass of the object and distance between the two objects. In this case the distance is between the ground and the balls. Here, the bowling ball is heaviest and its center of mass is farthest in comparison to other two balls. Thus, it has the greatest potential energy.
