Calculate the potential energy associated with 1 m^3 of water at 607 feet tall taking the mass of 1 m^3 of water to be 1000 kg
Lady bird [3.3K]

Answer:

1813.137 KJ

Step-by-step explanation:

potential energy of the body = mgH

where m is mass in Kg , g= 9.81 m/sec^2 and H= height in m

here m= 1000 kg, g= 9.81 m/s^2  and H= 607 feet = 607×0.305= 185.135 m

hence the potential energy p= 1000×9.81×185.135= 1813137.2 J

= 1813.137 KJ

hence the potential energy associated with 1 m^3 of water at 607 feet tall taking the mass as 1000 kg is = 1813.137 KJ

What effect does 'h' have on the graph of a parabola?
Kipish [7]

The effect that  'h' have on the graph of a parabola is Horizontal shift or translation .

<h3>What is translation?</h3>

A translation is the movement of  a shape up, down , this can also be movement from side to side.

Even though there is movement,   its appearance remains the same in any other way, hence, h values cause left or right movement with respect to the graph.

Use the drop-down menus to complete the statements about factoring 14x2 + 6x – 7x – 3 by grouping.
Stella [2.4K]

Answer:1.  GCF of the group ( 6 x - 3 ) is 3.

2.  The common binomial factor is 2 x - 1.

3.  The factored expression is:  ( 2 x - 1 ) ( 7 x + 3 ).

Step-by-step explanation:

14 x² + 6 x - 7 x - 3 =

= ( 14 x² - 7 x ) + ( 6 x - 3 ) =

= 7 x ( 2 x - 1 ) + 3 ( 2 x - 1 ) =

= ( 2 x - 1 ) ( 7 x + 3 )
