Answer:
15 m
Explanation:
Given,
Mass ( m ) = 75 kg
Potential energy ( P.E ) = 11,025 J
To find : Hight ( h )
Formula : -
P.E = mgh
[ Note : The value of g = 9.8 m/s² ]
h = P.E / mg
= 11,025 / ( 75 x 9.8 )
= 11,025 / 735
h = 15 m
Hence,
15 m is the high off the ground must you be if you mass is 75 kg and you have 11,025 J of energy stored inside.
Answer:
18 kg/cm³
Explanation:Density=mass/ volume=450/25=18kg/cm³
In a direct current (DC) electrical circuit, the voltage (V in volts) is an expression of the available energy per unit charge which drives the electric current (I in amperes) around a closed circuit. Increasing the resistance (R in ohms) will proportionately decrease the current which may be driven through the circuit by the voltage.
Each quantity and each operational relationship in a battery-operated DC circuit has a direct analog in the water circuit. The nature of the analogies can help develop an understanding of the quantities in basic electric ciruits. In the water circuit, the pressure P drives the water around the closed loop of pipe at a certain volume flow rate F. If the resistance to flow R is increased, then the volume flow rate decreases proportionately. You may click any component or any relationship to explore the the details of the analogy with a DC electric circuit.

<u>RANCIDITY</u><u>:</u></h2>
=> Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour. An example of rancidity is when a chips pack is exposed to atmospheric air which results in a change in taste and odor.
