Answer:
A symbol for a battery.
Explanation:
A battery, because every sinlge circuit AC or DC must have a source of energy, to supply it to every single device that is part of the circuit.
The voltage is defined by the Ohm's law and it is equal to the product of the current by the resistance.
Vo = 5.89 m/s Y = 1.27 m g = 9.81 m/s^2
Time to height
Tr = Vo / g Tr = (5.89 m/s) / (9.81 m/s^2) Tr = 0.60 s
Max height achieved is:
H = Vo^2 / [2g] H = (5.89 )^2 / [ 2 * (9.81) ] H = (34.69) / [19.62] H = 1.77 m
It falls that distance, minus Andrew's catch distance:
h = H - Y h = (1.77 m) - (1.27 m) h = 0.5 m
Time to descend is therefore:
Tf = √ { [2h] / g ] Tf = √ { [ 2 * (0.5 m) ] / (9.81 m/s^2) } Tf = √ { [ 1.0 m ] / (9.81 m/s^2) } Tf = √ { 0.102 s^2 } Tf = 0.32 s
Total time is rise plus fall therefore:
Tt = Tr + Tf Tt = (0.60 s) + (0.32 s) Tt = 0.92 s (ANSWER)
You will need rocks brick and water.
The positive benefit of the uranium mining will be felt by the people and economy because uranium mining give us enough resource to provide sustainable and low cost method of generating energy.
The environment on the other hand , will only be exposed to the negative impact. If the miners fail to store the waste properly, the uranium could make the environment around it become really toxic and unhabitable.
Number of Washers . . . Total Mass . . . Total Force . . . Ratio
1 ................................................0.6 kg ................5.9 N ........... 9.83 N/kg
2 ................................................1.2 kg ...............11.8 N ............ 9.83 N/kg
3 ................................................1.8 kg ..............17.6 N ............. 9.78 N/kg
4 ...............................................2.5 kg .............24.5 N ............. 9.80 N/kg
5 ...............................................3.2 kg ..............31.4 N ............. 9.81 N/kg
The ratios are listed in the table.
The ratio seems to be constant, and not depend on the number of washers or the total mass. It's always about 9.8 Newtons per kilogram of mass. There must be something special about that number.
