Answer:
7.5Watts
Explanation:
Given parameters:
Force of lift = 25N
Height = 3.6m
Time = 12s
Unknown:
Power output = ?
Solution:
Power is the rate at which work is done ;
Power =
Power = = 7.5Watts
Answer:
Option C is correct
Explanation:
A supersaturated solution is one that has more solute dissolved than the solution should hold at that temperature.
Examples include carbonated water, sugar syrup, honey.
A solution of a chemical compound can be dissolved in heated water to prepare a supersaturated solution. A solution becomes supersaturated as its temperature is changed.
Answer:
Explanation:
The maximum charge on the capacitor will be, at the end of the process, given by the formula (and for our values):
The maximum current on the resistor will be, at the beginning of the process, given by the formula (and for our values):
Answer:
a = 6.7 m/s²
Explanation:
The formula to apply here is :
Mass * acceleration = Tension -weight
m*a = Ft -mg -----where m is mass of block, a is acceleration , Ft is force due to tension.
Given in the question that ;
Mass of block = 3 kg
Ft = 50 N
g= 10
m*a = Ft -mg
3*a = 50-30
3a= 20
a= 20/3
a= 6.7 m/s²
