Explanation:
- A substance will float if it has a lower density than the liquid it is placed in.
- A substance will sink if its density exceeds that of the liquid.
Density of corn syrup = 
1) Density of gasoline = 
Gasoline's density is less than that of corn syrup, indicating it will float in corn syrup.
2) Density of water = 
Water's density is also less than that of corn syrup, meaning it will float in corn syrup.
3) Density of honey = 
Honey's density exceeds that of corn syrup, so it will sink in corn syrup.
4) Density of titanium = 
The density of titanium is greater than that of corn syrup, hence it will sink in corn syrup.
When the boat submerges completely in the pond, the water level of the pond rises.
A bathroom scale operates under gravitational influence. Typically, a reading is captured when your body applies force onto the scale. Yet in this scenario, as both you and the scale move downwards, your body ceases to press against the scale. Consequently, the result is:
<span>The scale reading will instantly drop to zero</span>
Response: a) 0.04 kW = 40 W
b) 0.05
Explanation:
A)
The thermal efficiency of the power cycle is calculated as Input / Output
Input = 10 kW + 14,400 kJ/min which translates to 10 kW + 14,400 kJ/(60s) = 10 kW + 14,400/60 kW.
Output equals 10 kW
Thus, Thermal Efficiency = Output / Input = 10 kW / 250 kW = 0.04 kW = 40 W
B)
Maximum Thermal Efficiency of the power cycle is defined as 1 - T1/T2
where T1 = 285 Kelvin
and T2 = 300 Kelvin
Thus, Maximum Thermal Efficiency = 1 - T1/T2 = 1 - 285/300 = 0.05
