Explanation:
Answer:
The required bulk modulus is Psi. So, the answer is non of these.
Explanation:
Change in pressure of the fluid is directly proportional to the volumetric strain. The constant of proportionality is the bulk modulus of the fluid.
Step1
Given:
Percentage change in volume is 1%.
Change in pressure is 10000 Psi.
Calculation:
Step2
Volumetric strain is calculated as follows:
Step3
Bulk modulus is calculated as follows:
\frac{\bigtriangleup V}{V}=0.01
K = 1000000 Psi.
Thus, the required bulk modulus is Psi.
Answer:
Resistance, R = 2.04 Ohms.
Explanation:
Given the following data;
Current = 7 amps
Circuit voltage = 120 Volts
Power = 100 Watts
To find the resistance;
First of all, we would calculate the potential difference (voltage level) used by the radio.
Power = current * voltage
100 = 7 * voltage
Voltage = 100/7
Voltage = 14.29 Volts
Next, we solve for the resistance of the radio;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Substituting into the formula, we have;
Resistance, R = 2.04 Ohms.
