Answer:
c
10 A
Explanation:
Use the equation that calculates voltage: V = IR (That's capital "i")
"V" represents voltage. It's measured in the unit volts, the symbol V.
"I" represents current. It's measured in amperes, the symbol A.
"R" represents resistance. It's measured in ohms, the symbol Ω.
From the question, we know the source is 120 V and the resistance is 12Ω.
Substitute V = 120V, R = 12Ω into the equations. Isolate "I" to find the current.
V = (I)(R)
120V = (I)(12Ω)
I = 120V ÷ 12Ω
I = 10A
Therefore:
The current of a 12-ohm hair dryer that is connected to a 120-volt power source is <u>10 A (10-amps)</u>.

Answer:
3.122×10¹⁴ g/cm³
Explanation:
Diameter of neutron star = 23 km = 2300000 cm
Radius of neutron star = 2300000/2 = 1150000 cm = r
Mass of neutron star = 1.989 × 10³⁰ kg = 1.989 × 10³³ g = m
Volume of neutron star
Density = Mass / Volume
∴ Density of neutron star is 3.122×10¹⁴ g/cm³

The correct option is;
The proposal is denied, because participants will likely suffer psychological harm
Explanation:
Among the recommendations in the report on ethical research with children, it is suggested that the following should be observed by researchers;
1) Seeking consent should be a continuous process
2) Contemplate payment forms other than money to allow more discretion on child safety
3) Have two way communication with the child
4) Ask for assent of the child participating in the research
The above APA suggestions where not met by the researcher in the study.
