The current in a hair dryer measures 15 amps the resistance of the hair dryer is 8 ohms

Physics
1 answer:
suter [353]3 years ago
3 0

The <u><em>voltage</em></u> at the input to the hair dryer is

V = (current) · (resistance)

V = (15 A) · (8 Ω)

<em>V = 120 volts</em>

<em>__________________________________</em>

The <em><u>power</u></em> dissipated by the hair dryer is

P = (current)²· (resistance)

P = (15 A)² · (8 Ω)

<em>P = 1800 watts </em>

SOVA2 [1]

Answer:

660 J/kg/°C

Explanation:

Heat lost by metal = heat gained by water

-m₁C₁ΔT₁ = m₂C₂ΔT₂

-(0.45 kg) C₁ (21°C − 80°C) = (0.70 kg) (4200 J/kg/°C) (21°C − 15°C)

C₁ = 660 J/kg/°C

Technician A says that the cooling system should be tested for leaks using a pressure-operated pressure pump. Technician B says
mart [117]

Answer:

The correct option is;

Technician A only

Explanation:

Leaks in the cooling system parts such as the radiator cap can be tested with a pressure operated hand pump by attaching the pump cap to the pump with an adaptor and apply pressure enough for there to be a release of pressure at the cap.

The pressure added to the system should be maintained for up to two minutes. If the pressure drops quicker, then there is likely to be leaks in the system

The freezing and boiling point of the coolant is measured with an antifreeze tester which carries the appropriate apparatus to measure the coolants freezing and boiling points.
