Answer:
0.22 atm
Explanation:
The total pressure is the sum of the partial pressures.
P = P₁ + P₂ + P₃
1.25 atm = 0.68 atm + 0.35 atm + P
P = 0.22 atm
Answer:
The answer to your question is Power = 0.98 W or 9.8 x 10⁻⁴ kW
Explanation:
Data
Power = ?
mass = 100 g = 0.1 kg
distance = 1 m
gravity = 9.8 m/s²
Formula
Power = Work / time
Process
1.- Calculate the Work
Work = Force x distance
Force = mass x gravity
Work = mass x gravity x distance
Work = (0.1 kg)(9,8)(1)
Work = 0.98 J
2.- Calculate the power
Power = 0.98 J / 1 h
Power = 0.98 W or 9.8 x 10⁻⁴ kW
Infrared radiation
Explanation:
The type of electromagnetic waves Jeff uses to make his goggles work are the infrared radiations.
Jeff is certainly using a night vision goggle to see in the dark . It senses infrared radiations
- Infrared radiations are part of the electromagnetic spectrum.
- Every hot objects gives off infrared radiations.
- These googles have thermal imaging sensors that detects these radiations.
- Naked eyes cannot see the radiations.
- The heat emitted is a form of radiation called the infrared radiation.
