Answer: 313.24K
Explanation:
Given that:
Initial air pressure P1 = 210kPa
Initial Temperature T1 = 26°C
(Since, the SI unit of temperature is Kelvin, convert temperature in celsius to kelvin
26°C + 273 = 299K)
Final temperature T2 = ?
Final pressure P2 = 220kPa
Since, pressure and temperature are involved while volume is constant, apply the formula for pressure law
P1/T1 = P2/T2
210kPa/299K = 220kPa/T2
Cross multiply
210kPa x T2 = 220kPa x 299K
210 x T2 = 65780
T2 = (65780/210)
T2 = 313.24K
Thus, the temperature of the air in the tyre is 313.24K
Answer:
Both technicians are correct
Explanation:
Insulated rubber gloves or lineman’s gloves are a major requirement to ensure safety when working with high voltage parts of the hybrid electric vehicles because rubber is an insulator i.e. it does not allow direct contact of electricity with the body. These gloves are really important because these gloves can protect the technicians from electric shocks servicing the high voltage system on hybrid electric vehicles. It needs to be ensured that the gloves are of pure rubber and have no holes or cuts to ensure complete insulation. These gloves are also called class “0” gloves or gloves rated at 1000 V are used for this.
Similarly there are methods to shut off the high voltage to components and circuits in hybrid cars. These methods include but are not limited to:
• Turning the ignition off
• Disconnecting the 12-volt auxiliary battery
• Removing the main fuse, relay, or HV plug
So both the technicians are correct
B)False........... It's efficiency factor
Answer: true
Explanation: If the mass of an object is increased so is the gravitational pull
