If the body temperature of a person is recorded as 37°C, what is the person’s body temperature in K? Round your answer to the nearest whole number.
A. 236
B. 3
C. 99
D. 310
Answer:
D
Explanation:
0 degrees Celsius is equal to 273.15 degrees Kelvin. The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15. in short : T(K) = T(°C) + 273.15
Answer: D
Explanation: 37 celsius is equal to 310.15 kelvin and if you round it to the nearest whole number you get 310.
Water contamination is often measured in parts per million (ppm) . If the concentration of the pollutant is 5 ppm, that means there are 5 parts of the contaminant in 1 million parts of water.

Your science teacher has provided the following materials to investigate the factors that affect the strength of electric and magnetic forces.
• large iron nail – 5 mm diameter
• 100 cm of thinly wrapped copper wire
• D battery
• electrical tape
• wire strip
• thumb tacks -assorted sizes
• paperclips – assorted sizes
Design an investigation you could carry out to determine the factors that affect the strength of electrical and magnetic forces.
The strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.
Whta is a magnetic field?A magnetic field can be defined as magnetic work exerted on electric charges that are in motion (movement).
Conversely, an electric field is an area where an electric current is applied and electron force can be estimated per Volts per Meter.
In conclusion, the strength of the electric field can be estimated as force per electric charge, whereas the strength of a magnetic field depends on the force of electrons and velocity.

which statement describes how adding oil effects the mechanical efficiency of a car's engine?
Answer:
Mechanical efficiency accounts for losses due to engine friction and ancillaries such as the lubricant pump, coolant pump, fuel pump and cooling fan. Engine friction arises whenever there is relative motion between parts. Journal bearings on the crankshaft, connecting rods and camshaft as well as piston rings and piston skirts are important sources
Explanation:
Which of these would have the highest temperature?
A. ice
B. water
C. water vapor
Answer:
Water vapor
Explanation:
because water vapor is gas and gas particles move faster than solid particles (which stick together) and water particles ( with a somewhat normal movement) and the faster the particle, the hotter the substance is. With that being said C is the correct answer.
