What will be the temperature reading in Fahrenheit scale whe eading is 310 k?

Otrada [13]

The temperature reading in Fahrenheit scale when reading 310 K is 98.6F

<h3>What is temperature?</h3>

Temperature is the degree of hotness or coldness of the object.

Given is a temperature in Kelvin scale = 310 K

Temperature on centigrade scale = 310 -273 = 37°C

Temperature conversion from Centigrade to Fahrenheit is

C/5 = F -32/9

Plug the value, we get

37/5 = F-32/9

66.6 = F -32

F = 32+66.6 =

F = 98.6

Thus, the temperature of 310 K in Fahrenheit is 98.6F.

A 10 N force and a 30 N force act on an object in opposite directions. What is the net force on the object? Sketch a free body d

yarga [219]

Answer:

$Net_{F}$ = 30N - 10N = 20N

Please mark as brainliest!

It is appreciated hope this helps!

Explanation:

I have put what a simple free body force diagram that you would need for this question below!

Just swap out the 5N and 3N with 30N and 10N :)

10. Almost three-quarters of household energy use is due to the following:

Arturiano [62]

Answer: Energy consumption and sustainability is important so that it remain available for future generation.

Explanation:

1. The home furnaces are likely to require fuel like coal, which will directly emit carbon dioxide and carbon monoxide gases. These should be replaced with the electrical furnaces. The old or more power consuming air conditioners should be replaced with new ones.

2. The water heaters should be tankless so their capacity to heat more water could be possible. The water heaters should be electricity saving.

3. Washer and dryers should be water savy and electricity savy. A front-loading washing machine is useful energy saver.

4. The LED lights are more electricity saving than conventional bulbs. Halogen lights are also electricity saving.

a paratrooper jumps out of a plane and opens her parachute shortly afterward. 10 seconds later the upward force on the parachute

Flura [38]

Answer:

Acceleration = 2.45 m/s²

Explanation:

The resultant vertical force on the paratrooper = ma = upward force - total weight of both the parachute and the

Ma = W - Fu .............. Equation 1

Where Fu = upward force on the parachute, W = combined Weight of the parachute and the paratrooper

W = Mg......................... Equation 2

Making M the subject of formula

M = W/g...................... Equation 3

Where M = combined mass of the parachute and the paratrooper, g = acceleration due to gravity.

Given: W = 800 N, g = constant = 9.8 m/s²

Substituting these values into equation 3

W = 800/9.8

W = 81.63 kg.

<em>Also Given: Fu = 600 N, W = 800 N</em>

Substituting these values into equation 1

81.63a = 800 - 600

81.63a = 200

Dividing both side of the equation by the coefficient of a

81.63a/81.63 = 200/81.63

a = 2.45 m/s²

Therefore acceleration = 2.45 m/s²
