Juan measured the temperature of salt water. He then added 273 to the measured value. Which conversion is Juan most likely doing
Semmy [17]
If Juan used a Celsius thermometer, it would tell him the Celsius temperature.

If he added 273 to that number, he'd have the "absolute" or Kelvin temperature.

Which of the following is a way earth’s water (hydrosphere) is directly affected by pollution?
ASHA 777 [7]

The toxic runoff from the farms will directly enters the water bodies of the earth through the drainage system.

The emissions from the cars will go into atmosphere and will react with water and then it will enter the earth's water. So, it is not directly affecting the earth's water.

The dumping trash on roadsides do not enter the earth's water. It can enter the earth's water through rains.

The production of oxygen by trees is not pollution.

Hence, option (A) is correct.

You and your friend throw balloons filled with water from the roof of a several story apartment house. You simply drop a balloon
ivann1987 [24]

Answer:

74.529 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.8 m/s²

For first ball

s=ut+\frac{1}{2}at^2\\\Rightarrow s=0\times t+\frac{1}{2}\times 9.8\times t^2\\\Rightarrow s=4.9t^2\ m

For second ball

s=ut+\frac{1}{2}at^2\\\Rightarrow s=50.96\times (t-2.6)+\frac{1}{2}\times 9.8\times (t-2.6)^2\\\Rightarrow s=25.48t-99.372+4.9t^2

As the displacement is equal

25.48t-99.372+4.9t^2=4.9t^2\\\Rightarrow t=\frac{99.372}{25.48}\\\Rightarrow t=3.9\ s

s=4.9\times 3.9^2=74.529\ m

So, height of the building is 74.529 m
