Answer:

He should study the chapter about laws to get a better understanding about the laws that govern physical objects.

Explanation:

Small light atoms can diffuse through tiny pores in stretched rubber much more easily than larger heavier molecule. However, helium balloons don't completely deflate when helium atoms diffuse out of the balloon, because some air molecules also move into the balloon.

soldi70 [24.7K]

Answer:

98.13m

Explanation:

Complete question

Daniel is 50.0 meters away from a building. Tip of the building makes an angle of 63.0° with the horizontal. What is the height of the building

CHECK THE ATTACHMENT

From the figure, using trigonometry

Tan(θ ) = opposite/adjacent

Where Angle (θ )= 63°

Opposite= X = height of the building

Adjacent= 50 m

Then substitute the values we have

Tan(63)= X/50

1.9626= X/50

X= 1.9626 × 50

X= 98.13m

Hence, the height of the building is 98.13m
