64 g of sulfur dioxide (SO2) contains 32 g of oxygen. Calculate how much sulfur it contains.
Ghella [55]
In sulfur dioxide, there are 2 oxygen atoms and 1 sulfur atom. As there are 32g of sulfur and 32g of oxygen, that would mean that each oxygen atom would weigh about 16g. Given that, the mass of a single sulfur atom is twice that of a single oxygen atom.

At takeoff, the horizontal and vertical velocity of long jumper are 57.8 m/s and 5.6 m/s respectively. What is the resultant vel
Lady bird [3.3K]

Apply the Pythagorean theorem to get the resultant velocity:

V = \sqrt{Vx^{2}+Vy^{2}}

Given values:

Vx = 57.8m/s

Vy = 5.6m/s

Plug in and solve for V:

V = 58.1m/s

EDIT: Let's get the direction of the resultant velocity as well.

This equation will give the angle of the velocity as measured off of the ground:

θ = tan⁻¹(Vy/Vx)

Again, the given values are:

Vx = 57.8m/s

Vy = 5.6m/s

Plug in the values and solve for the angle θ:

θ = tan⁻¹(5.6/57.8)

θ = 5.5°

The resultant velocity is oriented 5.5° off the ground.

How do the sizes of the inner planets (from the sun to the asteroid belt) compare to the sizes of the outer planets?
Oxana [17]

Answer:

The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune. The outer planets are called gas giants and have a diameter of greater than 48,000 kilometers.

A pendulum takes 4 seconds to make one complete swing. A man walks 100m in a straight line while the pendulum makes 20 complete
irina [24]

The average velocity of the man is determined as 1.25 m/s.

<h3>Average velocity of the man</h3>

Total distance traveled by the man = 100 m

If 1 complete cycle = 4 s

  20 complete cycle = ?

= 20 x 4 s

= 80 s

Average velocity = total distance/total time

Average velocity = 100 m/80 s

Average velocity = 1.25 m/s

Thus, the average velocity of the man is determined as 1.25 m/s.
