I believe the answer is D hope it helps.
Answer:
Angular velocity of tire
Explanation:
Given:
Diameter of tire of an automobile =75.0 cm
Linear velocity of automobile = 90.0 km/hr
To find angular velocity of tire.
Diameter of tire in meters =
Radius of tire =
Linear velocity in meters per second =
Angular velocity is given by :
where represents linear velocity and represents radius of tire.
Plugging in values.
∴ (Answer)
The final volume of the gas is 3 L
Explanation:
We can solve this problem by applying Boyle's law, which states that:
"For a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
where
P is the pressure of the gas
V is its volume
The equation can also be rewritten as
For the sample of helium in this problem, we have:
Solving the equation, we can find , the final volume of the gas:

That there are not significate amounts of dark matter wihtin our solar system.
- The dark matter is a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity.
- The force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface is known as gravitational attraction.
- The luminous normal matter, such as protons, neutrons, electrons, and atoms in the universe, there are about 4 grams of nonluminous normal matter, mainly intergalactic hydrogen and helium.
