Ben walks 500 meters from his house to the corner store. He then walks back toward his house but stops to talk to aneighbor when he is 200 meters from the corner store. If it takes Ben 910 seconds from the time he leaves his house
until he stops to talk to his neighbor, what is his average velocity? (Round your answer to the nearest tenth of a meter
per second.)
Ben's average velocity is m/s.

Which is an example of the kinetic-molecular theory not holding true for a gas?The average kinetic energy of particles depends only on the temperature. The particles in a gas travel in straight lines in a continuous, random motion. The attraction between particles causes a gas to condense at low temperatures. The particles in a gas make up a small portion of the total volume of the gas.

Can you please explain me how to do integration in physics in a easy way?

Answers

The easiest way to explain it is roughly identical to the way that your teacher explained it in class. If there were any easier way ... like writing it here in a few paragraphs ... then that's what the teacher would have done. You would have been given the easy explanation on the first day of class, printed on one sheet of paper, and you would have had the rest of the year to practice it and get really good at it.
If the class spent a month teaching it, then that's about how long it takes. Sorry.

Which of these are considered an oxidizing mutagenic agent? x–rays benzopyrene gamma rays

Answers

X - rays are considered an oxidizing mutagenic agent. X-rays are high energy electrons that can cause damage when exposed under extreme conditions. The best technology that can block it is t using a lightweight type of metal foam. It can take in high energy collisions which also exhibits high forces. it does not only block x-rays but also, neutron radiation and gamma rays.

In the lungs there are tiny sacs of air, which are called alveoli. an oxygen molecule is trapped within a sac, and the uncertainty in its position is 0.12 mm. what is the minimum uncertainty in the speed of this oxygen molecule?

Answers

As we know that Heisenber's uncertainty law gives that

$\Delta x * \Delta P = (h)/(4\pi)$

here we know that

$\Delta x = uncertainty In Position = 0.12 mm$

$\DeltaP = uncertainty In Momentum = m*v$

now from the above formula we will have

$0.12 * 10^(-3)* 32*10^(-3)v = (h)/(4\pi)$

$3.84*10^(-6)*v = (6.6*10^(-34))/(4\pi)$

$v = 1.37 * 10^(-29)m/s$

so above is the uncertainty in the speed

What is the only force acting on an object orbiting Earth?A. air resistance
B. friction
C. inertia
D. gravity

Answers

The correct answer to the question is D). Gravity.

EXPLANATION:

Before coming into any conclusion, first we have to understand centripetal force.

Centripetal force is the force which is required to keep a body moving in a circular path. This force always acts along the radius and towards the centre.

As per the question, the object is moving around the earth. As it is moving in a orbit, it needs a centripetal force which will help the object stick to the orbit.

The centripetal force required is provided to the object by the gravitational force of earth .

Air resistance and friction play no role in imparting centripetal force to the object.

Hence, the correct option of this question is gravity, which is the only force that acts on an object orbiting earth.

im pretty sure its gravity
