A cart with an unknown mass is at rest on one side of a track. A student must find the mass of the cart by using newton’s second law. The student attaches a force probe to the cart and pulls it while keeping the force constant. A motion detector rests on the opposite end of the track to record the acceleration of the cart as it is pulled. The student uses the measured force and acceleration values and determines that the cart’s mass is 0. 4kg. When placed on a balance, the cart’s mass is found to be 0. 5kg. Which of the following could explain the difference in mass?.

It is estimated that 32 patrons will attend an event for every $100 spent in advertising. If tickets cost $75, how much can a promoter expect to increase sales if he spends $25,000 in advertising?.

Answers

In order to increase sales if he spends $25,000 in advertising, the promoter should be expecting 600,000 dollars

If It is estimated that 32 patrons will attend an event for every $100 spent in advertising.

The cost of tickets = $75,

If he spends $25,000 in advertising, divide the amount by 100 dollars

25000/100 = 250

This means 32 x 250 = 8000 patrons is estimated to attend an event.

Since each ticket cost 75 dollars, then, the promoter should expect to increase sales by multiplying 75 dollars by 8000 patrons. That is,

75 x 8000 = 600,000 dollars

Therefore, the promoter should be expecting 600,000 dollars to increase sales if he spends $25,000 in advertising.

Which of the following is an example of the self-fulfilling prophecy?.

Self-fulfilling prophecy is a psychological theory where what is believed or expected or said to a person comes to pass even if the belief is not a fact.

An example of  self-fulfilling prophecy is telling a person that they are so poor in mathematics. This might not be true but because the person is told repeatedly, the person begins to believe it and would eventually become poor in mathematics.

Self-fulfilling prophecy can be negative or positive. It depends on the way it is used.

Here are the options of this question:

telling blue-eyed people they are unattractive, then feeling bad and complimenting people with blue eyes to avoid feeling guilty telling people you hate boy bands, then taking your child to a boy band fan club meeting telling someone with dyslexia she cannot learn to read, leading her to become illiterate even though she could learn to read with a bit of extra effort telling your spouse you hate his cooking, then taking over the cooking yourself to avoid food poisoning

Would sound waves travel slower through air at the north pole or at the equator?.

Answers

yes they would travel slower at the north pole than the equator because the air is more dense and is harder to pass through

Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.

What are equators?

The Equator is the midline of the earth.  A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.

Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).

Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.
