The correct choice is

D.What is the best angle to throw a ball for maximum distance

A) Incorrect . Since the which sport is fun varies person to person.

B) Incorrect. This question does not need a scientific investigation to be carried out to answer it. instead we can search the for the records of the pitcher of the last hundred years and then do a comparison.

C) Incorrect. This is more of general knowledge question

D) Correct. we can carry out a scientific investigation by throwing a ball at same speed and various angles and check at which angle does the ball travel the maximum distance.

A vacuum gage connected to a chamber reads 39 kPa at a location where the atmospheric pressure is 92 kPa. Determine the absolute

Nata [24]

Answer: 53 kPa

Explanation:

Absolute pressure is a pressure value referred to absolute zero or vacuum. This value indicates the total pressure to which a body or system (the chamber in this situation) is subjected, considering the total pressure acting on it.

In this sense, the equation that will be useful in this case is:

$P_{atmospheric}= P_{absolute} + P_{vacuum}$ (1)

Where:

$P_{atmospheric}=92 kPa$ is the atmospheric pressure

$P_{vacuum}=39 kPa$ is the vacuum pressure

$P_{absolute}$ is the absolute pressure

Isolating $P_{absolute}$ from (1):

$P_{absolute}=P_{atmospheric} - P_{vacuum}$ (2)

$P_{absolute}=92 kPa - 39 kPa$ (3)

Finally:

$P_{absolute}=53 kPa=53(10)^{3} Pa$ This is the absolute pressure in the chamber

<h3 /><h3>What is an electromagnetic wave?</h3>

The waves that are related to both electricity and magnetism are known as electromagnetic (EM) waves. These waves are made up of time-varying electric and magnetic fields that travel over space.

These waves, which are related to electricity and magnetism, would undoubtedly spread in space. The waves that are related to both electricity and magnetism are known as electromagnetic (EM) waves.

These waves are made up of time-varying electric and magnetic fields that travel over space. These waves, which are related to electricity and magnetism, would undoubtedly spread in space.

Hence option 1 is right because the 'Electromagnetic Waves' these line is about a different topic than the rest of Shondra’s notes.
