Answers

Answer 1
China in 1100 AD, if I am wrong I'm sorry.
Answer 2

Answer:

Greece

Explanation:

It is believed that the reaction principle, the physical law of rocket motion, was first demonstrated about 360 B.C. by a Greek named Archytas. Far from demonstrating the reaction principle in a weapon, Archytas simply filled a hollow clay pigeon with water. He then suspended the clay pigeon by string over a fire. The heating of the water produced steam, and the clay pigeon could move under its own power as steam escaped through strategically placed holes. Archytas could hardly have imagined that the same basic principle would one day carry men to the Moon.

A: Keep your front wheels pointed straight ahead while you skid sideways off the road, and then

B: Take your foot off the gas pedal and steer your vehicle in the direction of the skid, even if it

C: Keep steering toward your lane on the road, even if you are skidding off the road sideways or

Answers

B - Take your foot off the gas pedal and steer your vehicle in the direction of the skid, even if it means you will drive off the road.

When driving on a highway in slippery road conditions, and the vehicle starts to skid towards the right shoulder, then one should remove one's foot from the gas pedal and steer the vehicle in the direction of the skid even if it means driving off the road.

Safety in driving means following certain rules and patterns of driving to ensure the safety of everyone on the road. Road safety involves numerous dos and don'ts that a driver must follow while driving even in cases of an accident.

While driving in normal conditions, rules such as safe driving, no drinking, etc. are important to be remembered. But in cases of weather change, be it snowy, rainy, or stormy, there are extra precautions that one can take to ensure safety on the road. In cases of skidding, it is important to remember that it is more important to follow the direction of the skid rather than trying to move away. This also includes stopping any attempts to brake because when we skid, there is not enough friction between the road's surface and the tire of the vehicle. The safest way to safely navigate a vehicle on a slippery road is to steer the wheel in the direction of the vehicle.

Therefore, the most important thing to remember is that when one skid while driving, it is best to go in the direction of the skid rather than try to avoid and drive away from it.

Complete the sentence with the correct response. In a two-way selection, if the initial statement is evaluated as , the code skips to the ELSE command.

Answers

Answer:

True.

The code skips the else command

Explanation:

I will answer this question with the following code segment

n = 1

If n > 0:

  Print("greater than 0")

else:

  Print("not greater than 0")

From the code segment above

Print("greater than 0") will be executed because the condition If n > 0 is true

Since the if condition is true, the else condition will not be executed

Answers

Answer: Use data from the previous steps because they show better results

Explanation:

A scientific bias occurs when there's a deviation between the observations of a researcher and the accurate representation of data and results.

In this case, the use of data from the previous steps because they show better results will bring about a data bias as it'll lead to inaccuracies of the data being represented.

Using cell references enter a formula in B6 to calculate monthly payments for the loan described in this worksheet Omit the optional arguement use a negative value for pv

Answers

Answer:

= PMT(B4/B2, B2 * B3, B1)

Explanation:

The syntax to use is:

= PMT(Rate,NPER, PV)

To answer this question, the following assumptions will be made.

B1 = Present Value i.e. PV

B2 = Number of Payment Period i.e n

B3 = Duration (in years)

B4 = Rate

So, the formula to enter in B6 is:

= PMT(B4/B2, B2 * B3, B1)

The above formula will return the monthly payment in cell B6
