eir observations in the chart shown. If the people are all lined up on the street at different blocks, and the police siren starts at block 3, which statement describes what block each person is standing at? Wycleff is on block 1, Lilly is on block 4, Quincy is on block 12, and Emilia is on block 17. Lilly is on block 1, Wycleff is on block 4, Quincy is on block 12, and Emilia is on block 17. Lilly is on block 1, Wycleff is on block 4, Emilia is on block 12, and Quincy is on block 17. Wycleff is on block 1, Lilly is on block 4, Emilia is on block 12, and Quincy is on block 17.

Answer:

Wycleff is on block 1, Lilly is on block 4, Emilia is on block 12, and Quincy is on block 17.

Explanation:

Wycleff was at block 1 and heard a low pitch sound the whole time, so the police car must have been moving away from him.

Lilly observed was in block 4 change in pitch first.  So the car must have passed her first.

Emilia was at block 12 observed a Doppler effect after Lilly.  So the car passed her after passing Lilly

Quincy was at block 17 so she heard a high pitch sound the whole time, so the police car must have been moving toward him.

The acceleration due to gravity on Earth is 9.80 m/s2. If the mass of a honeybee is 0.000100 kilograms, what is the weight of th
Yuliya22 [10]

Answer:

0.00098 N

Explanation:

The weight of an object is given by:

W=mg

where

m is the mass of the object

g is the gravitational acceleration on the planet

In this problem, we have:

m=0.0001 kg is the mass of the honeybee

g=9.8 m/s^2 is the acceleration due to gravity

Substituting into the equation, we find:

W=mg=(0.0001 kg)(9.8 m/s^2)=0.00098 N

Which of the following activities would be fueled by adenosine triphosphate (ATP) and the phosphagen system?A. 400-meter sprintB
Ksenya-84 [330]

Answer:

C

Explanation:

The Phosphagen System or Adenosine TriPhosphate - Creatine Phosphate (ATP-CP) is available in the muscles in a limited quantity, hence the amount of energy that is released through Phosphagen system is limited.

As a result the phosphagen stored in the muscle is exhausted vigorously and can only be used for activities which require very high energy for a very short duration of time.

Why do you think most models show the scale sizes of the planets but do not show the scale distances between the planets?
Effectus [21]

Explanation:

If both distance and size are proportional to that in the solar system, the model would be essentially useless.

For example, if the sun were represented by a marble 1 cm in diameter, the planet Neptune would be represented by a grain of sand .3 mm in diameter about 32.3 meters (106 ft) away. The largest planet, Jupiter, would be a larger sand grain, 1 mm in diameter, about 5.6 meters from the sun. Earth would be less than 0.1 mm in diameter, about 1 meter away from the sun.

Such a model would barely fit into a gymnasium (basketball court), and the elements of it would be very difficult to find without a map.
