Answer:
The moon is being pulled to the earth by gravity, so the net force makes a circular pattern.
Explanation:
The force of gravity is a force that pulls objects toward the centre of the earth. The acceleration due to gravity of the moon is about 1.6 metre per second square which is comparatively smaller than the earth's 10metre per second. Therefore, the moon isn't completely pulled to the centre of the earth, but orbits around the earth

Answer and Explanation:
A. Exactly 25 J.
This is because the 25 J of energy that is holding down the book will always be the same, unless another force is being applied to hit to either make it heaver for a combined force of J energy, or something is lifting it, which will subtract the force of J of energy whilst moving.

What is the average speed of a car that travelled 400 miles in 6 hours?
Answers
Answer:
About 66 miles per hour
Explanation:
Based on the information given we can assume the car traveled the same number of miles every hour meaning all we need to do is divide.
400/6 ≈ 66 miles per hour
Answer
66 mph

how to do this please
Answers
Answer:
1) see the diagram below
2) (b) the length of the wire being tested
Explanation:
1) An ammeter is connected in series with the circuit branch in which you want to measure current. "Conventional current" enters the positive terminal of the ammeter. (You can think of it as a voltmeter across a small resistor. The polarity of the voltage matches the polarity of the current.)
A voltmeter is connected in parallel with the circuit element of interest. Here, you want to measure the voltage across the wire, so the voltmeter is placed in parallel with the wire. The positive terminal of the voltmeter is connected to the end of the circuit element that has the higher (more positive) potential.
__
2) The wording of the problem tells you which variable is independent:
"A varies with B" means the independent variable is B
Here, the independent variable is the length of the wire.

A girl runs 40m due south in 40 seconds an d then 20m due north in 10 secondsCalculate.
the average speed,
her average velocity .
in her change in velocity for the whole journey!
Answers
The average speed of the girl is 1.2 m/s.
Average velocity is defined as the trade in position or displacement (∆x) divided by the time durations (∆t) wherein the displacement takes place. The common velocity can be effective or negative depending upon the sign of the displacement. The SI unit of average velocity is meters per second (m/s or ms-1).
Given;
Total distance = 40 + 20 = 60 M
Displacement = 40 - 20 = 20 m south
total time = 40 + 10 = 50 seconds
Average speed = total distance / total time
= 60/50
= 1.2 m/s
average velocity = total displacement / total time
= 20 / 50
= 0.4 m/s due south.
Average velocity is calculated by means of dividing your displacement (a vector pointing out of your initial role in your final position) through the entire time; the average pace is calculated by way of dividing the overall distance you traveled by means of the total time.

2. Why is alcohol thermometer not suitable to measure high temperature?
Answers
Answer:
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.
Explanation:
It is less durable because alcohol evaporates faster than mercury. It cannot measure high temperature because of a low boiling point. It wets the walls of the thermometer, which can adversely impact the accuracy of readings

Suppose that we replace the aluminum with a mystery metal and repeat the experiment in the video. As in the video, the mass of the metal is the same as that of the water. Room temperature is about 20∘C before the start of the experiment. The water heats up to 40∘C, and the mystery metal heats up to 80∘C. Compared to that of water, the heat capacity of our mystery metal is
Answers
Answer: b) one-third as great.
Explanation:
The options include:
a) three times greater.
b) one-third as great.
c) half as great.
d) two times greater.
e) the same.
Since the water heats up to 40°C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (40°C-20°C).= 20°C
Since mystery metal heats up to 80∘C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (80°C-20°C).= 60°C.
Therefore, based on the calculation, when compared to that of water, the heat capacity of our mystery metal is (20/60) = 1/3 one-third as great.

this is almost similar to how a syringe works. when the pump is drown out, air in the barrel expands and pressure is reduced to below atmospheric pressure. the air from outside the pump is at high pressure so it flows past the leather washer into the barrel. at some point, the higher pressure in the tyre closes for valve.
when the pump handle is pushed in the air is forced into the tyre though the tyre valve which now opens
