Answer: D
Explanation:
Forces can be divided into those that act by direct contact—such as when you push on a door to open it—and those that act at a distance, where there is no apparent physical contact between the objects. Magnetism, and electrical charge, and gravitation are examples of forces that act at a distance.
Spinal Cord!!! I did this earlier :D It is spinal cord because you know that if you break your spinal cord you can't move. :P Brainiliest would be awesome thanks :D
Answer:
The gas pressure inside the flask is higher than outside the flask ornthe atmospheric pressure.
Explanation:
Given a U-tube manometer with water in between each arm of U-tube. One end is open to the atmosphere while one end is sealed to a flask filled with a gas. The water in the open end of the tube is experiencing a pressure equal to the atmospheric pressure whereas the water at the end sealed of to the flask is experiencing pressure due to the gas in the flask.
If the water level in both arms of the tube are equal, then the pressure due to the gas is equal to atmospheric pressure.
If the water level in the arm sealed to the gas is higher than that of the open end, The gas pressure is less than the atmospheric pressure.
If the water level in the arm sealed to the flask is lower than the open end, the pressure due to the gas is higher than atmospheric pressure.
From the question, when the water level is higher outside the flask than inside, then the gas pressure inside the flask is higher than the atmospheric pressure.
Answer:
<h2>The answer is 870 miles</h2>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
<h3>distance = velocity × time </h3>
From the question
velocity = 290 miles/hour
time = 3 hours
The distance between the two cities is
distance = 290 × 3
We have the final answer as
<h3>870 miles</h3>
Hope this helps you
