Try to have a calm morning before camp. A good night’s sleep and a good breakfast. Make sure to be cautious, follow all the rules for certain areas ( some maybe restricted ). Take lots of photos doing wacky stuff! Learn but have fun learning
If it's a distance graph, then it's a constant speed.
Answer:
The speed of nitrogen molecule is 1.87 m/s.
Explanation:
Given that,
Pressure = 2 atm
Density = 1.7 grams/liter
Atomic weight = 28 grams
We need to calculate the temperature
Using formula of idea gas




Put the value into the formula


We need to calculate the speed of nitrogen molecule
Using formula of RMS speed



Hence, The speed of nitrogen molecule is 1.87 m/s.
Answer: An object is in motion when its distance from another object is changing . A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving
Explanation:
The spring should have a greater displacement .
Greater spring constant = the more difficult it is to stretch a spring , due to stiffness.
