From the data given, the final velocity is equal to 6 m/s. This is from the equation a = vf - vo / t. The second kinetic equation to be used to determine the distance traveled is 2ax = vf2 - vo2. Substituting, 2*0.6*x = 6^2 - 3^2 ; x then is equal to 22.5 meters
<span>Answer: b. air pressure
</span>The weather station model purpose is giving information about the weather. The information including the temperature, the air pressure, the direction of the wind and other things. The air pressure will be detected using a barometer.
The weather station doesn't give altitude/latitude or air mass.
Explanation:
Displacement=Velocity×time
=24.7×16.00
=395.2m
Therefore the displacement within the time interval is 395.2m
Big Bang is a theory that, as stated above, has grown to become widely acceptable scientific explanation of the origin of things. Research would say that according to this theory, the Earth originated billion years ago through an explosive of a highly energized point.
Through this explosion, the elements were formed. However, only the lightest of the elements including hydrogen and helium, with traces of lithium and beryllium. From the choices, the answer would have to be the second choice, helium.
Answer: B. helium
Answer:
Explanation:
Given
mass of sled =26 kg
coefficient of static friction
coefficient of kinetic friction
In order to move sled from rest we need to provide a force greater than static friction which is given by
After Moving Sled kinetic friction comes in to play which is less than static friction
therefore minimum force to keep moving sledge at constant velocity is 18.34 N
