Answer:
the object will not return to the original position because it will not have any forces helping it to go up the hill
the center of mass falls since it is going downwards
Hope this helps!! have a great day
Explanation:
Answer:
KE = incident energy - work function
The maximum KE will be (3 - .6) eV = 2.4 eV
Answer:
Thank you so much! Have a great day!
Answer:
3. increases with an increase in temperature.
Explanation:
The air more water vapor at higher temperatures because at higher temperatures the air expands and the inter-molecular space increases so the room for water molecules increases.
Warm air keeps the water molecules warm and prevents them from condensing.
The air can hold the moisture only upto its saturation quantity after which the precipitation occurs in the form of rain, snow, hail, sleet etc.
Answer:
Time, t = 8 seconds
Explanation:
An object is thrown upward from the top of a 128-foot building with an initial velocity of 112 feet per second. The height h as a function of time t is given by :

We need to find the time when the object will hit the ground. When it will hit the ground, h = 0
So,

On solving the above quadratic equation, we get the value of t = 8 seconds. So, after 8 seconds the object will hit the ground. Hence, this is the required solution.
