When we shake a mango tree, the mangoes fall down. It is because when we shake the tree, the mango tend to be rest due to inertia where as the branches are in motion. That is why the mangoes tend to be at rest due to inertia where as the branches are in the motion.
Answer:
Explanation:
Generally the workdone in moving the proton is mathematically represented as
Where 
So
Here 
is the velocity at A with value 50 m/s
So
Also
Here is the velocity at A with value 
=> 
=> 
So
Now this workdone is also mathematically represented as
So
Here 
So
Generally proton movement is in the direction of the electric field it means that 
So
I need help to I have a test and I need help to
Answer:
The automobile's acceleration in that time interval is -2 m/s^2
Explanation:
The acceleration is defined as the rate of change of the velocity.
The average acceleration in a given lapse of time is calculated as:
A = (final velocity - initial velocity)/time.
In this case, we have:
initial velocity = 31 m/s
final velocity = 15 m/s
time = 8 seconds.
Then the average acceleration is:
A = (15m/s - 31m/s)/8s = -2 m/s^2
Explanation:
I think it will increase a little bit ... just image ... if the temperature is 0, the velocity will be 0 too. because the vibration of atom is so weak and the sound cant progation.
