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

Complete Question
A proton is located at <3 x 10^{-10}, -5*10^{-10} , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton
Answer:
The vector position is 
Explanation:
From the question we are told that
The position of the proton is 
Generally the vector location of the proton is mathematically represented as
So substituting values
Answer:
15.1 N
Explanation:
mass of block (m) = 4 kg
angle of inclination = 36 degrees
applied force (P) = 31 N
acceleration due to gravity (g) = 9.8 m/s^{2}
since the block is moving at a constant speed, it means the acceleration is 0 and therefore the summation of all the forces acting on the body is 0
therefore
P - f - mgsinθ = 0
where
- P = applied force
- f = frictional force
- m = mass
- g = acceleration due to gravity
when P = 31 N and the block is pushed upward
31 - f - (4 x 9.8 x sin 36) = 0
f = 7.96 N
now that we have the value of the frictional force we can find P required to lower the block, our equation becomes p + f - mgsinθ = 0 since the block is to be lowered
P + f - mgsinθ = 0
P = mgsinθ - f
P = (4 x 9.8 x sin 36) - 7.96 = 15.1 N
Answer:
c.an equation that can be used to accurately calculate the pull of gravity between two objects
Explanation:
umm ok for you
The charge transported as a result of charging is 43200C .
we can note the following data from the statement :
Current (i) = 3A
Time interval (t) = 4 hrs = 14400secs
As we know ,
Current is defined as the rate of flow of the charges between two points when a potential difference is applied between them.
Mathematically , it can be written as
Current(i) = charge (q)/ time(t)
Q = i × t
= 3 × 14400
= 43200 C
By dividing the value of the current passed through the circuit by the time for which the charge is passed gives out the value of the charge passed .
