Following the definition of the center of mass, "In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero."
(see explanation below)
Answer:
0.7864m
Explanation:
Ignore air resistance (the ball's horizontal speed stays constant), the time it takes for the ball to travel 1.95 m horizontally at the rate of 4.87 m/s.
t = 1.95 / 4.88 = 0.4s
This is also the time it takes to fall vertically with gravitational acceleration of g = 9.81 m/s2. We can use the following equation of motion to estimate the vertical distance:
Answer:
± (.021 ) ohm
Explanation:
In the addition of two physical quantities , the uncertainties are simply added .
So , net uncertainty in the value of R will be
± (.007 +.014)
=± (.021 ) ohm
Answer:
The work done is 85200 J or N•m
Explanation:
Here,
Force = 200 N
Distance = 426 m
Now, For work done
<h3><u>Formula</u><u>:</u></h3>
<u>Work = Force × Distance.</u>
W = F × d
W = 200 × 426
W = 85200 J or N•m
Thus, The work done is 85200 J or N•m
