Answer:
The speed of the kid and the skateboard together is 0.723 m/s
Explanation:
Let the mass of the kid be
Let the mass of the skateboard be
The initial speed of the skateboard,
The initial horizontal speed of the boy as he jumps on the skateboard,
Let the speed of the kid and the skateboard together be v
According to the principle of conservation of momentum:
Substituting the appropriate values into the given equation
36 = 49.8 v
v = 36/49.8
v = 0.723 m/s

Answer:
- Gap between the plates
- No, practically not achievable
Solution:
As per the question:
Capacitance, C = 1 F
Area of the plate of the capacitor, A =
Now,
To calculate the distance, D between the plates of a parallel plate capacitor:
Thus
where
= permittivity of free space
Now,
This distance much smaller and is practically not possible
Explanation:
c. if the vector is oriented at 0° from the X -axis.
Answer:
Better Equilibrium Maintenance for better accuracy...
Explanation:
In the Galileo's experiment, there is no utilization of two equal masses at a time. However, as we can see in a Atwood Machine, there are two equal masses involved that make the whole system to be in a state of equilibrium and ultimately the better measurements of acceleration due to gravity.
