Don't know what an unbalanced force is, but this would be my solution.
Answer:
v = 10.47 m/s
a = 219.32 m/s²
Explanation:
The velocity of the stone can be given by the following formula:
v = r ω
where,
v = linear velocity of the stone = ?
r = radius of tire = 0.5 m
ω = angular velocity = (200 rev/min)(2π rad/1 rev)(1 min/60 s) = 20.94 rad/s
Therefore,
v = (0.5 m)(20.94 rad/s)
<u>v = 10.47 m/s</u>
<u></u>
The acceleration of the stone will be equal to the centripetal acceleration. Therefore,
a = v²/r
a = (10.47 m/s)²/0.5 m
<u>a = 219.32 m/s²</u>
Answer:
The change in velocity is 15.83 [m/s]
Explanation:
Using the Newton's second law we have:
ΣF = m*a
The force in the graph is 185 N, therefore:
Now using the following kinematic equation:
Now replacing the values:
Answer and Explanation:
The elements which have 1 2 or 3 valance electron in their valence cell those elements loses their electron to maintain their octet and for becoming stable and, if they loses electron positive charge will create and these ions are called cation
Example : In ionic compound Na has 1 valance electron which it is losses and form
