I’m sorry to say I don’t wanna be confusing but you dived it by 77 and get 99
D , since Voltage is one joule per coulomb
Projectile motion contains a horizontal (x) component, and a vertical (y) component. It is important to note that the x component, negating friction, is a constant velocity. Gravity only plays a part in the y component, where a = -9.8 m/s/s or a = -32 ft/s/s.
(a) The initial vertical velocity of the stone is 16.85 m/s and the initial horizontal velocity is 14.14 m/s.
(b) The final vertical velocity is 0 and the final horizontal velocity is 14.14 m/s.
<h3>
Initial vertical velocity</h3>
The initial vertical velocity of the stone is calculated as follows;
Vi = Vsinθ
Vi = 22 x sin(50)
Vi = 16.85 m/s
<h3>Initial horizontal velocity</h3>
Vxi = V cosθ
Vxi = 22 x cos(50)
Vxi = 14.14 m/s
<h3>Final vertical velocity of the stone</h3>
Vf = Vi - gt
where;
- Vf is the final vertical velocity = 0 at maximum height
<h3 /><h3>Final horizontal velocity of the stone</h3>
Vfx = Vxi = 14.14 m/s
Thus, the initial vertical velocity of the stone is 16.85 m/s and the initial horizontal velocity is 14.14 m/s.
The final vertical velocity is 0 and the final horizontal velocity is 14.14 m/s.

Answer:True
Explanation:
When we rub a glass rod with silk cloth electrons of glass rod are stripped away by the silk cloth making glass rod Positively charged i.e. relatively glass rod has more positive charge than negative charge.
During this Process no charge is created but transfer of the charges makes the rod relatively Positive and silk cloth relatively negative.
Thus net charge is same and no new charge is created.
