Answer: Tech A is correct
Explanation:
Every vehicle has ignition system and without this system,it will not work. The battery of everything vehicle contain energy that start the vehicle and ignore it to start working. Electrical current move from the vehicle's battery and get to the induction coil, the induction coil increases the voltage in it so that the plug will be ignited. The spark plugs produce fire. The spark plug is connected to the ignition system. Once voltage is produced from the induction coil, electrical impulses move from induction coil to insulated plug wires. The spark plug need a very high voltage from the small voltage battery. Once the high voltage exceed the dielectric strength of the gases, spark jump the gap between the plug's fire end.
The angle above the horizontal of the motion of mass A + B after the collision. as well as others are mathematically given as
- vf/vA= 0.94
- 2vf^2 / 5vA^2 = 0.35
<h3>What is
Collison equilibrium?</h3>
According to the collision hypothesis of chemistry, chemical reactions happen when two molecules or atoms collide.
Generally, the equation for Collison equilibrium is mathematically given as
For horizontal motion
mvAx+m2vAx = 2mvfx
For vertical motion
-mvAy+m2vAy = 2mvfy
vfy = 1/2 vAy
(b)
vf/vA= 0.94
(c)
![Ef/Ei = \frac{(1/2 * (2m) * (vf)^2) }{ (1/2 * m * (vA)^2) + 1/2*m*(2vA)^2) ]}](https://tex.z-dn.net/?f=Ef%2FEi%20%3D%20%5Cfrac%7B%281%2F2%20%2A%20%282m%29%20%2A%20%28vf%29%5E2%29%20%7D%7B%20%281%2F2%20%2A%20m%20%2A%20%28vA%29%5E2%29%20%2B%201%2F2%2Am%2A%282vA%29%5E2%29%20%5D%7D)
2vf^2 / 5vA^2 = 0.35
In conclusion, The angle above the horizontal of the motion of mass A + B after the collision. as well as others
vf/vA= 0.94
2vf^2 / 5vA^2 = 0.35

Answer:
A. 2.41 s.
B. 24.3 m/s.
Explanation:
vf = vi + 2a*t
where, vf = final velocity
= 0 m/s
vi = final velocity
= 1.5 m/s
a = 9.8 m/s^2
A.
ti = 1.5/(9.8 * 2)
= 0.08 s
Vf^2 = Vi^2 + 2a*s
1.5^2 = 2 * 9.8 * s
S = 0.115 m
Time taken to drop into the water,
30.115 = 1.5*to + 4.9*to^2
to = 2.33 s
Total time taken = ti + to
= 2.33 + 0.08
= 2.41 s.
B.
Vo = 0 m/s
S = 30.115 m
Vf = ?
Using,
Vf^2 = Vo^2 + 2*a*s
= sqrt (2*9.8*30.115)
= 24.3 m/s.
The person that produces more power is Person A because its power is 50watts.
<h3>Calculation of power</h3>
For person A = Power= ,work done/ time
But work done = force × distance
person A = 100×3/6
= 300/6
= 50watts
For person B = 100×5/20
= 500/20
= 25watts
Therefore, the person that produces more power is Person A because its power is 50watts.
