Starter
Explanation:
Turn the ignition switch to start and release the key immediately or you could destroy the starter.
The car starter is used to cause ignition in the internal combustion engine in order to fire the piston and cause mechanical motion. The starter is used to start the cyclic process of the internal combustion engine.
- Once the engine starts by igniting the starter, it is best to release it.
- The starter ensures that the spark plug is engaged and the motor is brought into work.
- If the ignition is still engaged, the process continues repeatedly and it can damage the starter of the car.

B
V= f x lambda
V= 5m/s
F = 10hz
Lambda = ?
5 = 10 x lamba
5 /10 = lambda
Wavelength =0.5
Constant acceleration of plane = 3m/s²
a) Speed of the plane after 4s
Acceleration = speed/time
3m/s² = speed/4s
S = 12m/s
The speed of the plane after 4s is 12m/s.
b) Flight point will be termed as the point the plane got initial speed, u, 20m/s
Find speed after 8s, v
a = 3m/s²
from,
a = <u>v</u><u> </u><u>-</u><u> </u><u>u</u>
t
3 = <u>v</u><u> </u><u>-</u><u> </u><u>2</u><u>0</u>
8
24 = v - 20
v = 44m/s
After 8s the plane would've 44m/s speed.
I believe the answer is Microwaves (just to clarify, not the oven). They're widely used for communications.<span />
