Answer: True
Explanation: Injector orifice is the factor which describes the size of the opening of the injector .There are different pattern and size of the opening for the injector which affects the mixture of the chemical substance that is used for the production of the energy that is known as propellant.
The pattern and size of the orifice will define the variation in the amount of energy that could be produced.Thus the statement given is true.

Answer:
b. Discharging; anode; cathode
Explanation:
When discharging , it means the battery is producing a flow electric current, the lithium ions are released from the anode to the cathode which generates the flow of electrons from one side to another. When charging Lithium ions are released by the cathode and received by the anode.
Answer:
weight is 12.6 N
force is 4.05 N
Explanation:
given data
acceleration = 1.62 m/s²
radius = 1738 km
mass = 10 kg
distance = 1738 km
to find out
weight and force
solution
we apply here weight formula that is
weight = mass × acceleration ...................1
put here value
weight = 10 × 1.26
weight = 12.6 N
and
force = mass × An
force = 10 × 1.62 (1738/ 1738+1738)² = 4.05 N
so force is 4.05 N
Answer:
f=1.59 Hz
Explanation:
Given that
Simple undamped system means ,system does not consists any damper.If system consists damper then it is damped spring mass system.
Velocity = 100 mm/s
Maximum amplitude = 10 mm
We know that for a simple undamped system spring mass system
now by putting the values
100 = ω x 10
ω = 10 rad/s
We also know that
ω=2π f
10 = 2 x π x f
f=1.59 Hz
So the natural frequency will be f=1.59 Hz.
