Answer:
The detailed calculations are shown below;
Explanation:
a)The maximum acceleration of the particle:
It is seen that the maximum change in velocity is at the time between 8s to 10s.
Maximum acceleration: 
= 
= 10 m/
b) The deceleration of the particle
The velocity of particle is decreased after 10s so,
deceleration = - 
= - 6.67 m/
c)The total distance traveled by the particle = Area under the curve
= 
* 4*20 + 4*20 + * 2*20+ 2*20+ * 40*16
= 290 m
d)The average velocity of the particle = 
= 
= 18.12 m/s
Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]
Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35 [ tan 35 = 0.70 ]
In short, Your Answer would be 35 degrees
Hope this helps!
Answer:
The correct option is;
Technician A only
Explanation:
Leaks in the cooling system parts such as the radiator cap can be tested with a pressure operated hand pump by attaching the pump cap to the pump with an adaptor and apply pressure enough for there to be a release of pressure at the cap.
The pressure added to the system should be maintained for up to two minutes. If the pressure drops quicker, then there is likely to be leaks in the system
The freezing and boiling point of the coolant is measured with an antifreeze tester which carries the appropriate apparatus to measure the coolants freezing and boiling points.
Answer:
the armature and commutator
Explanation:
An electric generator converts mechanical energy to electrical energy. It is based on the principle that when a conducting coil rotates in the magnetic field, an electric current is generated.
The rotating part is known as Armature. Commutator is cylindrical in shape and connected to armature which rotates with it. It also connects the armature to the external circuit by brushes.
Slip rings are connected to armature coil to maintain an electrical contact with the brushes.
Answer:
Mecanical into electrical,kinectic and thermal energy
