The answer is true a convex lens can produce a real image but not a viral image
Answer:
The value of gauge pressure at outlet = -38557.224 pascal
Explanation:
Apply Bernoulli' s Equation
+
+
=
+
+
--------------(1)
Where
= Gauge pressure at inlet = 3.70105 pascal
= velocity at inlet = 2.4 
= Gauge pressure at outlet = we have to calculate
= velocity at outlet = 3.5 
= 3.6 m
Put all the values in equation (1) we get,
⇒
+
=
+
+ 3.6
⇒ 0.294 =
+ 0.6244 + 3.6
⇒
= 0.294 - 0.6244 - 3.6
⇒
= - 3.9304
⇒
= - 38557.224 pascal
This is the value of gauge pressure at outlet.

Distance travelled by the truck is ~
And it's displacement is ~

See the diagram in attachment for reference ~
Let O be the initial point, It travels 60 km towards west till point B and then 80 km towards north till point P and returns to initial point O in a straight line, now as we can observe here, it forms a right angled Triangle.
The measure of two legs is 60 km and 80 km, let's find the hypotenuse ~
According to Pythagoras theorem ~
hypotenuse² = sum of squares of other two legs
that is ~
So, the distance between the point A and O is 100 km
Now, The total distance is equal to the distance covered through actual path that is ~
And displacement is the distance between the final point and initial point, but since the truck returns to the point from where it started the journey, so the final and initial point is same therefore displacement is equal to 0.
Wind and water is the answer

Diesel engines are relatively cheaper than most other commercial engines. Combustion in the engine is started by ignition of high temperatures of the fuel. The best answer is B. glow plug. The glow plug is the device that aids this combustion-ignition process most especially for cold weather. Of course, heat is needed to start up the engine. The glow plug is this heating element as aid in starting up.
