pythagoras' theorem on right angled triangle. sides 125, 65
sqrt (125^2 +65^2)
Answer:
Average speed = 8.8 m/s
Average velocity = 8.8 m/s
Explanation:
From the question,
Avearge speed = 2πr/t................ Equation 1
Where r = 14 m, t = 10 s
Constant π = 22/7
Substitute this value into equation 1
Average speed = 2(22/7)(14)/10
Avearge speed = 8.8 m/s.
For a body moving in circular motion, The average speed and average velocity are equal.
Hence,
Average speed = 8.8 m/s
Average velocity = 8.8 m/s
A high thickness of a liquid
We have that the absolute pressure at the <u>bottom</u> of the tank is mathematically given as
Pabs=209.21Kpa
<h3>Absolute Pressure at the
bottom of the <em>tank</em></h3>
Question Parameters:
A 3-m-diameter vertical <em>cylindrical </em>tank is filled
with water to a depth of 11 m.
Generally the equation for the Absolute Pressure is mathematically given as
Pabs=Patm+pgh
Therefore
Pabs=101.3e3+(1000*9.81*11)
Pabs=209.21Kpa

Answer:
C. Both Technicians A and B
Explanation:
To loosen a fastener immediately especially if it is a rusted one we can follow these steps.
1. Tap the sides of the fastener so that the rust particle fall off.
2. These rust particles can be brushed off.
3. Spray the fastener with the penetrating oil.
4. Again tap the sides with a hammer to let the oil penetrate the inter-locked parts (threads in case of a nut and bolt).
5. Loosen the fastener after oil has penetrated.
Note: It should be kept in consideration that spraying alone won't do the job, tapping is essential to let the oil penetrate deep in to free the rusted parts.
