Answer:
The correct option is d ( Neither A nor B)
Explanation:
Technician A made 2 mistakes in his statement.Firstly the tire is self supporting not self sealing.
Secondly, this tire does not provide permanent sealing of punctured area option a is incorrect.
This self-supporting tire after being affected with complete air leakage can temporarily bear the load of the car and avoid rolling over a distance of 80 km at a maximum speed of 55 mph. Here is what technician B suggested incorrectly as the tire after being.Here the technician B suggested incorrectly as the tire after being affected with puncture can not travel at any speed so option B is wrong
Since option a and b are incorrect and c is invalid.
Answer:
SPCA factor
Single payment compound amount factor.
Total amount pay A = $24,230.95 (Approx)
Interest paid = $4,230.95 (Approx)
Explanation:
Given:
P = $20,000
n = 6 year
r = 3.25%
Find:
Total amount pay A
Computation:
A=p(1+r)ⁿ
A=20,000[1+3.5%]⁶
A=20,000[(1.0325)⁶]
Total amount pay A = $24,230.95 (Approx)
Interest paid = $24,230.95 - 20,000
Interest paid = $4,230.95 (Approx)
Answer:
A: density and gravity
Explanation:
The Froude Number is defined as a dimensionless parameter that measures the ratio of the force of inertia on an element of fluid to the weight of the fluid element. In simple terms, it's the force of inertia divided by the gravitational force.
Froudes number is usually expressed as;
Fr = v/√(gd)
Where;
Fr = froude number
v = velocity
g = gravitational acceleration = specific weight/density
d = depth of flow
Now, to calculate the corresponding speed and force in the prototype, it means we have to use equal froude number and thus this will mean that it has to be dominated by gravity and density.
Answer:
Option C
Both A and B
Explanation:
Both technicians are right about what they say about wire brushes. wire brushes are usually made up of steel wire bristles. however, when high RPMs are involved, it is better to get some special types of brushes for that purpose. This is because the heat generated at high RPMs is great, and most times, damages the brush after prolonged use if it is not specially built for such speeds.
In addition that, some wire brushes have plastic hubs which help support the bristles and is usually attached to the motor.
Considering these, we can say that the Two technicians are right
Answer:
1.4 mL
Explanation:
Given that:
volume of alcohol 
= 500
Temperature change ΔT = (30° - 5°)C
=25° C
The increase in volume ΔV = 
= 1.4 mL
