Some important and basic points:
Unit of time is second (s).
Unit of mass is kilogram (kg).
Unit of distance/displacement is meter (m).
P.S. Displacement and distance are nearly same things, their unit is same.
Speed/velocity = distance/time
So, its unit is m/s.
Acceleration = (final velocity-initial velocity)/time.
So, its unit is m/s² or m.s^-2
We know from the formula that,
Force = mass × acceleration
=> F = ma
Putting units:
Newton = kg.m/s² or kg.m.s^-2 _____(1)
Putting dimensions:
Newton = M.L.T^-2
________________________
We know from the formula that,
Work = force × displacement
=> W = Fs
Putting units:
Joule = Newton.m
=> Joule = kg.m.s^-2.m [from (1)]
=> Joule = kg.m².s^-2 ______(2)
Putting dimensions:
Joule = M.L².T^-2
________________________
We know from the formula that,
Power = work/time
Putting units:
Watt = joule/s
=> Watt = kg.m².s^-2/s [from (2)]
=> Watt = kg.m².s^-3 ______(3)
Putting dimensions:
Watt = M.L².T^-3
________________________
We know from the formula that,
Horsepower = 746 watt
=> Horsepower = 746kg.m².s^-3 [from (3)]
Putting dimensions:
Horsepower = 746M.L².T^-3
Hope it helps!!The dimension of Watt, Newton and horsepower are ML²T⁻³, MLT⁻² and ML²T⁻³ respectively
Units and dimensionUnits are measure of a quantity. Dimensions are derived from the units. Gi
Force = mass × acceleration
For Newton:
Another representation for unit of Newton is kg.m/s². Writing in terms of the dimension
Newton = MLT⁻²
For Watts;
The unit of Watt is also kg.m².s⁻²/s which is equivalent to kg.m².s⁻³
In terms of dimension
Dimension of Watt = ML²T⁻³
For Horse power:
The unit of horse power is kg.m².s⁻³
Dimension of horsepower = ML²T⁻³

Reducing the CFM through the evaporator will cause the amount of moisture removed from the air to ____________________. A. stay the same B. decrease C. increase
Answer:
C. increase
Explanation:
Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.
On a related note, particulate pollution is a form of pollution that is responsible for the degradation of the environment.
Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air. Other forms of particle pollution includes space debris and marine debris. Some examples of particulate pollution are dusts, soot, dirt, smoke, etc.
Generally, when cubic feet-per-minute (CFM) are reduced through the use of an evaporator, it will cause the amount of moisture removed from the air to increase.
The image shows a reconstruction of a pyramid with a square base. What is the best estimate for the volume of the pyramid?
A.
1,460,040 m3
B.
2,433,400 m3
C.
4,380,120 m3
D.
7,300,200 m3
Answer:
B 2,433,400 m3
Hope that helped you
Based on the calcualtions, the best estimate for the volume of the pyramid is: B. 2,433,400 m³.
How to calculate the volume of a pyramid.Mathematically, the volume of a pyramid is calculated by using this formula:
[tex]Volume = \frac{1}{3} \times base\;area \times height[/tex]
For the base area:
The area of a square is given by:
A = S²
A = 230²
A = 52,900 m².
Now, we can determine the volume:
Volume = 1/3 × 52,900 × 138
Volume = 2,433,400 m³.

Question 10: What is a K-turn?
Answer:
The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn.

Question 74
Which of the following would be required when towing a person on water skis
behind a PWC rated for two people?
A
power winch
B
reboarding ladder
С
rearview mirror (at least four inches by four inches)
D
rectangular red flag with a white diagonal stripe
Support
Answer:
C). rearview mirror (at least of four inches by four inches).
Explanation:
A 'rearview mirror' would be needed in case one is required to pull an individual on water skis after a PWC(personal watercraft) that is rated for carrying two persons only. This wide-angle mirror for rearview would allow the operator to monitor the person who is being towed constantly along with riding the ski at the same time. It is considered illegal to tow a person on a vessel without having a rearview mirror and at the same time, the limited capacity must also be followed strictly. Hence, option C is the correct answer.
What is a differential in cars and what does it do?
Simply put, a differential is a system that transmits an engine's torque to the wheels. The differential takes the power from the engine and splits it, allowing the wheels to spin at different speeds. ... Turn it around a corner and you'll have no issues, as each wheel is able to turn independently from the other.

find the value of resistor having 4 colour band yellow, violent, orange,silver
Answer:
The value of resistance of a resistor having four colour bands in the order yellow, violet , orange and silver is 47000 ± 10%
Answer:
Explanation:
yellow = 4
violet = 7
orange = 3 zeros
silver = 10% tolerance.
So the value of the resistor is
47000 +/-10%
10% means 4700 ohms either side of 47000 so that means
42300 < x < 51700
Usually a ten % tolerance is more than adequate for most applications.
