What is a Blueprint
Blueprinting is the standard method used to copy large architectural and construction drawings. A blueprint used to consist of white lines on a blue background
What well-known mountain pass connects Pakistan and Afghanistan?
Khyber Pass
Why do objects float in liquids denser than themselves? What principle allows this to happen?
(You must answer both Parts of the question to receive full credit)
If an object were completely immersed in a liquid denser than it, the resulting buoyant force would exceed the weight of the object. This is because the weight of the liquid displaced by the object is greater than the weight of the object (since the liquid is denser). As a result, the object cannot remain completely submerged and it floats. The scientific name for this phenomenon is Archimedes Principle.
How much does a average car weigh?
About 2871 pounds
11 + sqrt(-4 + 6×4÷3)
13
What name is given to the northeast part of China?
Manchuria
How come in free fall you feel weightless even though gravity is pulling down on you? (ignore air resistance when answering this question).
The reason you feel weightless is because there is no force pushing against you, since you are not in contact with anything. Gravity is pulling equally on all the particles in your body. This creates a sensation where no forces are acting on you and you feel weightless. It would be the same sensation as if you were floating in space.
What do axes do?
(A highly rich and proper answer must be give to receive full credit)
Axles serve to transmit driving torque to the wheel, as well as to maintain the position of the wheels relative to each other and to the vehicle body
What is the slope of a line perpendicular to the line y = 6?
undefined
What country is also known as Persia?
Iran
What is the difference between centripetal acceleration and centrifugal force?
Centripetal acceleration is the acceleration an object experiences as it travels a certain velocity along an arc. The centripetal acceleration points towards the center of the arc.
How do cars Work?
A motor car engine is an Internal Combustion Engine (ICE). Energy is created by burning either diesel or petrol in a combustion chamber. In such an engine the energy is transferred from the pistons moving up and down at high speeds. This up-down motion is converted to a rotary motion through the crankshaft and axle.
What is the slope of a line perpendicular to the line x = -3?
0
What volcano exploded in 1883 with the force of 200 megatons of TNT?
Krakatoa
Two identical cars collide head on. Each car is traveling at 100 km/h. The impact force on each car is the same as hitting a solid wall at:
(a) 100 km/h
(b) 200 km/h
(c) 150 km/h
(d) 50 km/h
The answer is A, 100 km
