Explanation

Statement of the given problem,

A mixture of 17 parts of A, 3 parts of B, and 4 parts of C weigh 72 ounces. How many ounces of substance B are in this mixture?

From above data we get following relations,

A/17 = B/3 = C/4 = k (say) …… (1)

A + B + C = 72 …… (2)

From (1) & (2) we get,

17*k + 3*k + 4*k = 72 or k = 72/24 = 3 …… (3)

From (1) & (3) we get,

B = 3*3 = 9 (ounces) [Ans]

Explanation

A path is a little road (often so small that only one person can use it at a time),

while a highway is a large road with room for thousands.

A brook and a river have a similar size relationship.

Explanation

 Electromagnetic force is a scalar quantity.

Force is defined as the product of mass and acceleration and force is a vector quantity.

This is the pair in which one physical quantity is scalar and the other is a vector.

Explanation

Aerophobia is an extreme fear of flying.

People with aerophobia might feel intense anxiety before or during a flight

while

Anthophobia is the fear of  floral

Febriphobia is the fear of fever.

Laliophobia is a fear of speaking

Nyctophobia is the fear of  Darkness.

Explanation

Aerodromes are one of the most important links in the civil aviation network.

They are the key interface between the passengers and the aircraft, and the location where every flight begins and ends

Explanation

The kinetic energy is mathematically expressed as K. E=12mv2,

where m is the mass of the body and v is the velocity with which the body is moving

If velocity v is doubled, the kinetic energy becomes four times as kinetic energy is directly proportional to the square of velocity.

Explanation

In circular motion, the centripetal force  𝐹 required to keep an object moving in a circular path is given by the formula:

𝐹= 𝑚 𝑣^2/ 𝑟

Where:

m is the mass of the object,

v is the velocity of the object,

r is the radius of the circular path.

If the velocity v is doubled, the centripetal force becomes:

F ′ =  m(2v) ^2/r = 4mv ^2/r =4F

This means that if the velocity is doubled, the force will be four times the original, not twice or half the original.

Therefore, neither of the options provided is correct.

Explanation
