Answer:

Option (C) is correct.

Explanation:

Speed of an object is defined as the distance covered per unit time. Speed is a scalar quantity It is composed only of the magnitude but the direction is absent. Mathematically, it is given by :

v=\dfrac{d}{t}

d = distance

t = time

So, the correct option is (c) " distance per time ". Its unit can be miles per hour or meter per second.

An open organ pipe is 2.46 m long, and the speed of the air in the pipe is 345 m/s.
lukranit [14]

Answer:

Fundamental frequency is 70.12 m

Explanation:

For an open organ pipe, the fundamental frequency is given by :

f=\dfrac{nv}{2l}

n = 1 for fundamental frequency

v is speed of sound in air, v = 345 m/s

l is length of open organ pipe, l = 2.46 m

Substituting values in above formula. So,

f=\dfrac{1\times 345}{2\times 2.46}\\\\f=70.12\ Hz

So, the fundamental frequency of this pipe is 70.12 m.

What is the mode of heat transfer from drying of wet hot plate in atmosphere​
SashulF [63]

Answer:

It's convection

Explanation:

As the hot place transfers heat to the liquid substance, it becomes less dense and rises to the surface given rise for cooler molecules directly above to fall and so undergoes the same circle. In the process the less dense particles are so light that it's swayed into the atmosphere. In the process drying is ensued.
