The correct option is D.
Because <span>the distance that the honey flows is a dependent variable. Becuase the coefficient of viscosity is dependent on the velocity gradient (v/L). And, </span>Viscosity is very temperature dependent • It decreases with increasing temperature (in case of liquids). But, Viscosity of a gas increases with increasing temperature.
The final velocity of object 2 is: 3 m/sec
<h3>What is the conservation of mass?</h3>
According to the rule of conservation of mass, no atoms are created or destroyed during a chemical process. Instead, the atoms combine in a variety of ways to create goods. This explains why each element has the equal amount of atoms on both sides of an equation with balanced symbols.
According to conservation of mass,
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
Given that,
m₁ = 50 kg
m₂ = 75 kg
u₁ = 4 m/s
u₂ = -1 m/s
v₁ = -2 m/s
v₂ = ?
Now, putting the values,
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(50 × 4) + [75 × (-1)] = [50 × (-2)] + (75 × v₂)
or, 125 = -100 + 75 v₂
or, 75 v₂ = 225
or, v₂ = 3 m/sec.

#SPJ1
Explanation:
the unit of area is called a derived unit because it is made of two fundamental unit metre and metre.
The correct answer is C. microwaves, infrared, visible, gamma rays
Electromagnetic waves arranged in order of frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.
Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.
According to the Einsteins equation, E=hf, Energy is directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
