- Question
Which of the following is a Heterogeneous Mixture?
Options- A. Air
- B. Table salt
- C. Soda
- D. Brass
- Correct Answer
- Soda
ExplanationHere Soda is a Heterogenous Mixture.
A Heterogeneous Mixture is a mixture having a non-uniform composition i.e, the mixture contains components in different phases. Using various means, the parts in the mixture can be separated from one another.

Correct Answer: a safety device
Correct Answer: 4 C
Correct Answer: frequency is same but the wavelength is smaller in water than in air
Correct Answer: the red ray
Explanation:
Red is deviated the least and violet the most
Correct Answer: 2N
Explanation:
Weight is mass x g. Since mass is constant and g is only of that on the earth. The weight on the moon is only of that on the earth.
Therefore 2N i.e (b) is the answer.
Correct Answer: Moving
Explanation:
In physics, we know that the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Hence, An object that has kinetic energy must be in motion i.e, moving.
Correct Answer: Flint glass
Correct Answer: Energy tranfer takes place either by means of Heat or Work only in Thermodynamics Heat :: Heat Energy is defined as Energy that can be transferred due to temperature change Whereas Thermal Energy :: Thermal Energy is the Internal Energy stored in the system maintained at a certain Temperature
Correct Answer: B2+ is a Paramagnetic The filled orbitals are ?(1s)2 2, ??(1s)2 2, ?(2s)2 2, ??(2s)2 2 The half-filled orbitals are ?(2px x) and ?(2py y) Since it posses 2 unpaired electrons, it is Paramagnetic in nature
Correct Answer: Voltage
Explanation:
Electrical Pressure is also called as Voltage. Voltage is measured in Volts.
Volt : A unit of electrical pressure or Voltage is called Volt.
One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance.
Voltage is also referred to as Electromotive Force or Electrical Potential or Electrical Pressure.
