Upto what decimal place does a vernier caliper count the reading?
-
Up to two decimal places
-
Up to three decimal places
-
Up to 1 decimal place
-
Up to seven decimal places
Correct Answer
A. Up to two decimal placesExplanation
A vernier caliper is a measuring instrument that is used to measure linear dimensions with high accuracy. It consists of a main scale and a sliding vernier scale. The main scale typically has markings up to one decimal place, while the vernier scale allows for more precise readings. In this case, the correct answer is "up to two decimal places" because the vernier scale provides an additional digit of accuracy beyond the main scale.Rate this question:

What is the specific heat capacity of water?
-
5.8 kg\J degree C
-
4200 kg\J degree C
-
934 kg\J degree C
-
4132 kg\J degree C
Correct Answer
A. 4200 kg\J degree CExplanation
The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of a unit mass of the substance by one degree Celsius. In the case of water, the specific heat capacity is 4200 kg/J degree C. This means that it takes 4200 joules of energy to raise the temperature of 1 kilogram of water by 1 degree Celsius.Rate this question:

What is the formula for the calculation of time period?
-
T=1\g
-
T=1\r
-
T=1\f
-
T=1\l
Correct Answer
A. T=1\fExplanation
The correct answer is t=1\f. This formula represents the calculation of time period. The "t" represents the time period, and the "1" in the numerator indicates that it is a constant value. The "\f" in the denominator represents the frequency, which is the number of cycles or oscillations per unit of time. Dividing 1 by the frequency gives us the time period.Rate this question:

What is the relation between one calorie and joules?
-
1 Cal = 4.184 Joules
-
1 Cal= 100 Joules
-
1 Cal= 1034 Joules
-
1 Cal= 7.896 Joules
Correct Answer
A. 1 Cal = 4.184 JoulesExplanation
One calorie is equivalent to 4.186 joules. This means that if we have 1 calorie of energy, it can also be expressed as 4.186 joules of energy.Rate this question:

What is a positive ion known as?
-
Cation
-
Anion
-
Cathode
-
Anode
Correct Answer
A. CationExplanation
A positive ion is known as a cation. Cations are formed when an atom loses one or more electrons, resulting in a net positive charge. They are attracted to the cathode in an electrolytic cell and are typically smaller in size compared to their parent atoms. Cations play a crucial role in various chemical reactions and are often involved in the formation of ionic compounds.Rate this question:

Scalar quantities have __________________ but no ________________
Correct Answer
magnitude, directionExplanation
Scalar quantities have magnitude but no direction. Scalar quantities are physical quantities that can be completely described by their magnitude or numerical value alone. They do not have any associated direction. Examples of scalar quantities include mass, temperature, time, and speed.Rate this question:

Displacement can be zero even if the distance travelled is not 0?
-
True
-
False
Correct Answer
A. TrueExplanation
Displacement is a vector quantity that refers to the change in position of an object. It takes into account both the distance traveled and the direction of the movement. Therefore, it is possible for the distance traveled to be nonzero while the displacement is zero. This can occur when an object moves in a closed loop or returns to its original position. In such cases, the total distance traveled may be nonzero, but since the starting and ending positions are the same, the displacement is zero.Rate this question:

If more current is applied to a solenoid then
-
Its magnetic field increases
-
Its magnetic field decreases
-
No effect
-
It gets hotter
-
None of the above
Correct Answer
A. Its magnetic field increasesExplanation
When more current is applied to a solenoid, the magnetic field increases. This is because the magnetic field produced by a solenoid is directly proportional to the current passing through it. As the current increases, more magnetic field lines are generated, resulting in a stronger magnetic field. Therefore, the correct answer is that the solenoid's magnetic field increases.Rate this question:

In kinematics, if an object's velocity is constant, then its acceleration must be zero.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false. In kinematics, acceleration is the rate of change of velocity. If an object's velocity is constant, it means there is no change in speed or direction. However, this doesn't imply that the object's acceleration is zero. Acceleration can be zero only if the velocity remains constant, not necessarily at zero.Rate this question:
