tan30° = BC/AB = x/125 = 1/3

=> x = 72.17 m

tan45° = BD/AB = y/125 = 1

Bihar Police Constable Mock Test - 7 - Question 12

A number is divided into two parts in such a way that 75% of the 1st part is 12 less than 30% of the 2nd part and 50% of the 2nd part is 56 more than 80% of the 1st part. What is the number?

Detailed Solution for Bihar Police Constable Mock Test - 7 - Question 12

Let the first part = x
Second part = y
30% of y – 75% of x = 12 ----(1)
50% of y – 80% of x = 56 ----(2)
0.60 × Eq2 – Eq1
75% of x – 48% of x = 0.60 × 56 – 12
27% of x = 21.60

30% of y – 75% of 80 = 12
30% of y = 72
y = 240
so number is there sum ie. x + y
So the answer = 80 + 240 = 320

Bihar Police Constable Mock Test - 7 - Question 22

Inertia

Detailed Solution for Bihar Police Constable Mock Test - 7 - Question 22
Inertia
Inertia is a fundamental concept in physics that describes an object's resistance to changes in its motion. It is directly related to the mass of an object and plays a crucial role in understanding the behavior of objects in motion.
Key Points:
- Sets objects in motion: Inertia is not responsible for setting objects in motion. It is the property of an object to resist changes in its state of motion. Once an external force is applied to an object, it overcomes its inertia and sets the object in motion.
- Causes changes in motion: Inertia is the reason why objects continue to move in a straight line at a constant speed in the absence of any external forces. However, if an external force is applied, the object's inertia resists the change, causing the object to accelerate, decelerate, or change direction.
- Is the result of a net force: Inertia is not directly the result of a net force. It is a property of matter and exists regardless of the presence or absence of external forces. However, when a net force acts on an object, it can overcome the object's inertia.
- Is directly proportional to the mass of an object: Inertia is directly related to the mass of an object. The greater the mass, the greater the inertia. This means that objects with larger masses are more resistant to changes in their motion compared to objects with smaller masses.
Therefore, the correct answer is option D: "is directly proportional to the mass of an object."
