PAF Physics Quiz 13
1: Vernier constant is the _____ distance that can be measured by vernier calipers.
The correct answer is smallest. Vernier constant refers to the smallest measurement that can be made using the vernier scale.
2: A microgram is equal to _____ grams.
The correct answer is 10⁻⁶. A microgram is one millionth of a gram.
3: To measure the time between two incidents, a _____ is used.
The correct answer is stop-watch. A stop-watch is designed for measuring time intervals with precision.
4: If on a scale chosen to construct a vector, 3cm represents 75km/hr, then 5cm will represent:
The correct answer is 125km/hr. The scale is linear, so multiplying the number of centimeters by the rate gives the correct speed.
5: If Fx and Fy are the horizontal and vertical components of a vector F, then _____ represents the magnitude of F.
The correct answer is √(Fx² + Fy²). The magnitude of the vector is found using the Pythagorean theorem.
6: The _____ law of motion is also called the law of inertia.
The correct answer is first. The first law of motion is commonly called the law of inertia, which states that an object will remain at rest or in uniform motion unless acted upon by an external force.
7: The point at which all the weight of a body acts, is called the:
The correct answer is both B & C. In most cases, the center of gravity and the center of mass coincide for a uniform gravitational field.
8: If a turning force on a body is 100N and its moment arm is 0.1m then the torque acting on it will be:
The correct answer is 10 Nm. Torque is calculated as force multiplied by the moment arm length.
9: The gravitational acceleration is _____ to the distance from the centre of the earth.
The correct answer is inversely proportional. Gravitational acceleration decreases with the square of the distance from the center of the Earth.
10: If the velocity of a body is decreasing, the direction of acceleration will be:
The correct answer is opposite to the direction of velocity. Acceleration is in the direction opposite to velocity when the body is decelerating.
