Answer:
Hope it helps..
Explanation:
Let n be the number of the vernier scale division which coincides with the main scale division. Rotate the vernier caliper 90° and repeat the steps 4 and 5 for measuring the internal diameter in perpendicular direction. To measure the depth, find the total reading and zero correction.

Answer:
Planet, in which he concluded that Planet X had a mass roughly seven times that of Earth—about half that of Neptune—and a mean distance from the Sun of 43 AU. He assumed Planet X would be a large, low-density object with a high albedo, like the giant planets
Explanation:
1.0m/s2 because net force and acceleration have a proprtional relationship
Answer:
The force of friction as a car drives around a corner at constant speed
Explanation:
The centripetal force is an external resultant force that is directed towards the center of circle which object is rotated and perpendicular to the direction of velocity.
The force of friction is always towards the center of the arc with car is turned and it is always perpendicular to the direction of motion.
We also can derive equation,
by considering friction as the centripetal force.
