Which of the following can be used to measure accurately to three decimal places in centimeters? None of the above Meter rule Ruler Micrometer screw gauge Vernier calliper3. If we want to talk meaningfully about the velocity vector for an object at a certain moment in time, we must specify the object's instantaneous mass & speed mass & displacement speed & direction mass & direction4. In 3D space, we can define the magnitude of a vector in terms of the location of the coordinate origin right ascension & declination the length of the line segment representing it celestial latitude & longitude5. What would happen if the earth suddenly stopped moving in its orbit around the sun, but nothing else changed? The earth would remain fixed at the spot Nobody knows The earth would fly out of solar orbit The earth would fall into the sun6. The power source of a ticker-timer vibrates 40 times in one second. If the ticker-timer made 200 dots during an experiment, determine how long the experiment lasted. 25 seconds 45 seconds 15 seconds 5 seconds7. Which of the following parameters manifests itself as a vector quantity? velocity mass temperature visible-light intensity8. An object moves 4m eastwards and then 3m southwards. Its displacement from its original position is 5m SE 1m SE 7m SE 12m SE9. Which of the following are scalar quantities?I. MomentumII. EnergyIII. Mechanical advantageIV.

To determine the weight of an object, you could None of the above Any of the above Find the force necessary to give it a certain acceleration Use a beam balance Use a spring balance12. If the tape of a ticker-timer shows dots equally spaced at 1cm apart and the vibrator makes 50 dots per second, what is the speed of the tape in meter per second? 5.0m/s 0.5m/s 0.02m/s 50m/s 0.1m/s13. Which of the following is a fundamental unit? Newton Ampere Watt Joule14. We can express electrical current in terms of charge carriers per cubic meter per square meter per kilogram per second15.

The length of a ten tick is 8cm and it is covered in 1/5 seconds. Find the velocity of the body. 16cm/s 1.6cm/s 0.02cm/s 40cm/s23. A vernier scale was formed by dividing a length of 19mm into 20 equal parts. If the vernier scale is used with a main scale marked in mm, what is the smallest distance that can be measured? 0.5mm 0.05mm 0.005mm 0.001mm 0.1mm24. When we talk about steradians, we talk about Solid angular measure gravitational acceleration surface area volume25. The values of p, q, and r respectively in the expression MpLqTr for the universal gravitational constant G are -1, 3, -2 2, -3, -2 -2, -1, 3 -1, 2, -326 out of 25Time is Up!
