A body starts moving from rest and attains the acceleration of 0.5 m/s2. Calculate the

velocity at the end of 3 minutes and also find the distance travelled by it during that

time.

If you were to compare three stars with the same surface temperature, with one star being a giant, another a supergiant, and the third a main-sequence star, how would their radii compare to one another?

Suppose a runner completes one lap around a 400-m track in a time of 50 s. Calculate the average speed of the runner.

An atomic nucleus may contain several protons, each of which has a positive charge. Which type of force allows the nucleus to be stable?

As a train accelerates uniformly, it passes successive 5-kilometer markers while traveling at velocities 10 m/s and 25 m/s. what is the velocity in km/h when it passes the next marker? round to nearest tenth of a km/h.

Eric has just had a sandwich that contained the equivalent of 1.80 mol of glucose the standard molar entropy of reaction is 182 j k-1 mol-1.

Why is it useful to calculate average speed?

Which describes freefall

Suppose you were examining a pulsing radio signal from a stellar remnant in a distant part of the Milky Way.

Which pair of properties do all liquids have? A) Fixed volume; no definite shape B) Conducts electricity well; compressible C) Compressible; brittle D) Good conductor of heat; takes shape of container

0.2000 kg of water at 20.00°C is contained in a 0.1000-kg copper container. The container is shaken vigorously for 10.00 minutes to cause the temperature to rise to 22.00°C. Calculate the work done on the system and the heat supplied to the system.
