The height of the Washington Monument is measured to be 170 m on a day when the temperature is 32.0°C. What will its height be in meters on a day when the temperature falls to −17.5°C? Although the monument is made of limestone, assume that its thermal coefficient of expansion is the same as marble's. (Assume the temperature of the entire monument changes from 32.0°C to −17.5°C. Enter your answer to at least five significant figures.) m??

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

You are an astronaut working on the international space station. accidentally, you let go of the handhold and drift off towards earth. the illustration, below, includes the details of your position (not drawn to scale). i’m a little stuck on the gravitational force felt by the astronaut from the iss. a little ?

How long will a plane have to fly continuously with 1100 miles per hour in order to cover the same distance as that from earth to the next star, proxima centauri?
