Chapter S2, Problem 25EAP
Does It Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.
25. If you see someone's time running slowly in a different reference frame, that person must see your time running fast.

1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth
at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to
the earth. You may assume that both clocks can measure time accurately to many significant
digits.
a. Will the two clocks still be synchronized after one year? Explain your reasoning.
b. Imagine that the speed of light was much slower than its actual value. How would the results
of this experiment change if the speed of light was only twice the average speed of the
satellite? Explain your reasoning, using a calculation.
QUESTION 2

2 The maximum speed in SLEX is 100 km/H. How many miles will you travel per minute?
3. You are doing a project by mixing some concrete, and you've calculated according to the
directions that you need six gallons of water for your mix. If you use the two-liter empty bottle of soda to measure your water, how many times will you need to fill it?
4. The density of seawater is 62.8 pounds/feet. How much is this density in kg/m³
5. You want to check if the gold ring that your fiancée gave you is a "real gold". Upon weighing. the mass of the ring is 9.5 grams and using the water displacement method to determine the volume, and it overflow 0.6 mL. What is the density of your gold ring? Is the ring a real gold?
Accepted density of gold is 19300 kg/m³.

- Head or tails Context To play heads or tails, you toss a 25 cent coin in the air straight up. To make sure you don't hit the ceiling, you want to predict the maximum height the room will reach, taking into account uncertainty as well. Constraints The initial height of your hand is fixed, and accompanied by uncertainty;The gravitational acceleration used will be ?=(9.81±0.01)m/s^2;The movement is perfectly vertical. Modelization Start by modeling the situation by writing an equation that calculates the maximum height reached by the coin (ymax) based only on the initial speed of the throw as well as the height of your hand when you throw the coin. Then test your model with the following values: Height of your hand = (1.01±0.02)m; Speed of the coin when it leaves your hand = (2.17±0.04)m/s;arrow_forwardWrite an explanation or narration about the given problem why the problem got these answers shown in the photos.
