A furlong is 220 yd; a fortnight is 14 d. How fast is 1 furlong per fortnight (a) in \(\mu \mathrm{m} / \mathrm{s} ?\) (b) in km/day?

Short Answer

Expert verified
1 furlong per fortnight can be converted to (a) micrometers per second (µm/s) and (b) kilometers per day (km/day) as follows: (a) Using the conversion steps mentioned above, we can calculate the speed in µm/s: speed = (220 * 0.9144 * 1,000,000) / (14 * 24 * 60 * 60) µm/s = 160.9344 µm/s (b) Similarly, when converting to km/day, we calculate the result: speed = (220 * 0.9144 * 0.001) / 14 km/day = 0.0144 km/day So, 1 furlong per fortnight is approximately 160.9344 µm/s or 0.0144 km/day.

Step by step solution

01

Calculate the speed in meters per second

First, we need to convert 1 furlong per fortnight to meters per second. We are given that 1 furlong is equal to 220 yards, and 1 fortnight is equal to 14 days. 1 furlong = 220 yd 1 fortnight = 14 d Using conversion factors for yards to meters and days to seconds, we can find the speed in meters per second. The conversion factors are: 1 yard = 0.9144 m 1 day = 24 h = 24 * 60 * 60 s Now calculate the speed in meters per second: (1 furlong per fortnight) * (220 yd per furlong) * (0.9144 m per yard) / (14 days per 1 fortnight) * (24 h per day) * (60 min per h) * (60 s per min) After canceling out the units, we get: speed = (220 * 0.9144) / (14 * 24 * 60 * 60) m/s
02

Convert to micrometers per second (µm/s)

Now to convert the speed in meters per second to micrometers per second, we use the following conversion factor: 1 m = 1,000,000 µm So, we multiply the speed in meters per second by 1,000,000 to get the speed in micrometers per second: speed * 1,000,000 = (220 * 0.9144 * 1,000,000) / (14 * 24 * 60 * 60) µm/s Calculate the result to obtain the speed in µm/s.
03

Convert to kilometers per day (km/day)

For the final conversion, we need to find the speed in kilometers per day. We can use the following conversion factors: 1 m = 0.001 km 1 day = 24 h = 24 * 60 * 60 s Now, we multiply the meters per second speed by the appropriate conversion factors: speed * 0.001 km/m * (24 * 60 * 60) s/day = (220 * 0.9144 * 0.001 * 24 * 60 * 60) / (14 * 24 * 60 * 60) km/day We can cancel some terms and calculate the result: speed = (220 * 0.9144 * 0.001) / 14 km/day Calculate the final speed in km/day.

A linear plot of speed versus elapsed time has a slope of $6.0 \mathrm{m} / \mathrm{s}^{2}\( and a vertical intercept of \)3.0 \mathrm{m} / \mathrm{s} .$ (a) What is the change in speed in the time interval between \(4.0 \mathrm{s}\) and \(6.0 \mathrm{s} ?\) (b) What is the speed when the elapsed time is equal to 5.0 s?
The Space Shuttle astronauts use a massing chair to measure their mass. The chair is attached to a spring and is free to oscillate back and forth. The frequency of the oscillation is measured and that is used to calculate the total mass \(m\) attached to the spring. If the spring constant of the spring \(k\) is measured in \(\mathrm{kg} / \mathrm{s}^{2}\) and the chair's frequency \(f\) is \(0.50 \mathrm{s}^{-1}\) for a \(62-\mathrm{kg}\) astronaut, what is the chair's frequency for a 75 -kg astronaut? The chair itself has a mass of 10.0 kg. [Hint: Use dimensional analysis to find out how \(f\) depends on $m \text { and } k .]$
A typical virus is a packet of protein and DNA (or RNA) and can be spherical in shape. The influenza A virus is a spherical virus that has a diameter of \(85 \mathrm{nm}\) If the volume of saliva coughed onto you by your friend with the flu is \(0.010 \mathrm{cm}^{3}\) and \(10^{-9}\) of that volume consists of viral particles, how many influenza viruses have just landed on you?

Three of the fundamental constants of physics are the speed of light, \(c=3.0 \times 10^{8} \mathrm{m} / \mathrm{s},\) the universal gravitational constant, \(G=6.7 \times 10^{-11} \mathrm{m}^{3} \cdot \mathrm{kg}^{-1} \cdot \mathrm{s}^{-2},\) and Planck's constant, \(h=6.6 \times 10^{-34} \mathrm{kg} \cdot \mathrm{m}^{2} \cdot \mathrm{s}^{-1}\) (a) Find a combination of these three constants that has the dimensions of time. This time is called the Planck time and represents the age of the universe before which the laws of physics as presently understood cannot be applied. (b) Using the formula for the Planck time derived in part (a), what is the time in seconds?

The average depth of the oceans is about \(4 \mathrm{km}\) and oceans cover about \(70 \%\) of Earth's surface. Make an order-of-magnitude estimate of the volume of water in the oceans. Do not look up any data in books. (Use your ingenuity to estimate the radius or circumference of Earth.)
