You find signs of an ancient civilisation and with some effort discover what the the base units for theirsystem of units are and how they are related to more familiar units:Mass: 1 pebble = 0.1234 kgTime: 1 moment = 11.21 sLength: 1 leg = 1.203 mAssume that the ancient civilisation constructed derived units in a similar fashion to what we do inthe SI system. What would the equivalent of 1 Newton be in this system of units?tel

When the Earth passes a planet such as Mars, the planet appears to move backward for a time, a phenomenon known as retrograde motion. Ancient astronomers believed that the Earth did not move and that the planets moved around the Earth. They also believed that uniform circular motion was perfect and that heavenly objects such as planets exhibited this perfect motion. How do you suppose ancient astronomers accounted for retrograde motion? Include a sketch with your explanation.
CASE STUDY On planet Betatron, mass is measured in bloobits and length in bots. You are the Earth representative on the interplanetary commission for unit conversions and find that 1 kg = 0.23 bloobits and 1 m = 1.41 bots. Express the density of a raisin (2 103 kg/m3) in Betatron units.
Newton's law of universal gravitation is represented by F=GMm/r2 Here F is the magnitude of the gravitational force exerted byone small object on another, M and m are the masses of theobjects, and r is a distance. Force has the SI units kg.m/s?What are the SI units of the proportionality constant G?
Please solve for items c and d In the future, we may encounter a civilization from another planet. They will not use the SI or AE systems of units. Suppose we meet aliens who use the Zerf as a unit of mass and the Spund as a unit of force. One Spund is the weight of a mass of one Zerf on the surface of Mars. The gravitational acceleration on Mars is 3.7 m/s2.a. What is gc in the alien system of units? Be sure to include the numerical value and the units.b. How much would a 350 Zerf object weigh on the surface of Mars, in Spunds?c. How much would a 350 Zerf object weigh on the surface of the Earth, in Spunds?d. To which system of units is the Zerf-Spund system most similar, SI or AE?
I am a little confused on this question , please help. Thank you for your time! I'm supposed to solve using Scientific Notation and stating the correct units in answer. I have attached the problem .Please view attachment before answering. Thank you again!
Newton's law of universal gravitation can be expressed by the equation F = G Mm r2 , where F is the gravitational force, M and m are masses, and r is a length. Force has the SI units kg · m/s2. What are the SI units of the proportionality constant G?
Newton’s law of universal gravitation is represented byF = G Mm r 2where F is the gravitational force, M and m are masses, and r is a length. Force has the SI units kg · m/s 2 . What are the SI units of the proportionality constant G?
Alexa's hair grows with an average speed of 3.5 × 10–9 m/s. How long does it take her hair to grow 0.50 m? Note: 1 year = 3.156 × 107 s.
The maximum running speed (S) in km/hr and the corresponding body mass (m) in kg were determined for 55 different species of mammals. An empirical relation was determined to be: S[km/hr] = 5.7 (m[kg])2 . Note: The notation in this equation means, “inserting the mass (m) in units of ‘kg’, automatically calculates the maximum running speed (S) in units of ‘km/hr’. ” (a) What are the implied units for the “5.7” factor? Hint: recall that relations between physical quantities must be dimensionally consistent, and the chosen units must in turn be consistent with the dimensionality. (b) Re-write the equation so that it gives the maximum speed in units of “m/s” for a given body mass in “g”. Show all relevant details. If done correctly, you will need to use at least one unit conversion factor.
