- A rectangular box has dimensions….. SEE PHOTO. Please also answer #7 which goes along with #6..................... The dimensions of the quantity kinetic energy, designated by K, are kg m/s, It can be written in terms of the momentum p and mass m as K = 2m (a) What are the units of momentum in terms of fundamental SI units? (Use the following as necessary: kg, m, and s.) [P) - (b) Force is measure in units of newtons, N, where 1N- 1 kg m/s. What are the units of momentum p in terms of a newton and another fundamental SI unit? (Use the. following as necessary: N, m, and s.) [P) = (c) What If? Physicists often measure the momentum of subatomic particles moving near the speed of light in units of MeV/c, where c is the speed of light, and 1 Mev = 1.6 x 101 kg m/s. Based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental SI units? What are the units of momentum for a high-speed subatomic particle in terms of a newton and another fundamental SI unit? [P] -44. Let A=(2 m)î +(6 m)j – (3 m)k and B = (4 m)î +(2 m)† +(1 m)k.

- In one of the videos I said that a typical American household uses energy at a rate of about 10,000 joules per second. A shorthand unit for this would be "10 kilowatts". Using energy at this rate costs about $1.50 per hour (this is not quite right, as it assumes that all the energy is electrical energy, which is relatively cheap, but let's go with this for an estimate). How much does this energy usage cost for a year?A = 2 X 1025, B = 4.5 X 10-10, C = 3 X 10-6. AB/C = ? (2) ACB = ? (3) The Moon is approximately 400,000 km from the Earth. An atom of a certain element has a diameter of 4 X 10-8 cm. Given 1 km = 1,000 m and 1 m = 100 cm, about how many atoms of this element can be lined up between Earth and Moon? (4) A spherical planet has a radius of 2,000 km and a mass of 1025 kg. Calculate its density (mass/volume) in kilograms per cubic meter. (5) How many of the atoms in Question (3) can fit within a spherical planet with a diameter of 2 X 104 km? (6) An asteroid’s radius is 200 m and its distance from Earth is 107 km. What angle in degrees (θ) will it subtend? Use the equation θ = 57 (diameter) / distanceGiven A= (-3i+7j-4k) B= (6i-10j+9k), calculate A X B.
- the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom. What is the approximate density, in kilograms per cubic meter, of a nucleus?Just do from (e) till ( j)What is the square root of 1023? (Hints: 10 is an integer number. Integer numbers are exact, they don't have any uncertainty. The result however is going to be a real number. Computers approximate real numbers using floating point numbers. Floating point numbers have a given number of significant figures or digits. LON-CAPA typically expects 3, 4 or 5 digits. 2 or 1 is not enough, 6 or more is too many. Very large or very small numbers are expressed in scientific or exponential notation like the number above. Numbers in scientific notation are entered to computer software - like LON- CAPA as 1.23E15 or 1.23e15, for example; and 1.23E-15 or 1.23e-15, if the exponent is negative. If both the number and the exponent are negative, then you type -1.23E- 15 or -1.23e-15. On calculators the button is usually labelled as 'EE', but 'E' or 'EEX' or 'Exp' are also possible.)
- A person walks 4 m to the park, then he walks 8200 km in the park then he returns back to home after grocery shopping and covers 720 cm, how much total distance that person covers in m?In the answer, it gives a formula f-ff=m(0) and afterwards simplies into 120 - ff = 0 and further into ff=120N. My question is how do you not have to divide by 0 to finish the equation if that makes sense. To simply further why are we able to ignore the m(0) portion?Please help with this question, it’s not 0, 3, or -2.33. Thank you so much!
