We would like to be able to make meaningful interpretations of variations in the acceleration due to gravity, g, as small as 0.1 mgal. How accurate must our knowledge of the latitude of our gravity stations be? (A “gravity station" is just a location at which you make a gravity measurement.) You can assume your latitude is 45°.

Can you please do 5-8. Thank you

The quantities v, K, U, and L all represent physical quantities characterizing the orbit that depend on radius R. Indicate the exponent (power) of the radial dependence of the absolute value of each. Express your answer as a comma-separated list of exponents corresponding to v, K, U, and L, in that order. For example, -1,-1/2,-0.5,-3/2 would mean v ∞ R¹, K & R-¹/2, and so forth.

expressed as length { in meters seconds squared, or . h divide out and T = VT2. The factor 2T has no units so d in the analysis. 10. The period of rotation of the Sun is 2.125 x 106 seconds. This is equivalent to 2.125 (2) ms (1) us (3) Ms (4) Ts 11. Human hair grows at the rate of 3 nanometers per second. This rate is equivalent to (1) 3 x 10-3 m/s (2) 3 x 10-6 m/s (3) 3 x 10-9 m/s (4) 3 x 10-12 m/s 12. The wavelength of red light is 7 x 10-7 meter. Express this value in nanometers. 13. If m represents mass in kg, v represents speed in m/s, and r represents radius in m, show that the force F in the formula F = in the unit kg m/s2. mv? can be expressed 14. If PE, represents the potential energy stored in a spring in kg m2/s², and x represents the change in spring length from its equilibrium position in m, what is the unit for the spring constant k in the formula RE

solve 1.31, thanks

Calculate the mass in kilograms of a 2.14 kg object when its velocity, relative to us, is each of the following values. (Notice the progression of these numbers toward the velocity of light, 3.00 × 108 m s-1.) velocity = 2.68 × 108 m s-1 m=______ kg

We sent a probe out to orbit the planet Kerbal at a distance of 5.5x107m from the middle of the planet. It took our probe 3.5x105s to orbit the planet. Calculate the mass of planet Kerbal. Possible Formulas that can be used to answer the question: v=(2πr)/T ac=v2/r ac=(4π2r)/T2 Fc=mac Fg=mg F=(Gm1m2)/d2 g=Gm/r2 T2=(4π2/Gm)r3 v=√(Gm)/r g=9.80m/s2 G=6.67x10-11 (N∙m2)/kg2

One year on Mars is as long as 1.88 years on earth. How many seconds is a Martian year?    Please give the correct answer

The supermassive black hole at the center or our galaxy (Sagittarius A*) has a mass equal to 4.3 million Suns (the mass of the Sun is 1.99 × 1030 kg). The distance from Sgr A* to Earth is 7,940 parsecs, where one parsec is equal to 3.09 × 1016 m. (a) What is the gravitational force that Sgr A* exerts on a 75 kg person on Earth, in units of Newtons? Hint: use Newton's law of universal gravitation. (b) Suppose the same person is sitting 1.0 meter away from a paperclip with a mass of 1.0 grams. What is the gravitational force that the paperclip exerts on the person? (c) Compare the forces from parts (a) and (b). Which is greater?
