The reason is that in case of motion of macroscopic objects, we are not concerned with the thermodynamiccal parametres but only the mechanical parametres. Therefore, change in energy here means the change in Mechanical energy which is the sum of kinetic and potential energy. There is no role of temperature in this context hence no heat, work or internal energy involved.

An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...
A satellite of mass 210 kg is placed into Earth orbit at a height of 400 km above the surface. (a) Assuming a circular orbit, how long does the satellite take to complete one orbit? 1.54 (b) What is the satellite's speed? 7676 m/s (c) Starting from the satellite on the Earth's surface, what is the minimum energy input necessary to place this satellite in orbit? Ignore alr resistance but include the effect of the planet's daily rotation. The satellite...
A satellite of mass 180 kg is placed into Earth orbit at a height of 750 km above the surface. (a) Assuming a circular orbit, how long does the satellite take to complete one orbit? h (b) What is the satellite's speed? m/s (c) Starting from the satellite on the Earth's surface, what is the minimum energy input necessary to place this satellite in orbit? Ignore air resistance but include the effect of the planet's daily rotation.
A satellite of mass m 400 kg is observed with the initial speed v 3 km/s at the initial altitude h 4000 km above the Earth's surface. The satelite descends in a free fall and hits the ocean with the final speed w. Which one of the followings statements is the correct form of the 프~ Problem 6(3 point ed push of what energy conservation in this process? these equations M stands for the mass of the Earth, and R...
Please use the formulate sheet and show all steps to make sure
the question is worth any points
a) The initial ratio of deuterium (D) to hydrogen (H) in a planet's atmosphere was 175000; however, the present ratio is 1/1500 and the initial and final abundances of D are 5 x 10° atoms per m3 and 9 x 106 atoms per m2, respectively. What fraction of deuterium has been lost, and what fraction of hydrogen has been lost in this...
PLEASE ONLY DO D IN MATLAB. I DID A B AND C, dont need
them.
Intro to Computers for Engineers Recitation 11 In today's class, we are modeling a spacecraft. Please submit all functions you write. Pay very careful attention to names. If you name a function differently from what you are instructed, things might not work. Test your code using the scripts siml.m and sim2.m before trying to submit on zyLabs. A. [Submit on zyLabs] Write a function that...
