At what distance from Planet X (mass = mX) will an astronaut on the way to...
Part A Astronaut Spud Nick is space-travelling from planet X to planet Y at a speed of 0.84c. When he is precisely halfway between the planets, a distance of 1 light-hour from each in the planets' frame, nuclear devices are detonated. The explosions are simultaneous in the frame of the planets. What is the difference in time of arrival of the flashes from the explosions as observed by Spud? Astronaut Spud Nick is space-travelling from planet X to planet Y...
Q14. A planet of mass m is a distance d from Earth. Another planet of mass 2m is a distance d from Earth. Which force vector best represents the direction of the total gravitation force on Earth? A) B) C) D) E) d) c) al b)
An astronaut weighs 850 N on the Earth’s surface. When the astronaut lands on Planet X, she weighs 190 N. To the nearest tenth of a m/s2, what is the acceleration of gravity on Planet X? (hint: first find her mass!) An elevator car loaded with two passengers has a mass of 1200 kg. What tension must be applied by the elevator cable to give the car an acceleration of 1 m/s2 upward? Round your answer to the nearest newton....
A planet of mass 5 x 1024 kg is at location <5 x 1011, -4 x 1011, 0> m. A star of mass 9 x 1030 kg is at location <-6 x 1011, 9 1011, 0> m. It will be useful to draw a diagram of the situation, including the relevant vectors. (a) What is the relative position vector pointing from the planet to the star? (b) What is the distance between the planet and the star? (c) what is...
Planet X of mass mx = 6.3 × 1024 kg orbits S in uniform circular motion at a distance rx and with a period Px = 1.5 years (=4.7304 × 107 s). The mass of the star S is MS = 2 × 1031 kg and its radius is RS = 4.2 × 108 m, as shown in the figure. 1) What is rx, the orbital radius of Planet X around the Sun? a) rx = 4.21 × 109 m...
Problem 3.13 A planet of mass 3 x 104 kg is at location <6 x 101, s 101, 0 m. A star of mass 9 x 100 kg is at location <3 x 1011 8 x 10, 0> m. wil be useful to draw a diagram of the situation, including the relevant vectors (a) What is the relative position vector 7 pointing from the planet to the star? (b) What is the distance between the planet and the star? 1기...
Two perfectly matched athletes on level ground are pulling opposite ends of a rope in a tug of war. Each athlete can pull with a force of 200 pounds. The rope is not accelerating because to have the required strength the mass of the rope is very large each athlete is only able to apply a tiny force on the rope the athletes apply equal and opposite forces on the rope and the net force on the rope is zero
Put two point charges on the same x (or y) axis, some distance apart, but fixed in place (immovable). One is positive, the other is negative, but their magnitudes are unequal. No other charges are nearby these two. There are two positions the same x (or y) axis where the net electric potential due to these two charges is zero. The question below can be answered for either position, but doesn't have to be answered for both. Question: choose one...
A planet of mass 7 X 1024 kg is at location <4 x 10", -8 x 10'1,0>m. A star of mass 2 x 100 kg is at location <.4 x 10 ,8 x 10 ,0> m. It will be useful to draw a diagram of the situation, including the relevant vectors. *Part 1 Your answer is correct. (a) What is the relative position vector 7 pointing from the planet to the star? 7 -8E1116E11 > Answer 1: the tolerance is...
A dwarf planet with an average orbital distance of 4.14 x 10° kilometers is kept in its orbit by 6.94 x 101 Newton force exerted on it by the Sun. MSun = 1.99 x 1030 kg. MFarth 5.97 x 1024 kg. What is the mass of that planet? kilograms (use scientific notation and round the coefficient to two decimals). A. В. How many Earth masses is that equivalent to? (use scientific notation and round the coefficient to two decimals). An...
