(a) Apply Newton's first law to each of the following situations. In which situations can you conclude that the object is undergoinga net interaction with one or more other objects? (Select all that apply.)A proton in a particle accelerator moves faster and faster.A spacecraft travels at a constant speed toward a distant star.A car travels at constant speed around a circular race track.A hydrogen atom remains at rest in outer space.O A book slides across the table and comes to a stop. Part 2(b) A spaceship far from all other objects uses its impulse power system to attain a speed of 104 m/s. The crew then shuts off thepower. According to Newton's first law, what will happen to the motion of the spaceship from then on? (Select all that apply.)The spaceship will enter a circular orbit.The spaceship will travel on a curving path.The spaceship will gradually slow down.The spaceship will move in a straight line.The speed of the spaceship will not change.O The spaceship will stop suddenly.

QUESTION 4 It is year 2321, and humans colonized Mars. You are in an elevator on a Martian skyscaper and you are standing on a bathroom scale of mass 1.1 kg. Your mass is 74.3 kg. The mass of the elevator car is given as 1,175 kg. While the elevator is moving you notice that the bathroom scale shows your weight as 325.2 Newtons. What should be accelaration of the elevator at the moment you read your weight? Enter your answer by taking the upward direction as the positive direction in units of m/s. (accelaration due to gravity magnitude on Mars surface is 3.75 m/s2)
1. You and a friend set up an umbrella and chairs at Torrey Pines State Beach. Your friend goes boogie boarding while you read a book. Half an hour later you are surprised to see that your friend has moved south, parallel to the beach. They are still boogie boarding the same distance from shore, in the surf zone. Why did your friend drift parallel to the beach? 2. The Sun is much more massive than the Moon, but the Moon has a bigger influence on Earth's tides than the Sun. Why is this? 3. Even when there is no wind at the beach, we still see waves. What is the source of these waves? Do not include tides, mass movement, or earthquakes in your answer. 4. What causes ocean surface water to sink to the bottom and become deep water? Where does this happen? 5. How do you escape a Rip Current?

An astronaut is doing a spacewalk on a long tether at 0.1 km away from the International Space Station (mass of 420,000 kg). His spacesuit includes a very sensitive gravitometer, which indicates the gravitational force acting on the astronaut and his spacesuit from the ISS is 7.0 E−7 N. What is the mass of the astronaut in his suit if G = 6.67 E−11 N*m2/kg2? 1. 150 kg 2. 200 kg 3. 250 kg 4. 300 kg
With density Y1(unit: kg/m), 3 endless wires are just above the x,y,z axes. Find the gravitational field at (x,y,z) position. NOTE: Give your answer in terms of (x,y,z, ^x, ^y, ^z(unit vectors), G, Y1) A hint is given in the figure.
Imagine that two identical containers, one filled with marbles and the other filled with Styrofoam beads, are released simultaneously from rest from the same height-s Earth's surface. (a) Which container, if either, experiences the greater gravitational force? O the container filled with marbles O the container filled with beads O Both containers will experience the same gravitational force. Justify your answer. O Since both containers fall to the ground with the same acceleration, both will experience the same gravitational force. O Gravitational force is directly proportional to mass, so the heavier container would experience the greater gravitational force. O Gravitational force is inversely proportional to mass, so the lighter container would experience the greater gravitational force. O Since the acceleration due to gravity is 9.8 m/s² for each container, both will experience the same gravitational force. (b) which container, if either, experiences the greater acceleration from…
Gravitational forces are different from electrostatic forces because gravitational forces are: O Repulsive, only O Attractive, only O Neither attractive nor repulsive Both attractive and repulsive
A flea jumps by exerting a force of 1.19 ✕ 10−5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.700 ✕ 10−6 N on the flea. Find the direction and magnitude of the acceleration of the flea if its mass is 6.40 ✕ 10−7 kg. Do not neglect the gravitational force. (Assume that the breeze blows in the +x-direction and that the +y-direction is up.) Magnitude= ? Direction (counterclockwise from x axis)= ?
