An interstellar ship has a mass of 1.20 × 10 6 kg and is initially at rest relative to a star system. (a) What constant acceleration is needed to bring the ship up to a speed of 0.10 c (where c is the speed of light , 3.0 × 10 8 m/s) relative to the star system in 3.0 days? (b) What is that acceleration in g units? (c) What force is required for the acceleration? (d) If the engines are shut down when 0.10 c is reached (the speed then remains constant), how long does the ship take (start to finish) to journey 5.0 light-months, the distance that light travels in 5.0 months?

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. The answer is .028 T, I just need help understanding how to do it. Please show all steps.
A ray of light from an object you want to look at strikes a mirror so that the light ray makes a 32 degree angle relative to the normal line (a line perpendicular to the surface of the mirror at the point where the ray strikes the mirror). If you want to see the object in the mirror, what angle does your line of sight need to make relative to the normal line? Give your answer as the number of degrees.
Suppose you have a converging lens with a focal length of 65 cm. You hold this lens 120 cm away from a candle. How far behind the lens should you place a notecard if you want to form a clear image of the candle, on the card? Give your answer as the number of centimeters.
