- Could I have help with this physics problemIf S = (1 m) i + (2 m) j + (2 m) k and T = (3 m) i + (4 m) k, the angle between the two vectors a) it's arcades (11/15) b) it cannot be calculated because S and T are not on the same plane. c) is arccos (11/225) d) is arccos (104/225) e) it's arcades (14/15)University students celebrate their graduation with a trip to the sea. One of them decides to go diving and while he is down in the sea, at a not very deep depth, he sees the sun at an angle of 45° above the horizon. What is the true angle of elevation of the sun above the horizon?
- A concave spherical mirror has a radius of curvature of 3.8 m. If a candle that is 6.21 cm high is then placed 2.18 cm in front of the mirror, what is the height of the image formed in cm? Round your answer to 2 decimal places.Consider a mirror lying along the x-axis in R2. A laser starts at the point (−2, 6) and is fired in the direction of ⟨4, −3⟩. The beam travels until it hits the mirror, where it reflects off the mirror and then travels until it hits a wall on the line x = 20. (a) Give a parametrization for the initial path of the laser. (b) At what point does this beam hit the mirror? (c) Give a parametrization for the path of the reflected beam. (d) At what point does this beam hit the wall?A certain statue has a height of 2.5 m. When looked through a lens, the real image that is generated is 2.75 m. What is the magnification of the lens?
