Concept explainers
The Moon barely covers the Sun during a solar eclipse. Given that Moon and Sun are. respectively. 4 × 105 km and 1.5 × 108 km from Earth, determine how much bigger the Sun’s diameter is than the Moon’s. If the Moon’s radius is 1800 km, how big is the Sun?

- A possible explanation of observations is called a(n) ___. (1.2)arrow_forwardA person is standing at the edge of the water and looking out at the ocean (see figure). The height of the person's eyes above the water is h = 1.5 m, and the radius of the Earth is R = 6.38 x 106 m. (a) How far is it to the horizon? In other words, what is the distance d from the person's eyes to the horizon? (Note: At the horizon the angle between the line of sight and the radius of the earth is 90°.) (b) Express this distance in miles.arrow_forwardGiven P(-30, -42, 47) in rectangular coordinate system, what is Φ (phi) in cylindrical coordinates of P in degrees? (Compute up to 4 decimal places)arrow_forward
- What is the area of a circle of radius (a) 11.37 m and (b) 6.8 m?arrow_forwardcan you help me to solve this? and kindly put the answers as whole number or decimals and not the significant figures? Thank you!arrow_forwardA certain corner of a room is selected as the origin of a rectangular coordinate system. If a fly is crawling on an adjacent wall at a point having coordinates (3.8, 0.5), where the units are meters, what is the distance of the fly from the corner of the room in meters?arrow_forward
- You are driving into St. Louis, Missouri, and in the distance you see the famous Gateway-to-the-West arch. This monument rises to a height of 192 m. You estimate your line of sight with the top of the arch to be 1.61 ° above the horizontal. Approximately how far (in kilometers) are you from the base of the arch? Number Type your answer here Units Choose your answer herearrow_forwardcalculate the following and express the answer in the proper number of significant figures: (3.245x0.035x9.0023)/(4.076x2.01x42.3)arrow_forwardA student wanted to calculate the radius, r, of the base of a spherical cylinder. The student measured both the volume of the cylinder and its height and obtained the following: Volume, V = (92± 1) cm^3 . Height, h = (11.5 ± 0.1) cm. V = π * (r^2) * h. Calculate the radius of the base of the cylinder.arrow_forward

If a fly is crawling on an adjacent wall at a point having coordinates (2.5, 1.9), where the units are meters, what is the distance of the fly from the corner of the room?arrow_forwardWhat is 47.905 rounded to three significant figures? I put 48.0 and it was incorrect.arrow_forwardAn airplane flies 200 km due west from city A to city B and then 360 km in the direction of 30.5° north of west from city B to city C. (a) In straight-line distance, how far is city C from city A? km (b) Relative to city A, in what direction is city C? ° north of west (c) Why is the answer only approximately correct?arrow_forward
