Answer:
Length of hole (s) = 362.77 m (Approx)
Explanation:
Given:
Time taken to hit the bottom (t) = 8.6 s
Acceleration due to gravity (g) = 9.81 m/s²
Find:
Length of hole (s) = ?
Computation:
Initial velocity (u) = 0 m/s
S = ut +1/2(gt²)
S = (0)(8.6) +1/2(9.81)(8.6)(8.6)
S = 1/2(9.81)(8.6)(8.6)
S = 1/2(9.81)(8.6)(8.6)
S = 362.7738
Length of hole (s) = 362.77 m (Approx)
When light changes the medium it travels through it also changes speed. The speed in medium is given by formula:
Rearranging formual gives:
From this formula we can make conclusion that index of refraction is inversely proportional to speed of light in medium. This means that greater speed gives smaller index of refraction.
Answer:
<h2>1.5 ohms</h2>
Explanation:
Power is expressed as P = V²/R
R = resistance
V = supplied voltage
Given P = 600W and V = 30V
R = V²/P
R = 30²/600
R = 900/600
R = 1.5ohms
magnitude of its resistance is 1.5ohms
Answer:Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across. The total mass of all the asteroids combined is less than that of Earth's Moon.❤
Answer:
45.1/3× 3.1/2 + 50.1/2× 2.1/2
=136/3. 7/2.+ 101/2× 5/2
=952/6 + 505/2
=( 952+ 1515)/6
=411.16
