The sine of an angle is (opposite side) / (hypotenuse) .
Multiply each side by (hypotenuse, and you have
Opposite side = (hypotenuse) x (sine of the angle) .
Sin(12°) = 0.2079...
Opposite side = (52 m) x (0.2079)
= 10.81 meters .
Answer:
mass
Explanation:
astronomers use Newtons gravitational law as a link between gravity and orbits to measure the masses of stars and planets.
Newtons gravitational law states that the gravitational force of attraction between two planets is proportional to their masses and inversely proportional to the square of the distance between them.
Answer:
The excited electron itself can be passed to another molecule
Explanation:
The difference in the speeds of the two types of waves
is (8.9 - 5.1) = 3.8 km/sec.
In 73 sec, the faster one pulls ahead of the slower one
by (73 x 3.8) = <em>277.4 km</em>.
n a plate glass factory, sheets of glass move along a conveyor belt at a speed of 15.3 cm/s. An automatic cutting tool descends at preset intervals to cut the glass to size. Since the assembly belt must keep moving at constant speed, the cutter is set to cut at an angle to compensate for the motion of the glass. The glass is 73.4 cm wide and the cutter moves from one edge to the other in 3.0 s. At what angle to the width of the sheet should the cutter be set to move
