<em>Asteroids, often known as minor planets, are stony, airless leftovers of our solar system's early development about 4.6 billion years ago.</em>
<em>The majority of this ancient space junk may be found in the main asteroid belt, orbiting the Sun between Mars and Jupiter. Asteroids range in size from Vesta, the largest at 329 miles (530 kilometers) in diameter, to asteroids as small as 33 feet (10 meters). The cumulative mass of all asteroids is less than that of the Earth's Moon.</em>
Hi! the atom in this particular problem has emitted an alpha particle in a nuclear reaction.
Glad I could help, and happy learning!
Answer:
The height from which the ball was thrown is 18.82 m
Explanation:
Given;
horizontal velocity of the ball, vi = 27.0 m/s
horizontal distance of the ball, d = 53.0 m
Apply kinematic equation, to determine the time taken for the ball to make a horizontal distance of 53.0 m.
d = vt
t = d/v
t = 53/27
t = 1.96 seconds
This time is equal to the time the ball spent in air before hitting the ground.
The vertical distance at this time, is the height from which the ball was thrown, and it is calculated as;
h = vt + ¹/₂gt²
v is vertical velocity, = 0
g is acceleration due to gravity
h = ¹/₂ x 9.8 x (1.96)²
h = 18.82 m
Therefore, the height from which the ball was thrown is 18.82 m
Answer:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
