Answer:
112 m/s², 79.1°
Explanation:
In the x direction, given:
x₀ = 0 m
x = 19,500 cos 32.0° m
v₀ = 1810 cos 20.0° m/s
t = 9.20 s
Find: a
x = x₀ + v₀ t + ½ at²
19,500 cos 32.0° = 0 + (1810 cos 20.0°) (9.20) + ½ a (9.20)²
a = 21.01 m/s²
In the y direction, given:
y₀ = 0 m
y = 19,500 sin 32.0° m
v₀ = 1810 sin 20.0° m/s
t = 9.20 s
Find: a
y = y₀ + v₀ t + ½ at²
19,500 sin 32.0° = 0 + (1810 sin 20.0°) (9.20) + ½ a (9.20)²
a = 109.6 m/s²
The magnitude of the acceleration is:
a² = ax² + ay²
a² = (21.01)² + (109.6)²
a = 112 m/s²
And the direction is:
θ = atan(ay / ax)
θ = atan(109.6 / 21.01)
θ = 79.1°
That's the familiar description of a comet.
If I were the amateur astronomer who discovered the new comet, then
according to the tradition of the astronomical community, I would have
the privilege of naming it. I would call it Comet AL2006/2016.
Answer:
A. The core makes up the majority of Earth's volume.
Explanation:
Although the core and mantle are about equal in thickness, the core actually forms only 15% of earth's volume whereas the mantle takes up 84%
Because that's called friction. When to things collide it causes friction which makes them stop rolling>
See below.
The following are the guidelines for creating ray diagrams for the generation of an image by a concave mirror:
Rule 1: If the incident ray is parallel to the major axis, the reflected ray will pass through the concave mirror's focus.
The reflected ray is parallel to the principal axis if the incident ray passes through the focus of the concave mirror.
Rule 3: If the incident ray passes through the concave mirror's center of curvature, the reflected ray follows the same path.
Hope this helps!
