Answer:
20 m/s
Explanation:
In the y direction:
y = y₀ + v₀ᵧ t + ½ gt²
0 m = 45 m + (0 m/s) t + ½ (-9.8 m/s²) t²
t = 3.03 s
In the x direction:
x = x₀ + v₀ₓ t + ½ at²
60 m = 0 m + v (3.03 s) + ½ (0 m/s²) (3.03 s)²
v = 19.8 m/s
Rounded to one sig-fig, the car's velocity was approximately 20 m/s.
Answer:
all chemical reaction involved in early enough energy used to break bonds in reactants and energy released when you want from product
Edith a remake reaction absorb energy and epidemic reaction release energy flow of conversion of energy states that matter cannot be created or destroyed .
Here are the three observable facts that are explained by the nebular theory:
1) Planets all rotate in the same direction
2) Planets all orbit in within 6 degrees of a common plane
3) Planets within the orbit of the Asterioid Belt (terrestrial planets) are rocky while those outside it are gaseous.
Here are the missing statements and its appropriate labels:
all 6 of stars terrestrial planets have a moon as large as earth's moon - NOT CONSISTENT WITH THE THEORY
<span>a star is surrounded by a disk of gas but has no planets - CONSISTENT WITH THE THEORY</span>
<span>a star has 20 planets - CONSISTENT WITH THE THEORY</span>
<span>a stars 5 terrestrial planets orbit in the opposite direction of its 3 jovian planets - NOT CONSISTENT WITH THE THEORY</span>
<span>beyond its jovian planets, a star has two ice-rich objects as large as mars - CONSISTENT WITH THE THEORY</span>
<span>of a stars 5 terrestrial planets, 1 has a moon as large as earth's moon - CONSISTENT WITH THE THEORY</span>
<span>a stars 4 jovian planets formed in its inner solar system and its 4 terrestrial planets formed farther out - NOT CONSISTENT WITH THE THEORY</span>
<span>a star has 9 planets, but none orbit in close to the same plane - NOT CONSISTENT WITH THE THEORY</span>
I would say the most beautiful
Answer:
High-Level Clouds
Cloud types include: cirrus and cirrostratus.
High-level clouds form above 20,000 feet (6,000 meters) and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals. High-level clouds are typically thin and white in appearance, but can appear in a magnificent array of colors when the sun is low on the horizon.
Mid-Level Clouds
Cloud types include: altocumulus, altostratus.
The bases of mid-level clouds typically appear between 6,500 to 20,000 feet (2,000 to 6,000 meters). Because of their lower altitudes, they are composed primarily of water droplets, however, they can also be composed of ice crystals when temperatures are cold enough.
Low-level Clouds
Cloud types include: nimbostratus and stratocumulus.
Low clouds are of mostly composed of water droplets since their bases generally lie below 6,500 feet (2,000 meters). However, when temperatures are cold enough, these clouds may also contain ice particles and snow.
