Answer:
B . 68.7 N
Explanation:
Given in the question that;
Force = 22 N
Mass = 7.0 kg
Velocity = 4.0 m/s
Gravitational force is the weight of wooden block , calculated as mass times acceleration due to gravity.
F= m* a
F= 7 * 9.81
F= 68.67 N
F= 68.7 N
The solution would be like this for this specific problem:
Given: 5973 K
λ_peak = 2.898 / 5973 K
= 0.00048518 mm = 0.48518 μ = 4851.8 Ậ
Polaris emits peak radiation at 485 nm wavelength.
To add, Polaris, commonly the North Star or Pole
Star, is the brightest star in the constellation of Ursa Minor.
Answer:
Explanation:
Given
Mass of water is
mass of ice is
Latent heat of fusion
The heat capacity of water is
Suppose water is at and it reaches to to melt the ice
the heat released by water must be equivalent to heat absorbed by the ice
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.
All the planets is the answer
