Answer:
tan 249 = 2.61
tan 249 = tan (249 - 180) = tan 69 = 2.61

Answer:
Explanation:
Step one:
Given data
work-done in dragging the trash= 236J
applied force= 18.9N
distance moved= 24.4m
Required
The angle of the applied force
Step two:
We know that work done is
WD= F * distance
<em>The work is the product of the horizontal component of the force and the distance.
</em>
Horizontal force = 236 ÷ 24.4
= 9.67 N
Cos θ = Horizontal force ÷ Actual force
Cos θ = (236 ÷ 24.4) ÷ 18.9 = 236 ÷ 461.16
The angle is approximately 59˚
The common method would be to use Balance, If you think about it, on other planets, the balance weights change by the same factor as the object you are measuring. Your mass measured with a balance would be the same on the moon as it is on Earth. Weight is a measuring of gravity's effect on something. Mass is another story, it's the amount of matter in an object. Move to another planet and its object's weight will change, however, its mass will remain the same.
Answer:
The heat doesn't come from any of those the heat comes from the Sun
Explanation:
But the thing that holds the heat from the Sun is the Earth's atmosphere.
When he gets hot the carbon dioxide holds in the heat but when the when oxygen it meets the heat in the air it makes it become cooler
