Answer: 217.52 N
Explanation: The applied force is 20 N, the distance covered is 12.0 m and the angle is 25° above the horizontal.
Hence the formulae that defines work done is given by
W = Force × distance
But since the force has been inclined at an angle θ above the horizontal, the horizontal component of force is neccesary to produce the required motion to make the child do work on the wagon.
Hence
Work done = (horizontal component of force) × distance
Work done = F cos θ × distance
Work done = 20 cos 25 × 12 = 217.52 N
Answer:
It will end composed of carbon and oxygen, with the lighter (outer) hydrogen and helium layers blown off.
Explanation:
I believe you are incorrect. A weathered mountain would appear more jagged.
I do believe with a lot of exposure to weather will make the mountain appear somewhat more jagged compared to a mountain that is less weathered.

The answer to this problem is C table salt. This is because a pure substance is defined as substances that are made up of only one type of atom or molecule. in this case, salt. You cannot divide this further than what it is without any further effort.
The five planets that you can see from Earth without a telescope are Mercury, Venus, Mars, Jupiter and Saturn.
