Answer:
Workdone = 2906.25J
Explanation:
Given the following data;
Force, F = 155
Distance, d = 0.75
Stroke, s = 25
Mathematically, work done is given by the formula;
Work done = force * distance * stroke
Where,
W is the work done
F represents the force acting on a body.
d represents the distance covered by the body.
s is the number of strokes.
Substituting into the equation, we have;
Workdone = 2906.25J
1. Earth's moon has no atmosphere because the moon's gravity is too weak to hold onto gas molecules.
2. On the moon, maria are low flat plains. The word maria comes from the Latin word mare, which means sea.
Answer:
D. Plane of orbital rotation
Explanation:
The orbital plane of an object orbiting around another is the geometric plane that contains the orbit in question.
By definition, the inclination of a planet in the solar system is the angle between the orbital plane of the solar system and the orbital plane of the Earth.
Answer:
The molecular formula for the compound is C4H8.
Explanation:
Emperical formula is CH2
Molar mass = 56 g/mol
Molar mass = (CH2)n
56 = (12 + 1×2)n
56 = (12 + 2)n
14n = 56
n = 56/14 = 4
Molecular formula = (CH2)n = (CH2)4 = C4H8
