Answer:
no idea thanks you veryuch
Answer:
The answer is 200N.
Explanation:
Force=MA
m=mass
a=acceleration
Let's plug in our numbers into the equation:
20x10 = 200
Since force is measured in newtons, the answer is 200 newtons. (N)
Answer:A game of knock it down.
Explanation:
Volume = mass / density
Volume = 20 / 7.87
Volume = 2.54 (2 s.f)
Answer:
a) 3.0×10⁸ m
b) 0 m
Explanation:
Displacement is the distance from the starting position to the final position.
a) In half a year, the Earth travels from one point on the circle to the point on the exact opposite side of the circle (from 0° to 180°). The distance between the points is the diameter of the circle.
x = 2r
x = 2 (1.5×10⁸ m)
x = 3.0×10⁸ m
b) In a full year, the Earth travels one full revolution, so it ends up back where it started. The displacement is therefore 0 m.
