Answer:
F=mass x acceleration
1000= 2000 x a
a=1000/2000
a=1/2 m/sec^2

#10 when you added the oil to the water they did not mix together. Instead the oil created a layer on the surface of the water. This is because oil is less dense than water and so it floats
Answer:
The correct answer is - 6.49 × 10^3 mm.
Explanation:
The correct scientific notation of the given subtraction problem is:
6.94 × 10^3 mm - 4.5 × 10^2 mm = _____.
The correct number of significant digits is
a. 6.94 × 10^3 mm = 3
b. 4.5 × 10^2 mm = 2
So subtracting the 6.94 × 10^3 mm - 4.5 × 10^2 mm
= 6940 - 450
= 6.49× 10^3 mm.
Answer:
h = 3600 km
Explanation:
Given,
The mass of the Earth, M = 6 x 10²⁴ km
The radius of the Earth, R = 6.4 x 10³ km
The acceleration of the meteor at height, x = 4 m/s²
The acceleration due to gravity at the surface of the Earth is given by the formula,
g = GM/R²
At height 'h' acceleration is given by the formula,
gₓ = GM/Rₓ²
Rₓ² = GM/gₓ
= 6.673 x 10⁻¹¹ X 6 x 10²⁴ / 4
= 1 x 10¹⁴
Rₓ = 1 x 10⁷ m
Where,
Rₓ = R + x
x = Rₓ - R
= 10000 km - 6400 km
= 3600 km
Hence, the height of the meteor where its acceleration due to gravity is 4 m/s² is, h = 3600 km
