51mm = 5.1e-5km
0.00005100000km
the answer is true acceleration is the change in distance over time.
hope this helps
Answer: As you already know people have cloned dolly sheep but what about people? will we be able to clone ourselves one day?. Good question, actually scientist believe it may be possible years from now, though it wouldn't be right if we didn't research. It is hard to clone animals let alone people which is probably one of the reason's some human's oppose it so much. Think of it this way though if we cloned ourselves or someone clones us after we die it'll be like we never left. It will bring less heart-ship to people knowing can always have that person. it will also make life more evolved in evolution and theory.
i couldn't think of anything else but her's a start :)
Answer:
x rays is the correct answer
Answer:
(A) 3.92 m/s²
Explanation:
From friction,
F = μR .................. Equation 1
Where F = Frictional force, μ = coefficient of static friction, R = Normal reaction.
But,
R = mg and
F = ma
therefore
ma = mgμ
Where a = acceleration, g = acceleration due to gravity, m = mass of the crate.
a = gμ...................... Equation 2
Given: μ = 0.4
Constant: g = 9.8 m/s
Substitute into equation 2
a = 0.4(9.8)
a = 3.92 m/s²
Hence the right option is (A) 3.92 m/s²
