Answer:
Explanation:
Of the 4 numbers given, the answer is 1 or A
If you take the absolute value of abs(1 - 1.04) you get 0.04.
(2 - 1.04) = 0.96
1.25 - 1.04 = .21
1.5 - 1.04 = 0.46
The last three are all larger than 0.04
Note: absolute value means the positive difference between 2 numbers (even though it is negative). If it is negative, absolute value makes it positive.
Answer:
20 meters per second
Explanation:
If an object accelerates for 2 seconds, and accelerates by 10 meters per second, then that objects speed will be 20 meters per second, assuming hat there are no other factors involved.
Answer:
The correct answer in which peer forces each act in a different body
Explanation:
Newton's law of action and reaction states that the two forces have equal magnitude, but in the opposite direction, each acting on a body. Which creates acceleration in these, if they act in the same body it would be canceled so there would be no movement.
The correct answer in which peer forces each act in a different body
Force = G · m₁ · m₂ / r²
In all SI units . . .
[ newton ] = [ G ] · [kg] · [kg] / [meter²]
But 'newton' is kg-m / s²
So the formula says
[ kg-m / s² ] = [ G ] · [kg] · [kg] / [meter²]
Divide each side
by kg² : kg-m / s²-kg² = [ G ] / meter²
Multiply each side
by meter² : kg-m-m² / s²-kg² = G
Cancel 'kg' from
top and bottom: m-m² / s²-kg = G
Clean it up: <span> [ G ] = m³ / kg - s² <==
Check:
Look up "Gravitational constant" on-line:
</span>Gravitational constant = 6.67408 × 10-11 m³ kg⁻¹ s⁻² <== yay !<span />
