Answer:
Explanation:
position
y(t) = 2.80t + 0.61t³
velocity is the derivative of position
v(t) = 2.80 + 1.83t²
acceleration is the derivative of velocity
a(t) = 3.66t
F = ma = 5.50(3.66(4.10)) = 82.533 N
which should be rounded to no more than three significant digits and arguably only two due to the 0.61 factor.
F = 82.5 N or 83 N
Yes the units are Newtons, cannot tell what your system will accept. May not want the units at all.
Answer:
Explanation:
Work is the product of force and distance, so the formula is:
The work is 6.00 Joules, but
- 1 Joule (J) is equal to 1 Newton meter (N*m).
- Therefore, the work of 6.00 J is equal to 6.00 N*m
The force is 2.50 Newtons.
The known values are:
Substitute the values into the formula.
We are solving for distance, so we must isolate the variable, d. It is being multiplied by 2.50 Newtons and the inverse of multiplication is division. Divide both sides by 2.50 N.
The units of Newtons cancel out.
The force was applied to the rock over a distance of <u>2.40 meters</u> and choice <u>C</u> is correct.
The correct explanation for the process of formation of dew from the water vapour is The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from gas to liquid.
vapour is a gaseous form, while dew is a liquid state of matter therefore it's clear that vapour has to release energy to come in the liquid state, and in this process vapour, water molecules lose their kinetic and potential energy.
The answer is A ..........
B. False if the speeds are going different directions there speed shall be different
