The initial velocity of the sky diver would be t=0. So put that into the equation:
<span>v(0)=64(1−<span>e<span>(−0.19)(0)</span></span>)
and for b it will be
</span><span>(5)=64(1−<span>e<span>(−0.19)(5)</span></span>)</span><span>, and likewise for t=15. You just need to throw it in a calculator.</span>
Answer:
C. Potential energy is related to an object's position, and kinetic
Explanation:
The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
The correct answer is (b.) y/x hertz. That is because the formula to get the frequency is f = v / w. The following values (v=y meters / second; wavelength = x meters) must be substituted to the equation, which leaves you y/x hertz.
Answer: -0.068
Explanation:
A familiar correlation number of R² denotes the degree of correlation between measured data and the curve of best fir
R² = 1 denotes a perfect fit, so that
R = +1, or R = -1 denotes a perfect fit.
R² = 0 denotes no correlation.
To compare the given correlation numbers, we should consider their absolute values. In decreasing order, they are
-0068 => 0.68
0.46 => 0.46
-0.041 => 0.41
0.32 => 0.32
Current is the amount of charged passed divided by elapsed time.
I = Q/Δt
I = current, Q = charge, Δt = elapsed time
We also know an electron has a charge of 1.6×10⁻¹⁹C, so let us find the total charge by multiplying this unit of charge by the total number of electrons:
Q = 1.6×10⁻¹⁹(3×10²⁰) = 48C
We also have Δt = 6s, so let's plug these values in to solve for I:
I = 48/6
I = 8A
