A sphere is charged with electrons to −9 × 10−6 C. The value given is the total charge of all the electrons present in the sphere. To calculate the number of electrons in the sphere, we divide the the total charge with the charge of one electron.

N = 9 × 10−6 C / 1.6 × 10−19 C
N = 5.6 x 10^13

The motor of a four wheeler traveling along a muddy trail generates an average power of 7.05 104 W when moving at a constant spe

Gennadij [26K]

Answer:

$F=733.33 N$

Explanation:

Power is the work to make a motion in a determine time also the al the work is the force make in a distance so:

$P=\frac{W}{t}$

$W=F*d$

Replacing

$P=F*\frac{d}{t}$

Knowing that the velocity is:

$v=\frac{d}{t}$

So:

$P=F*v$

Solve to F to determinate the tension that in this case is the force in the rope

$F=\frac{P}{v}$

The power is the total power so:

$P=8.15x10^4W-7.05x10^4W=11x10^3W$

$F=\frac{3kW}{15\frac{m}{s}}=733.33 N$

For this exercise, use the position function s(t) = −4.9t2 + 250, which gives the height (in meters) of an object that has falle

Answer:

t=7.14s

v=-69.972 m/s

Explanation:

Position function

$s(t)=-4.9*t^{2}+250$

Velocity is the derivative of position function

$V(t)=\frac{dx}{dt}\\V(t)=-2*4.9*t\\V(t)=-9.8*t$

The time the object hit the ground can be find by the given function know that the position is going to be 0m

$s(t)=-4.9*t^{2}+250$

$s(t)=0\\0=-4.9*t^{2} +250\\t=\sqrt{\frac{250}{4.9}}\\t=7.14s$

Check:

$s(7.14)=-4.9*(7.14s)^{2}+250\\ s(7.14)=-250+250\\s(7.14)=0m$

So the velocity can be find using the time discovery before and using the same function but with the derivate

$V(t)=-2*4.9*t\\V(7.14)=-2*4.9*(7.14)\\V(7.14)=-69.972 \frac{m}{s}$

The velocity is negative because the object is moving downward
