______ is the total distance traveled divided by the total time of travel.

A graph of angular position v. time has the following equation:

Harman [31]

Answer:

you can simply answer by derivative = 3.5x^2+25x+250-y=0 you can derivate this eqn 7x +25-1=0 7x=24 yo u can divide you get it

An 86.0-kg climber is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves li

Brrunno [24]

Answer:

x = 1.95 m

Explanation:

As we know that total mechanical energy is conserved here

So gravitational potential energy of the climber will convert into spring potential energy

So we will have

$mg(L + x) = \frac{1}{2}kx^2$

here we know that

m = 86 kg

L = 0.750 m

$k = 1.20 \times 10^3 N/m$

now we will have

$86\times 9.8(0.750 + x) = \frac{1}{2}(1.20 \times 10^3) x^2$

$0.750 + x = 0.71 x^2$

$x = 1.95 m$

The magnetic field in a plane monochromatic electromagnetic wave with wavelength λ = 598 nm, propagating in a vacuum in the z-di

Oksanka [162]

Answer:

For this given plane monochromatic electromagnetic wave with wavelength λ=598 nm, the wavenumber is $k=0,0105\ x\ 10^{-9}\ m^{-1}$ .

Explanation:

For a plane electromagnetic wave we have that the electrical and magnetic field are:

$E(r,t)=E_{0}\ cos ( wt-kr)\\\ B(r,t)=B_{0}\ cos(wt-kr)$

In this case we have the data for the magnetic field. We are told that the magnetic field in a plane electromagnetic wave with wavelength λ=598 nm, propagating in a vacuum in the z direction ( $\hat k$ ) is described by
