On a recent adventure trip, Anita Break went rock-climbing. Anita was able to steadily lift her 800- kg body 20.0 meters in 100
Irina-Kira [14]

Answer:

Anita 's power rating during this portion of the climb is 1568 Watts.

Explanation:

Given that,

Mass of the body, m = 800 kg

Height, h = 20 m

Time, t = 100 s

We need to find the Anita 's power rating during this portion of the climb. Power rating of an object is given by the work done per unit time. It is given by :

P=\dfrac{W}{t}

P=\dfrac{mgh}{t}

P=\dfrac{800\times 9.8\times 20}{100}

P = 1568 Watts

So, Anita 's power rating during this portion of the climb is 1568 Watts. Hence, this is the required solution.

A long, rigid conductor, lying along an x axis, carries a current of 4.99 A in the negative x direction. A magnetic field is pre
Tcecarenko [31]

Answer with Explanation:

We are given that

Current in conductor=I=4.99 A  (-x direction)

Magnetic field=B=3.72\hat{i}+8.72x^2\hat{j}mT=(3.72i+8.72x^2j)\times 10^{-3}

(1mT=10^{-3} T)

x(in m) and B (in mT)

Length of conductor is given in negative x- direction

\vec{L}=-x\hat{i}

dL=-dx\hat{i}

Force on current carrying conductor is given by

F=I(L\times B)

dF=I(dL\times B)

Integrating on both sides then we get

\vec{F}=\int_{1.41}^{2.77}(4.99)(-dx\hat{i}\times (3.72\hat{i}+8.72x^2\hat{j}))\times 10^{-3}

\vec{F}=-\int_{1.41}^{2.77}(4.99\times 10^{-3})\cdot 8.72(x^2\hat{k})dx  (i\times i=0, i\times j=k

\vec{F}=-(4.99\times 10^{-3}\times 8.72)[\frac{x^3\hat{k}}{3}]^{2.77}_{1.41}

\vec{F}=-\frac{(4.99\times 10^{-3}\cdot 8.72)}{3}((2.77)^3-(1.41)^3)\hat{k}

\vec{F}=-0.268 \hat{k} N

a. x- component of force=0

b.y- component of force=0

c.z- component of force=-0.268 N

A _______ is a repeating disturbance or vibration that transfers or moves energy from place to place without transporting mass.
Harman [31]

Answer: wave

Explanation:

These are the basic definitions and characteristic of the terms given, which show tha the only rigth answer is the second option: wave.

1) Force is an interaction. There are four natural forces: electrostatic, gravity, strong nuclear force and weak nuclear force.

2) Wave: is a sequence of pulses or vibrations that cause the continuous transportation of energy (propagation). There is not transport of mass, only energy.

Some examples of waves are sound waves, electromagnetic waves (light, radio waves, micro waves, infrarred waves, ultraviolet waves).

3) Vacuum: is the absence of matter; empty space. Only electromagnetic waves can travel through vacuum; other waves need a medium to travel.

4) Medium: any matter is a medium: a solid, the air, a liquid, all of them are media through which waves can transport its energy, depending of the wavelength.
