Which of the outer planets is MOST like Earth? How?
Over [174]

Answer:

It is not impossible to answer the question, my apologies for “discrediting” the answer it would have to be Venus, the outer planet most similar to earth.

Explanation:

Venus is very similar to earth, as many studies, research, factual intellectual based concepts - the size, shape, surface gravity, average density, mass, average days of 24 hours, season changes similar to earth, and tilted axis. As well as similar climate make Venus the most accurate answer.

Hope this helps! Thank you for your time.

What is the frequency of light for which the wavelength is 7.1 × 102 nm?
Brilliant_brown [7]

Answer:

Frequency, f=4.22\times 10^{14}\ Hz

Explanation:

Given that,

Wavelength of the light,

\lambda=7.1\times 10^2\ nm=7.1\times 10^2\times 10^{-9}\ m\\\\\lambda=7.1\times 10^{-7}\ m

We need to find the frequency of light. We know that light is an electromagnetic wave. It moves with the speed of light. So,

c=f\lambda

f is the frequency of light

f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8\ m/s}{7.1\times 10^{-7}\ m}\\\\f=4.22\times 10^{14}\ Hz

So, the frequency of light is 4.22\times 10^{14}\ Hz. Hence, this is the required solution.

A piano string having a mass per unit length equal to 5.00× 10⁻³kg / m is under a tension of 1350N . Find the speed with which a
DiKsa [7]

Based on the mass per unit length and the tension, the speed that the wave travels on this string is 519.615 m/s.

<h3>What is the speed?</h3><h3 />

The speed that the wave travels can be found as:

Velocity² = Tension / Mass per length

Solving gives:

Velocity² = 1,350 / 0.005

Velocity² = 270,000

Velocity = √270,000

= 519.615 m/s

The distance covered by a car at a time, t is given by x = 20t + 6t4, calculate
Anni [7]

Answer:

(i) v = 44 m/s

(ii) a = 72 m/s^2

Explanation:

You have the following equation for the potion of a car:

x=20t+6t^4

(i) The instantaneous velocity is the derivative of x in time:

\frac{dx}{dt}=20+(6)(4)t^3=20+24t^3

for t = 1 is:

v(t=1)=\frac{dx}{dt}=20+24(1)^3=44m/s

(ii) The instantaneous acceleration is the derivative of the velocity:

\frac{dv}{dt}=24(3)t^2=72t^2

for t = 1

a(t=1)=\frac{dv}{dt}=72(1)^2=72m/s^2
