Answer:

0.87 m

70.6 Hz

Explanation:

L = length of the rope = 1.30 m

n = order of the harmonic = 3

\lambda = Wavelength

Wavelength is given as

\lambda = \frac{2L}{n}

\lambda = \frac{2(1.30)}{3}

\lambda = 0.87 m

v = Speed of transverse wave = 61.4 m/s

f = frequency of the third harmonic

frequency is given as

f = \frac{v}{\lambda }

f = \frac{61.4}{0.87}

f = 70.6 Hz

Marisa’s car accelerates at an average rate of 2.6m/s^2. Calculate how long it takes her car to accelerate from 24.6m/s to 26.8m
djverab [1.8K]

given info is... Acceleration(a)=2.6m/s^2

                       final velocity(v)=26.8m/s

                       initial velocity(u)=24.6m/s

need to find.... time(t)=?

a=\frac{v-u}{t} \\2.6=\frac{26.8-24.6}{t} \\\\

t=\frac{v-u}{a}

t=\frac{26.8-24.6}{2.6}

t=0.846s

What is the basic difference between ultraviolet, visible, and infrared radiation?
N76 [4]
To me the basic difference is their frequency and wavelength.

For frequency :
Infrared < visible light < ultraviolet

For wavelength :
Infrared > visible light > ultraviolet

Newton’s laws of motion are an inherent part of our everyday life. Starting from the beginning of the day till the end, Newton’s
12345 [234]

1st

Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: Law 1. A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.

2nd

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

3rd

His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.

hope this helps u :)
