Answer:

The guitarist should increase the tension of the string.

Explanation:

The frequency of a vibrating string is determined by fn=(n/(2L))√T/μ. So if the tension in the string increased, the rate at which it vibrates (the frequency) will also increase.

Therefore it is advisable that she increase the tension of the string.

I hope it helps, please give brainliest if it does

Air conditioners sold in the United States are given a seasonal energy-efficiency ratio (SEER) rating that consumers can use to
amid [387]

Answer:

112.58

Explanation:

The Coefficient of Performance of any system is denoted by COP=Q/W, where Q is the useful heat supplied or removed and W is the work required by the system. According to the first law of thermoddynamics Qh= Qc + W, where Qh is the heat transfered to the hot reservoir and Qc is the heat collected from the cold reservoir. Substituting the values for W and apllying the limitation for maximum theoretical efficiency we end up with the eqution shown below.

The Coefficient of Performance of air conditioner or COP is denoted by

COP(cool) = Tc/(Th- Tc)

where Tc: the lowest temperature

           Th: the highest temperature

converting the values to Kelvin and adding them in the above equation

COP(cool) = (25+273)/((34+273)-(25+273))

                 = 298/(307-298)

                 = 298/9 = 33.11

From the question, it is stated that COP=SEER/3.4

hence, SEER= COP * 3.4

SEER= 33.11 * 3.4 = 112.58

A girl travels along the circumference of a circle of radius 14 m. What is her total distance travelled and displacement when sh
AysviL [449]

Answer:

87.976meters, 43.988 meters, 65.982 meters

Explanation:

Given data

Radius= 14m

Let us find the circumference of the circle

This is equivalent to the total distance covered

C= 2πr

C= 2*3.142*14

C= 87.976 meters

Hence the total distance is

87.976meters

The displacement when she has covered 1/2 the circle is

=87.976/2

=43.988 meters

The displacement when she has covered 3/4 the circle is

=87.976* 3/4

=65.982 meters

Please help ASAP. There are 3 questions an answer to any one of them would be appreciated.
Andrei [34K]

Answer:

<u><em>a = 10 is the answer</em></u>

<em><u>m = 2.5 is the answer to the second question</u></em>

<em><u></u></em>

Explanation:

1. a = f/m

a = acceleration = ?

f = force = 36 N

m = mass = 3.6

a = 36/3.6

a = ?

<u><em>a = 10 is the answer.</em></u>

2. m = f/a

m = mass

f = force

a = acceleration

f = 15N

a = 6.0

m = ?

m = 15/6

<em><u>m = 2.5 is the answer to the second question.</u></em>
