From the calculation, the speed of sound at 10 K is 63.5 m/s.

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

We know that the speed of sound is directly proportional to the temperature of the body thus we can write;

V1/V2 = √T1/T2

Then;

T1 = 0 degrees or 273 K

T2 = 10 K

V1 = 330 m/s

V2 = ?

330/T2 = √273/10

330/T2 = 5.2

330 = 5.2T2

V2 = 330/5.2

V2 = 63.5 m/s

One end of a string is fixed. An object attached to the other end moves on a horizontal plane with uniform circular motion of ra
sveticcg [70]

Answer:

If both the radius and frequency are doubled, then the tension is increased 8 times.

Explanation:

The radial acceleration (a_{r}), measured in meters per square second, experimented by the moving end of the string is determined by the following kinematic formula:

a_{r} = 4\pi^{2}\cdot f^{2}\cdot R (1)

Where:

f - Frequency, measured in hertz.

R - Radius of rotation, measured in meters.

From Second Newton's Law, the centripetal acceleration is due to the existence of tension (T), measured in newtons, through the string, then we derive the following model:

\Sigma F = T = m\cdot a_{r} (2)

Where m is the mass of the object, measured in kilograms.

By applying (1) in (2), we have the following formula:

T = 4\pi^{2}\cdot m\cdot f^{2}\cdot R (3)

From where we conclude that tension is directly proportional to the radius and the square of frequency. Then, if radius and frequency are doubled, then the ratio between tensions is:

\frac{T_{2}}{T_{1}} = \left(\frac{f_{2}}{f_{1}} \right)^{2}\cdot \left(\frac{R_{2}}{R_{1}} \right) (4)

\frac{T_{2}}{T_{1}} = 4\cdot 2

\frac{T_{2}}{T_{1}} = 8

If both the radius and frequency are doubled, then the tension is increased 8 times.

A small first-aid kit is dropped by a rock climber who is descending steadily at 1.9 m/s. After 2.4 s, what is the velocity of t
Genrish500 [490]

Answer:

v=-21.65 m/s

Explanation:

From the exercise we have:

v_{o}=1.9m/s\\ g=9.81 m/s^{2}\\ t=2.4s

To find the velocity after 2.4s we need to use the following formula:

v=v_{o}+gt

v=1.9m/s-(9.81m/s^{2})(2.4s)=-21.65m/s

The negative sign means that the kit is going down.

What does the positive sign tell you about any vector<br> quantity ?
vredina [299]

Answer:

With a vector, however, the sign simply tells you about the direction of the vector. If you're travelling with a velocity of 20 km/hr east, it means you're travelling east, and your speed is 20 km/hr.
