A wave traveling in a string has a wavelength of 35 cm, an amplitude of 8. 4 cm, and a period of 1. 2 s. What is the speed of th

Drupady [299]

0.29 m/s is the speed of this wave.

How can we determine a wave's speed?

Given: The wave's traveling wavelength is () = 35 cm

The wave's period (t) is 1.2 seconds.

The wave's frequency is 0.833 Hz.

We must ascertain a wave's wave speed.

Formula for wave speed is 35 x 0.833 (wavelength x frequency).

= 29.167 cm/sec

= 0.29 m/sec

As a result, the wave's speed is 0.29 m/s.

A tennis player receives a shot with the ball (0.060 0 kg) traveling horizontally at 56.0 m/s and returns the shot with the ball

Fofino [41]

Explanation:

It is given that,

Mass of the ball, m = 0.06 kg

Initial speed of the ball, u = 56 m/s

Final speed of the ball, v = -34.5 m/s (opposite direction)

(a) Let J is the impulse delivered to the ball by the racquet. It is equal to the change in momentum of the object as :

$J=m(v-u)$

$J=0.06\ kg(-34.5\ m/s-56\ m/s)$

J = -5.43 kg-m/s

(b) The work done by the racquet on thee ball is equal to the change in kinetic energy as :

$W=\dfrac{1}{2}m(v^2-u^2)$

$W=\dfrac{1}{2}\times 0.06((-34.5)^2-(56)^2)$

W = -58.372 Joules

All of the following are examples of nonrenewable resources except __________.

GalinKa [24]

<span>So we want to know which of the following is a renewable source of energy. So oil, natural gas and coal are examples of nonrenewable sources of energy because it takes them a very long time to form. Lumber is considered a form of renewable resource because today we have fast growing trees. </span>

Of the following approximate conversions of celsius into fahrenheit, which is most accurate? a. 24°c almost-equals 75.9°f b. 2°c

Softa [21]

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

<h3>What is Scale of Temperature?</h3>

Scale of temperature is simply a method used in calibrating the physical quantity of temperature in metrology.

Conversion of Celsius into Fahrenheit, Formula is expressed as;

Degree = (0 × 9/5) + 32 = Fahrenheit

First we check each option;

A) 24°c almost-equals 75.9°f

24°C = (24 × 9/5) + 32 = 75.2°F

B) 2°C almost-equals 35.8°f

2°C = (2 × 9/5) + 32 = 35.6°F

C) 34°C almost-equals 92.7°f

34°C = (34 × 9/5) + 32 = 93.2°F

D) 13°c almost-equals 55.0°f

13°C = (13 × 9/5) + 32 = 55.4°F

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

A small boat is moving at a velocity of 1.93 m/s when it is accelerated by a river current perpendicular to the initial directio

olasank [31]

Answer:

16.405m/s

Explanation:

Given, initial velocity = u = 1.93m/s, acceleration = a = 0.750m/s2, time = t = 19.3s, final velocity = v= ?

Using the first equation of linear motion,

v = u + at

v = 1.93 + 0.750 x 19.3

v = 1.93 + 14.475

v = 16.405m/s
