How many seconds will it take an echo to reach your ears if you yell toward a mountain

DiKsa [7]

It will take 0.556 seconds for an echo to reach one's ears

<h3>Calculating the time to hear an echo</h3>

From the question, we are to determine how long it would take an echo to reach one's ears

From the formula,

$Speed = \frac{2 \times distance \ travelled\ by \ sound}{Time}$

NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance

From the given information,

Distance = 92.0 m

NOTE: Speed of sound in air at 0 °C ≅ 331 m/s

Putting the parameters into the formula, we get

$331 = \frac{2 \times 92.0}{Time}$

$Time = \frac{2 \times 92.0}{331}$

Time = 0.556 secs

Hence, it will take 0.556 seconds for an echo to reach one's ears.

charle [14.2K]

Answer:

$5,612.16

Step-by-step explanation:

Part 1) Account I earns 4% annual simple interest.

we know that

The simple interest formula is equal to

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

substitute in the formula above

Part 2) Account II earns 4% interest compounded annually.

we know that

The compound interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

t=3 years

p=$2,500

r=4%=4/100=0.04

substitute in the formula above

A=2,500(1+0.04 * 3)

A=2,500 (1.12)

A=$2,800

Part 3) What is the sum of the balances of Account I and Account II at the end of 3 years?

Sum the two final investment

$2,800 + $2,812.16 = $5.612.16
