how do you know which magnitude is higher or how do you compare them?

Answers

Answer 1
Magnitudes are measured by intensity so a 3.4 earthquake is much less stronger than a 4.5 earthquake it’s very literally when measuring them the higher the number the stronger it is

Sometimes hikers carry radio beacons so that search and rescue teams can find them in case of emergency. Some of these beacons transmit radio waves with a frequency of 300,000 Hz. (300kHz) What is the wavelength of these waves?

Answers

Answer:

1000 m

Explanation:

Given that,

The frequency of radio waves f = 300,000 Hz

We need to find the wavelength of these waves.

The formula to find wavelength is as follows :

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{300000}\\\\\lambda=1000\ m[/tex]

So, the wavelength of these waves is 1000 m.

What is the wavelength of a wave that is traveling at 343 m/s with a frequency of 1000 Hz

Answers

Answer:

[tex]343 \div 1000 = 0.343[/tex]

wavelength is equivalent to the velocity divided by the frequency

Answer:

Hey mate.....

Explanation:

This is ur answer.....

Wind is the movement of air caused by the uneven heating of the Earth by the sun. ... Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth's surface toward the Equator to replace the heated air.

A spring of force constant 1500 Nm-l is acted
upon by a constant force of 75 N. Calculate
the potential energy stored in the spring.​

Answers

Answer:

1.876 J

Explanation:

First, let’s calculate the compression of the spring from the Hooke’s law:

F=kx,

here, F=75 N is the force acted on the spring, k=1500 N⁄m is the force constant of the spring, x is the compression of the spring.

Then, we get:

x=F/k=(75 N)/(1500 N/m)=0.05 m.

Finally, we can find the potential energy stored in the spring:

PE=1/2 kx^2=1/2∙1500 N/m∙(0.05 m)^2=1.875 J.

6. Sandy adds 3 sugar packets to her tea in order to make it sweeter. She stirs in the sugar and then takes a sip. She notices that not all the sugar was dissolved. What type of solution did she make?

A. Saturated B.Unsaturated C.Supersaturated D.Mildly saturated

Answers

Answer:

C.Supersaturated

Explanation:

There are three types of solution:

SATURATED SOLUTION:

It is the solution that contains maximum amount of solute dissolved in a solution in normal conditions.  

UNSATURATED SOLUTION:

It is the solution that contains less than the maximum amount of solute dissolved in a solution in normal conditions. It has space for more solute to be dissolved in it.

SUPERSATURATED SOLUTION:

It contains more than the maximum amount of solute dissolved in it. Such a solution has no capacity to dissolve any more solute under any conditions.

Since the sugar is no more dissolving in the tea and has settled down. Therefore, the solution is:

C.Supersaturated

A boy who is riding his bicycle, moves with an initial velocity of 5 m/s. ten second later, he is moving at 15 m/s. what is his acceleration

Answers

Answer:

1 m/s²

Explanation:

From the question,

Using

a = (v-u)/t.................... Equation 1

Where a = accelartion of the bicycle, v = Final velocity, u = initial velocity, t = time.

Given: v = 15 m/s, u = 5 m/s, t = 10 s

Substitute these values into equation 1

a = (15-5)/10

a = 10/10

a = 1 m/s²

Hence the acceleration of the bicycle is 1 m/s²

If spring has a spring constant of 500 N/m and is stretched .50 meters,how much energy is stored in the spring ((show work for full credit, show equation))

Answers

Answer:

The energy stored is: 62.5 Joules

Explanation:

Given

[tex]k = 500N/m[/tex] --- spring constant

[tex]x = 0.5m[/tex] --- stretch

Required

The amount of energy

This is calculated as:

[tex]U = \frac{1}{2} kx^2[/tex]

[tex]U = \frac{1}{2} * 500N/m * (0.5m)^2[/tex]

[tex]U = 250N/m * (0.5m)^2[/tex]

Answer:

The average speed for the runner B for the first 25 seconds was;

30/25 = 1.2 m/s

Explanation:

The average speed of an object is given by the following formula

[tex]Average \ speed = \dfrac{Total \ distance \ covered}{Total \ time \ taken \ to \ cover \ the \ distance}[/tex]

From the graph, we have;

The coordinates of the runner B at the start = (0, 0)

The coordinates of the runner B after 25 seconds = (25, 30)

The total distance covered by the runner B after 25 seconds = The difference between the position at 25 seconds and the origin which is 30 meters

∴ The total distance covered by the runner B after 25 seconds = 30 meters

The time it takes the runner B to cover the distance = The 25 seconds

[tex]\therefore \ For \ the \ runner \ B, the \ average \ speed = \dfrac{30 \ meters}{25 \ seconds} = 1.2 \ m/s[/tex]

The average speed for the runner B for the first 25 seconds = 30 m/(25 s) = 1.2 m/s.
