A dolphin maintains a constant speed of 2.0 m/s for 24 s while swimming in a straight line. It then reverses direction and returns to its starting point in 8 s. Its average speed and average velocity for the entire trip are

Complete Question

A student bikes to school by traveling first dN = 0.900 miles north, then dW = 0.300 miles west, and finally dS = 0.100 miles south.

Similarly, let d⃗ W be the displacement vector corresponding to the second leg of the student's trip. Express d⃗ W in component form.

Express your answer as two numbers separated by a comma. Be careful with your signs.

Answer:

The value is  [tex]dT  =  ( -0.3,  0.8)[/tex]

Explanation:

From the question we are told that

   The first displacement is  [tex]dN  =  0.900 \  due  \  North[/tex] i.e positive  y-axis

   The  second displacement is  [tex]dW =  0.300 \  miles  \  due \  west[/tex] i.e negative  x-axis

   The final displacement is  [tex]dS =  0.100 \  miles \ due \ south[/tex] i.e  negative  y-axis

Generally dW in component for is  

      [tex]dW =  (-0.3 ,  0)[/tex]  

Generally the  total displacement of the student is mathematically represented as

     [tex]dT  =  ( -0.3,  (0.90 - 0.10))[/tex]

      [tex]dT  =  ( -0.3,  0.8)[/tex]

Answer:

In MeV: 10.674 × 10^(34) MeV

In TeV: 10.674 × 10^(28) TeV

Explanation:

We are given that;

1.78 × 10^(-36) kg = 1 eV

We are now told that the blue whale has an average mass of 1.90 × 10^(5) kg

Thus, converting this mass of the blue whale to eV, we have;

(1.90 × 10^(5) × 1)/(1.78 × 10^(-36)) = 10.674 × 10^(40) eV

Now, converting to mega electron volts;

From conversions;

1 eV = 10^(-6) MeV

Thus,

10.674 × 10^(40) eV will be;

(10.674 × 10^(40) × 10^(-6))/1 = 10.674 × 10^(34) MeV

Also, converting to Tera electron Volts;

From conversion, we know that;

1 eV = 10^(-12) TeV

Thus;

10.674 × 10^(40) eV will give;

(10.674 × 10^(40) × 10^(-12))/1 = 10.674 × 10^(28) TeV

Explanation:

The interest in a pile of free bricks on Craigslist varies based on the needs and preferences of individuals in the local area, and posting clear details about the quantity, condition, and pickup arrangements can attract potentially interested parties.

Craigslist is an online classified advertising platform where users can post and find a wide range of listings for various goods, services, housing, jobs, and more. It operates on a local level, allowing individuals to connect within their specific geographic regions.

Interest in a pile of bricks on Craigslist would depend on the specific needs and preferences of individuals in the local area. While some people may find value in acquiring free bricks for construction or DIY projects, others may not have any use for them. It is difficult to predict the level of interest without knowing the specific context, location, and local demand for such materials. Posting the offer on Craigslist and providing clear details about the quantity, condition, and pickup arrangements can help attract potentially interested parties.

Therefore, Interest in a free pile of bricks on Craigslist depends on local individuals' needs and preferences, and posting clear details can attract potentially interested parties.
