In the Earth's mantle, heat is transferred in large convection currents. Within these currents "hotter rock rises and cooler rock sinks".

Option B

Explanation:

Heat rises occur and the hotter rock gets farther away from the Earth's overheated core it starts to chill out and continues to sink back towards the Earth's overheated center where it gets reheated and also the entire procedure begins again. It's what a current in convection is.

Convection currents are part of what keeps the Earth's atmosphere through global circulation. The convection currents contribute to conditions in the air and sea. Magma travels in convection currents at Earth's mantle. The hot cores heat the above substance, allowing it to rise to the crust where it cools.

Clara rushes 30m to a truck then turns and walks back. Total travel is 120s what is her average velocity?

navik [9.2K]

Taking into account the definition of velocity, Clara's average velocity is 0.5 m/s.

<h3>Definition of velocity</h3>

Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction. So it is considered a vector magnitude.

In other words, the velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:

velocity= distance traveled÷ time

<h3>Average velocity of Clara</h3>

Clara rushes 30 m to a truck then turns and walks back. Total travel is 120s. Then, you know:

distance traveled= 30m rushing + 30m walking back= 60 m
time= 120 s

Replacing in the definition of velocity:

velocity= 60 m÷ 120 s

Solving:

velocity= 0.5 m/s

Finally, Clara's average velocity is 0.5 m/s.

Kamal, Kamala, Krishna invert a sum of RS= 30,000 on a business in the ratio 2 : 3 : 5. Find the each of their investment.

Crazy boy [7]

Here's the solution,

Let the shares be 2x, 3x and 5x according to their shared investment ratio,

now, we know :

=》2x + 3x + 5x = 30000

=》10x = 30000

=》x = 3000

So, value of x = 3000

hence, the share of each shareholder is :

kamal = 2x = 6000
kamala = 3x = 9000
Krishna = 5x = 15000

i hope it helped.....
