Distance is 50 km
Displacement is 10 km
<u>Explanation:</u>
Given:
Distance toward south, x = 25 km
Distance towards west, y = 10 km
Distance towards north, z = 15 km
(a) Total distance, D = ?
Total distance, D = x + y + z
D = 25 + 10 + 15
D = 50km
(b) Displacement, d = ?
Displacement = final position - initial position
= 10 - 0 km
= 10km
Answer:
Explanation:The work done is twice as great for block B because it is moved twice the ... Equal forces are used to move blocks A and B across the floor. ... Does the normal force of the floor pushing upward on the block do any work? ... Suppose that the mass is halfway between one of the extreme points of its motion and the center point.
Answer:
<h2>2.22 kPa</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>2.22 kPa</h3>

In the Earth's mantle, heat is transferred in large convection currents. Within these currents "hotter rock rises and cooler rock sinks".
Option B
<u>Explanation:</u>
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.
