Answer:
Direction
Explanation: Hope this helps!
Considering north as positive Y axis
First 10 miles north means a positive 10 displacement along y direction
Second 20 miles south means a negative 20 displacement along y direction
Third 5 miles south means a positive 5 displacement along y direction
So total displacement = 10 - 20 + 5 = -5 miles displacement
So position vector of the final position = - 5 j
An example of biological weathering is the widening of gaps
in rocks caused by tree roots since pressure or stress is exerted on the
rocks due to the growing plant roots. The pressure is exerted by a biological
process (i.e., growing roots), even though the process is physical.
Plants and animals and its action speeds up mechanical and or
chemical weathering, which in turn causes biological weathering.
<span>With the help of the chemicals
that are produced by the tiniest bacteria, algae and liches, the rocks which they
live in are also broken down by them in order to get the nutrients they need.</span>
Solid mixture consists of two or more different solid matter such as fruit salad and vegetable salad liquid mixture consists of two or more different liquids such as mixture of vinegar and water , mixture of oil and water , mixture of oil and vinegar ( dressing of salad ) . Solid mixtures are easier to separate , because you can physically or magnetically separate them ... liquids are a little more hard & liquids
Answer:
A car covers distance of 291.2 m if the car is travelled at<em> speed of 56 m/s in 5200 milliseconds.
</em>
<u>Explanation:
</u>
To find the distance covered by the car we use the the relationship between speed, time and distance is 
. Given, speed = 56 m/s and time = 5200 milliseconds. Covert milliseconds into seconds we can get by dividing it with 1000 = 
= 5.2 seconds.
Now, 
Thus a car can travel 291.2 m if the car is travelled at speed of <em>56 m/s in 5200 milliseconds.
</em>
