Answer:
A,when the two air masses meet,the cold air cools the block if warm air,causing it to condense and form stratus clouds( blankets of blank clouds that form when air rises slowly e.g. a warm air mass meets a cold one). Eventually when the cloud becomes saturated precipitation falls from them(precipitation is moisture in any form that falls from the atmosphere).
Answer:
The magnetic force is increced, build a solinoid to see
Explanation:
Answer:
Runner A
Explanation:
Both B and C finished the race from 25 seconds
But A runner finished it from 20 seconds
The first thing we must do for this case is the sum of forces in a horizontal direction.
We have then:
Substituting values we have:
From here, we clear the mass of the object:
We now look for the weight of the object.
Where,
g: acceleration of gravity (9.8 m/s^2)
Substituting values:
Answer:
the weight of the object is:
option 4
