<span>AS T1,T2,T3 are the tensions in the ropes,assuming that there are Three blocks of mass 3m, 2m, and m.T3 is the string between 3m and 2m,T2 is the string between 2m and m ,T1 is the string attached to m thus T1 pulls the whole set of blocks along, so it must be the largest. T2 pulls the last
two masses, but T3 only pulls the last mass, so T3 < T2 < T1.</span>
Answer:
we know that current = charge/time
Explanation:
therefore,
A = 8000/120
A => 66.666.... amperes
Answer:
False.
Explanation:
Yes the magnitude of a vector is always positive , but a vector consists of
when two vectors are added their direction may be opposite to each other For example-
,
then their resultant
This resultant vector's x and y component equal to y and x component of vector b so its magnitude will be equal to magnitude of vector b.
Therefore, the resultant magnitude not necessary equal to the magnitude of either vector.
It is called a metric system!
Cryosphere is the sphere of earth that includes icebergs.
There are 5 main sphere of earth:
- Atmosphere (sphere that comprises of air. It is further divided into subsphere)
- Biosphere (Sphere that consists of living thing)
- Geosphere/ Lithosphere (sphere that counts land, rocks and minerals etc.)
- Hydrosphere (sphere that includes water bodies such as sea, river etc.)
- Cryosphere (sphere that includes frozen part of water such as icebergs. Arctic ocean and continent of Antarctica are example of cryosphere).
