Physics
1 answer:
Murljashka [212]2 years ago
5 0

Answer:

f = 400 / 5 s = 80/sec        frequency of revolution

P = 1/f = 1/(80/sec) = .0125 sec   period of revolution

Rank the tensions in the ropes, t1, t2, and t3, from smallest to largest, when the boxes are in motion and there is no friction
gizmo_the_mogwai [7]
<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>

Since vectors always have positive magnitudes, the sum of two vectors must have a magnitude greater than the magnitude of either
Natasha2012 [34]

Answer:

False.

Explanation:

Yes the magnitude of a vector is always positive , but a vector consists of

  • magnitude
  • direction

when two vectors are added their direction may be opposite to each other For example-

a=3i+3j

b=3i-6j ,

then their resultant

r=b+a\\r=3i+3j+3i-6j\\r=6i-3j

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.

nirvana33 [79]

Cryosphere is the sphere of earth that includes icebergs.

There are 5 main sphere of earth:

  1. Atmosphere (sphere that comprises of air. It is further divided into subsphere)
  2. Biosphere (Sphere that consists of living thing)
  3. Geosphere/ Lithosphere (sphere that counts land, rocks and minerals etc.)
  4. Hydrosphere (sphere that includes water bodies such as sea, river etc.)
  5. Cryosphere (sphere that includes frozen part of water such as icebergs. Arctic ocean and continent of Antarctica are example of cryosphere).
