A Painting is on the wall using 2 strings, hanging perpendicular to the floor. 5 The strings have a tension force of 490N each, what is the mass of the hanged painting?

100 kg

Explanation:

Two strings are used to hang the painting means the total weight of the painting is split into 2 the two string.

Each string has tension 490 N this means the total weight of the painting is

The tension of both the strings combimed will be the weight of the painting

Weight is given by

where,

m = Mass of the object

g = Acceleration due to gravity =

Here

w = 980 N

So, mass of the painting is 100 kg.

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

d

explanation:

v=uf/(u-f)
