Answer:

Therefore the mass of the object is 56.78 kg.

Step-by-step explanation:

Mass: Mass of an object is physical property.Mass of an object can't change with respect to place.

The S.I unit of mass is Kg

But the weight of an object changes with respect to place.

Weight= mass× gravity

The gravitational force varies  place to place.

For this reason the weight of an object is not constant.

The value of g is 9.8 m/s².

Unit of weight:

Weight = mass × gravity

           =Kg×m×s⁻²

           =N

Given, weight= 557 N , g= 9.81 m/s² and mass=?

Weight = mass × gravity

⇒557= mass× 9.81

\Rightarrow mass=\frac{557}{9.81}

⇒mass= 56.7787≈56.78

Therefore the mass of the object is 56.78 kg.

Answer:

The measure of side MO is 8 unit

Step-by-step explanation:

Given as :

In the Triangle ΔMOP ,

∠P = 90°

∠M = 60°

The perimeter of  ΔMOP = 12 + 4√3

Now, From figure , in Triangle ΔMOP

∠O = 180° - ( ∠P + ∠M )

or, ∠O = 180° - ( 90° + 60° )

or,  ∠O = 180° - 150°

∴ ∠O = 30°

<u>Now, from Triangle</u>

Sin 90° = \dfrac{\textrm perpendicular}{\textrm hypotenuse}

Or, Sin 90° = \dfrac{\textrm OP}{\textrm OM}

Or,  \dfrac{\textrm OP}{\textrm OM} = 1

Again

Sin 60° = \dfrac{\textrm perpendicular}{\textrm hypotenuse}

Or, Sin 60° = \dfrac{\textrm OP}{\textrm OM}

Or,  \dfrac{\textrm OP}{\textrm OM} = \dfrac{\sqrt{3} }{2}

Similarly

Sin 30° = \dfrac{\textrm base}{\textrm hypotenuse}

Or, Sin 30° = \dfrac{\textrm PM}{\textrm OM}

Or,  \dfrac{\textrm PM}{\textrm OM} = \frac{1}{2}

So, The ratio of the sides as

PM : MO : OP = 1 : 2 : \sqrt{3}

Let  PM = x

MO = 2 x

OP = x\sqrt{3}

Now, from question

The perimeter of triangle ΔMOP = 12 + 4√3

I.e, The sum of sides of triangle ΔMOP = 12 + 4√3

or, PM + MO + OP = 12 + 4√3

or, x + 2 x +  x\sqrt{3} = 12 + 4√3

or, 3 x  +  x\sqrt{3} = 12 + 4√3

Or, x ( 3 +\sqrt{3} ) = 4 ( 3 +\sqrt{3} )

Now, equating both side we get

x = 4

So, The measure of side MO = 2 x

I.e The measure of side MO = 2 × 4 = 8 unit

Hence The measure of side MO is 8 unit   Answer
