Which triangles are congruent according to the sas criterion?.
julia-pushkina [17]

<u>SAS Criterion:</u> If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

From the diagram you can see that:

<A ≅ <F ≅ <P

AB ≅ GF ≅ PQ

AC ≅ FE ≅ PR

This means that ΔABC, ΔFGE, and ΔPQR are congruent.

A 100-n weight is hung at the middle of a 4-m long horizontal clothesline. If the middle of the clothesline sags by 1 m, what is
Elena L [17]

The tension on each segment of the clothesline is :  110 N

<u>Given data : </u>

mass of object = 100 n  = 10 kg

Horizontal distance of clothesline = 4 m

middle of clothesline sag s by : 1m

<h3 /><h3>Determine the tension on each segment of clothesline</h3>

<u>First step</u> : calculate the horizontal angle made by the sagging

β = arctan ( 1 m / 2m )  ----- ( 1 )

  = arctan ( 0.5 )

  ≈ 26.57°

Note : Tension in th y axis ( Ty ) = Tsinβ

Therefore :

Tension on each segment can be calculated using the formula below

2Tsinβ - mg = 0

solve for T

T = mg / 2sinβ

  = ( 10 * 9.8 ) / 2 * sin 26.57°

  = 98 / 0.89

  = 110 N

Hence we can conclude that the tension on each segment of the clothesline is : 110 N

which best describes the object on the right? an iron bar a steel bar a bar magnet with its north pole on the left a bar magnet
amm1812

A bar magnet with its south pole on the left is describes the object on the right. A bar magnet's magnetic field is stronger at either pole of the magnet. When compared to the south pole, it is similarly strong at the north pole.

<h3 /><h3>What is bar magnet and its types?</h3>

There are two types of rectangular magnets fashioned like bars: cylindrical bar magnets and rectangular bar magnets.

Both types of bar magnets are capable of producing a powerful magnetic field. A rod magnet is a cylindrical bar magnet that is also known as a rod magnet.

Thus option D is correct.
