Answer:
B. Similar, SAS
Step-by-step explanation:
Congruent angles are shown between proportional sides (the larger figure is 3 times the size of the smaller one).
The meaning of SAS is "side-angle-side", which describes the relationship of the similar parts.
Answer:
the mode is found by how much of the same number there is making the mode 1
the average is found by adding up all of it and dividing it by how many there is making it 4.2 if you need to round it, tha anwser is 4

The object compresses the spring up to 0.8577m.
<h3>What is Potential Energy?</h3>
Potential Energy is the energy possessed by an object at rest.
The object is falling from the rest and it is assumed that the friction on the ramp is zero and the air resistance is also considered to be zero so only the gravitational force acts and the total potential energy gets converted to Kinetic Energy.
The total amount of potential energy at the top of the ramp is given by
Ep=mgh
Ep=3 * 9.81 *5
Ep=147.15 Joules
This is equal to kinetic energy.
From the formula for elastic potential energy
The distance up to which the spring is compressed is determined
The force constant = 400N/m
147.15 =(1/2)k(x²)
294.3=(400)(x²)
0.73575=x²
x=0.8577 m
So, the object compresses the spring up to 0.8577m.
- When the object compresses the spring, the potential energy of the spring is converted into Kinetic Energy so it will push the object back again.
