Answer:

Explanation:
Given:
- mass of the object,

forces by two mutually perpendicular ropes of the attached to the object:
<u>Now we find the resultant force effect due to the two given forces:</u>



<u>Now the acceleration will be due to this resultant force:</u>



Answer:
Since both start with the same vertical velocity from the same position with the same acceleration they will reach the lake at the same time.
The average acceleration between t = 5.6 s and t = 8.5 s is 2.31 m/s²
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
An object is moving with initial velocity u =5.7 m/s and its final velocity v= -1.0 m/s.
Time taken for the change in speed, t= 8.5 - 5.6 = 2.9 seconds
The acceleration is given by
a = (-1 - 5.7)/ 2.9
a = - 2.31 m/s²
|a | = 2.31 m/s²
Thus, the object's acceleration is 2.31 m/s²

The best answer is
A) <span>The atoms in the mineral get rearranged
Over time, and under great pressure, the atoms of a substance can become rearranged, forming a new substance. For example, the intense pressure that carbon underground experiences, perhaps in the form of coal, can rearrange the atoms of the substance to create a diamond. </span>
143m/s if you just perhaps by what you know you'll figure it out
