<span>It's A. Individuals with traits NOT suited for survival DON'T pass their traits to their offspring, because they don't survive and they DON'T HAVE OFFSPRING. That's why, after a while, most of the living individuals have traits that ARE suited for survival. THAT's what evolution says. It says nothing about individuals changing. Note this not my answer its the answer of the guy up above who wrote it in the comments instead of in an answer!</span><span />
The type of energy that is produced by the system that is described is heat energy. The correct answer is D.
Answer:
a= -1.01m/s^2
Explanation:
A) We define all the variables that are given,
In this way
Acceleration = a
We obtain the Normal assuming 5% of the potato reading scale, so
We add forces to reach equilibrium, and you get
** The notation of the symbols is done according to the notation of the graph
So,
B) When making pressure it is understood that the shape takes the perpendicular direction of the direction of the force that is performed. If the pressure remains constant, the scale will also increase in its measurement.
Answer:
<h3>3.06s</h3>
Explanation:
If I drop a paper clip from rest and it falls freely until it hits the ground with a speed of 30 m/s,we ae to find the time taken for the ball to drop. To do that we will use the equation of motion v = u + gt
v is the final velocity = 30m/s
u is the initial velocity = 0m/s (the object drops from rest)
g is the acceleration due to gravity = 9.81m/s²
time is the time taken
Substituting the given parameters into the formula;
30 = 0 + (9.81)t
30 = 9.81t
t = 30/9.81
t = 3.06secs
<em></em>
<em>Hence it will take the object 3.06secs in free fall</em>
