Answer: the weight would be 4.6 (I think i don’t know))
Explanation:
The amount of solid does not affect how you are describing the solid so a is the answer
Answer:
The acceleration of the sprinter is 1.4 m/s²
Explanation:
Hi there!
The equation of position of the sprinter is the following:
x = x0 + v0 · t + 1/2 · a · t²
Where:
x = position of the sprinter at a time t.
x0 = initial position.
v0 = initial velocity.
t = time.
a = acceleration.
Since the origin of the frame of reference is located at the starting point and the sprinter starts from rest, then, x0 and v0 are equal to zero:
x = 1/2 · a · t²
At t = 9.9 s, x = 71 m
71 m = 1/2 · a · (9.9 s)²
2 · 71 m / (9.9 s)² = a
a = 1.4 m/s²
The acceleration of the sprinter is 1.4 m/s²
The type of investigation is she is conducting by determining the period in which it is from is referred to as the geologic age.
<h3>What is Geologic age?</h3>
This is defined as the time period in which the fossil was present on the earth and can be done using various methods such as radiometric dating methods etc. The age gotten will help scientists to ascertain different information about the organism in this context.
Fossil on the other hand which is the remains of organisms preserved in the earth crust can be studied to find out the differences in the features of organisms and how they were able to adapt to the changing environmental conditions.
