The fastest growing plant on record is the Hesperoyucca whipplei. Suppose a plant of this type grows 3.7 m in 14 days. What is i
1 answer:
Answer:
Growth rate in micrometers per second is 3.05.
Given:
Growing length = 3.7 meter
Time = 14 days
To find:
Growth rate = ?
Formula used:
Growth rate =
Solution:
Growth rate =
Growing length = 3.7 × micrometer
Time = 14 × 24 × 60 × 60
Growth rate =
Growth rate = 3.05 micrometer per second
Growth rate in micrometers per second is 3.05.

Answer:
The object will travel 675 m during that time.
Explanation:
A body moves with constant acceleration motion or uniformly accelerated rectilinear motion (u.a.r.m) when the path is a straight line, but the velocity is not necessarily constant because there is an acceleration.
In other words, a body performs a u.a.r.m when its path is a straight line and its acceleration is constant. This implies that the speed increases or decreases uniformly.
In this case, the position is calculated using the expression:
x = xo + vo*t + ½*a*t²
where:
- x0 is the initial position.
- v0 is the initial velocity.
- a is the acceleration.
- t is the time interval in which the motion is studied.
In this case:
- x0= 0
- v0= 0 because the object is initially stationary
- a= 6
- t= 15 s
Replacing:
x= 0 + 0*15 s + ½*6 *(15s)²
Solving:
x=½*6 *(15s)²
x=½*6 *225 s²
x= 675 m
<u><em> The object will travel 675 m during that time.</em></u>
