Answer:
6 Minutes 40 Seconds or 400 Seconds
Explanation:
Time to cover a distance of 5m = 1 Second
Time to cover a distance of 2000m = 2000÷5
= 400 Seconds
After converting 400 Seconds into minutes it will become 6 minutes 40 seconds.

Answer:
x = 25 / μ [ ft]
Explanation:
To solve this exercise we can use Newton's second law.
Let's set a reference system where the x axis is parallel to the road
Y axis
N_B + N_A - W_van - W_load = 0
N_B + N_A = W_van + W_load
X axis
fr = ma
a = fr / m
the total mass is
m = (W_van + W_load) / g
the friction force has the expression
fr = μ N_{total}
fr = μy (W_van + W_load)
we substitute
a = μ (W_van + W_load)
a = μ g
taking the acceleration let's use the kinematic relations where the final velocity is zero
v² = v₀² - 2 a x
0 = v₀² -2a x
x =
x =
x =
x = 25 / μ [ ft]
An Independent Group/ between-subjects design differs from a within-subjects design in that a between-subjects design. The correct option is B.
<h3>What is independent measure design?</h3>
Studying between subjects (or between groups): As various subjects are used to test each condition, each subject is only exposed to a single user interface. internal topic (or iterative measurement) The same topic evaluates every circumstance (that is, all user interfaces).
Each participant in a topic or intergroup design only encounters one condition, and the group differences between individuals under various conditions are compared. The in-subject design, in which every participant is exposed to every condition, is the antithesis of this.
