Answer:
Approximately
(approximately
) assuming that the magnetic field and the wire are both horizontal.
Explanation:
Let
denote the angle between the wire and the magnetic field.
Let
denote the magnitude of the magnetic field.
Let
denote the length of the wire.
Let
denote the current in this wire.
The magnetic force on the wire would be:
.
Because of the
term, the magnetic force on the wire is maximized when the wire is perpendicular to the magnetic field (such that the angle between them is
.)
In this question:
(or, equivalently,
radians, if the calculator is in radian mode.)
.
.
.
Rearrange the equation
to find an expression for
, the current in this wire.
.
Longitudinal design is defined as a special kind of systematic observation, implemented by correlational researchers, which involves the tasks of obtaining measures of variables of interest in multiple waves over time.
<u>Explanation:
</u>
Longitudinal design is one of the known systematic observation pattern followed by the correlational researchers in which a subject of experiment is observed for a significantly long span.
The three types of longitudinal design are: panel study, cohort study and retrospective study. The complete design involves the multiple set of observations over a variable or subject. Longitudinal design is often used in clinical psychology to study rapid fluctuations in the behaviour.
I believe it'd accelerate at 1.25 m/s^2 instead of 1, as it lost 1/4 of its mass (.25), so now it is .25 of 1 faster.
Answer:
<u>NORMAL DRIVER: </u>d = 73.3 ft
<u>DRUNK DRIVER: </u>d = 172.3
Explanation:
<u>NORMAL DRIVER:</u>
Distance covered in initial 0.75s = 0.75s *44 = 33ft
USING THE THIRD EQUATION OF MOTION
V^2-U^2 = 2as
0-(44)^2 = 2 (-24) s
s = 1936/48 =40.3 ft
d = 33 + 40.3 = 73.3 ft
<u>DRUNK DRIVER:</u>
Distance covered in initial 3s = 3s *44 = 132 ft
USING THE THIRD EQUATION OF MOTION
V^2-U^2 = 2as
0-(44)^2 = 2 (-24) s
s = 1936/48 =40.3 ft
d = 132 + 40.3 = 172.3 ft
D. there would be less energy transferred to the higher trophic levels
