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.
.
Answer:
An opposing force caused by friction produced a lower acceleration than calculated.
Explanation:
Latitude or distance from the equator. Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.
If the answer is correct please mark as brainlist
hi <3
i believe i explained this answer properly in my last answer but it would be 4kg and 2400m as these are the SI units for these values.
hope this helps :)
Answer:
Ф = 239.73 rad
Explanation:
α = 12 + 15×t
W = ∫α×dt
= ∫(12 + 5×t)×dt
= 12×t + 2.5×t^2
then:
Ф = ∫W×dt
= ∫(12×t + 2.5×t^2)dt
= 6×t^2 + 5/6×t^3
therefore the angle at t = 4.88s is:
Ф = 6×(4.88)^2 + 5/6×(4.88)^3
= 239.73 rad
