Answer:
length is 23.228091 m
Explanation:
Given data
radius = 0.791 mm = 0.791 × 
m
current = 9.25 A
voltage = 1.20 × 10² V
to find out
resistance and length of wire
solution
we know the resistance formula that is
resistance = voltage / current
resistance = 1.20 × 10² /9.25
resistance = 12.97
so resistance is 12.97 ohm
and length of nichrome wire formula is
length = resistance × area / specific resistance of wire
so specific resistance of wire we know = 1.1 × 
and area = 
× r² = × (0.0791× )²
area = 1.97 ×
length = 12.97 × 1.97 × / 1.1 ×
so length is 23.228091 m
Answer:
From the formular of magnetic force:
• F » magnetic force, B » magnetic flux density, I » current, l » length [ assume l = 1 m ]
Since the wave is moving to the right, we can draw the position of the wave at the next instant by simply replicating the wave, but shifted to the right.
In this way, we can know how each point has moved in the next instant. It can be seen that particles at both 0.5 m and 1.0 m will move upward at the next instant but the largest upward change in displacement occurs at a distance of 0.5 m.
At 1.5 m and 2.0 m, the particles would move downward in the next instant, and the maximum downward velocity is at 1.5 m.
Answer:
W = 14.8 kJ
Explanation:
W = F S cos ∅
W = 4113 x 3.99 x cos 25.5
W = 16410.87 x 0.9025 = 14810.8 J or 14.8 kJ
