You had me at Brainliest, and the answer would be series, hope that helps.
Answer:
1.47kW
Explanation:
F = 300N, s = 50m, v = 5.9m/s
P = W/t
= (F× )/t
= F × v
= 300 × 5.9
= 1470Watt
= 1.47kW
The question is not complete so i have attached it.
Answer:
The light source is 2 cm from the bottom of the lamp
Explanation:
From the attached image, we can see that the parabola opens up with its vertex at the origin.
Now, the standard form of equation for a parabola is:
x² = 4ay
Looking at the parabola in the attachment, the top right edge of the lamp has a coordinate of (12,18)
Thus, we have;
12² = 4a(18)
144 = 72a
a = 144/72
a = 2
Looking at the parabola again, the line of symmetry is at x = 0
Thus, axis of symmetry is at x = 0.
Thus, focus is at (0, 2)
So, if the light source is placed at the focus, the distance of the light source from the bottom of the lamp is 2 cm
Because the handle bars have nothing to do with the force of the pedals
I don’t really know the answer cause I need more information about the question
