Answer:
L = 6.032 m
Explanation:
The resistance of a wire is given by
R = ρ L / A
done ρ is the resistivity of matter, L is the length and A is the area
L = R A /ρ
the area of a circle is
A = π r² = π d² / 4
L = R π d² / 4ρ
in the problem they indicate the resistance of 240 Ω, the diameter of 0.040 mm and the resistivity of 5 10⁻⁷ Ω / m
Let's reduce the diameter to SI units
d = 0.040 mm (1 m / 1000 mm) = 4 10⁻⁵ m
let's calculate
L = 240 π (4 10⁻⁵) 2 / (4 5 10⁻⁷)
L = 6.0319 m
L = 6.032 m
Answer:
The right answer is "1.369 m/s²".
Explanation:
The given values are:
Distance (s)
= 260 m
Initial speed (u)
= 26 m/s
Reaction time (t')
= 0.51 s
During reaction time, the distance travelled by locomotive will be:
⇒
Remained distance between locomotive and car:
⇒
Now,
The final velocity to avoid collection is, V = 0 m/s
From third equation of motion:
⇒
On putting the estimated values, we get
⇒
⇒
⇒
⇒
⇒
The formula we will be using is;F = G m1 m2 / r^2
F earth = 308N
F moon = G me m2 / (81.3 * 0.27^2 RE^2) = 1/5.927 G me m2 / RE^2 = F earth / 5.927 = 52 N is the force of the earth
So the answer in this question is 52 N.
The part of the electromagnetic spectrum has a shorter wavelength than ultraviolet light is x-rays.
