Answer:
5 meters per second
Explanation:
5m is the distance
5m west is the vector
5m per second is the velocity
5m per second west is unknown
Answer:
The angular speed of the reel is 11.33 rad/s
Explanation:
Given
The fisherman takes t = 8.4 s to wind distance x = 2.9 m into a circle radius of r = 3 cm = 0.03 m
Than the tangencial speed equals the change in the distance to the time
v =
= ![\frac{2.9 m}{8.4 s} = 0.34 \frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7B2.9%20m%7D%7B8.4%20s%7D%20%3D%200.34%20%5Cfrac%7Bm%7D%7Bs%7D)
Knowing the tangencial velocity is proportional to the radius r and the angular velocity
v = r*w
w = ![\frac{0.34 m/s}{0.03 m} = 11.33 \frac{rad}{s}](https://tex.z-dn.net/?f=%5Cfrac%7B0.34%20m%2Fs%7D%7B0.03%20m%7D%20%3D%2011.33%20%5Cfrac%7Brad%7D%7Bs%7D)
Answer:
V = 9.682 × 10^(-6) V
Explanation:
Given data
thick = 190 µm
wide = 4.20 mm
magnitude B = 0.78 T
current i = 32 A
to find out
Calculate V
solution
we know v formula that is
V = magnitude× current / (no of charge carriers ×thickness × e
here we know that number of charge carriers/unit volume for copper = 8.47 x 10^28 electrons/m³
so put all value we get
V = magnitude× current / (no of charge carriers ×thickness × e
V = 0.78 × 32 / (8.47 x 10^28 × 190 × 1.602 x 10^(-19)
V = 9.682 × 10^(-6) V
A good heat insulator absorbs all, or almost all, of the heat energy
from any heat that flows through it.
A good electrical insulator absorbs all, or almost all, of the energy
from any electric current that flows through it.
