Answer:
Lion Average speed:60 km/h
Explanation:
Answer:a)1.11×10^-21Nm
b) 1.16×10^-3m
Explanation:see attachment
Velocity:
60 meters/ 5 seconds= 12 meters/second
Velocity=12meters/second
(60 meters divided by 5 seconds equals 12 meters per second)
Hope this helps!
R = 2.06 mm = 2.06 x 10^(-3) m
Q = 1.6 x 10^(-19) C
v = 2.5 x 10^(-5) m/s
I = 8 A = 8 C/s
A = r² π = ( 2.06 x 10^(-3) ) ² x 3.14 = 13.325 x 10^(-6 ) m² =
= 1.3325 x 10^(-5) m²
I = n Q v A
n = I / (Q v A)
n = 8 C/s / ( 1.6 x 10 ^(-19) * 5.4 x 10^(-5) * 1.3325 x 10^(-5) ) =
= 0.694 x 10^(29) m^(-3)
n = 6.94 x 10^(28) m^(-3)
