Hi there!
Recall the equation for momentum:
p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
We can calculate each object's momentum and compare.
Cement truck:
Race car:
<u>Since 100,000 > 90,000, the cement truck has the greater momentum.</u>
Answer:
a)
Explanation:
Given paraeters are:
R = 25 cm
d = 4.7 mm
f = 60 Hz
= 160 V
a)
Where Hz and
V
For
Since
From Ampere's Law:
where
So at ,
For maximum B, cos(2πft) = 1. Hence,
T
b) From r = 0 to r = R = 0.025 m, by Ampere's Law, the equation will be:
From r = R = 0.025 m to r = 0.1 m, by Ampere's Law, the equation will be:
The plot is given in the attachment.
