<span>It is light, easily shaped, strong, and inexpensive. Its ability to guard against contamination makes it useful in sterile medical environments such as hospitals.</span>
V=Vo+at (velocity=initial velocity plus acceleration multiplied by time)
40m/s=25m/s+a(3s)
-25 -25
15m/s=a(3s) divide by 3s on both sides
5m/s^2=a
Answer:
195
Explanation:
he can only apply as much force as his body mass so it would be 195
Answer:
5.74
Three significant figures
Explanation:
Distance =35.896m
Time =6.25
Speed = distance / time
= 35.896/6.25
=5.74
Answer:
<em>4.197 N</em>
<em></em>
Explanation:
current through the wires I = 700 A
distance between wires r = 70 cm = 0.7 m
length of each wire L = 30 m
force per unit length on the wires is given as
=
where u = permeability of vacuum = 1.256 m-kg-
F =
F = = <em>4.197 N</em>
