The relationship between voltage, current, and resistance is described by Ohm's law. The equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.
Answer:
Primitive material was formed in the early stage of the solar system, before planets cooled off enough to differentiate elements of different density. It was not subject to great heat or pressure after it formed.
We can identify primitive meteorites by their composition, primitive meteorites are usually undifferentiated stones, with some metallic grains mixed in. Some primitive meteorites are darker, carbonaceous stones.
The shadow that will be protected on the ground will represent the hawk's horizontal position. therefore it will move at the hawk's horizontal velocity component, which is:
5*cos(60) = 2.5 m/s
Answer:
a).p=15.67kg*m/s
b). F=7.83N
Explanation:
change in momentum is the subtraction from "after momentum" of the "before momentum" as momentum is a vector quantity this is a vector subtraction.
initial momentum of ball
m1v1 = (0.145)(44.0) = 6.38 kg-m/s
after momentum
m1v2 = (0.145)(64.0) = 9.28 kg-m/s
since these momentums are 180° opposite one must be called negative so their difference
6.38+9.28= 15.67 kg-m/s
change in momentum = 15.67 kg-m/s ANS a1
Impulse = change in momenutm = 15.67 ANS a2
b)
Impulse =Favg*t
I=(2.00)Favg
Impulse from (a2) = 15.67
Favg = 15.67/2.00 =
F= 7.83 N
