Answer:
When touching the bar magnet ,the nail gets attached to the magnet from its metallic field is used to connect when taylor touched the nail to the bar magnet,the magnetic fields were ranged,and made a temporary magnet.
Explanation:
Answer:
A. 70 Ns
B. 70 Kgm/s
C. 2.19 m/s
Explanation:
A. Determination of the impulse.
Force (F) = 20 N
Time (t) = 3.5 s
Impulse (I) =?
Impulse (I) = force (F) × time (t)
I = Ft
I = 20 × 3.5
I = 70 Ns
Thus, the Impulse is 70 Ns.
B. Determination of the change in momentum
Force (F) = 20 N
Time (t) = 3.5 s
Change in momentum =?
Change in momentum = m(v – u) = Ft
Change in momentum = Ft
Change in momentum = 20 × 3.5
Change in momentum = 70 Kgm/s
C. Determination of the final velocity.
Change in momentum = 70 Kgm/s
Initial velocity (u) = 0 m/s
Combined mass (m) = 32 kg
Final velocity (v) =?
Change in momentum = m(v – u)
70 = 32(v – 0)
70 = 32(v)
70 = 32v
Divide both side by 32
v = 70 / 32
v = 2.19 m/s
Thus, the final velocity is 2.19 m/s
It is found in and is integral to the retina. In the retina, retinal combines with ospin to form rhodopsin, which is found in the rod cells.
The best example of how neighboring continents seem to fit together like jigsaw puzzle pieces would be the west coast of Africa with South America. Hope this answers the question. Have a nice day. Feel free to ask more questions.
