Yeah whats it doing for you?
Answer:
1800J
Explanation:
Step one:
given data
mass of bullet m= 3g= 0.03kg
initial velocity u = 400m/s
final velocity v= 200 m/s
Step two:
1.The bullet's lost kinetic energy went inside the tree.
2. The energy transferred is computed as
= initial KE- KE final
Initial KE= 1/2mu^2
Initial KE= 1/2*0.03*400^2
Initial KE= 1/2*0.03*160000
Initial KE= 1/2*4800
Initial KE= 2400J
KE final= 1/2mv^2
KE final= 1/2*0.03*200^2
KE final= 1/2*0.03*40000
KE final= 1/2*1200
KE final= 600J
KE transferred = 2400-600
KE transferred= 1800J
The answer is B) Sleep disorder. Notice that is says, "A condition that affects the ability to sleep or quaility of sleep." Meaning how much sleep you get. Also known as sleep disorder. Answer is B. Hope that helps :)
Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
