Answer: B. Increases
Explanation:
An electron is a negatively charged particle, while a proton is positively charged.
Opposites attract so as it approaches the proton the force of attraction will increase.
Using formula:
I=(1/2)*M*(R^2+r^2)
<span>I=0.5*0.715kg*[(12.7cm)^2+(10.7cm)^2] </span>
<span>I=98.6 kg*cm^2</span>
Answer:
The block is moving 0.564 m/s after the bullet emerges it.
Explanation:
<u>Step 1:</u> Data given
Mass of the bullet m = 4.86 grams = 0.00486 kg
Initial speed of the bullet u = 306 m/s
Mass of the wooden block m' = 1.37 kg
Final speed of the bullet v = 147 m/s
Initial speed of the block u'= 0 m/s
Final speed of the block = v'
<u>Step 2:</u> conservation law of momentum
mu + m'u' = mv + m'v'
0.00486*306 + 1.37 * 0 = 0.00486*147 + 1.37*v'
1.48716 = 0.71442 + 1.37 v'
0.77274 = 1.37 v'
v' = 0.564 m/s
The block is moving 0.564 m/s after the bullet emerges it.
Mass is how heavy is an object is
Over time waves can make large cracks larger and eventually pieces of rock to break off forming sea caves. Eventually waves erode the base of a cliff so the rock above collapses which creates a wave-cut cliff. Sea arches can also be created.
