Answer: 4 times grease
Explanation: Force F= C · q1·q2/r². C = Coulomb's constant.
If charges double you have 2q1 and 2q2.
Answer:
261.3 m/s
Explanation:
Mass of bullet=m=15 g=
1 kg=1000g
Mass of block=M=3 kg
d=0.086 m
Total mass =M+m=3+0.015=3.015 kg
K.E at the time strike=Gravitational potential energy at the end of swing

Using g=
Substitute the values




Velocity after collision=V=1.3 m/s
Velocity of block=v'=0
Using conservation law of momentum

Using the formula




They begin to adapt into their new location. They then end up having adaptations to help them survive.
Yes because the heat is to hot and would melt the earth layers so it would go through
Brainiest plz
By using ramps you can easily push or pull the object up the ramp.
