You need distance and time to find average speed.
Answer:
0.266 m
Explanation:
Assuming the lump of patty is 3 Kg then applying the principal of conservation of linear momentum,
P= mv where p is momentum, m is mass and v is the speed of an object. In this case
where sunscripts p and b represent putty and block respectively, c is common velocity.
Substituting the given values then
3*8=v(15+3)
V=24/18=1.33 m/s
The resultant kinetic energy is transferred to spring hence we apply the law of conservation of energy
where k is spring constant and x is the compression of spring. Substituting the given values then
Answer:
V = E * d
E = (200 J/C) / .024 m = 8330 J / C-m
1/2 m v^2 = V q potential energy of electron
v^2 = 2 * 200 J/C * 1.6E-19 C / 9.11 E-31 kg
v^2 = 400 * 1.6E-19 / 9.11 E-31 N-m / kg
v = 8.4E6 m/s
Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass (gasp, shudder, the horror!) then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.

Answer:
charge on first sphere = net charge /2 = (-0.2+0.6) /2
= +0.2C
