Answer:
Explanation:
An inelastic collision is one in which the internal kinetic energy changes (it is not conserved) . The two objects come to rest after sticking together, conserving momentum. But the internal kinetic energy is zero after the collision.
Answer:
d = 2*0.87 = 1.75 cm
Explanation:
by using flow rate equation to determine the speed in larger pipe
= 591.10 cm/s
= 5.91 m/s
by Bernoulli's EQUATION
solving for v2
v2 = 10.53 m/s
diameter can be determine by using flow rate equation
r = 0.87 cm
d = 2*0.87 = 1.75 cm
In the conservation of mass, mass is never created or destroyed in chemical reactions in the same way water is not created or destroyed it is only transferred from one form to another and its mass is always conserved.
Answer:
10 m/s
Explanation:
Momentum before collision = momentum after collision
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(8 kg)(8 m/s) + (6 kg)(6 m/s) = (8 kg)(5 m/s) + (6 kg) v
64 kg m/s + 36 kg m/s = 40 kg m/s + (6 kg) v
60 kg m/s = (6 kg) v
v = 10 m/s
Answer:mostly likely from volcanos
Explanation:
when the volcano erupts the magma becomes lava and cools making igneous rocks
