Important thing when making a lava lamp are the two liquids with different density so that it would not mix and that it would expand when heated. The movement of the orange liquid is called convection. if you will not heat the orange one, it till just stay on the stop and not go under tha water.
Answer:
I think that the liquids molecules are slowing down. Hope this helps!

Answer:
<em>F equals 3 N and the object remains stationary</em>. (second option in the list)
Explanation:
For sure to cancel acting forces, F must be 3N pointing up. But with regards to the object stationary or not, the question is tricky. We could have a ZERO net force applied, and the object moving at constant speed, which could still verify Newton's Laws. But considering the first answer option that refers to vertical motion upward where the object could be gaining potential energy, the most accurate response is that the force F has to be 3 N pointing up to make the object in equilibrium, and no motion in the vertical axis.
Answer:
5.69755 rad/s²
Explanation:
r = Radius = 1.3 m
v = Velocity of the hammer = 22 m/s
n = Number of revolutions = 4
Angular displacement
= Initial angular speed = 0
Final angular speed
Angular acceleration
Angular acceleration is given by 5.69755 rad/s²
