The volume of the sphere is given by V = 4/3 * pie * r^3. We seek dr/dt that the rate of change of the radius with respect to time.
V = 4/3 * pie * r^3
Since we know the rate at which the volume changes wrt time. We can plug it in to find dr/dt.
dV/dt = 36pie. But dV/dt = 4/3 * pie * 3r^2 * dr/dt
So we have that dr/dt = (dV/dt) / 4/3 * pie * 3r^2
So dr/dt = (36pie)/ 4/3 * pie * 3(4)^2
dr/dt = 113.112/ 201.0864 = 0.5624
<span>The rate of conductivity is different among different substances, like aluminum, steel, and copper. Aluminum conducts heat the fastest at 910 j/kgaac. Steel is next and conducts heat at 450 j/kgaac. Copper conducts heat the slowest at 390 j/kgaac.</span>
Answer:
A planetesimal is an object formed from dust, rock, and other materials. The word has its roots in the concept infinitesimal, which indicates an object too small to see or measure. Planetesimals can be anywhere in size from several meters to hundreds of kilometers.
Protoplanets are thought to form out of kilometer-sized planetesimals that gravitationally perturb each other's orbits and collide, gradually coalescing into the dominant planets.
Answer:
If a car is moving at a <em><u>constant velocity of 10 m/s,</u></em> there will be no change in the velocity per time.
Acceleration is the rate of change of velocity
Acceleration=(Final velocity-Initial velocity)/Time
Acceleration=(10m/s-10m/s)/Time= <em><u>0 m/s²</u></em>
<h3>★ <u>0 m/s²</u> is the right answer. </h3>
