0.119cm/s is the radius of the balloon increasing when the diameter is 20 cm.
<h3>How big is a circle's radius?</h3>
The radius of a circle is the distance a circle's center from any point along its circumference. Usually, "R" or "r" is used to indicate it.
A circle's diameter cuts through the center and extends from edge to edge, in contrast to a circle's radius, which extends from center to edge. Essentially, a circle is divided in half by its diameter.
dv/dt = 150cm³/s
d = 2r = 20cm
r = 10cm
find dr/dt
Given that the volume of a sphere is calculated using
v = 4/3πr³
Consider both sides of a derivative
d/dt(v) = d/dt( 4/3πr³)
dv/dt = 4/3π(3r²)dr/dt = 4πr²dr/dt
Hence,
dr/dt = 1/4πr².dv/dt
dr/dt = 1/4π×(10)²×150
dr/dt = 1/4π×100×150
dr/dt = 0.119cm/s.

As per the law of conservation of energy, no energy is created or destroyed. Therefore, we can conclude that the remaining 92% of energy released in electricity generation from steam power plants is converted to other, non-utilizable forms of energy. Such forms include sound energy or thermal energy between the moving parts of the plant.
Yes a igneous rock can be changed into another igneous rock. the reason behind it is when rocks melt they become magma or lava. when lava flows on the surface of the earth it crystallizes quickly and makes small crystals. but when they cool slower they make larger crystals. yes igneous rocks can change but only through extreme temperatures.
Answer:
The direction of the B-field is in the +y-direction.
Explanation:
The corresponding formula is
This means, we should use right-hand rule.
Our index finger is pointed towards +x-direction (direction of velocity),
our middle finger should point towards the direction of the B-field,
and our thumb should point towards the +z-direction (direction of the force).
Since our middle finger in this situation points towards +y-direction, the B-field should be in +y-direction.
Answer:
In mine I said to build the boat accordingly based on what is going to be in it
Explanation:
just remember the density of the boat cannot change but the volume and the mass can
