As per angular momentum conservation we can say

L_i = L_f

here we know that

mv_1r_1 = mv_2r_2

we know that

v_1 = 1.1 m/s

r_1 = 0.6 m

v_2 = ?

r_2 = 0.15 m

now from above equation

2(1.1)(0.6) = 2(v_2)(0.15)

v_2 = \frac{(1.1)(0.6)}{0.15}

v_2 = 4.4 m/s

so speed is 4.4 m/s

when an incandescent light bulb is turned on, its thin wire filament heats up quickly. as the temperature of this wire filament
Leno4ka [110]

Well, we usually assume that the resistance of a circuit component
is constant and doesn't change.  But the truth is that for anything
that conducts current, its resistance always increases somewhat
when it warms up. 

For things like light bulbs, electric toasters, space heaters, electric
stove burners, the heat coils in a blow-dryer ... anything that's
designed to be really hot when it's doing its job ... the resistance
of those things increases significantly when they come up to their
operating temperatures.

harina [27]
Convention is known as one of the driving forces of atmospheric circulation. Convection is defined as the heat transfer due to bulk movement of the molecules within fluids like liquids and gases, uncluding th molten rock. Convention takes place through diffusion, advection or can be both and it is usually a domination form of heat that transfer into liquids and gases.

What are the similarities between strong nuclear force and weak nuclear force
Artemon [7]
Alike because they both act on the quarks making up the nucleons and they have very short ranges. The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei. Which also makes them very different
