A tape dispenser is a wheel and axis due to the fact that it has a hole in the middle of the tape, which is held together by a rod sticking through the hole attached to the dispenser.

If the density of an object is 30 g/cm3 and its volume is 10 cm3, what is its mass in grams?
Inga [223]
Density = Mass / Volume

Mass = Density * Volume

Mass =  30 g/cm³  *  10 cm³ = 300 g

Mass = 300 g

If we throw a tennis ball and a bowling ball, would the bowling ball require more or less force than the tennis ball to reach th
andre [41]
The bowling ball would need less because it has more of a Gravitational pull to the ground than the tennis ball does. The letters represent force = mass and acceleration. I hope this helps ✨✨

How fast can the 140 a current through a 0.200 h inductor be shut off if the induced emf cannot exceed 80.0 v?
Vesna [10]
Recall that to compute for the emf of a circuit given current and inductance, we must recall that 

emf = - M \frac{\Delta I }{\Delta t}

where I is the current (A), M is the mutual inductance (h), and t is the time (ms). Since the current must not exceed 80.0 V, we have

80.0 \geq 0.200(\frac{140}{t})
t \geq \frac{28.0}{80}
t \geq 0.35

From this, we see that it must take at least 0.35 ms so it doesn't exceed 80 V.
Answer: 0.35 ms

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.
