SVEN [57.7K]

When you add up (20N down) and (10N up),
you get a sum of (10N down).

The mass of the object has no effect on the forces.

Now ... I see 5 points for the answer.
Where are the other 25 coming from ?

What do we mean by "Ohmic"?

CaHeK987 [17]

Answer:

c. "Ohmic" is when the plot of I [Amp] versus V [Volt] has a slope equal to R.

Explanation:

A resistor is said to be Ohmic if it obeys ohms law. In am Ohmic resistor, the resistance is constant regardless of the current passing through it. Graphically, an ohmic resistor as a linear relationship when its current and voltage relationship is presented graphically.

Consider the following four objects: a hoop, a flat disk, a solid sphere, and a hollow sphere. Each of the objects has mass M an

Mumz [18]

Answer:

The hoop

Explanation:

We need to define the moment of inertia of the different objects, that is,

DISK:

$I_{disk} = \frac{1}{2} mR^2$

HOOP:

$I_{hoop} = mR^2$

SOLID SPHERE:

$I_{ss} = \frac{2}{5}mR^2$

HOLLOW SPHERE

$I_{hs} = \frac{2}{3}mR^2$

If we have the same acceleration for a Torque applied, then

$mR^2>\frac{2}{3}mR^2>\frac{1}{2} mR^2>\frac{2}{5}mR^2$

$I_{hoop}>I_{hs} >I_{disk}>I_{ss}$

The greatest momement of inertia is for the hoop, therefore will require the largest torque to give the same acceleration
