<span>This would be an isotropic object. Having isotropy means that, in every direction that the object could be measured, a similar (or the same) value or measure would be reached. This allows an object to be easier to shape and makes it easier to understand and predict the object's behavior under different circumstances.</span>

why does the value of capacitance of a capacitor increases in parallel combination but not in series??
NikAS [45]
It is easiest to consider problems like this by thinking exclusively about parallel plate capacitors for which C \equiv \frac{Q}{V} =\kappa \epsilon_0 \frac{A}{d} where Q is the charge separated (+Q on one plate, -Q on the other), V is the voltage difference between the plates, A is the area of each plate, and d is the separation between the plates.

When capacitors are connected in parallel, the voltage across each capacitor is the same. But with two capacitors, it will require more charge to reach the voltage V than it would with just one capacitor. In fact, if capacitor 1 requires charge

Two concentric current loops lie in the same plane. The smaller loop has a radius of 3.8 cm and a current of 12 A . The bigger l
Stolb23 [73]

Answer:

R_2=6.33cm

Explanation:

The equation for the magnetic field at the center of a circular loop is:

B=\frac{\mu_0I}{2R}

If we name the smaller loop as 1 and the bigger loop as 2 and we impose the same magnitude of the magnetic field at their center, we have:

B_2=B_1

\frac{\mu_0I_2}{2R_2}=\frac{\mu_0I_1}{2R_1}

\frac{I_2}{R_2}=\frac{I_1}{R_1}

R_2=\frac{I_2}{I_1}R_1

Which for our values means:

R_2=\frac{I_2}{I_1}R_1=\frac{(20A)}{(12A)}(3.8cm)=6.33cm

(Notice that we don't need to convert cm to m, we get our result in cm).

how much work www does the motor do on the platform during this process? enter your answer in joules to four significant figures
soldi70 [24.7K]

The motor in the platform works for W=1885J during this process.

<h3>What is joules?</h3>

The amount of energy expended when a force of one newton is applied across a displacement of one meter is known as a joule. A joule is equal to one watt of electricity emitted or lost over the course of one second. The British thermal unit (Btu) is sometimes used to express energy. the work- or energy-measurement unit derived from the SI. The energy required to accelerate a body with a mass of one kilogram over a distance of one meter using one newton of force is equal to one joule. Additionally, one joule is equal to one watt-second.

<h3>What is joules formula?</h3>

The energy required to exert one newton of force through one meter is measured in joules. For instance, the energy required to lift a one-kilogram object one meter is given by E = Fd = (ma)d = mgd = (1 kg)(9.8m/s2)(1 m) = 9.8 kg m/s2 = 9.8 joules.
