Answer:

B. The circuit would have less resistance.

Explanation:

When the lightbulb is replaced in the circuit by a wire, the circuit will have less resistance.

Resistance is the the opposition to the flow of current within a circuit. Both a light bulb and wire are two examples of resistors in a circuit.

A wire has a low value of resistance compared to the bulb.
This is why the overall resistance will reduce when a light bulb is replaced with a wire.

The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.

<h3>What is a magnetic field?</h3>

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

I is the current = 6.50 A

B is the magnetic field=f 2.71 X 10⁻⁵ T

The force on the wire is;

$\rm F= BIL \\\\\ F=2.71 \times 10^{-5} \ T \times 6.50 \ A \times 1.50 \ m \\\\\ F=0.000264225 \ N$

Hence, the force on one of the wires will be 0.000264 N.

The volume of a cantaloupe is approximated by Upper V equals four thirds pi font size decreased by 5 r cubedV= 4 3π r3. The radi

Answer:

68.445 cm³/s

Explanation:

Given:

Volume, V = $\frac{4}{3}\pi r^3$

radius = 5.85 cm

Growth rate of radius = 0.5 cm/week

now

differentiating the volume with respect to time 't', we get:

$\frac{dV}{dt}=\frac{d(\frac{4}{3}\pi r^3)}{dt}$

$\frac{dV}{dt}=(\frac{4}{3}\pi )3r^2\frac{dr}{dt}$

now, substituting the value of r (i.e at r = 5.85cm) in the above equation, we get:

$\frac{dV}{dt}=4\pi 5.85^2\times 0.5$

$\frac{dV}{dt}=68.445cm^3/s$

hence, the rate of change of volume at r = 5.85cm is 68.445 cm³/s
