Answer:

Series circuit:

The voltage that is measured across the circuit is different.

The current measured in a series circuit remains the same at all points in the circuit.

Parallel circuit:

The current measured across each resistor varies

The voltage measured across a parallel circuit will remain the same

Explanation:

Series and parallel circuits behave differently when it comes to the circulation of current and the interaction with a potential difference.

In a series circuit, the resistances are connected end to end. As a result, the voltage that is measured across the circuit is different once resistance is encountered. However, the current measured in a series circuit remains the same at all points in the circuit.

A parallel circuit behaves in an exactly opposite manner to the series circuit. In a parallel circuit, the resistances are connected side by side. As a result of this, the current measured across each resistor varies as there are circuit branches through which electric current can flow into. On the other hand, the voltage measured across a parallel circuit will remain the same

Some hummingbirds beat their wings more than 50 times per second. A scientist is measuring the time it takes for a hummingbird t

Aliun [14]

Answer:

millisecond

Explanation:

Time is measured in seconds in the SI system. The scientist will measure the time it takes to complete one flap of the wings. In the SI system the use of prefix makes it easier to describe the value. It is as follows

$1\ ns=10^{-9}\ s$

$1\ \mu s=10^{-6}\ s$

$1\ ms=10^{-3}\ s$

$1\ cs=10^{-2}\ s$

Here, the wings flap so fast that the millisecond should be used.

Under constant pressure, the temperature of 2.43 mol of an ideal monatomic gas is raised 11.9 K. What are (a) the work W done by

const2013 [10]

Answer:

Explanation:

Given

no of moles $n=2.43$

Temperature raised $\Delta T=11.9 k$

Work done by gas

$W=\int_{V_1}^{V_2}PdV$

$W=P\Delta V$

$W=nR\Delta T$

$W=2.43\times 8.314\times 11.9$

$W=240.41 kJ$

(b)Energy Transferred as heat

$Q=nc_p\Delta T$

$c_p$ =specific heat at constant Pressure

$c_p$ for ideal Mono atomic gas is $\frac{5R}{2}$

$Q=2.43\times \frac{5R}{2}\times 11.9$

$Q=601.03 kJ$

(c)Change in Internal Energy

$\Delta U=Q-W$

$\Delta U=601.03-240.41=360.62 kJ$

(d)Change in average kinetic Energy $\Delta k$

$K.E._{avg}=\frac{3}{2} \times k\times T$

$\Delta K.E.=\frac{3}{2} \times k\times \Delta T$ ,where k=boltzmann constant

$\Delta K.E.=\frac{3}{2}\times 1.38\times 10^{-23}\times 11.9$

$\Delta K.E.=2.46\times 10^{-22} J$

Think about the way optical fibers are designed. why are the ends of the fibers glowing very brightly while the sides of the fib

Effectus [21]

Answer:

D. because the light is reflected back into the fiber along its sides

Explanation:

The fiber is constructed in a way that the light is bent/reflected/refracted toward the center core of glass. So, from the center core, there is a layer above it that has a different propagation than the core, and above that the same thing. To give you a real world visual example, if you look down in a pool of water, then stick a straight stick into it, you see that the straight stick appears to bend. That is what is happening to the light as it travels through a different medium (air to water). This same effect is incorporated in the fiber optic cable construction.
