Answer:

series

Explanation:

In a series circuit all the components are attached to one branch, so that if one component fails, all the others stop working. In a parallel circuit, however, the components are wired in separate branches, so that even if one branch fails, the rest are not disrupted.

Series circuit.. If one bulb burns out in a series circuit, then this will break the circuit. This is because every device in a series circuit must work properly for the circuit to be complete. Unlike in a parallel circuit - where each light has its own circuit - so even if one bulb burns out, the remaining bulbs will still function.

You are in Paris, 60 m up in the Eiffel Tower. If you throw a euro downward at a velocity of 2.0 m/s, how long would it take the

kondor19780726 [428]

Answer:

t = 3.29 seconds

Explanation:

It is given that,

Height of the Eiffel tower is 60 m

Initial speed of a euro, u = 2 m/s

It will move under the action of gravity in the downward direction. Firstly, we can find the final velocity as follows :

$v^2-u^2=2ad\\\\v=\sqrt{u^2+2ad} \\\\v=\sqrt{(2)^2+2\times 9.81\times 60} \\\\v=34.36\ m/s$

Let t is the time taken by the euro to hit the ground. It can be calculated as :

$v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{34.36-2}{9.81}\\\\t=3.29\ s$

Hence, it will take 3.29 seconds to hit the ground.

Hoover Dam on the Colorado River is the highest dam in the United States at 221m, with a power output of 680 MW. The dam generat

DiKsa [7]

Answer:

The power in this flow is $9.56\times10^{8}\ W$

Explanation:

Given that,

Distance = 221 m

Power output = 680 MW

Height =150 m

Average flow rate = 650 m³/s

Suppose we need to calculate the power in this flow in watt

We need to calculate the pressure

Using formula of pressure

$Pressure=\rho g h$

Where, $\rho$ = density

h = height

g = acceleration due to gravity

Put the value into the formula

$Pressure=1000\times9.8\times150$

$Pressure=1470000\ Nm^2$

We need to calculate the power

Using formula of power

$P=Pressure\times flow\ rate$

Put the value into the formula

$P=1470000\times650$

$P=9.56\times10^{8}\ W$

Hence, The power in this flow is $9.56\times10^{8}\ W$

Describe how gps data are used in the study of certain animals

zheka24 [161]

GPS also known as Global positioning system is a satellite-based radio -navigation system used for many purposes, animal tracking being one of them.

In GPS tracking, a GPS tag is placed on the animal. This picks up signals from special satellites and the data is stored on-board the tag or transmitted to the user through a communication network.

These tags provide very accurate location estimations for animals. Thus it helps scientists and other wildlife observers with the accurate locations of animals and helps them in their studying and thesis work.

How could you reorganize Table 2-2 so that the data would be more useful?

velikii [3]

First, I would make a copy of Table 2-2 with some color of ink
that's visible, to replace the current one printed in invisible ink.

That change would immediately make the whole table more useful,
and I could go ahead and think about how to reorganize the data.
