riadik2000 [5.3K]

Answer:

(a) have greater resistance

Explanation:

There is an simple explaination to understand the resistance through a graph. THE HIGHER THE SLOPE OF THE LINE, THE LOWER THE RESISTANCE OF THE RESISTOR.

Remember that and you can do all of the related exercises.

The general electron configuration for atoms of the halogen group is

m_a_m_a [10]

Answer:

$ns^2np^5$

Explanation:

Halogen group:This group contains Cl,F,Br and I

There are 7 electrons in the outermost shell of each element of halogen family.

Each element of this family required one electron to fill their complete outermost shell.

We know that

$F=9=1s^22s^22p^5$

Cl=17= $1s^22s^22p^63s^23p^5$

Therefore, the general configuration for atoms of the halogen group is given by

$ns^2np^5$

A sound wave produced by a chime 515 m away is heard 1.50 s later. What is the speed of the sound in the air?

aliina [53]

Answer:

the speed of the sound in the air is 343.3 m/s

Explanation:

The computation of the speed of the sound in the air is shown below:

As we know that

Speed = Distance ÷ time

So, here speed be 515 m

And, the time is 1.50 seconds

So, the speed of the sound is

= 515 m ÷ 1.50 seconds

= 343.3 m/s

hence, the speed of the sound in the air is 343.3 m/s

A continuous length of wire is made into 10 coaxial loops, located in the plane of this page. Each loop has a cross sectional ar

AleksandrR [38]

Answer:

e = 10 V

Explanation:

given,

number of the coaxial loops = 10

Cross sectional area = 0.5 m²

magnitude of magnetic field =

B = 3 T + (2 T/s)*t.

B = ( 3+ 2 t ) T

induced potential difference = ?

At time = 2 s

we know,

induced emf

$e = - N\dfrac{d\phi}{dt}$

∅ = B . A

$e = - N\dfrac{d(BA)}{dt}$

$e = - NA\dfrac{dB}{dt}$

$e = - 10 \times 0.5 \times \dfrac{d}{dt}(3 + 2 t)$

$e = - 10 \times 0.5 \times 2$

e = -10 V

magnitude of induced emf

|e| = |-10 V|

e = 10 V

the induced potential difference in the loop = e = 10 V
