Hi there!

$\:\mathsf\red{Your\:answer\:is\:B.\:(1)}$

<h2>Explantion :- </h2>

We know

Coefficient is the number or value which should be putten in front of the variable given.

Here,

'x' is the variable. Before <u>x</u>, there is no number mentioned. So the number would be 1.

The force acting between the particles is

$F=k \frac{Q_{1}Q_{2}}{r^2}$
Then

Which change will increase the speed of a sound wave traveling in a solid aluminum rod? changing the rod from a solid to a liqui

Pepsi [2]

Answer:

increasing the temperature of the rod

Explanation:

Sound wave is a longitudinal wave and its speed in a solid rod is given by the formula

$v = \sqrt{\frac{Y}{\rho}}$

here we know that

Y = young's modulus

$\rho$ = density of the medium

so as we increase the temperature of rod the density of the rod will decrease while the elasticity will remain same

So on increasing the temperature we can say that speed will increase due to decrease in the density

Kaya collects the data shown in the table.

Colt1911 [192]

<u>Answer;</u>

= 20 ohms

<u>Explanation;</u>

According to the Ohm's law, the current through a conductor is directly proportional to the potential difference if other environment conditions are kept constant.

Therefore; I α V

Hence; V = IR, where R is the constant, called the resistance

Therefore; R = V/I

R = 6.0 /0.3

<u> = 20 Ohms</u>

Two ice skaters, Lilly and John, face each other while at rest, and then push against each other's hands. The mass of John is tw

seropon [69]

Answer:

Lilly's speed is two times John's speed.

Explanation:

m = Mass

a = Acceleration

t = Time taken

u = Initial velocity

v = Final velocity

The force they apply on each other will be equal

$F=ma\\\Rightarrow a_l=\frac{F}{m_l}$

$F=ma\\\Rightarrow a_j=\frac{F}{2m_l}\\\Rightarrow a_j=\frac{1}{2}a_l$

$v=u+at\\\Rightarrow v_l=0+\frac{F}{m_l}\times t\\\Rightarrow v_l=a_lt$

$v=u+at\\\Rightarrow v_l=0+\frac{F}{2m_l}\times t\\\Rightarrow v_j=\frac{1}{2}a_lt\\\Rightarrow v_j=\frac{1}{2}v_l\\\Rightarrow v_l=2v_j$

Hence, Lilly's speed is two times John's speed.
