Answer:

All matter contained electrons

Explanation:

The discovery and characterization of cathode ray suggested that it was a subatomic particle and cathode ray ( electron) was the first discovered. It immensely became the strong explanatory tool for chemical bond. This can be attributed to  the the ease with which electron move from one atom to the other.

the weight of an object on earth is 350 newtons. on mars the same object would weigh 134 newtons. what is the acceleration due t
Eddi Din [679]
Mass will remain constant on both planet, let mass of the object be "m".
let x be the <span>acceleration due to gravity on the surface of mars.
Weight of object on earth = m *g , where g is </span><span>acceleration due to gravity on the surface of earth
</span>⇒350 =  m *  9.8
⇒m = 350  /  9.8                        .............................equation(1)
Weight of object on mars = m * x , where x is acceleration due to gravity on the surface of mars
134  =   m   *  x                           .............................equation(2)
putting the value of m from equation (1) in equation(2) , we get,
x     =   (134  *  9.8) / 350
⇒  x   =   3.572 m/s²

In the process of changing a flat tire, a motorist uses a hydraulic jack. She begins by applying a force of 58 N to the input pi
AfilCa [17]

Answer:

The correct answer is "3899.92 N".

Explanation:

The given values are:

Force,

F_{app}=58 N

Ratio,

\frac{R_2}{R_1}=8.2

As we know,

Area, A=\pi r^2

or,

⇒  \frac{F_2}{F_1} =\frac{A_2}{A_1}

On substituting the value of "A", we get

⇒  \frac{F_2}{F_1} =\frac{\pi r_2^2}{\pi r_1^2}

⇒  \frac{F_2}{F_1} =\frac{r_2^2}{r_1^2}

On applying cross-multiplication, we get

⇒  F_2=F_1\times (\frac{r_2}{r_1} )^2

On substituting the given values, we get

⇒       =58\times (8.2)^2

⇒       =58\times 67.2

⇒       =3899.92 \ N
