<span>A mechanical wave is created when a source of energy causes a vibration to travel through a medium 

And yeah lol 
A mechanical wave is a disturbance in matter that carries energy from one place to another :) 

This what you needed? </span>

Method and answer please.
Semenov [28]

Answer:

(a) 200.0628 N   ;   ( b) 4.08Kg

Explanation:

We know,

w = mg        [here w= weight , m= mass , g= gravity]

now,

gravity on earth (g) =9.807 m/s²

mass of the spanner (m)=?

weight of the spanner on earth(w) = 40N

                                              ⇒ w = 40N

                                              ⇒m g =40N

                                              ⇒m = (40/g) Kg

                                              ⇒m= (40/9.807)Kg

                                             ∴m=4.08Kg

∴mass of the spanner on earth = 4.08Kg

We know,

Mass is the amount of matter in an object . So mass will remain same both on earth and jupiter.

So,

(b)The mass of the spanner on jupiter =  4.08Kg

Now,

The mass of the spanner on jupitar (m) =  4.08Kg

Gravity on jupiter (g*) = 5.g              [5 times on earth]

                                   = 5 . (9.807)m/s²

                                   =49.035 m/s²

(a)    

∴weight of the spanner on jupitar(w*) = m g*

                                                            =(4.08 x 49.035) N

                                                            =200.0628 N

A charge Q acts on a point charge to create an electric field. Its strength, measured a distance of 40 cm away is 100 N/C. What
KIM [24]

Answer:

E_2=80N/C

Explanation:

From the question we are told that:

Initial Distance d_1=40cm=>0.4m

Initial Electric field strength E_1=100N/C

Final Distance d_2=20cm=>0.20m

Generally the equation for Electric field is mathematically given by.

 E=\frac{kq}{d^2}

 q=\frac{100*(0.4)^2}{K}

Substituting q for d=20cm

 E_2=\frac{k}{0.2}*\frac{100*(0.4)^2}{K}

 E_2=80N/C
