Well it takes twice the amount of Y as it does X to make XY. Therefore it would take 2*43 or 86 grams of X

$2.31531\times 10^{-16}\ N$

Explanation:

When it comes to charges, the charges which are alike repel each other and the charges which are different will attract each other.

Here, there is a proton and electron which are different particles hence, they will attract each other.

$q_1=q_2$ = Charge of electron and proton = $1.6\times 10^{-19}\ C$

r = Distance between them = 997 nm

k = Coulomb constant = $8.99\times 10^{9}\ Nm^2/C^2$

Force is given by

$F=\dfrac{kq_1q_2}{r^2}\\\Rightarrow F=\dfrac{8.99\times 10^9\times 1.6\times 10^{-19}\times 1.6\times 10^{-19}}{(997\times 10^{-9})^2}\\\Rightarrow F=2.31531\times 10^{-16}\ N$

The force of attraction between the particles will be $2.31531\times 10^{-16}\ N$

A sled of mass 80 kg starts from rest and slides down an 18° incline 90 m long. It then travels for 20 m horizontally before sta

yaroslaw [1]

Answer:

net work done by friction = - 2205 J

Explanation:

given,

mass of sled = 80 kg

slide down at an angle of 18°

length = 90 m

travel horizontally = 20 m before starting back up a 16° incline.

net work = ?

$h_i = initial\ height$

$h_i = L_i Sin 18^0$

$h_i = 90 sin 18^0$

$h_i = 27.81\ m$

$h_f = Final\ height$

$h_f = L_f Sin 16^0$

$h_f = 90 sin 16^0$

$h_f =24.81\ m$

net work done by friction = change in potential energy

= mg (h_f - h_i)

= (75) (9.8) (- 27.81 + 24.81)

net work done by friction = - 2205 J

How far does a plane fly in 10.0 s while its velocity is changing from 175 m/s to 105 m/s at a uniform rate of

gizmo_the_mogwai [7]

Answer:

1400 m

Explanation:

Given:

v₀ = 175 m/s

v = 105 m/s

t = 10.0 s

Find: Δx

Δx = ½ (v + v₀) t

Δx = ½ (105 m/s + 175 m/s) (10.0 s)

Δx = 1400 m
