A force of 100 newtons is applied to a box at an angle of 36º with the horizontal. If the mass of the box is 25 kilograms, what
notka56 [123]

Answer:

a_x=4.944m/s^2

Explanation:

Hello,

Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

F=ma

Nevertheless, since we've got a angled force, it becomes:

F=macos\theta

In this case, cos\theta accounts for the formed angle, so the horizontal acceleration turns out into:

a_x=\frac{F}{mcos\theta}=\frac{100kg*\frac{m}{s^2} }{25kgcos(36^0)}=4.944m/s^2

Best regads.

Removing one electron from an atom results in the formation of an Question 7 options: ion with a 1- charge. ion with a 7+ charge
olga nikolaevna [1]

I believe it is an ion with a 1+ charge. If you remove an electron from an atom it will have a positive charge. But if you add electrons it will be a negative charge. Hope I helped!

The distance between the centers of the two oxygen atoms in an oxygen molecule is 1.21 x 10-8 cm. What is this distance in inche
Sergio [31]

Answer:

d=4.75\times 10^{-9}\ \text{inches}

Explanation:

Given that,

The distance between the centers of the two oxygen atoms in an oxygen molecule is 1.21\times 10^{-8}\ cm.

We need to convert this distance in inches.

We know that,

1 cm = 0.393 inches

We can solve it as follows :

1.21\times 10^{-8}\ cm=0.393\times 1.21\times 10^{-8}\\\\=4.75\times 10^{-9}\ \text{inches}

So, the distance between the centers of the two oxygen atoms is 4.75\times 10^{-9}\ \text{inches}.
