Answer:

Into the page (Answer B)

Explanation:

Recall that the magnetic field that is created around a current conducting wire follows the right hand rule, where the direction of your fingers point in the direction of the magnetic field vectors when your thumb points in the direction of the current flow.

Use this to see that as you place the thumb of your right hand on the page pointing to the right (direction of the current in the wire). As you do so, you find the four fingers of your right hand entering the paper.

Write a balanced equation for the decomposition of ammonium nitrate to form molecular nitrogen, molecular oxygen, and water. Exp
VARVARA [1.3K]

The unbalanced reaction is

<em>a</em> NH₄NO₃   ⇒   <em>b</em> N₂ + <em>c</em> O₂ + <em>d</em> H₂O

where <em>a</em>, <em>b</em>, <em>c</em>, and <em>d</em> are unknown constants.

Count how many times each element appears on either side of the reaction.

• reactants:

N = 2<em>a</em>, H = 4<em>a</em>, O = 3<em>a</em>

• products

N = 2<em>b</em>, O = 2<em>c</em> + <em>d</em>, H = 2<em>d</em>

<em />

Now we solve the system of equations,

2<em>a</em> = 2<em>b</em> … … … [1]

4<em>a</em> = 2<em>d</em> … … … [2]

3<em>a</em> = 2<em>c</em> + <em>d</em> … … … [3]

<em />

From [1] we immediately have

<em>a</em> = <em>b</em>

In [2], we get

2<em>a</em> = <em>d</em>

and substituting for <em>d</em> in [3] gives

3<em>a</em> = 2<em>c</em> + 2<em>a</em>

<em>a</em> = 2<em>c</em>

<em />

Let <em>c</em> = 1; then

• <em>a</em> = 2×1 = 2

• <em>b</em> = 2

• <em>d</em> = 2×2 = 4

So, the balanced reaction is

2 NH₄NO₃   ⇒   2 N₂ + O₂ + 4 H₂O

A factory worker moves a 21.0 kg crate a distance of 4.50 m along a level floor at constant velocity by pushing horizontally on
Alex_Xolod [135]

Answer:

61.803 Newtons

Explanation:

m = Mass of crate = 21 kg

\mu = Coefficient of kinetic friction between the crate and the floor = 0.3

g = Acceleration due to gravity = 9.81 m/s²

Force

F=\mu mg

\\\Rightarrow F=0.3\times 21\times 9.81

\\\Rightarrow F=61.803\ N

So, the magnitude of force must the worker apply is 61.803 Newtons
