What is the net force on this object? Small box with dot in the middle. Arrows originate at dot. Arrow up and Arrow down are sam

e length. Arrow up labeled F sub norm equals 20 N and Arrow down labeled F sub grav equals 20 N. Arrow to the right is longer than arrow to the left. Arrow to the right is labeled F sub app equals 22 N and arrow to the left is labeled F sub frict equals 14 N. 0 newtons 8 newtons 22 newtons 36 newtons

Only 2 forces are out of balance - the 22N and the 14N 
So the resultant force is 22-14 = 8N.

Answer:

The net force is 8N.

Step-by-step explanation:

Consider the provided information.

Two forces cancel each other if they are in opposite direction and the forces are equal, the net force is zero in this case.

Now consider the figure 1:

Here, vertical forces (up and down) cancel each other and horizontal forces do not cancel each other, thus the force is unbalanced.

Calculate the net force as shown:

F_{net} = F_g + F_n + F_f + F_a

Substitute F_g=-20, F_n=20, F_f =-14, F_a=22 in above  formula.

F_{net}= -20 + 20 -14 + 22 = 8 N

Hence, the net force is 8N.

Can you help me? <br><br> 4+3(x+5)=5x-7
PSYCHO15rus [73]

Answer:

13

Step-by-step explanation:

4 + 3(x + 5)=5 x - 7

3x + 19=5x - 7

3x + 19 - 19=5x - 7 - 19

3x =5x - 26

3x - 5x=5x - 26 - 5x

-2= -26

-2x/-2 = -26/-2

x= 13

It might be wrong. I may have made a mistake with typing sorry.

Hope this helps a bit.

Point D(-3.5) is a vertex of triangle DEF.After a rotation of the triangle about the origin, D' is located at (3,-5).Which of th
Nimfa-mama [501]
<h3>Answer: 180 degrees</h3>

note: it doesn't matter if its clockwise or counterclockwise when it comes to 180 degree rotations.

========================================

Explanation:

The rule for 180 degree rotations is

(x,y) ---> (-x, -y)

So the x and y coordinates flip in sign from positive to negative, or vice versa.

Point D ' (-3, 5) rotates to D ' (3, -5) following this rule

-----------------

A further detailed break down might look like this

x = -3 becomes -x = -(-3) = 3

y = 5 becomes -y = -5

(-3, 5) ----> (3, -5)

Which expressions are equivalent to -2(5x-1)+7(5x-1)-3(-5x+1)
blondinia [14]

Answer:

x=1/5

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's go back to the given question

-2(5x-1)+7(5x-1)-3(-5x+1)

We can actually equate the equation to zero

Let's solve

-10x+2+35x-7+15x-3=0

Let's collect like terms

-10x+35x+15x=-2+7+3

40x=8

Let's make x the subject of formula by dividing both sides by 40

x=1/5

So the final answer is 1/5
