Can someone help me with number 1 and 2 plz!
GalinKa [24]

Answer:

1) 0 N

2) 8 N

Explanation:

The net force is the sum of all of the forces acting on the object.

For question 1, we can see that there is a force of 5 N acting to the right and 5 N acting to the left.  If we define the right to be positive and the left to be negative, then the net force equals:

Fnet = 5N - 5N = 0 N

Therefore, the net force in question 1 is 0 N.

For question 2, the process is very similar.  We want to find the sum of the forces acting on the object.  In this case, there are forces of 3 N and 5 N acting to the right.

Fnet = 3 N + 5 N = 8 N

Therefore, the net force in question 2 is 8 N.

Hope this helps!

If the solvent front is 68 mm and the ring front of an unknown is 48mm from the original spot, what is the rf value?
Nat2105 [25]

<u>Given:</u>

Distance of solvent front = 68 mm

Distance of unknown = 48 mm

<u>To determine:</u>

The rf value

<u>Explanation:</u>

The retention factor or the rf value is given by the ratio of distance traveled by the unknown to the distance traveled by the solvent front

RF = distance by unknown/distance by solvent

RF = 48/68 = 0.706

Ans: the RF value is 0.706

What is the effect of increasing pressure on the equilibrium? N2 + 3H2 ⇔ 2NH3 a) Equilibrium shifts in forward direction. b) Equ
koban [17]

Answer:

a) Equilibrium shifts in forward direction.

Explanation:

If pressure is increased, equilibrium shifts to the side with the fewer moles of gas.

There are 4 moles of gas in the reactants and 2 moles of gas in the products.

The equilibrium will shift in the forward direction towards the products.

Hope that helps.
