Answer:
 4375 N, 7875 N
Explanation:
since the body is equilibrium
total upward force = total downward force
w weight of the bridge = FL + FR 
when the car was introduced, 
total downward force = total upward force 
FL₁ + FR₁ = w + (m × acceleration due to gravity) with w = FL + FR 
then FL₁ + FR₁  = FL + FR + Mcg
FL₁ + FR₁  - FL - FR = Mcg
ΔFL + ΔFR = 1250 × 9.8 = 12250 N 
taken the left as the pivot point and using the principle of moment 
ΔFR × 14 m = 12250 N × 5 m + (ΔFL × 0 m) since the left is the pivot point.
ΔFR = 61250 / 14 = 4375 N
but 
ΔFL + ΔFR = 12250 N 
ΔFL = 12250 - 4375 = 7875 N

Using the kinematic equation below we can determine the distance traveled if t=2, a=7.4m/s^2.  First we must determine the final velocity:

Now we will determine the distance traveled:

Therefore, the drag racer traveled 81.83 meters in 2 seconds.
 
        
             
        
        
        
Answer:
The mass of the products and reactants are the same on both sides of the equation. 
The number of atoms of products and reactants are equal and hence it proves the law of conservation of mass.

Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. Stars are typically classified by their spectrum in what is known as the Morgan-Keenan or MK system.
