Answer:
60 000 N
Explanation:
1 pa = 1 N/m^2
you have 300 000 of these   = 300 000 N /m^2 
     but only an area of .2 m^2 
                     300 000 N / m^2  * .2 m^2 = 60 000 N
 
        
             
        
        
        
Answer:
m≈501.57 g 
Explanation:
The density formula is:
d=m/v
Let’s rearrange the formula for m. m is being divided by v. The inverse of division is multiplication, so multiply both aides by v. 
d*v= m/v*v 
d*v=m
The mass can be found by multiply the density and the volume. 
m=d*v 
The density is 1.06 grams per milliliter and the volume is 473.176 milliliters. 
d= 1.06 g/mL
v= 473.176 mL 
Substitute the values into the formula. 
m= 1.06 g/mL * 473.176 mL 
Multiply. When multiplying, the mL will cancel out. 
m= 501.56656 g 
Let’s round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7 in the hundredth place. 
m ≈501.57 g 
The mass is about 501.57 grams.
