Your total expense would be 35$ because 25+10=35 and then since you are talking about money you add the money sign. Your answer would be 35$
Answer:
$26.91
Step-by-step explanation:
9.50 +13.93 =23.43
50.34 - 23.43 = 26.91
Answer:
yes
Step-by-step explanation:
I think sorry if I am wrong
Answer:
W1 = W2 = 50k Joules (assuming W1 and W2 have the same force constant, k)
W1 - W2 = 0
Step-by-step explanation:
Work done in stretching a spring is given by 1/2ke^2
Where, k is force constant and e is extension
e1 = 30cm - 20cm = 10cm
W1 = 1/2k(e1)^2 = 1/2×k×10^2 = 50k Joules
e2 = 40cm - 30cm = 10cm
W2 = 1/2k(e2)^2 = 1/2×k×10^2 = 50k Joules
W1 = W2 = 50k Joules provided W1 and W2 have equal force constant
Therefore, W1 - W2 = 0
36/4=9 48/3=16 so 9*16=144/2=72 so it is 72 square inches
