How tall is the table?

Mathematics
1 answer:
Solnce55 [7]2 years ago
6 0

Answer:

105cm

Step-by-step explanation:

Call the rat's height r, the cat's height c and the table height t.

The left part says that

(t + c) - (0 + r) = 120 = t + c - r

c - r = 120 - t

Right part says that (t + r) - (0 + c) = 90 = t + r - c

c - r = t - 90

120 - t = t - 90

2t = 210

t = 105

Suppose that 5 J of work is needed to stretch a spring from its natural length of 30 cm to a length of 39 cm.
vesna_86 [32]

Answer

given,

work = 5 J

spring stretch form 30 cm to 39 cm

W = \dfrac{1}{2}kx^2

x = 0.39 - 0.30 = 0.09 m

5 = \dfrac{1}{2}k\times 0.09^2

k = \dfrac{5\times 2}{0.09^2}

k = 1234.568 N/m

a) work when spring is stretched from  32 cm to 34 cm

x₂= 0.34 -0.30 = 0.04 m

x₁ = 0.32 - 0.30 = 0.02

W = \dfrac{1}{2}k(x_2^2-x_1^2)^2

W = \dfrac{1}{2}\times 1234.568 \times (0.04^2-0.02^2)^2

W = 0.741 J

b) F = k x

  25 = 1234.568 × x

     x = 0.0205 m

     x = 2.05 cm
