Answer:

D.) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.

Explanation:

mass of ball 1

m_1 = 140 grams

mass of ball 2

m_2 = 280 grams

now we know that if the momentum of two balls are same then we will have

P_1 = P_2

m_1v_1 = m_2 v_2

so we have

140 v_1 = 280 v_2

v_1 = 2 v_2

so velocity of light ball must be twice the velocity of heavy ball

so correct answer will be

D.) The baseball is thrown at 50 m/s and the softball is thrown at 25 m/s.

A spherical soap bubble with a surface-tension of 0.005 lbf/ft is expanded from a diameter of 0.5 in to 3.0 in. How much work, i
Sladkaya [172]

Answer:W = 1.23×10^-6BTU

Explanation: Work = Surface tension × (A1 - A2)

W= Surface tension × 3.142 ×(D1^2 - D2^2)

Where A1= Initial surface area

A2= final surface area

Given:

D1=0.5 inches , D2= 3 inches

D1= 0.5 × (1ft/12inches)

D1= 0.0417 ft

D2= 3 ×(1ft/12inches)

D2= 0.25ft

Surface tension = 0.005lb ft^-1

W = [(0.25)^2 - (0.0417)^2]

W = 954 ×10^6lbf ft × ( 1BTU/778lbf ft)

W = 1.23×10^-6BTU
