A rocket motor is manufactured by bonding together two types of propellants, an igniter and a sustainer. The shear strength of the bond is thought to be a linear function of the age ofthe propellant when the motor is cast. Twenty observations are shown in the following table.Observation Strength.Age(weeks)Observation Strength AgeNumber(psi)Number(psi)(weeks)125856.5112210.51752367.913.3I122664.27.5232612.5131789.82842287.718141763.7252217.5115151775.3272188.720.8162175.21947.2071.323172346.75151818.324.4182063.5261794,729.3192424.4los101688.1530.4202409.557.82) A rocket motor is manufactured by bonding together two types of propellants, an igniter and a sustainer.

.... At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. Wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. The cyclic nature of wind and moving sand determines the shape and location of large dunes. At a test site, the prevailing direction of the wind did not change noticeably. However, the velocity did change. Sixty-two wind speed readings gave an average velocity of x = 1075 cm/sec.

. At wind speeds above 1000 cm/sec, significant sand–moving events begin to occur. Wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. The cyclic nature of wind and moving sand determines the shape and location of large dunes. At a test site, the prevailing direction of the wind did not change noticeably. However, the velocity did change. 75 wind speed readings gave an average velocity of x =1045 cm/sec.
