From what I understand, If a minor holds a learners permit, they can only drive as long as someone the age of 21 or older with a valid driver's license is accompanying in the passenger seat. Can they have a minor in the backseat as well? or is only the Adult allowed in the vehicle?Basically can a minor with a learners permit drive with an Adult over the age of 21, AND a minor at the same time, or is no on else allowed in the car.

Consider a Lear jet flying at a velocity of 250 m/s at an altitude of 10 km, where the density and temperature are 0.414 kg/m3 and 223 K, respectively. Consider also a one-fifth scale model of the Lear jet being tested in a wind tunnel in the laboratory. The pressure in the test section of the wind tunnel is 1 atm = 1.01x105 N/m2. Calculate the necessary velocity, temperature, and density of the airflow in the wind-tunnel test section such that the lift and drag coefficients are the same for the wind-tunnel model and the actual airplane in flight. (R=287 J/kg-K; Assume 'a' and 'p' are directly proportional to T12)

A square (10 mm 10 mm) silicon chip is insulated on one side and cooled on the opposite side by atmospheric air in parallel flow at u[infinity] = 20 m/s and T[infinity] = 24C. When in use, electrical power dissipation within the chip maintains a uniform heat flux at the cooled surface. If the chip temperature may not exceed 80C at any point on its surface, what is the maximum allowable power? What is the maximum allowable power if the chip is flush mounted in a substrate that provides for an unheated starting length of 20 mm

Pipe 2 has been inserted snugly into Pipe 1, but the holes for a connecting pin do not line up; there is a gap s. The user decides to apply either force P1 to Pipe 1 or force P2 to Pipe 2, whichever is smaller. Determine the following using the numerical properties in the box.(a) If only P1 is applied, find P1 (kips) required to close gap s; if a pin is then inserted and P1 removed, what are reaction forces RA and RB for this load case?(b) If only P2 is applied, find P2 (kips) required to close gap s; if a pin is inserted and P2 removed, what are reaction forces RA and RB for this load case?(c) What is the maximum shear stress in the pipes, for the loads in parts (a) and (b)?(d) If a temperature increase T is to be applied to the entire structure to close gap s (instead of applying forces P1 and P2), find the T required to close the gap. If a pin is inserted after the gap has closed, what are reaction forces RA and RB for this case?(e) Finally, if the structure (with pin inserted) then cools to the original ambient temperature, what are reaction forces RA and RB?
