In terms of the air flow around an airplane wing, it is true that that underneath the wing:

Which of the following is an acceptable unit for density?

You are called to the emergent cesarean section of a full-term neonate due to placental abruption. The neonate required resuscitation in the delivery room. Apgars were 1 at 1 minute of life, 3 at 5 minutes of life, and 4 at 10 minutes of life.  Upon admission to the NICU, the neonate is lethargic with decreased activity, hypotonic, weak suck, weak Moro, constricted pupils (miosis), and bradycardia. The classification of HIE based on the Sarnat scale for this baby would be

If five light bulbs are connected in series to an energy source and one of them burns out, the others:

Use the circuit below to answer the following questions.  (7 marks) (a) What is the potential difference across R1? (b) If 10 A flows out of the battery, what is the current through R1? (c) What is the resistance of R1? (d) What is the resistance of the 7 V load?

If a car accelerates from 15 m/s to 25 m/s, what amount of work is done if the car has a mass of 800kg?

Electrical energy is supplied at the rate of 15 W for a time period of 5 hours to a light bulb that is rated as 75% efficiency. How much light energy is radiated by the bulb? (remember, there are 3600 s in 1 h)

Explain (with calculations) why a person with a weight of 500 N gets punctured when resting on a single nail, but remains unharmed when lying on a bed of nails.  Let the area of one nail be 0.00 005 m² and use a bed of about 2000 nails.  (5 marks)

When area doubles for a constant applied force, the pressure:

If two 100 Ω resistors are placed in series, their total resistance is:
