4. Irene, Aditya, Valerie, and Lupita are in a dogsled race. Using the equations for Newton's second law, who would MOST LIKELY win if each dog pulls with a force of 50 N?
• Irene has 8 dogs and a sled with a total mass of 500 kg.
• Aditya has 6 dogs and a sled with a total mass of 400 kg.
• Valerie has 7 dogs and a sled with a total mass of 550 kg.
• Lupita has 10 dogs and a sled with a total mass of 600 kg. Saved at 10:07 AM PDT

Asample of a gaseous substance changes into liquid. this process is called (blank) and it takes place when heat is (blank) a gaseous system

A1200 kg car traveling north at 10 m/s is rear-ended by a 2000 kg truck traveling at 30 m/s. what is the total momentum before and after the collision?

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
