An ice skater with a mass of 50 kilograms pushes another skater (with a mass of 40 kilograms) with a force of 25 Newtons. How much acceleration does the 50-kg skater have? Question 7 options: 0.625ms2 0, because only the 40-kg skater has a force on them 2ms2 0.5 ms2

Asher cycles 12 miles in 16 hours. what is his speed?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Exercise 2. find the wavelength of a photon emitted when an electron jumps from the n = 3 energy level down to the n = 2 energy level. where is this photon in the electromagnetic spectrum?
