Jenna is learning how to ice skate. she wants her mother to pull her along so that she has an acceleration of 0.76 m/s2. if jenna’s mass is 32.0 kg, with what force does her mother need to pull her? (neglect any resistance between the ice and jenna’s skates.)

Abucket full of water weights 4 kg and water well is 10m deep. a girl draws water from the well. it takes the girl 3 minutes to draw a bucket full of water from the well. what is the power of the girl?

Argon, neon, and xenon are examples of

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?
