During a 30 minutes period, a mass of 4.2 x10^7kg of air enters to turbine with aspeed 15m/s, calculate the kinetic energy of the air that enters the turbine in 30 minutes

Work = force × a. work b. energy c. distance d. momentum

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?

What are the necessary conditions for fusion?
