Four compasses are placed around a wire, as shown. the wire is then connected to a battery so that a current flows down the wire. how will the compasses point once the current is flowing?

the part of the wave he is travelling on is the crest

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
