There is a elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, wjat is the potential energy that the wether vane has?

Solution :

Given :

Height of the tower , h = 45 m

Weight of the weather vane, mg = 190 N

So the potential energy possessed by the weather vane is given by

E = m x g x h

where, E is potential energy

           m is mass

           g is acceleration due to gravity (taken as 10 m/s2)

           h is height

Therefore,

E = m x g x h

E = (mg) x h

E = 190 x 45

E = 8550 J

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
