Answer:
Available usage time for the computer = 10.185 hrs
Explanation:
for the dryer;
I = 15 A, V=240 V , t= 55min,
convert time from min to sec. t = 55*60 =3300 sec
Energy = IVt
Energy = 15*240*3300
Energy = 11,880,000 J
=11,800 KJ
using the energy for the clothes dryer to calculate for the time spent on the computer,
Energy = IVt
for the computer;
I = 2.7A V=120V , t=?
t=36,666.7sec
convert this value to hour by dividing by 3600
Answer:
Force,
Explanation:
Given that,
A potential energy function for a system in which a two-dimensional force acts is of the form of :
We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :
So, the force acting at the point (x,y) is . Hence, this is the required solution.
