Answer:
a)3312 x 10⁴ J
b)I = 57.5 A
c)9200 W
Explanation:
Given that
P =4600 W
Time t= 2 h = 2 x 3600 s= 7200 s
We know that
1 W = 1 J/s
a)
Energy stored in the battery = P .t
=4600 x 7200 J
=3312 x 10⁴ J
b)
We know that power P given as
P = V .I
V=Voltage ,I =Current
4600 = 80 x I
I = 57.5 A
c)
The energy supplied = 4600 x 2 = 9200 W
<span>Weather satellites and weather stations are similar, because they both have the same purpose. They are used to help predict future weather as well as as current conditions. The satellites are viewing the weather from a distance at a large scope, but stations are using data they collect on earth to help with the same task.</span>
