yep mom and anonymous are 100% correct, thank you both.
i need help with this question Kai has a red bucket, a yellow bucket, and a green bucket. The red bucket holds twice as much water as the green bucket. The yellow bucket holds 8 quarts. If the three buckets hold 14 gallons in all, how many gallons does the
so would it be D then?
how should i consider the flow of water 500 g / minute and the area of the collector
from eg 2 you get 3y=13-2x you should subsitute it i eq 1 4x-(13-2x)=11 4x-13+2x=11 6x-13=11 6x=24 divid the eq by 6 we get x=4 the put x=4 in 3y=13-2x 3y = 13 -2*4 3y=5 y =5/3
F=85*cos20 N work=fd= 85*cos20*30 work =2,4 kNm
.x(x-3)=4 means that x=4 and x-3=4 Is that right? x^2-3x-4=0 (x-4)(x+1)=0 x1=4 and x2=-1 so if you put x = 4 then x-3 can't be equell to 4
write the q again
v = v0 + a*t a= (v-v0)/t a=(7-4)/3 a=1 cm/min^2 SI units m/s 4 cm/min = 0,04/60=6,7 10^-4 m/s 7 cm/min = 0,001167 a=5*10^-4/180 a=2,76 *10^-6 m/s
angular momentum of earth = Ie*ùe Putting ùe = 2ð/T = 2ð/(24*60*60) = 7.27*10^-5 If we assume average density of earth = 5500 kg/m³, and R = 6400 km, Ie = 8ðñeR^5 / 15 (formula for moment of inertia (MOI) of sphere with density ñe and radius R)
a) tan 110 degrees = tan 110-180= tan-70 b)sin 350 degrees = sin 350-360 = sin-10 degrees
I just found the following: I didn't find any time tables I still need help Regards Solar radiation on Earth: As the Sun's energy spreads through space its spectral characteristics do not change because space contains almost no interfering matter. However
i agree with you but is the result correct, my english is'nt ok i know i forgot the units, but sure it is joule
ok but what is solar flux and should i assume that time is 24 hours?
Epot=mgh = (70)(9.81)(3)=2060,1 Ek1 =(0.5)(70)(14.30)^2= 7157,15 Ek2 =(0.5)(70)(15.60)^2=8517,6 total energy= (Epot+Ek1)- Ek2 =9217,25-8517,6 =699,65
