Want this question answered?
Velocity = Distance / Time= 6000m / 10s= 600 m/s= 1342.2 miles per hour= 22.369 miles per minute= 1166.3 knots= 1968.5 feet per second
3000m/s
v = u + at so 27 = 0 +a10 thus (27-0)/10 = a Acceleration = 2.7 m.s-2
Two equations are needed power = current x potential difference (voltage) and energy = power x time 720kJ = 720 000J 10 mins = 600s Power = 720 000 / 600 = 1200 Watts 1200 = I x 25000 Current, I = 0.048 A
You use the equation d = vit + 1/2at2, where d is distance or displacement, vi is initial velocity (0), t is time, and a is acceleration. d = (0)(10s) + (1/2)(9.8m/s2)(10s)2 = 0 + 490m = 490m The answer above does not take into account air friction or the possibility that the rock will hit the walls of the shaft and slow down due to that friction. Air friction will shorten the distance by perhaps 15% to 30% depending, among other things on the shape and mass of the rock, retardation due to hitting the shaft walls is unpredictable.
power=work/time work=forcexdistance therefore work=40x9.81x10 work=3924joule power=3924/10 power=392.4watts
ok i get this
First, calculate the work done. Work is equal to the force on an object multiplied by the distance the object was moved by that force. W = Fd Since the bag of cement weighs 100 N, the force required to move it at a constant velocity must equal 100 N (otherwise, it would accelerate). The distance is given as 20m. W=(100N)(20m)=2000 Nm or 2000 Joules Next, calculate the power. Power is defined as the work done per time, or work divided by time. P=W/t You have already calculated the work (2000 J), and the time is given as 10 seconds. P=2000J/10s=200 Watts
there are 7 tenths in 275 or 2.75 10s
60 W
Scientific notation or standard form
There are 8 10s in 85, with 5 left over.
Sadly, the phrase "10s to 76w longitude" is quite meaningless.-- As soon as you say "10s" or "10 south", that's the latitude.-- 10s/76w is the latitude and longitude of a point. The point isin central Peru, about 165 miles northeast of the center of Lima.

The Badger 9 is sold exclusively at The Home depot while the 10s in exclusively sold through Lowe's. These both have the same 3/4 HP power rating and warranty coverage as the Badger 5XP, which is sold in general plumbing stores.
