the answer would be "screw and lever!", thats the answer because the middle is made into a rod of metal rapped in metal to screw into the cork, and the lever part is the two handles on the side to lift it out of the bottle.
The answer to this question would be: 1m/s
When you are walking to the north with 2m/s velocity, the stationary object(velocity=0m/s) will look like moving south at 2m/s velocity. That happens because the relative distance between you and the object is reduced by 2m/s in both conditions. In this question, the man seems like have 3m/s velocity. The real velocity should be:
3m/s - 2m/s = 1m/s
In my opinion I would say all of the above; because people's job depends on where they live or how their environment is. The way they travel is also affected because we can't travel by car through water and can't use a boat in land. Free time as well because people like to travel and or just stay at home depending on the weather which is part of earths features.
Answer:
26.17 V
Explanation:
In a alternator , an ac voltage is produced whose magnitude of voltage varies sinusoidally.
Maximum voltage induced = nBAω
where n is no of turns , B is magnetic field , A is area of the coil and ω is angular velocity .
Rate of rotation n = 1000rpm = 1000/60 rps = 16.67 rps
angular velocity ω = 2π n = 2π x 16.67 = 104.68 rad / s
Putting all values in the given equation above
Max voltage = 250 x .1 x .01 x 104.68
= 26.17 V
Answer:
An electrical cell is a device used to generate electricity, or to make chemical reactions by applying electricity.
