120 volts for most home a phone charger can convert 120 volts ac to 5 volts dc
It'll certainly seem like it, because the water will get cold. But cold is not a thing. Heat is. What actually happens is that heat from the water flow into the ice (and melts it).
Question 1:
Looking for: "speed" (velocity: v)
Given: 112.0 meters (distance: d) 4.0 seconds (time: t)
Formula used: v=d/t
since velocity is equal to the distance (112m) divided by the time (4sec) you would have 112m/4s which is 28m/s. m/s is meters traveled per second traveling aka meters per second.
Question 2:
Looking for: average "speed" don't let the word average confuse you it is still velocity.
Given: 60km (distance: d) and 3.5 hours (time: t)
Formula required: v=d/t
Since velocity needs to be in the units of m/s first convert your time, which was provided in hours, to seconds.
3.5 hours 60 minutes per hour: 3.5 x 60= 210 minutes
210 minutes 60 seconds per minute: 210 x 60= 12600 seconds
also, kilometers needs to be converted to meters. The prefix kilo means 1000 so 1 kilometer = 1000 meters.
60 x 1000 = 60,000 meters
Plug the values into the equation required:
v=d/t
v= 60,000m / 12,600sec
v= 4.76 m/s
Well, there would have to major supports on every building that was tall even though we have very strong foundation the foundation doesn't do anything except no give us dirt as a floor.but a really strong structure to use is a triangle formation.
Hope this helped
The time taken to fill the vat can be found using the least common multiple [LCM]. Given that the first pipe fills the tank in 66 hours and the second one empty the tank in 1010 hours, the time taken to fill the tank will be:
LCM(66,1010)
=66*1010
=66,660 hours
the answer is:
66,660 hours
