Answer:
Water can carry electricity
Explanation:
While pure water does not conduct electricity, ionized water does. It is common that water is ionized than is pure, unless it is purified. The dissolved ions in the water are what makes the water conduct electricity. Handling electric equipment with wet hands may lead to electrocution.
<span>You can start with the equations you know
a=v^2/r = (2pi*r/T)^2/r = 4pi^2r/T^2
Radius of earth (R) = 6378.1 km
Time in one day (T) = 86400 seconds
Latitude = 44.4 degrees
If you draw a circle and have the radius going out at a 44.4 degree angle above the center you can then find the r.
r=Rcos(44.4)
r=6378.1cos(44.4)
r= 4556.978198 km or 4556978 m
Now you can plug this value into the acceleration equation from above...
a= 1.8*10^8/7.47*10^9
a= .0241 m/s^2 </span>
Answer:
Why do I keep getting spam calls? Experts credit the ascendance of spam phone calls to fundamental problems with caller ID, a phone system where anyone can operate as a carrier, the inability to detect bad callers, and a number of bad actors exploiting those flaws to drive billions of calls to American phones.
Explanation:
Answer:
power=400Watt
Explanation:
work done =12kJ=12×10³=12000j
time taken=30s
power=?
as we know that
power=work done/time taken
power=12000J/30s
power=400Watt
i hope this will help you :)
