A conducting material conducts or allows electricity to flow, while an insulator does not allow electricity to flow. For example think of a water pipe, if the pipe has a hole water can flow, on the other hand if it is just a solid rod, no water can flow through. I hope this helps.
Answer:
It remains the same.
Explanation:
During physical change, the mass, number of atoms and number of molecules will remain the same.
Answer:
<u>The radius of circle is 643 m.
</u>
Explanation:
The centripetal acceleration of the jet is
Where,
a is "centripetal acceleration"
V is "speed
"
r is "radius of the circle
"
Given values
,
Speed of the jet (v) = 700 km/h
(1 km = 1000 m; 1 h = 3600 sec. To convert km/h into m/sec, multiply the number by 5 and then divide it by 18.)
Speed of the jet (v)
V = 194.444 m/s
a = 6g's
Substitute the given values in the formula,
a = 643 m
The radius of circle is 643 m.
I think water vapour is the most important gas for understanding atmospheric processes.
correct me if i am wrong....... :)
Answer:
Explanation:
Taking moment of forces about the hinge ,
moment of weight of man = 800 x p where p is his distance of man from hinge , in clockwise direction .
moment of tension force in rope in anticlockwise direction
= 500 x 3
For rotational balancing
800 x p = 500 x 3
p = 1.875 m .
