Answer:
46.45 m/s
Explanation:
Total momentum before jump = Total momentum after jump
11.7 * ( 36.7 + 45.2 ) = ( 36.7 * (-31.1) ) + ( 45.2 * v )
v*45.2 - 1141.37 = 958.23
v = 2099.6/45.2 = 46.45
Answer:
It is an open circuit as the current isn't flowing through the circuit as the wires aren't connected
Answer:
Vf=140 m/s
Vi=0
t=50s
Explanation:
1. Acceleration is called change of velocity.
2. a=Vf-Vi/t
a=140-0/50
a=140/50
a=2.8m/s^2
Answer:
=0.2093J
Explanation:
Heat required(Q) = mcø
= (10/1000)*4.186*(30-25)
= 0.2093J
Explanation:
some objects that are conduct :Metals conduct electricity, so if there is just the symbol of a metal, eg Mg(s), then it will conduct, even in the solid or liquid state. 2. Ionic compounds conduct when they are dissolved in water, or are melted.
what can it do ?:
A conductor is a material which electricity, heat or sound can flow through. An electrical conductor conducts electricity. ... This means that they make it very hard for electricity to flow through them. A material that stops electric current is called an insulator (electricity).
hope this helped! if not I'll answer again
