Answer:
30.7m
Explanation:
You can use the following equation:
ρ = R * 
Where ρ is the resistivity, R is the resistance, S is the Cross-sectional Area and l is the length of the wire.
We issolate l in the equation and solve with the data we have:
l = R * 
= 3.25 Ω * 
l = 30.7m
Answer:
If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.
Explanation:
Answer:
2.52N
Explanation:
according to law of moments ,
F1L1=F2L2 ,where the forces are in equilibrium .
0.85(44.5)= 15F2
that is , taking their distances from 50cm point
37 .825=15F2
37.825÷15= F2
2.52N = F2
Explanation:
Evaporation requires energy in order to break up intermolecular forces and excite water molecules (fast-moving gas molecules vs. slower moving liquid molecules). Therefore when the water in the wet clothes evaporates, it is drawing away some heat from your body (the surroundings
