In both graphs, speed will be measured in meters/second.
In graph A, the object travelled a distance of 40 meters in 4 seconds
In graph B, the object is at rest for 5 seconds.
These are the correct answers
Answer: Force is 4 times lower.
Explanation:
F1=γ*m₁m₂/r²
r*2=2r
F2=γ*m₁m₂/4r₂
F1/F2=4
F2=F1/4
The formula for density is ρ=m/v where ρ is density, m is mass and v is volume.
I am not entirely sure but I think it is:
- Gravitation / Weight Force
- Drag force
- Lift force
Answer:
= 11.8 Ω
Explanation:
Using the equation;
RT = Rr [1 + α (T -Tr)
Where;
RT = Resistance of conductor at temperature T
Rr = Resistance of conductor at reference temperature Tr
α = Temperature coefficient of resistance at reference temperature Tr
Therefore;
RT = 10 Ω [ 1 + 0.004( 65-20)]
= 10 ( 1 + 0.004(45))
= 11.8 Ω
