Answer: 5.41 V
Explanation:in order to explain this result we have to use the Ohm law given by:
ΔV=R*I where R is the resistance which is equal R= ρ*L/A . ρ is the resistivity, L the length of the wire and A is the cross section. I is the current.
Then we have
ΔV=ρ*L*I/A= 1.68 * 10^-8 Ωm*93.4 m*72.5A/2.1* 10^-5 m^2=5.41 V
the answer is c: kilogram
explanation: The standard International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice.
Answer: a=-2.4525 m/s^2
d=s=190.3 m
Explanation:The only force that is stopping the car and causing deceleration is the frictional force Fr
Fr = 25% of weight
W=mg
W=1750*9.81
W=17167.5
Hence

Frictional force is negative as it acts in opposite direction
According to newton second law of motion
F=ma
hence


given
u= 110 km/h
u=110*1000/3600
u=30.55 m/s
to get t we know that final velocity v=0

Answer: I think the answer is D
Explanation: N/A
