A car has a mass of 1000 kg and accelerates at 2 m/s2. What net force is exerted on the car?
prisoha [69]

Answer:

1000N

Explanation:

Based on force=mass*acceleration, if the acceleration is constant at 2 metres per second squared, 1,000kg*2m/s^2=2,000N of force.

If the acceleration steadily increases to 2m/s^2 in 20 seconds, take the average which is 1m/s^2 therefore force=1,000N

Which of the following material offers the lowest resistivity?
Yuki888 [10]
Lower resistivity means higher conductivity: among these materials, the best conductor is silver, therefore it must be the material with lowest resistivity among those. We can also have a look at the value of resistivity of the different materials listed in the problem, to check our answer. The resistivities of the materials are the following:
Wood: 1.00\cdot 10^{3} \Omega \cdot m
Salt water: 2.00\cdot 10^{-1} \Omega \cdot m
Silver: 1.59\cdot 10^{-8} \Omega \cdot m
Lead: 2.20\cdot 10^{-7} \Omega \cdot m
<span>We see that the material with lowest resistivity among those is silver, therefore the correct answer is silver.</span>
