Answer: An applied force of 50 N is used to accelerate an object to the right across. A 5-kg object is sliding to the right and encountering a friction force that slows it down. Explanation: m=1000 kg and a=3m/s2 . hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N

Answer:
Gravity explains this.
Explanation:
Weights and mass are different terms .
Weight is defined as the force exerting on the surface due to the mass and gravity of acceleration.
Here mass is related to the density of the body. So as the density would be same mass woulnt vary.
Whereas the Gravity changes due to the property of the planet.
Gravity is different for different planets and hence moon and earth have two different values.
So the mass i.e density remains same on both planets but the g value always changes hence weight is different.
B D and E. C isn't the answer because it is stopped.
That's because the first and last carbon atoms cannot be branched to form an isomer . Therefore only the three middle carbon atoms can form isomers.
