The force acting on his feet.
Answer:
The velocity is 
Explanation:
From the question we are told that
The mass of the bullet is 
The initial speed of the bullet is 
The mass of the target is 
The initial velocity of target is 
The final velocity of the bullet is is 
Generally according to the law of momentum conservation we have that
=> 
=>
Answer:
Option D. Weight varies with location, but mass does not.
Explanation:
To know which option is correct, it is important that we have a background knowledge of mass and weight.
A brief summary of the difference between mass and weight is given below:
1. Mass is the quantity of matter present in an object while weight is the gravitational pull on an object.
2. The SI unit of mass is kilogram Kg) while that of weight is Newton (N)
3. Mass is constant while weight varies by location.
4. Mass can measured using a chemical balance or beam balance while weight can be measured using a lever or spring balance.
With the above information, we can see that mass of an object is always but the weight varies by location.
Earth quakes are commonly found along fault lines or tectonic plates.
Hope this helped :-) <span />
