Answer:
Force
Explanation:
Force is a pull or push that causes An objects motion to change . When force is applied to an object , it either pushes the object to or pulls it from something thereby changing the motion of the object. A good example is the earth’s gravitational force. This force pulls or attracts a body to the center of the earth . Another example Is experienced when kicking a football from one part of a football field to another. The ball is kicked with force and this causes it to move from one place another .
To determine the distance (d) traveled by a body given its speed (S) and the time (t). Use the equation,
S = d / t ; d = S x t
Substituting the known values to the equation,
d = (4 m/s ) x (40 s) = 160 m
Thus, the person will travel 160 meters in 40 seconds.
Equation: -10 40/4^2
Explanation: I multiplied the -10, but idk if that' what you do cause I've never done this. So if you do do that it's -1000, but that is probably wrong. Sorry, I tried.
Answer:
The value is 
Explanation:
From the question we are told that
The voltage is 
The current is 
Generally the resistance value is mathematically represented as
=> 
=>
We have that the momentum p is given by the formula p=mv where m is the mass and v is the velocity. Since for A p=-14kgm/s and m=7, we have that the velocity is -14/7=-2m/s. Hence its speed is 2 m/s.
For b we have that p=15kgm/s and v=3m/s. Because m=p/v, we have m=3kg.
We also have that the momentum is conserved in this system. Hence, the net sum of the momentum of the 2 snowballs equals the momentum of the single giant ball. Hence, p(total)=p(combined)=-14+15=1kgm/s (momentum is a vector; the positive sign means that it tends to the positive direction).
