Answer:
Explanation:
Given
mass of ball is m
initial velocity of ball is 
Final velocity of ball is
Impulse is the change in momentum of an object when an external force is applied for a given interval of time.
Initial momentum 
Final momentum 

<span>In an experiment, a researcher can make claims about causation if the independent variable changes because of changes made to the dependent variable. Causation works on cause and effect, so the changed independent variable is the cause and the changed dependent variable is the effect. In an experiment the independent variable is changed to determine the dependent variables value, so the two are directly related.</span>
Answer:

Explanation:
We are given that
Current=I=1.75 A
Resistance =R=55.4 ohm
Time=t=9.5 min=
1 min=60 s
We have to find the heat generated by the resistor.
We know that
Heat=E=
Using the formula
Heat,
Hence, the heat generated by the resistor =
Answer:
In my mind when I hear the word momentum it comes that it is the product of mass and velocity.
