Explanation:
Mechanical energy (the sum of potential and kinetic energy) is constant:
ME = PE + KE
ME = PE + ½ mv²
PE = ME − ½ mv²
So the slope of the line is -½ of the mass.
Answer:
V= C√p/s
Explanation:
We are given that
Dimension of speed of sound
V = L T ^-1
Volume of gas = L³
Pressure P= M¹L^-1T^-2
Density =M¹L^-3
So
LT^-1 = C [M¹L^-1T^-2]^x [M¹L^-3]^y [L³]^z
Compare powers
We have
x+y=0
-x+3y+3z=1
-2x=-1
So x= 1/2 y= -1/2 z= 0
So finally we substitute in
V=cp^xp^y V^z
We have
V= C√p/s
It's mechanics
sometimes: Newton's motion
Answer:
In a collision, there is a collision force which endures for some amount of time to cause an impulse. This impulse acts upon the object to change its velocity and thus its momentum
