What does v. p=mv mean
can someone

This is the formula for momentum. 

P stands for momentum.

m stands for mass.

v stands for velocity

Hope I helped! :)

The equation is the equation of momentum in physics. Where;
p is momentum in physics
m is mass
v is velocity
  The equation is basically
momentum=mass x velocity
  Momentum is a vector quantity, which means it has magnitude and direction. So in defining momentum, you can simply say momentum is the product of mass and velocity. Hope i helped. Have a nice day.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
