Answer:
The concept of conservation of momentum is applied in the particular case of collisions.
The general equation ig given by,

Where,

The crash occurs at an intersection so we must separate the two speeds by their respective vector: x, y.
In the case of the X axis, we have that the body
has a speed = 0, this because it is not the direction in which it travels, therefore

The same analysis must be given for the particular case in the Y direction, where the mass body
does not act with its velocity here, therefore:

We have the two components of a velocity vector given by

Get the magnitude,


With a direction given by

Answer:
option B
Explanation:
given,
Force exerted by the hydraulic jack piston = F₁ = 250 N
diameter of piston, d₁ = 0.02 m
r₁ = 0.01 m
diameter of second piston, d₂ = 0.15 m
r₂ = 0.075 m
mass of the jack to lift = ?
now,




F₂ = 14062.5 N
F = m g


m = 1435 Kg
hence, the correct answer is option B
-3 m/s
---------
per min
oh I think 8m/s to 3m/s to 0m/s
idk probably -0.08
Answer:
Mass
Explanation:
Inertia is essentially an object's tendency to stay in motion or at rest unless it is forced to do otherwise (pun intended). It only makes sense to me that mass would best quantify an object's inertia, because an object with more mass would be harder to move and/or stop from moving.
Explanation:
A) The distance between the two successive compressions (or rarefactions) is actually called the wavelength of the longitudinal waves.
B) Wavelengths of longitudinal and transverse waves are comparable in the fact that in a transverse wave, the particles move perpendicular to the direction the wave travels whereas in a longitudinal wave the particles are displaced along the direction to the direction the wave travels
