Answer:
The answer to your question is: a = 1.99 m/s²
Explanation:
Data
mass = 20 kg
angle = 56°
Force = 71 N
horizontal acceleration = ?
Process
Find the horizontal force
cos Ф = adjacent side / hypotenuse
adjacent side = hypotenuse x cosФ
adjacent side = 71 x cos 56
a.s. = 39.70 N
Newton's second law
F = ma
a = F/m
a = 39.7 / 20
a = 1.99 m/s²
A. because none of the other answers make sense, there is no air in space, acceleration would change the velocity, force would imply something moved it which is highly unlikely (unless we are talking about starwars), and inertia is a tendency to do nothing or to remain unchanged or a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
Answer:
Explanation:
From the question we are told that
Area of plate
Angle of inclination 
Velocity 
Thickness of oil 
Weight of plate 
Generally the equation for shear force is mathematically given by
Therefore viscosity is given by
There are two main types of mechanical energy. They are motion energy and stored mechanical energy.
hyou have any race is not a big deal but I hope you have a great day at work too hard to get to the same placed an answer to my house
