Answer:
Inclined plane.
Explanation:
Geometrically, a screw is a narrow inclined plane that is wrapped around a cylinder. Like the other simple machines a screw can amplify force; a small rotational force (torque) on the shaft can exert a large axial force on a load.
A screw is a cylinder with a head (solid top) at one end and a pointed tip (like a nail) at the other end.
The mechanical advantage of the screw depends on the space between the threads and the length (and thickness) of the screw. The closer the threads are, the greater the mechanical advantage. It is easier to drive a screw into an object if the thread spacing is smaller.
Answer:
The electrical loads in parallel circuits each have the same voltage drop, with equals the total applied voltage of the circuit.
Explanation:
I did some research and the voltage drop across any branch of a parallel circuit is the same as the applied voltage.
Matter makes up all of the universe
Answer:
a = 5 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 20 [m/s]
Vo = initial velocity = 10 [m/s]
t = time = 2 [s]
a = acceleration [m/s²]
Now replacing:
![20 =10 +a*2\\10=2*a\\a=5[m/s^{2} ]](https://tex.z-dn.net/?f=20%20%3D10%20%2Ba%2A2%5C%5C10%3D2%2Aa%5C%5Ca%3D5%5Bm%2Fs%5E%7B2%7D%20%5D)
