Sum the vector components:
Dx = 225* Cos(180)+ 78*Cos(225)= -280.154 km
Dy = 225* Sin(180)+ 78*Sin(225) = -55.154 km
displacement:
Sqrt(Dx^2+Dy^2) = 285.532 km
Arctan(Dy/Dx) = 191.137degrees CCW
OR:
11.137 degrees South of West
Nuclear. She named heat, light, sound energy correctly but nuclear energy is incorrect.
At 0.1m, the restoring force would be 25 Newtons. It would probably not be possible to stretch to 5 meters because that would cause a restoring force of 1250 Newtons.
Length of the ramp (L) = 4.0 m = Distance traveled by the effort
Height of the inclined plane (h) = 2.0 m = Distance traveled by the resistance
IMA = Ideal mechanical advantage


IMA = 2.0
Hence, the IMA of the inclined plane is 2.0
Answer:
False
Explanation:
The shortest distance between the starting point and the finishing point is called the Displacement. This is a vector quantity
It is obtained by subtracting the components of staring point from the components of finishing point

It can be expressed in terms of the components in three dimensional space.
Ex.
