A certain corner of a room is selected as the origin of a rectangular coordinate system. If a fly is crawling on an adjacent wal
Helga [31]

Answer:

2.59 m

Explanation:

Coordinates of origin = (0, 0)

Coordinates of Point p where the fly reach = (2.3 m, 1.2 m)

Use the distance formula of coordinates to find the distance between the origin and the point P.

d=\sqrt{\left ( x_{2}-x_{1} \right )^{2}+\left ( y_{2}-y_{1} \right )^{2}}

d=\sqrt{\left ( 2.3- 0 \right )^{2}+\left ( 1.2-0 \right )^{2}}

d = 2.59 m

Thus, the distance between the origin and the point P is 2.59 m.

Two people push on the same door from opposite sides as shown. A man pushes on a door from the left. A woman pushes on the door
AURORKA [14]

Answer:

The door will move when the forces exerted by each individual becomes unbalanced.

Explanation:

The Door will only move when the forces exerted by each of the individual is unbalanced i.e. when the Torque is unbalanced

This is because there will only be a reaction or movement of an object  when the applied force > resistant force acting on the object.

example : An object at rest will only move when the applied force is  greater than the frictional forces acting on the object at rest.

Electromagnetic waves differ from other types of waves because they are (2 points)
saveliy_v [14]

Answer:

b. able to travel through a vacuum.

Explanation:

The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum.

These waves do not require materials in a medium for propagation.

  • Electromagnetic waves are formed by the propagation of the electric and magnetic fields.
  • They vibrate at an angle of 90° .
  • They are unlike like mechanical waves that requires that requires materials in medium for their propagation.
