Answer:
Draw line perpendicular to mirror
Angle of incidence = angle between incident ray and perpendicular
Angle of reflection = angle between reflected ray and perpendicular
32 + 32 = 64
Angle of incidence = angle of reflection = 32 deg
If any current is PRODUCED in an individual home, like with
a windmill or solar panels, it is direct current (DC).
The current SUPPLIED to homes by the local utility company
is alternating current (AC).
If you add both numbers together it makes 105 but we’re talking time so it’ll be an hour and 45 minutes for them to clean their apartment.
Answer:
4. To the east
Explanation:
Friction forces always act in the opposite direction that an object tends to move in. In this case, when the truck accelerates to the east, the crate tends to move to the west due to inertia (the tendency for an object to remain at rest or at constant speed). In order to stop the crate from moving, there needs to be a friction force to the east.
Answer:
Wherever the slope is increasing or decreasing the sharpest.
Explanation:
In a distance v time graph, the slope is the speed. So the sharper the slope, the faster the object is going.
