Is reflecting a congruence transformation?
YES ---- Explanation: An isometry is a distance-preserving mapping. . Geometric figures which can be related by an isometry are called congruent. Reflection preserves distance so it is an isometry. It reverses orientation so it is called an indirect orientationl
Can an object have zero velocity at the same time that it has acceleration?
Absolutely. That's exactly the situation of a rubber ball that was tossed straight up, at the instant when it's at the top of its arc. Any object that's not connected to anything else and is rising or falling has constant acceleration ... the acceleration of gravity. If it was originally launched upward, then it eventually runs out of steam, stops, reverses direction, and starts moving down. At that instant during its constant acceleration, its velocity is zero.
Is there a point at which a prime number's factor pair reverses order?
Yes. After the first factor pair. Ex.1x13,13x1
What times what is 85?
Pairs of positive integer factors of 85 are: 1 x 85 = 85 5 x 17 = 85 And their reverses.
What times what gets you 27?
Pairs of positive integer factors of 27 are: 1 x 27 = 27 3 x 9 = 27 And their reverses.

A radio controlled car rolls 10 miles south then reverses direction and rolls 8 miles north The car has traveled a distance of 18 miles and has a displacement of miles south?
The car has traveled a total distance of 18 miles (10 miles south + 8 miles north), but its displacement is 2 miles south. Displacement is the shortest distance between the starting and ending points, regardless of the actual path taken.
When is displacement at its maximum and velocity equal to zero?
Displacement is at its maximum when an object changes direction, reaching the farthest point from its starting position. Velocity is equal to zero at the moment when an object changes direction, either at the peak of motion in a vertical direction or at the points where an object reverses its direction horizontally.
When the earth ocassionally reverses direction is called what motion?
The earth never reverses direction, nor does any other planet. The APPARENT reversal of direction of some other planets, as seen from earth, is called retrograde motion.
What reverses the action of a prime mover?
An antagonist muscle reverses the action of a prime mover. When the prime mover contracts to produce a movement, the antagonist muscle relaxes to allow that movement to occur in the opposite direction. This coordination between prime movers and antagonists is essential for controlled and coordinated movement.
What river reverses direction twice a year?
Mekong River
When are the displacement velocity and acceleration equal to zero for the motion of a mass on a spring?
The displacement is zero at the equilibrium position, the velocity is zero at the maximum displacement points, and the acceleration is zero at the equilibrium position and maximum displacement points.
Any wind system on a continental scale that seasonally reverses its direction?
Any wind system on a continental scale that seasonally reverses its direction is a monsoon system. It affects large climatic regions.
What is a device that reverses direction of electric current?
A device that reverses the direction of electric current is called a switch or a commutator. These devices can change the flow of current by opening or closing a circuit in the opposite direction. Such devices are commonly used in electrical systems to control the direction of current flow.
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
How does a garage door motor know which direction to operate in if the door is only closed halfway?
The circuitry "remembers" the previous direction and reverses that direction.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The magnetic field direction around the wire reverses when the direction of the current in the wire is changed. This is due to the right-hand rule that states the direction of the magnetic field is perpendicular to the direction of current flow.
