When comparing the speed of two objects why must you use the same units?

Speed consists of distance over time. You have to use the same measures of distance and time or the comparison is meaningless. You have to agree on the units in advance, or you have to convert to them.

Two objects with the same velocity must be moving in the same?
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.
What must be included when reporting an objects velocity-?
When reporting an object's velocity, you must include both the speed of the object and its direction. Velocity is a vector quantity that describes how fast and in which direction an object is moving. This can be represented using units such as meters per second (m/s) or kilometers per hour (km/h) along with a direction (e.g., north, east).
Can resistance speed up moving objects as well as slowing them down?
Resistance can slow down moving objects by opposing their motion, but it cannot speed them up. When an object encounters resistance, such as air resistance or friction, it must overcome these forces to maintain its speed or acceleration. The resistance acts as a hindrance that requires additional force or energy to counteract.
How speed increase with velocity?
Speed increases in a linear relationship with velocity. As velocity increases, speed also increases proportionally. This relationship is true for objects moving in a straight line at a constant acceleration.
In order for heat to be transferred between two objects by conduction?
the objects must be in physical contact with each other, and there must be a temperature difference between them. Heat will flow from the object with a higher temperature to the one with a lower temperature until thermal equilibrium is reached.
When comparing storage alternatives you must sacrifice speed to gain?

What is the ppm of 1mg in 1000ml?
You are comparing units of mass with units of volume. You must first decide whether you want parts per million (volume), or parts per million (mass). Then you must either convert the volume to mass, or the mass to volume. For this purpose, you have to know the density of the involved substances.You are comparing units of mass with units of volume.

To objects with the same velocity must be moving in the same?
Same speed, same direction.
In order to figure out the kinetic energy of an object you must know the objects?
... mass and speed.
How many hours are equal to 219 miles?
You can not convert between units of time and units of length - they measure completely different things. If it is a speed problem, you must know ore assume the speed, then divide the number of miles by the speed.
How do you find the longest wavelength?
By comparing the numbers. If the wavelengths are specified in different units (for example, meters and millimeters), you must convert them all to the same unit first.
What are two units of measure for speed?
In order to measure speed, a unit for distance and a unit for time must be used. Common units with which speed is expressed are meters per second (m/s), miles per hour (mph), and kilometers per hour (km/h).

What must be absent for two objects of drastically different masses to fall at the exact same speed if they rely only on gravity?
Air resistance must be absent for two objects of drastically different masses to fall at the exact same speed when relying only on gravity. This is because air resistance affects the rate at which objects fall through the atmosphere, causing lighter objects to experience more air resistance than heavier objects.
