What else can I help you with?
Is it possible for two substances of the same volume to have a different mass but the same density?
No
Name two elements have the same mass numbers?
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
What two subatomic have about the same mass?
These particles are: proton and neutron.
How would the orbits differ if a star and planet were of similar mass to each other?
Two objects of the same mass will also move in elliptical orbits. Whether the two bodies are of the same mass or different, one focus of the elliptical orbit is the center of mass (barycenter).
If two objects have the same volume and density do they ave the same mass?
Yes, if two objects have the same volume and density, they will have the same mass. This is because mass is calculated by multiplying density and volume; therefore, having the same density and volume means the objects will have the same mass.
Is it true two objects with the same mass will always have the same momentum?
No, two objects with the same mass will not always have the same momentum. Momentum is a vector quantity that depends on both mass and velocity. If the objects are moving at different speeds, they will have different momenta even if they have the same mass.
Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
2 objects with same velocity have same momentum if they have the same?
mass. Momentum is the product of an object's mass and its velocity, so if two objects have the same velocity and mass, then their momentum will be the same.
Will two objects that have the same mass that are dropped from two different heights meet at the same speed?
No because 'g' is irrespective of the object's mass.
What two things have the the same mass?
Two objects with the same mass would have the same amount of matter, meaning they would weigh the same when measured.
Can two cars of different mass have the same kinetic energy?
Yes, two cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy is dependent on both mass and speed, so if the speeds are equal, the kinetic energy will be the same regardless of the mass.
Do two objects that have the same mass and velocity always have the same momentum?
Yes, if two objects have the same mass and velocity, they will always have the same momentum. Momentum is calculated as the product of an object's mass and velocity, so if these values are the same for both objects, then their momentum will also be the same.
What two country's share the same land mass?
Asia and Europe both share the same land mass.
If 2 objects have the same density what else must be the same?
If two objects have the same density, then their mass and volume must also be the same. Density is calculated by dividing an object's mass by its volume, so if the density is the same for two objects, it means that the ratio of their mass to volume is equal.
How can two objects have the same amount of kinetic energy?
Two objects can have the same amount of kinetic energy if they have the same mass and velocity. Kinetic energy is given by the formula KE = 0.5 * mass * velocity^2, so if both objects have the same mass and velocity, they will have the same kinetic energy.
When two properties of a crayon will stay about the same after the crayon is melted?
The two properties of a crayon that will stay about the same after being melted is it's color and mass.
