What else can I help you with?
Downward velocity is considered a negative. true or false?
Downward velocity is considered a negative. This is a true statement.
Is it true that Humans are responsible for the direction of evolution during the process of artificial selection?
Yes, humans are responsible for selecting desirable traits in plants and animals through artificial selection, which can influence the direction of evolution. By selectively breeding individuals with preferred traits, humans can drive the evolution of domesticated species in a specific direction.
Do all animal cells contain the same type and quantity of organelles?
Organelles are contained within cells; each cell contains many of them. Some animals may by coincidence have the same number of organelles as another animal, but as a general rule they do not.
Are A group of cells is called ORGAN true or false?
False. A group of cells is not called an organ. An organ is a collection of tissues that work together to perform specific functions in the body.
Increasing the intensity of light decreases the rate of photosynthesis true or false?
False. Increasing the intensity of light typically increases the rate of photosynthesis, up to a certain point where other limiting factors may come into play.
True or False A vector quantity has direction a scalar quantity does not?
True. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.
Is momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Is Momentum is scalar quantity true or false?
False. Momentum is a vector quantity because it has both magnitude and direction.
Is vector quantity always the same as a scalar quantity true or false?
False. Vector quantities have both magnitude and direction (such as velocity and force) while scalar quantities only have magnitude (such as speed and mass).
Is distance a vector quanity?
It can be both true or false - you can treat distance as a scalar, or as a vector. If you say that (say) the distance from the cities of Cochabamba and Quillacollo is 13 kilometers - WITHOUT specifiying the direction - then it is a scalar. If you also say that Quillacollo is to the east of Cochabamba, then it is a vector.
Is momentum a scalar quality?
A vector quantity is one which transforms like the coordinates. In other words, if a coordinate system is transformed by an operator , any vector quantity in the old coordinate system can be transformed to its equivalent in the new system by the same operator. An example of a vector quantity is displacement (r). If displacement is a vector, the rate of change of displacement (dr/dt) or the velocity is also a vector. The mass of an object (M) is a scalar quantity. Multiplying a vector by a scalar yields a vector. So momentum, which is the mass multiplied by velocity, is also a vector. Momentum too transforms like the coordinates, much like any other vector. The definition of a vector as a quantity having "magnitude and direction" is simply wrong. For example, electric current has "magnitude and direction", but is a scalar and not a vector.
60 miles per hour would be a Scalar quantity because it represents a Magnitude but not Direction. is true or false?
TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
Is vector quantity acceleration?
no, acceleration is not a vector quantity. its false
Time and velocity are both vectors.?
false
Acceleration is a vector quantity true or false?
True
Acceleration is a vector quantity?
no, acceleration is not a vector quantity. its false
Are speed and distance a pair of vector quantities?
Speed and distance are examples of scalar quantities, meaning they only have magnitude. Velocity and displacement are vector quantities, meaning they have both magnitude and direction.Examples of scalar quantities:speed (s) - 10 m/s or 36 km/hdistance (d) - 100 m or 0.1 kmExamples of vector quantities:velocity (v) - 10 m/s [E] or 36 km/h [E]displacement (Δd) - 100 m [E] or 0.1 km [E]The value in square brackets (for vector quantities) indicate direction and include, but not limited to:[S], [N], [E], [W], [45°], [45° E of S], [45° S of E], [forward], [backward] [up/↑], [down/↓], etc...
