Answer:
B. 30 m down
Explanation:
In physics we have two types of quantities:
- Scalar quantity: it is a quantity which only has a magnitude (e.g: mass and time are scalar quantities, since they only have a magnitude)
- Vector quantity: it is a quantity which has both a magnitude and a direction (e.g: velocity is a vector quantity, since it has a magnitude (the speed) and a direction)
In this problem, we have:
A. 100 ounces of water --> scalar (this is a volume, which has only a magnitude)
B. 30 m down --> vector (this is a displacement, which has both a magnitude (30 m) and a direction (down)
C. 88 mi/s --> scalar (this is a speed, which has only a magnitude)
D. 45 gallons in a bucket --> scalar (this is a volume, which has only a magnitude)
So, the correct option is B.
If we have a vector P, then we name it's components by the axis we project it onto.
In 2D Cartesian coordinate system we have one x axis and one y axis.
Vector P can then be represented with two components: Px and Py.
Px is the component of vector P on the x axis and Py is the component of the vector P on the y axis.
Here is the answer. The external cause code for a passenger that is involved in a MVA that lost control on the highway and hits a guardrail is E815. Your fifth digit is a 1 for a motor vehicle
passenger. You would use an additional E code when a place of occurrence (example, home or parking lot) is
documented. In this case, the location is documented as the highway. Hope this helps.
Answer:
Explanation:
Force is the product of mass and acceleration.
The mass of the Kia Soul is 1200 kilograms and its acceleration is 5 meters per square second.
Substitute the values into the formula.
Multiply.
- 1 kilgram meter per square second is equal to 1 Newton.
- Our answer of 6000 kg*m/s² equals 6000 N
