Vectors are used to represent physical magnitudes that have an associated address. For example, if we want to represent the displacement of an object, it is not enough to describe only the distance as 10 meters, it is also necessary to describe in which direction the displacement occurred, for example, 30 ° towards the northeast.
Therefore the vectors are measured in one or several dimensions that include a magnitude and an address.
The correct option is the last:
"<em>a measurement in more than one dimension that includes a magnitude and a direction</em>"
Water was confirmed to be on the sunlit surface of the Moon
Answer:
direction does the axis of rotation tilt toward after the blow is the z- direction
Explanation:
This is because
Due to the blow, there is a impulse imparted on the ball which gives a change in linear momentum () in the x direction
Thus When cross product of momentum in x direction is taking with r vector, we will get resultant in z direction. Hence change in angular momentum will be z direction.
2 Ways Acceleration can be changed are:
i) Increasing or decreasing the velocity of a moving object.
ii) Change of direction of the moving object.
Answer:
b. 48.0 g.
Explanation:
Given;
mass of the exoplanet, 
radius of the exoplanet, 
The acceleration due to gravity of the planet is calculated as;
Therefore, the correct option is b. 48.0 g
