John Purchased 6 Kg And 500 Kg of suger and 12kg and 400g of rice.what is the total mass of the suger and rice that he purchased

gulaghasi [49]

Answer:

Total Mass = 18 kg 900 gram

Explanation:

Given:

Mass of sugar buy = 6 kg 500 gram

Mass of rice buy = 12 kg 400 gram

Find:

Total Mass

Computation:

Total Mass = Mass of sugar buy + Mass of rice buy

Total Mass = 6 kg 500 gram + 12 kg 400 gram

Total Mass = 18 kg 900 gram

Find the total displacement of a mouse that travels 1.0m north and then 0.8m south.

Neko [114]

In this case two vectors are colinear and they have an opposite orientation.
N + ( - S ) = N - S = 1 m - 0.8 m = 0.2 m
Answer:
The total displacement is 0.2 m north.

n a presentation about measuring mass, one of your classmates states, "Two objects of the same size will always have the same ma

Neporo4naja [7]

Answer:
The statement is not correct.

Reason:
If two objects have the same mass, their respective densities determine their volumes.
By definition,
density = mass/volume.
or volume = mass/density.

Therefore if two objects have the same mass, the mode dense object (with higher density) will occupy less volume than the other object.

For an object moving with constant negative acceleration, draw the following:

Tcecarenko [31]

Answer:

Kindly find the graphs attached

Explanation:

For figure 1: There is a steady increase in the position of the object as time increases. This is because despite the negative acceleration (deceleration), the object continues to move and cover more ground as time goes by.

<em>The straight line graph is observed because the acceleration is constant and not varying.</em>

For Figure 2: The graph of velocity vs time will have an inverted nature. This is because since the object is decelerating, it is reducing in its velocity as time goes by (increases). <em>This is also in a straight line since the deceleration is constant.</em>
