Determine the mass of the object below to the correct degree of precision.
OleMash [197]

Answer : The correct degree of precision is 272.94 g.

Explanation :

Precision : It is defined as the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 2.7 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

In the given figure, the value of mass of object is 280 g. From the given options we conclude that the 272.94 g is more close to 280 g and has maximum number of decimal places. So, 272.94 g measurement is said to be precise.

Therefore, the correct degree of precision is 272.94 g.

0.8 mj of energy are used by a blender in 3 and a half minutes what is the power rating on the blender
solong [7]

Answer:

   Power rating on the blender = 3809.52 Watts

Explanation:

   We have expression for power equal to ratio of work and time,

   Energy used by blender = Work done by electricity = 0.8 MJ = 0.8*10^6J=800000J

   Time of using blender = 3.5 minutes = 210 seconds

   So power of blender = 800000/210 = 3809.52 Watts

   Power rating on the blender = 3809.52 Watts

When a substance is poured from one container to another, its shape changes but its volume does not, what state of matter is the
lianna [129]

Answer: When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel. Furthermore, when a liquid is poured from one vessel to another, it retains its volume (as long as there is no vaporization or change in temperature) but not its shape.

Explanation: A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.
