Answer:
The acceleration of the box is 2.
Explanation:
According to Newton's second law of motion, the acceleration of any object will be directly proportional to the net unbalanced force acting on the object and inversely proportional to the mass of the object.
Net force = Mass × Acceleration
So
Since in this case, the box is experiencing a force from east of magnitude 27 N and resisting force of about 17 N from west. So the net force will be the difference of acting and reacting force.
Net force = 27-17 = 10 N.
Thus,
So 2 is the acceleration of the box. Thus the magnitude of acceleration of the box is 2.

Which illustration represents low accuracy and low precision?
Answers
The illustration represents low accuracy and low precision is according to option D.
What is accuracy?
When in an experiment, a value is measured 5 times, then if the values measured are same for most of the time or like three times out of five, it said to be accurate. The phenomenon is accuracy.
Precision is about comparing the values to each other then find them near to each other.
Accuracy compares the experimental value to the theoretical value.
So, when all the values are close to each other but not nearest to the theoretical value, then it is said to be precise but not accurate.
Thus, the correct option for low accuracy and precision is D.

B) It is conduction because the egg is touching the pan.
C) It is convection because you put oil in a frying pan to cook in it.
D) It is convection because you can feel the heat a few inches away from the pan.
Answers
Answer: Option (B) is the correct answer.
Explanation:
A process in which transfer of heat occurring when one object touches another object is known as conduction.
For example, when a pan is heated and then an egg is placed over the pan. Then there will be transfer of heat from pan towards the egg.
As a result, the egg gets cooked because the egg was touching the pan.
Hence, we can conclude that it is conduction because the egg is touching the pan.
Heat transfer is used to fry an egg in a pan, It is conduction because the egg is touching the pan. Hence the correct option is option (B).
When frying an egg in a pan, the primary mode of heat transfer is conduction. Conduction is the transfer of heat through direct contact between two objects or substances.
The pan is heated on a stovetop or a heat source, which causes the pan to become hot. When the egg is placed in the pan, the heat from the pan is transferred to the egg through the process of conduction.
Option A suggests that it is conduction because the egg gets cooked, but this answer does not explain the specific mechanism of heat transfer involved.
Option C mentions convection because oil is used in frying. While oil can enhance the cooking process, convection is not the primary mode of heat transfer in this scenario.
Option D states it is convection because you can feel the heat a few inches away from the pan.
Therefore, option B is the correct answer, as it correctly identifies that the heat transfer involved in frying an egg in a pan is conduction because the egg is touching the pan.
