How does the force block A exerts on block B compare to the force block B exerts on block A?
Draw and label a force diagram for each block, using equality marks on the vectors.
Answers
By Newton's third law, we will see that the force that block A exerts on block B is equal in magnitude but in opposite direction than the force that block B exerts on block A.
Remember that Newton's third law says that whenever two objects interact, they exert equal and opposite forces on each other.
The force that block B exerts on block A is equal to block B's weight, which is:
[tex]W_b = 0.05kg*9.8m/s^2 = 0.49 N[/tex]
Then the force that block A exerts on block B is equal in magnitude but in opposite direction, thus it will be equal to:
F' = -0.49N
Then the diagram is the one that you can see below.

A car was traveling on a straight road at a constant speed of 50 kilometers per hour. Over the next two minutes, the car came to travel 80 kilometers an hour. Which of the following is true?
Answers
The acceleration of the car over the 2 minutes is 0.07 m/s².
Acceleration of the car
The acceleration of an object is the rate of change of velocity of the object with time.
Acceleration of the car over the 2 minutesThe acceleration of the car over the 2 minutes is calculated as follows;
a = Δv/t
a = (v - u) / t
where;
v is the final velocity = 80 km/h = 22.22 m/su is the initial velocity = 50 km/h = 13.89 m/st is the time of motion, = 2 mins = 120 sa = (22.22 - 13.89) / 120
a = 0.07 m/s²
Thus, the acceleration of the car over the 2 minutes is 0.07 m/s².

A train travels 9 meters in the first second of travel, 9 meters again during the second second of travel, and 9 meters again during the third second. What is its acceleration?
Answers
Answer:
Zero
Explanation:
Acceleration is defined as the rate of change in speed. The speed during the first second is 9m/1s = 9m/s. During the second second is again 9m/1s = 9m/s and again 9m/s for the third second. Being the speed the same, the acceleration is 0

A: 0N
B: 50N
C: 100N
D: 150N
Answers
Answer: 0N
Explanation: Hope this helps :)
last time i wrote the wrong answer for the wrong problem :)
For the constant speed, the resultant force on the plane is 0N. So, the correct option is A.
What is Force?A force is defined as the parameter that can change the momentum of an object that can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or pull where force has both magnitude and direction, making it a vector quantity.
For above given information, the plane is moving at a constant speed. According to Newton's first law, the net external force on the aircraft due to the thrust generated by the propeller must be zero and air resistance is equal and in opposite directions to produce zero net force.
Thus, for the constant speed, the resultant force on the plane is 0N. So, the correct option is A.

An object on Earth weighs 600 N and on Mars 100 N. If its mass on Earth is approximately 60 kg what is the mass of the object on Mars?
Answers
Answer:
I think its
10 kg
plzz plzz plzz. mark as brainliest
If the mass of an object is approximately 60 kg on earth then its mass remains the same on Mars which is 60 kg because mass does not change from place to place.
What is mass?Mass in physics is a numerical representation of inertia, a fundamental property of all matter. What a body of matter is fundamentally is the resistance it offers to a change in its speed or location brought on by the application of a force. The more mass a body has, the less of a change a force exerts results. The kilogram is the unit of mass in the International System of Units, and it is defined by Planck's constant as being equal to 6.62607015 × 10⁻³⁴ joules second (SI).
According to the question, the weight of an object depends on gravity which is different from place to place so weight also varies from place to place but the mass is constant everywhere it does not change. So, if the mass of an object is 60 kg on earth then it remains the same on mars also.

Answers
The temperature of a gas will increase and the density will decrease as it
expands.
The expansion of gas happens as a result of an increase in the elastic
