why is it wrong to say a single object all alone is moving

Answers

Answer 1

Answer:

It is wrong to say that "a single object all alone is moving" simply because it goes against Newton's law of inertia.

Explanation:

From Newton's law of inertia, it states that: An object at rest or in constant motion will continue in it's present state unless it is acted upon by an external force.

Which means that a single object by itself cannot move anywhere unless it is acted upon by an external force..

Thus, it is wrong to say that "a single object all alone is moving" simply because it goes against Newton's law of inertia.

Astronauts who traveled to the moon were able to float slightly as they walked along its surface. Why were the astronauts able to do this? The weight of the astronaut on Earth is less than his weight on the moon. The mass of the astronaut on Earth is less than his mass on the moon. The weight of the astronaut on Earth is greater than his weight on the moon. The mass of the astronaut on Earth is greater than his mass on the moon.

Answers

Answer: The weight of the astronaut on earth is greater than his weight on the moon.

Explanation:

The reason I got this answer is because the astronaut will have the same mass on the moon as he does on earth. Also the weight of a person or object is determined by gravity. So since the moons gravity isn’t as strong as earths gravity the astronauts are lighter in terms of weight, and this is how they slightly float.

The weight of the astronaut on Earth is greater than his weight on the Moon.  The third option is correct.

What is gravity?

The force of attraction felt by a person at the center of a planet or Earth is called as the gravity.

The Earth has the acceleration due to gravity, g =  9.81 m/s², Moon has the acceleration due to gravity 6 times less than that of Earth.

A person runs 15.0 km north then turns around and runs 10.0km south.
a) what is his distance?

b) what is the person's displacement?​

Answers

Answer:

A. 25kmB. 15km

Explanation:

In this problem, we are expected to solve for the total distance covered by the person, and the person's displacement.

a) what is his distance?

this can be gotten by summing up all the individual distances covered by the person

total distance= 15+10

total diastance= 25 km

b) what is the person's displacement?​

the displacement is the distance measured away from a point

this can be gotten by subtraction the final distance/point from the initial distance/point

displacement= 25-10

displacement= 15km

water in a cup and a kettle can have the same temperature even though the quantities are different . give reasons​

Answers

Answer:

The reason is because both are exposed to a virtually infinite heat sink, due to the virtually infinite mass  and of the surrounding environment, compared to the sizes of either the cup or the kettle such that the equilibrium temperature, [tex]T_{(equilibrium)}[/tex] reached is the same for both the cup and the kettle as given by the relation;

[tex]\infty M_{(environ)} \times c_{(environ)} \times (T_2 - T_1) = m_{1} \times c_{(water)} \times (T_3 - T_2) + m_{2} \times c_{(water)} \times (T_4 - T_2)[/tex]

Due to the large heat sink, T₂ - T₁ ≈ 0 such that the temperature of the kettle and that of the cup will both cool to the temperature of the environment

Which is always true in a closed system?
Acceleration is not constant.
Mass is not conserved.
Momentum is conserved.
Velocity is constant.

Answers

Answer:

The correct option is momentum is conserved

Explanation:

A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system.

This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.

A load of 800 N is lifted using a block and tackle having 5 pulleys. If the applied effort is 200 N, calculate
i. Mechanical advantage
ii. Velocity ratio
iii. Efficiency
iv. Output work if load is lifted 5m high.
v. Input work

Answers

Explanation:

Load=800N

Effort=200N

1. Mechanical Advantage = LOAD/EFFORT

= 800N/200N

= 4

2 Velocity Ratio = no. Of pulleys =5

3. Efficiency = Mechanical advantage / velocity ratio × 100%

= (4/5)×100%

=80%

4. output work= load×load distance

= 800N × 5m

= 4 × 1000J

5. Efficiency = (output work/input work) ×100%

Or, 80% = (4000J/input work) ×100%

Or, 80%/100% = 4000J/inputwork

Or, 4/5 = 4000J/inputwork

Or, input work =4000J × 5/4

Input work = 5×1000J

Teaching and technology programs are the longest. I study in the technical program. I want to be a gardener. When you finish the two years of the technical program, you can start working immediately without going to university. In professional careers you need to study more than in technical careers and you need to go to university. There are technical majors in the United States, but not in all schools. In the United States, after completing technical or general studies in four years, you can go to college for professional studies.

Both countries offer general programs in all high schools. Both countries require five years of university studies before any technical programs.
