Answer: The pull of the Moon's gravity on Earth is the primarily cause of tides and the pull of the Sun's gravity on Earth is the secondary cause. The Moon has a greater effect because, although it is much smaller than the Sun, it is much closer. The Moon's pull is about twice that of the Sun's.
in general, what happens to the density and temperature of a gas as it expands?
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
collision of the atoms. This is as a result of the increase in temperature which causes the atoms to be more spatially arranged.
The density of gas also reduces as a result of the same number of gas
molecules occupying more volume.

A plane is flying through the sky at a constant speed. The thrust of the aeroplane (making it go forwards) is 100N. Air resistance is also acting on the plane. What must the resultant (overall) force be on the plane?
A: 0N
B: 50N
C: 100N
D: 150N
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 amusement park ride has two identical carriages that revolve around the center of the ride’s axle, as shown in the figure. both carts travel at a constant tangential speed at all points along the circular path. at what position is the total mechanical energy of the cart-cart-earth system at its maximum value?
The principle of conservation of energy allows to find the result for the mechanical energy of the system is:
Mechanical energy is conserved at all points, therefore at all points it has the same value.
Mechanical energy is defined by the sum of the kinetic energy and the potential energies.
Em = K + U
In the principle of energy conservation, it establishes that energy cannot be created or destroyed, it is only transformed, in the case of no friction, mechanized energy is conserved at all points.
They indicate that the system is rotating, which is why it is subjected to a force that expends its energy in changing the direction of the speed to keep the system in rotation, so the speed of the system remains constant.
Em = K = ½ I w²
Consequently, using the principle of conservation of energy we can find the result for the mechanical energy of the system is:
Mechanical energy is conserved at all points, therefore at all points it has the same value.

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?
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.

. A small toy car having 300 grams of mass and going straight with an initial velocity of 13 m/s. When the toy car collides with an obstacle, a resistive force of 4 N acts upon it. The speed of the toy car reduced and reached 8 m/s. Draw its free body diagram and then find the time for the toy car to be into rest position?
The free-body diagram is attached in the image below. The time for the toy car to be in rest position is 0.6 s
From the given information:
The mass of the toy car = 300 g = 0.3 kgThe initial velocity (u) of the car = 13 m/sThe resistive force F_r acting on the car = 4 NThe speed of the car (v) = 8 m/sA force is regarded as a push that causes an alteration in motion of an object within a specified distance. It is usually expressed by the formula:
Force = mass × acceleration∴
acceleration = Force/massacceleration = (4 / 0.3) m/s²acceleration = 13.33 m/s²Using the first equation of motion for the time to bring the car to rest from it reduced speed of 8 m/s;
v' = v + atsince the final speed to bring the car in rest position is (0), then:
0 = 8 - 13.33(t)
13.33(t) = 8
t = 8/13.33
t = 0.6 seconds
