A basketball is made of matter. Fire itself is not matter. However, the wood that burns is matter. A basketball is very different from a fire. What are some differences that might make a basketball matter but not a fire?
Answer: A basketball is something that can have a physical or chemical change done to it.
Explanation:
A basketball is made of matter. The fire itself is not a matter however, the wood that burns is matter. A basketball is very different from a fire because a basketball has some mass in it on the other hand fire does not contain any mass
What is the matter?Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
For any substance to be considered as matter it must have to contain some mass and occupies some space.
As given in the problem statement a basketball is made of matter. The fire itself is not a matter however, the wood that burns is matter. A basketball is very different from a fire because a basketball has some mass in it on the other hand fire does not contain any mass.
For any substance to be considered as matter it must have to contain some mass and occupies some space.
Thus, a basketball is considered a matter but fire is not considered a form of matter.

A binary star system that is detected from the drop in luminosity as one star passes in front of the other is called ___________.
A binary star system that is detected from the drop in luminosity as one star passes in front of the other is called eclipsing. It has two stars.
What is a binary system?A binary system is a system composed of two stars that exert gravitational forces on a group of celestial bodies.
In a binary system, planets and celestial bodies can exhibit well-defined or irregular (very unstable) orbits.
The eclipsing binaries are stars where binary planets orbit in a plane containing the same line of vision, thereby eclipsing each other.

How long will bus take to travel 150 km at an average speed of 40km/hr
Answer:
3.75 hours
Explanation:
By [tex]v = \frac{d}{t}[/tex]
where v is the velocity (or speed in this case)
d is the distance travelled
t is the time taken
[tex]t = \frac{150}{40}=3.75[/tex]
Therefore it takes 3.75 hours for the bus to travel 150 km and 40 km/hr.

a 50kg person is standing still in ice skates throws their 2.0kg helmet to the right at 25m/s while on a friction less surface. what is the final speed of the person
Answer:
Vp = 1 [m/s]
Explanation:
In order to solve this problem, we must use the principle of conservation of the amount of movement. In the same way, analyze the before and after of the actions.
The moment before
The 50kg person is still hold (no movement) with the 2kg helmet
The moment after
The helmet moves at 25[m/s] in one direction, the person moves in the opposite direction, due to the launch of the helmet.
In this way we can apply the principle of conservation of movement, expressing the before and after. To the left we have the before and to the right of the equal sign we have the after.
Σm*V1 = Σm*V
where:
m = total mass = (2 + 50) = 52[kg]
V1 = velocity before the lunch = 0
(50 + 2)*V1 = (25*2) - (Vp*50)
0 = 50 - 50*Vp
50 = 50*Vp
Vp = 1 [m/s]

How does the pattern of magnetic stripes give evidence for seafloor spreading?.
Answer:
These patterns of stripes provide the history of seafloor spreading. Geophysicists can read these patterns from the magnetic anomalies they measure with a magnetometer. Where the magnetic wiggles, or anomalies, are broader, the spreading rate has been faster.

Which type of wave is a combination of two waves?
mechanical waves
longitudinal waves
surface waves
transverse waves
Answer:
Standing wave,Also called stationary wave,combination of two waves moving in opposite direction,each having the same amplitude and frequency.They phenomenon is the result of interference;that is when waves are superimposed,their energies are either added together or cancelled out.
Explanation:
hpe it hlps u<°>
The combination of two waves is "mechanical waves". The correct option is A.
What is a mechanical wave?A mechanical wave is a type of wave that requires a medium to travel through. In a mechanical wave, energy is transferred through the motion of particles in the medium, rather than the transfer of matter. Examples of mechanical waves include sound waves, water waves, and seismic waves.
In a mechanical wave, energy is initially added to a small region of the medium, which creates a disturbance that propagates outward as a wave. As the wave travels, particles in the medium oscillate back and forth around their equilibrium positions, transferring energy to neighboring particles. The wave continues to travel until it encounters a boundary, where it may be absorbed, transmitted, or reflected.
Mechanical waves can be classified as transverse waves or longitudinal waves, depending on the direction of particle motion relative to the direction of wave propagation. In a transverse wave, particle motion is perpendicular to the direction of wave propagation, while in a longitudinal wave, particle motion is parallel to the direction of wave propagation.
Mechanical waves are an important aspect of many natural phenomena and technological applications. They play a crucial role in fields such as acoustics, optics, and seismology, and have applications ranging from medical imaging to telecommunications.
Here in the Question,
A combination of two waves can be any type of wave, but it is most commonly a type of mechanical wave. Mechanical waves are waves that require a medium to travel through, such as sound waves or water waves.
The other three types of waves mentioned - longitudinal waves, surface waves, and transverse waves - are all specific types of mechanical waves.
Longitudinal waves are waves in which the particles of the medium vibrate back and forth parallel to the direction of wave propagation. Examples include sound waves and seismic waves.
Transverse waves are waves in which the particles of the medium vibrate perpendicular to the direction of wave propagation. Examples include light waves and electromagnetic waves.
Surface waves are waves that occur at the interface between two different media, such as the interface between air and water. Examples include ocean waves and seismic waves.
Therefore, the most appropriate answer to the question would be "mechanical waves".

Is it possible to apply the laws of Newton's dynamic to the motorcycle of the moon and the earth?
Answer:
Yes, it is possible
Explanation:
If possible, since Newton's laws are based on the motion of bodies that have mass. An example of how a vehicle can be moved on the moon was seen during lunar exploration where American astronauts drove a buggy-cart on the moon for a period of time.
We must remember that Newton's Second Law tells us that force is equal to the product of mass by acceleration. In this way we have:
F = m*a
where:
F = force = [N]
m = mass [kg]
a = acceleration [m/s²]
The force is produced by internal combustion or by electric action of the vehicle engine, the mass is the mass of the vehicle plus that of the crew member and the acceleration is the one that develops due to the change of speed, from rest to a certain speed.
Which waves can travel through a vacuum?
A) light waves
B) Ocen waves
C) Sound waves
D) mechanical waves
Must a magnetic force be exerted on the charge carriers in a conducting loop in order for a current to be induced in the loop
It is true that a magnetic force must be exerted on the charge carriers in a conducting loop for the current to be induced in the loop.
What is Magnetic Force?Magnetic Force refer to force that attract or repel between electrically charged particles mainly because of their movement. This force is responsible for attraction of magnets.
The force on a conduction current loop in a uniform magnetic field is always zero. A current loop with magnetic moment pointing to the left magnitude decrease to the right.
Therefore, It is true that a magnetic force must be exerted on the charge carriers in a conducting loop for the current to be induced in the loop.
