Speed of particle B is 2v₀/3 m/s to the left. Particle A and particle B will always have equal speed since they experience equal forces.
Conservation of energyThe speed and direction of the particle B is determined by applying the principle of conservation of energy as follows;
K.E₁ + P.E₁ = K.E₂ + P.E₂
[tex]\frac{1}{2} Mv^2_A + \frac{G}{r^2} = \frac{1}{2} Mv^2_B + \frac{G}{r^2} \\\\ \frac{1}{2} Mv^2_A = \frac{1}{2} Mv^2_B\\\\v^2_A = v^2_B\\\\v_A = v_B[/tex]
[tex]v_B = \frac{2v_0}{3} \ m/s \ to \ the \ left[/tex]
At any given position, the speed of particle A and particle B will be equal, since they experience equal force and they have equal masses.
The complete question is below:
Particle A and particle B, each of mass M, move along the x-axis exerting a force on each other. The potential energy of the system of two particles assosicated with the force is given by the equation U=G/r 2, where r is the distance between the two particles and G is a positive constant.

A block of mass 0.4kg on a horizontal surface is attached to a horizontal spring of negligible mass. The other end of the spring is attached to a wall and there is neglig ble friction between the block and the horizontal
surface. The center of mass of the block is stretched a horizontal distance 0.25 beyond its equilibrium position and released from rest such that the block spring system undergoes simple harmonic motion. A graph
of the spring potential energy of the block spring system as a function of the horizontal position of the center of mass of the block is shown. The positive direction is considered to be to the right
of the force exerted by the spring on the block as a function of the block's horizontal position
A loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.
What is simple harmonic motion?Simple harmonic motion is the periodic motion of an object along a straight line, such that the acceleration of the object is directed towards a fixed point on that line and is proportional to its distance from that point.
Example of a simple harmonic motion is the motion of a loaded spiral spring.
The restoring force on the spring is directly proportional to the extension of the spring and the spring constant.
The period of motion, T when a mass, m is attached to a spring with spring constant k,is given as:
T = 2π√(m/k)Therefore, a loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.

James passes a magnet over a pile of paperclips and the magnet picks up 2 of the paperclips. Then he passes a different magnet over the pile of paperclips and it picks up 6 paperclips. Which of the
following is NOT a testable
hypothesis that James might develop based on this data?
1. a weaker magnet will pick up more
paperclips than a stronger magnet
2. all magnets pick up paperclips, but the
number of paperclips depends on the
magnet
3. magnets will pick up metal objects but
not plastic objects
4. a stronger magnet will pick up more
paperclips than a weaker magnet
Answer: 2
Explanation:
The statement "All magnets pick up paperclips, but the number of paperclips depends on the magnet" is neither a hypothesis nor testable.
The hypothesis that is not testable based on the given data is magnets will pick up metal objects but not plastic objects. Option C is the correct answer.
The reason this hypothesis is not testable based on the given data is that the information provided only pertains to the number of paperclips picked up by different magnets. It does not provide any information or evidence regarding the ability of magnets to pick up metal objects versus plastic objects. Option C is the correct answer.
In order to test this hypothesis, we would need data or experiments specifically focusing on the interaction between magnets and metal objects as well as magnets and plastic objects. The given data only provides information about the number of paperclips picked up by different magnets, which does not support or refute the hypothesis about the ability of magnets to pick up different materials.

A boy is swimming , identify the action and reaction
Answer:

Explanation:
A motorist drives 5 km east then drives 5 km north. Calculate their distance travelled and their displacement.
Answer:
See
distance is 10 km
displacement is 5√2 km
Explanation:
DISTANCE:
Distance is scaler so, it doesn't depend on the direction
so distance is 5+5 which is 10
DISPLACEMENT:
Displacement is a vector, so, it depends on direction.
Now when we see north and east, they form a right angle, so we need to calculate the hypotenuse of the triangle for displacement as it is the shortest route between the two points.
Let hypotenuse be h
5² + 5² = h² Moved 5 km in east and north so values are 5h² = 25+25h² = 50h = √50h=5√2Hope it helps

What is the function (job) of the genes in protein synthesis (how proteins are made in the cell)?
Answer:
Most genes contain the information needed to make functional molecules called proteins. A few genes produce regulatory molecules that help the cell assemble proteins.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.

On top a coiled spring labeled wave a with coils, which are widely spaced then tightly spaced then widely space. on bottom a coiled spring labeled wave b with coils, which are widely spaced then very tightly spaced then widely space. which statement can be made about waves a and b? wave a has a lower amplitude than wave b. wave a has a higher amplitude than wave b. wave a has a lower frequency than wave b. wave a has a higher frequency than wave b.
Answer:
Wave A has a lower frequency than Wave B.
Explanation:
Frequency is the number of waves passing through the unit time.
As the statement of the question says that the coils in wave A are widely and tightly spaced.
While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.
Therefore more coils will pass through a fixed point in unite time and more will be the frequency.
Answer:Wave A has a lower frequency than Wave B.
