The tension in the string at the bottom is larger than the tension in the string at the top by six times the weight of the ball as 4mg + 2mg = 6mg.
Calculate the tension in the spring?Let V₁ be the speed of ball at bottom and V₂ at top, If Ttop and Tbottom are tensions :-
According to conservation of energy;
1/2mv₁² = 1/2mv₂² + mg(2R)
m(v₁² - v₂²) = 4mgR
Tbottom = mv₁²/R + mg
Ttop = mv₂²/R - mg
Tbottom - Ttop = m/R(v₁² - v₂²) + 2mg
⇒ 4mg + 2mg = 6mg
What is tension?Any physical object that is in contact with another one can apply forces to that object. Depending on the types of objects in touch, we label these contact forces differently. We refer to the force as tension if a rope, string, chain, or cable is one of the things applying the force.

What would happen if the price of an inelastic good went up?.
The total revenue, on the other hand, rises as a result of the higher price and constant quantity demanded for an inelastic good when the price is raised and the demand remains the same.
Inelastic demand is when consumer preferences do not change as much as changes in the price of a good. When the price increases by 20% while the decrease in demand is only 1%, the demand is said to be inelastic. Elastic items are usually required when appropriate substitutes are not available. The items with the most prevalent inelastic demand are utilities, prescription drugs, and tobacco products. Businesses that sell these items may be more tolerant of price changes because demand for them never ceases, regardless of price changes. The amount of a good that is purchased has no effect on price changes when the price elasticity of demand for that good is completely inelastic; rather, higher prices will always lead to higher overall income. whenever the cost of a thing or service changes, the demand for such items remains mostly stable.

What do you predict would happen if you brought a negatively charged balloon next to an uncharged piece of paper?.
The charged balloon sticks to a wall due to electrostatic force between the charged balloon and the wall.
What happens when a charged balloon is brought close to another charged balloon?The negatively charged balloon contains an excess of elections. Like charges repel, so the electrons in the balloon repel the electrons in the paper.Therefore, a part of the paper would gain a slightly positive charge. Opposite charges attract, so the paper would want to stick to the balloon/will follow the balloon.When you bring the balloon near a little piece of paper, the negative balloon repels the electrons in the paper so part of the paper near the balloon is positive. Since positive and negative attract, the paper moves toward the balloon. The negatively charged balloon attracts the paper.When the negatively charged balloon approaches a wall, the negative charges in the wall are repelled (or pushed away). This leaves a positive charge on the wallboard at the spot where the balloon touches.Because electrons are negatively charged, the balloon acquires a net negative charge. The balloon's negative charges are attracted to the positive charges in the can, and so the can rolls toward the balloon. As the balloon is pulled away from the can, the can will continue to roll toward the balloon.Any charged object - whether positively charged or negatively charged - will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.To learn more about balloon sticks refer to:

(b) 2nd, 4th, 7th and 13th harmonic are being heard and show a rough spectrum diagram of the signal.
How to find %THD ?(a). V = 2.1v
let V₂, V₄, V₇ and V₁₃ be components that is 880Hz, 1.76KHz, 3.08KHz and 5.72KHz.
Then, 20 ㏒ V₂/V₁ = -7 ⇒V₂ = 0.938 V

what is shear stress ?
Shear stress, often denoted by (Greek: tau), is the component of stress that is coplanar with a material cross section. It is caused by shear force, a component of the force vector parallel to the material cross section. Normal stress, on the other hand, is caused by the force vector component that is perpendicular to the material cross section on which it acts. Shear stress is a force that tends to distort a material by causing slippage along a plane or planes parallel to the imposed stress. The resulting shear is extremely important in nature, since it is directly tied to the downslope flow of earth elements and earthquakes.

In some of the situations, the mass is at rest and remains at rest. In other situations, at the instant described, the mass is in the middle of an oscillation initiated by a person pulling the mass downward 5 cm from its equilibrium position and releasing it. Ignore both air resistance and internal damping in the spring. Assume the spring is a perfect Hooke's law spring for all the oscillations in this problem. As the time the oscillation occur, indicate whether the force vector requested points up (U), down (D), or has magnitude zero (0). 1. The force on the mass exerted by the spring when the mass is at its equilibrium position and is at rest. 2.

A 50 gram mass is hanging from a spring whose unstreached length is 10 cm and whose spring constant is 2.5 N/m. Base on the data above, it can describe of the following events:
1. In equilibrium state, the force given on the mass is equal to weigh force of the mass, or we can write it as [tex]F_{spring} = W_{mass}[/tex]. The reason why its the same, because the state of the system is equilibrium. That means, the spring must give the same amount of force to neutralize mass weigh force factor in opposite direction.
2. The force given by the spring to the mass when moving downward is bigger than when in equilibrium state. In equilibrium state, the force from spring only to neutralize weigh force factor from the mass. But, when the mass is moving downward because of some the force needed by spring to counter the mass force is bigger
3. The force given by the spring to the mass when moving upward is lower than when in equilibrium state. In equilibrium state, the force from spring only to neutralize weigh force factor from the mass. But, when the mass is moving upward the force is being decrease because the force that held the spring to streach to equilibrium state is getting lower.
4. The force given by the spring to the mass when moving downward is maximum. Maximum here is the force that is given by spring to mass is the highest force in its oscilation. When the mass is being strech 25cm down, the mass will oscilation up and down until it reach the equilibrium again. But it will not reach 25cm again in its oscillation because it damper force by the spring
5. The net force is the difference between force given by spring and weigh force of mass. At the top of its oscilation can be calculate by the difference of mass weight force and potensial force of spring with 25cm strecht

what is the speed of a point on the earth's surface halfway between the equator and the pole? (hint: what is the radius of the circle in which the point moves?)
The speed of the point is 463.4 miles per hour.
What is speed?
The speed of an object, also known as v in kinematics, is the size of the change in that object's position over time or even the size of the change in that object's position per unit of time, making it a scalar quantity. The instantaneous speed is indeed the upper limit of a average speed as the length of time interval approaches zero. The average speed of the object in a period of time is equal to the distance travelled by object divided by duration of the period. Velocity and speed are not the same thing.
The speed of a point on the Earth's surface halfway between the equator and the pole is equal to the circumference of the circle divided by the time it takes for the Earth to rotate once, which is 24 hours.
The circumference of a circle is equal to 2πr, where r is the radius of the circle. Since the point is halfway between the equator and the pole,
The radius is equal to half of the Earth's radius, which is approximately 3,963 miles.
Therefore, the speed of the point is equal to 2π(3,963 miles) / 24 hours = 463.4 miles per hour.

F1 = G × m₁m₂/ r²
The final force F' = G × m₁m₂/ (r/2)²
= 4G × m₁m₂/ r²
= 4F
Hence, when the distance between two objects is halved The force will increase four times.

What are the types of context clues that you can use to determine the meaning of an unfamiliar?.
Contextual hints can help in this situation. Students can use words or groups of words to identify the meaning of an unknown word in any passage by learning context clues.
Use context cues, as we frequently suggest! You should look up an uncommon word in a dictionary to confirm its definition after using context cues to discover what it means.
After considering a word's context, I would advise seeking up the word's definition in a dictionary and to ascertain its official definition, that is, its denotation or literal meaning. But as for its connotation, or whether it has a positive or negative meaning, that most likely stems from the way it is.
