Answer: Well it's not sinking. It is also not flooring or floating. so my guess it must be rising up.
Explanation: When something is impacted, the pressure of the force of energy is released and lands directly on a other object. So what does Jell-O do when you shake it? It wobbles right? what happens when you put your hand in a bucket of water? It makes the water rise up. So That's why I think it is rising up.
Answer:
Rising up because the weight of the object depends on the water and mass

The voltage between two points in a circuit is 4.2 V. If the resistance between
the points is 72, what is the current, according to Ohm's law?
A. 0.058 A
B. 76.2 A
O C. 17.1 A
O D. 302 A
Answers
Answer:
I = 0.058 [A]
Explanation:
Ohm's law is defined as voltage equal to the product of current by resistance.
[tex]V =I*R[/tex]
where:
V = voltage = 4.2 [V]
I = current [amp]
R = resistivity = 72 [ohm]
Now clearing I, we have:
[tex]I = V/R\\I = 4.2/72\\I = 0.058 [A][/tex]

Studying neutrinos helped to explain how our Sun works but led to changes in theories of particle physics, how is this process consistent with the scientific process? How can details about a theory be adjusted without undermining other discoveries made through the theory's predictions?
Answers
Explanation:
Yes, evidently, the process is consistent with the scientific process because in scientific process falsification and modification are two very important traits. So this new concept have modified the existing theories.
Through the modification a theory is adjusted without undermining other discovering made through the theory's prediction.
There are many other evidences that prove this fact for example Einstien's Theory of relativity also changes the existing concepts.

A 0.152 kg ball is attached to a string that is 62.2 cm long. The string will break if subjected to a tension force of 4.8 N. If a small child swings the ball in a horizontal circle around her head, at what velocity will the string break?
Answers
Answer:
The value is [tex]v = 3.68 \ m/s[/tex]
Explanation:
From the question we are told that
The mass the ball is [tex]m = 0.152 \ kg[/tex]
The length of the string is [tex]l = 62.2 \ cm = 0.622 \ m[/tex]
The tension of force that will break the string is [tex]T = 4.8 \ N[/tex]
Generally the radius of the circle made by swinging the string is [tex]r = l = 0.622\ m[/tex]
Generally the centripetal force acting on the ball is mathematically represented as
[tex]F_c = \frac{mv^2}{r}[/tex]
Generally this centripetal force is mathematically represented as
[tex]F_c = T - mg[/tex]
=> [tex]T - mg = \frac{mv^2}{r}[/tex]
=> [tex]4.8 - 0.152 * 9.8 = \frac{0.152 * v^2}{0.622}[/tex]
=> [tex]v = 3.68 \ m/s[/tex]
why is thouching the live wire of an appliane when it is connecfed to the mains dangerous
Answers
Answer: The live wire is the most dangerous one, since it is at 230 V. it should never touch the earth wire (unless the insulation is between them, of course!), because this would make a complete circuit from your mains supply to the ground (earth). A shock or fire would be highly likely.

Effect of tax on higher salaries and properties
PAYE which is an acronym for pay as you earn, is a form of tax deducted by an employer from the employee's salaries and wages.
As the person earns higher, his income tax increases, as he acquires more luxury properties, his personal tax increases as well.
Thus, the person with a new job of a much higher salary and a new car and a great stereo system for his apartment, will attract more tax.

A 1 kg puck sliding on a horizontal shuffleboard court is slowed to rest by 1 point
a frictional force of 3 N. What is the coefficient of kinetic friction between
the puck and the surface of the shuffleboard court? *
O A. 0.25
O B.0.5
O c.0.15
D. .31
Answers
Answer:
miu = 0.31
Explanation:
The friction force is defined as the product of the normal force by the coefficient of friction.
[tex]f=miu*N[/tex]
where:
f = friction force = 3 [N]
miu = friction coefficient
N = normal force [N]
The normal force on a horizontal surface can be calculated by means of the product of mass by gravity.
where:
m = mass = 1 [kg]
g = gravity acceleration = 9.81 [m/s²]
[tex]N=m*g\\N=1*9.81[/tex]
[tex]N= 9,81 [N][/tex]
Now replacing in the equation above, we can find the friction coefficient.
[tex]miu=3/9.81\\miu = 0.31[/tex]

your answer in both
km hour, and m s. (show
conversion)
IV. If the entire trip took 2.50 hours.
determine the average velocity of
the car. Give your answer in both
km h, and mph (show conversion)
Answers
Explanation:
It is given that,
A car travels 14 km due west, then does a U-turn and travels 43 km due east (when it takes U-turn, it will change direction from west to east)
i. Total distance = total path covered
= 14 km + 43 km
= 57 km
ii. Let east is positive and west is negative.
Displacement = final position-initial position
= 43-14
= 29 km
iii. If time taken in the entire trip = 3.2 hours
Average speed = distance/time
[tex]s=\dfrac{57\ km}{3.2\ h}\\\\=17.81\ km/h[/tex]
1 km/h = 0.2777 m/s
17.81 km/h = 4.94 m/s
iv. If time taken in the entire trip = 2.5 hours
Average velocity = displacement/time
[tex]v=\dfrac{29\ km}{2.5\ h}\\\\=11.6\ km/h[/tex]
1 km/h = 0.621 mph
11.6 km/h = 7.2 mph
