In your own words, explain why seconds are derived from an actual value and not an arbitrary one.
Answer:
Second is a unit for measuring time. As the scientist usually wants precision, is needed that the units are well defined and that the unit is exactly the same for everyone.
So, if for example, (and for some weird reason) you do not have access to a precise clock to measure one second, you can use the actual value (by definition) of the second to find the exact length of a second.
So, resuming is used for consistency.
We have that The second was derive from a number that is
[tex]\frac{1}{86400}[/tex] of a solar day(24hours)
it is important to note that the seconds was discovered or established before clocks
Now, seconds are derived from an actual value and not an arbitrary one.
The second was derive from a number that is [tex]\frac{1}{86400}[/tex] of a solar day(24hours)
The second was designed to make the its value as close as possible to this number in the modern day seconds

A particle makes 240 revolution per minutes on a circular radius of 2m find: (I) it's period (ii) it's angular velocity (III) it's linear velocity and (iv) it's acceleration
Answer:
(i) The period is 0.25 seconds, (ii) The angular velocity is approximately 25.133 radians per second, (iii) The linear velocity of the particle is approximately 50.266 meters per second, (iv) The acceleration experimented by the particle is approximately 1263.336 meters per square second.
Explanation:
(i) Let suppose that particle experiments an uniform circular motion. The period ([tex]T[/tex]) of the particle, measured in seconds, is the time needed to complete a revolution, which is determined by this:
[tex]T = \frac{2\pi}{\omega}[/tex]
Where [tex]\omega[/tex] is the angular speed, measured in radians per second.
Let is convert angular speed from revolutions per minute into radians per second:
[tex]\omega = \left(240\,\frac{rev}{min} \right)\times \left(\frac{1}{60}\,\frac{min}{s} \right)\times \left(2\pi\,\frac{rad}{rev} \right)[/tex]
[tex]\omega \approx 25.133\,\frac{rad}{s}[/tex]
The period of the particle is:
[tex]T = \frac{2\pi}{25.133\,\frac{rad}{s} }[/tex]
[tex]T \approx 0.25\,s[/tex]
The period is 0.25 seconds.
(ii) The angular velocity is approximately 25.133 radians per second.
(iii) The linear velocity of the particle ([tex]v[/tex]), measured in meters per second, is found by this expression:
[tex]v = R\cdot \omega[/tex]
Where:
[tex]R[/tex] - Radius, measured in meters.
[tex]\omega[/tex] - Angular velocity, measured in radians per second.
If [tex]R = 2\,m[/tex] and [tex]\omega \approx 25.133\,\frac{rad}{s}[/tex], the linear velocity of the particle is:
[tex]v = (2\,m)\cdot \left(25.133\,\frac{rad}{s} \right)[/tex]
[tex]v \approx 50.266\,\frac{m}{s}[/tex]
The linear velocity of the particle is approximately 50.266 meters per second.
(iv) As particle rotates at constant speed, resultant acceleration ([tex]a[/tex]) is entirely radial and modelled by this expression:
[tex]a = \omega^{2}\cdot R[/tex]
[tex]a = \left(25.133\,\frac{rad}{s} \right)^{2}\cdot (2\,m)[/tex]
[tex]a \approx 1263.336\,\frac{m}{s^{2}}[/tex]
The acceleration experimented by the particle is approximately 1263.336 meters per square second.
Express the answer to 4.31x10^7 multiplied by 5.41x10^5 scientific notation.
Answer:
The product of the two numbers is 2.33* 10^13
Explanation:
Given
4.31x10⁷ and 5.41x10⁵
Required
Multiply
The multiplication of the two digits is represented as thus:
[tex]Result = 4.31 * 10^7 * 5.41 * 10^5[/tex]
This can also be rewritten as
[tex]Result = 4.31 * 5.41 * 10^7 * 10^5[/tex]
Multiply 4.31 and 5.41
[tex]Result = 23.3171 * 10^7 * 10^5[/tex]
Apply laws of indices
[tex]Result = 23.3171 * 10^{7+5}[/tex]
[tex]Result = 23.3171 * 10^{12}[/tex]
The scientific notation is always in the form: [tex]a * 10^n[/tex]
Where [tex]1 \leq\ a \leq 10[/tex]
So:
23.3171 can be rewritten as 2.33171 * 10
So, we have:
[tex]Result = 2.33171 * 10* 10^{12}[/tex]
Also, apply law of indices again
[tex]Result = 2.33171 * 10^{1+12}[/tex]
[tex]Result = 2.33171 * 10^{13}[/tex]
It's always advisable (but not compulsory to approximate to 1 or 2 decimal places)
So:
[tex]Result = 2.33* 10^{13}[/tex]
Hence; the product of the two numbers is 2.33* 10^13

Technician A says that work is being performed if a force is being applied, yet the object does not move. Technician B says that torque is a twisting force that may or may not result in motion. Which technician is correct
Answer:
Technician B is correctExplanation:
According to technician B "torque is a twisting force that may or may not result in motion" which is right, but technician A is wrong in the sence that for work to be done the force must be applied over a distance that is there must be movement over a distance.
What is work?
work is the application of force over a distance
mathematically
work= force* distance
and it is measured in joules
What is torque?
Torque is a measure of the force that can cause an object to rotate about an axis(hence it is very possible that the object maintained its position)

The force of gravity pulls down on your school with a total force of 400,000 newtons. The force of gravity pulling down on your school would be exactly twice as much if your school: a Had twice as much mass b Was twice as tall c Had twice as much volume d Covered twice as much area pleaseeee help
Answer:
A
Explanation:
Force of gravity can be expressed as:
F = GMM/R^2
Where
F = gravitational force
M = mass
R = distance
Also, W = mg
From the above equation, we can deduce that force of gravity actually depends on mass and not volume.
The correct answer is therefore A.
Had twice as much mass
Therefore, the force of gravity pulls down on your school with a total force of 400,000 newtons. The force of gravity pulling down on your school would be exactly twice as much if your school Had twice as much mass

Explanation: I do not know much about this but the answer that i think it is was b.
A rock turns a reddish color when exposed to air and water. this description is evidence of chemical weathering
Chemical weathering is demonstrated by the fact that "a rock turns a reddish colour when exposed to air and water." The breakdown of rocks occurs through a process known as chemical weathering, which involves chemical interactions with elements including water, oxygen, and acids. The iron in the rock may have oxidised, which is when iron in the rock combines with oxygen and water to generate iron oxide (rust), giving the material its reddish hue. The physical weathering produced by wind-borne particles is described in Option A, the physical weathering induced by freeze-thaw cycles is described in Option B, and the physical weathering caused by gravity and the impact of the rock striking the ground is described in Option D.
Hence option C is correct.
