The torque exerted about the center of the disk is 0.2845Nm (rounded to 4 decimal places).
Torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study. It represents the capability of a force to produce change in the rotational motion of the body.
Moreover, torque is a twisting or turning force that tends to cause rotation around an axis, which might be a center of mass or a fixed point. Torque can also be thought of as the ability of something that is rotating, such as a gear or a shaft, to overcome turning resistance.
Therefore, torque is defined as Γ=r×F=rFsin(θ). In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F.

Answer:
t = 0.2845Nm (rounded to 4 decimal places)
Explanation:
The disk rotates at a distance of an arc length of 28cm
Arc length = radius × central angle × π/180
28cm = 10cm × central angle × π/180
Central angle = × 180/π ≈ 160.4°
Torque (t) = rFsin(central angle) , where F is the applied force
Radius in meters = 10/100 = 0.1m
t = 0.1m × 16N × sin160.4°
t = 0.2845Nm (rounded to 4 decimal places)
The three given moon phases are:
Waxing Crescent Moon
Waning Crescent Moon
Full Moon
The things we need to match to the above three topicsare:
*visible near western horizon an hour after sunset
*rises about the same time the sun sets
*visible near eastern horizon just before sun rises
*occurs about 3 days before new moon (i know this is waningcrescent)
*visible due south at midnite
*occurs 14 days after new moon (i know this is full moon)

What is the charge, in μC, on the negative one?
Answer:
The charge of the negative one is 13.27 microcoulombs and the positive one has a charge of 58.27 microcoulombs.
Explanation:
Electric potential energy between two point charges is derived from concept of Work, Work-Energy Theorem and Coulomb's Law and described by the following formula:
(1)
Where:
- Electric potential energy, measured in joules.
, - Electric charges, measured in coulombs.
- Distance between charges, measured in meters.
- Coulomb's constant, measured in kilogram-cubic meters per square second-square coulomb.
If we know that , , and , then the electric charge is:
(2)
Roots of the polynomial are found by Quadratic Formula:
,
Only the first roots offer a solution that is physically reasonable. The charge of the negative one is 13.27 microcoulombs and the positive one has a charge of 58.27 microcoulombs.
Answer:
Explanation:
Battery voltage is 6V
A current of 0.361A is draw the voltage reduces to, 5.07V
This shows that the appliances resistance that draws the currents is
Using KVL
The battery has an internal resistance r
V=Vr+Va
Vr is internal resistance voltage
Va is appliance voltage
6=5.07+Va
Va=6-5.07
Va=0.93
Using ohms law to the resistance of the appliance
Va=iR
R=Va/i
R=0.93/0.361
R=2.58ohms
Then if the circuit draws a current of 0.591A
Then the voltage across the load is
V=iR
Va=0.591×2.58
Va=1.52V
Then the voltage drop at the internal resistance is
V=Vr+Va
Vr=V-Va
Vr=6-1.52
Vr=4.48V
Answer:
V = 4.48 V
Explanation:
• As the potential difference between the battery terminals, is less than the rated value of the battery, this means that there is some loss in the internal resistance of the battery.
• We can calculate this loss, applying Ohm's law to the internal resistance, as follows:
• The value of the potential difference between the terminals of the battery, is just the voltage of the battery, minus the loss in the internal resistance, as follows:
• We can solve for rint, as follows:
• When the circuit draws from battery a current I of 0.591A, we can find the potential difference between the terminals of the battery, as follows:
• As the current draw is larger, the loss in the internal resistance will be larger too, so the potential difference between the terminals of the battery will be lower.
Answer:
They had a well-developed agricultural system , they raised domesticated animals , they developed a writing system, and they used early forms of tools.
The claim that the ancient Egyptians were primitive and relied on aliens to build their monuments is inaccurate. Evidence from archaeology and history shows that the ancient Egyptians had advanced knowledge and skills in various fields. Their construction techniques and use of mathematics in building the pyramids are well-documented.
The claim that the ancient Egyptians were primitive and that their accomplishments, such as building the pyramids, were assisted by aliens is inaccurate. There is evidence from archaeology and history that ancient monuments were built by ancient people using their own ingenuity and capabilities. The ancient Egyptians had advanced knowledge in various fields including architecture, engineering, astronomy, and mathematics. For example, their construction techniques and use of mathematics in building the pyramids and other structures are well-documented.
model and the actual car?
A: 5:1
B: 1:50
C: 50:1
D: 1:5
Answer:
it is B 1:50
Explanation:
just did it on apex
The ratio that shows the relationship between the sizes of the model car and the actual car is 1:50. This is because the actual car is 50 times longer than the model car.
The relationship between the sizes of the model car and the actual car is represented by a ratio. To find this ratio, we can divide the length of the actual car by the length of the model car. So, 6 m / 0.12 m = 50. This means that the actual car is 50 times longer than the model car, or in other words, the model car is 1/50th the size of the actual car. Therefore, the correct ratio is 1:50.
