A thermometer visualization is often used to represent progress towards a goal, target, or limit.
A thermometer typically a vertical bar or column that resembles a thermometer, with a scale indicating the range of values.
As you mentioned, you are considering replacing a gauge with a thermometer for your visualizations.
The values that you would have when using a thermometer visualization would include:
Current Value: This is the data point you are tracking or measuring. It could be anything that you want to represent visually, such as sales, progress, temperature, etc.
Target or Goal: The value you are aiming to achieve. This represents the desired end point of your progress or measurement.
Maximum Value: The upper limit of the thermometer's scale. This could represent the maximum value that is possible or feasible for your data.
Minimum Value: The lower limit of the thermometer's scale. This sets the starting point for your visualization.
Scale Increments: The divisions on the thermometer that indicate different levels of progress. These could be marked with specific values or simply represent proportional divisions.
Units: The units in which your data is measured. For example, if you're tracking sales, the units could be dollars, while for temperature, it could be degrees Celsius or Fahrenheit.

Two point charges of 20. 0 μc and -8. 00 μc are separated by a distance of 20. 0 cm. what is the intensity of electric field e midway between these two charges? group of answer choices
The intensity of electric field E midway between these two charges is 2.52*10^7N/C.
To find the answer, we have to know more about the electric field.
How to find the electric field?We have the expression for net electric field as,[tex]E=\frac{kQ}{r^2}[/tex]
where, k is the constant equal to 8.99*10^9.
Thus, we can write the electric field created by 20micro coulomb charge at the midway between two charges is,[tex]E_1=\frac{8.99*10^9*20*10^{-6}}{10*10^{-2}} =1.79*10^7N/C[/tex]
We can write the electric field created by -8micro coulomb charge at the midway between two charges is,[tex]E_2=\frac{8.99*10^9*8*10^{-6}}{(10*10^{-2})^2} =7.19*10^6N/C[/tex]
Thus, the net field at the midway due to two charges will be,[tex]E=1.79*10^7+7.19*10^6=2.52*10^7N/C[/tex]
Thus, we can conclude that, the intensity of electric field e midway between these two charges is 2.52*10^7N/C.

A blue train of mass 50 kg moves at 4 m/s toward a green train of 30 kg
initially at rest. The trains collide. After the collision the green train moves with a speed of 3 m/s. What is the final momentum of the blue train?
A. 90 kgm/s
B. 200 kgm/s
C. 110 kgm/s
D. 20 kgm/s
Answer:
C
Explanation:
Use conservation of momentum
Momentum before collision = mv = 50 (4) = 200 kg-m/s
AFTER collision
30 * 3 + Blue momentum = 200

120kJ work is generated by a healthy adult who circulates 9L of blood through the brachial artery in 10 min.
What is mean by work?Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. It is frequently described in its most basic form as the result of force and displacement.Calculation of Work generatedA flow rate of 900 mL per minute is equal to a flow of 9 L in 10 minutes.
Additionally, you have 200W of total power generated.
9L Equals 9000 mL
900mL/min x 9,000mL/10min
By multiplying the power (watt) by the time, we can derive the work performed by the adult.

Given data,
Mass of glider A (M[tex]_{1}[/tex]) = 0.15 kg

Approximating the eye as a single thin lens 2. 70 cm from the retina, find the focal length of the eye when it is focused on an object at a distance of 265 cm?
The focal Length of the eye is 0.37cm.
The retina, which is always 2.70 cm away from the lens, serves as the image's primary imaging medium. Image distance is 2.70 cm as a result.
The object is located 265 cm away from the eye's lens.
Based on lens formula:
[tex]\frac{1}{f} = \frac{1}{u} + \frac{1}{v}[/tex]
where the object distance is u, the image distance is v, and the focal length is f.
Consequently, u is 265.00 cm and v is 2.70 cm.
[tex]\frac{1}{f} = \frac{1}{265} + \frac{27}{10}[/tex]
[tex]\frac{1}{f} = \frac{7165}{2650}[/tex]

Frictional forceAn opposing force to the relative motion of two bodies in contact is known as frictional force. Always acting in the opposite direction from the direction of motion, frictional force is applied to a moving body. Because it resists motion, it aids in lowering the moving object's speed. The force is one of touch. Four broad categories can be made for the force of friction depending on the sort of motion that occurs between the two objects. Static friction is the force of friction between an object and the surface it is put on.

(Repost) I need help with this physics question. Thanks in advance! Answer ASAP.
(a) The gravitational force received by each 1 kg mass is 8.66 N.
(b) The magnitude of gravitational acceleration is 8.66 m/s².
(c) The orbital speed of the ISS is 7,663.6 m/s.
(d) The time take for the ISS to orbit round the Earth is 5,558.75 seconds which is equal to 1.54 hours.
Gravitational force received by each 1 kg massThe gravitational force received by each 1 kg mass is calculated as follows;
F = Gm₁m₂/r²
where;
m₁ is mass of Earthm₂ is mass of ISSr is the distance between the ISS and center of EarthF = (6.67 x 10⁻¹¹ x 5.97 x 10²⁴ x 1) / (6780,000)²
F = 8.66 N
Magnitude of gravitational accelerationmg = GMm/r²
g = GM/r²
where;
M is mass of Earthg = (6.67 x 10⁻¹¹ x 5.97 x 10²⁴ ) / (6780,000)²
g = 8.66 m/s²
Orbital Speed of the ISSv = √GM/r
v = √(6.67 x 10⁻¹¹ x 5.97 x 10²⁴ / 6780,000)
v = 7,663.6 m/s
Time of motion of the ISS round the EarthT = 2πr/v
T = (2π x 6780,000) / (7663.6)
T = 5,558.75 seconds
1 hour = 3600 seconds
= 5,558.75/3600
= 1.54 hours
Thus, the gravitational force received by each 1 kg mass is 8.66 N.
The magnitude of gravitational acceleration is 8.66 m/s².
The orbital speed of the ISS is 7,663.6 m/s.
The time take for the ISS to orbit round the Earth is 5,558.75 s = 1.54 hours.

Please help, I don't understand lol
The resulting velocity of marble B after the collision is 2.4 m/s.
The object with the faster velocity, and thus larger momentum, will impart more energy to the slower object during the collision than vice versa. Following the collision, the object with the lower beginning velocity will travel away from the other object with a higher speed and momentum.
Marble A's mass, marble B's mass, marble B's initial velocity, marble A's final velocity, marble B's final velocity, and marbles A and B's combined mass and initial velocity
Applying the mass-conservation principle
Momentum is conserved.
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(0.08 kg)(0.5 m/s) + (0.05 kg)(0 m/s) = (0.08 kg)(-0.1 m/s) + (0.05 kg) v
0.04 kg m/s = -0.08 kg m/s + (0.05 kg) v
0.12 kg m/s = (0.05 kg) v
v = 2.4 m/s
