A certain resistance thermometer reads 14. 5 Ω in pure melting ice and 18. 5 Ω in steam at standard atmospheric pressure. What will be its resistance at room temperature of 27. 0 o C ?
The resistance of the thermometer at the given temperature is 15.58 ohms.
Resistance of the thermometer
The resistance of the thermometer can be determined by applying method of interpolation as shown below;
[tex]\frac{R_\theta - R_0}{R_{100} - R_0} = \frac{\theta -0}{100 - 0}[/tex]
where;
Rθ is the resistance of the thermometer at 27⁰CR100 is the resistance at steam temperatureR0 is the ice temperature[tex]\\\\\frac{R_\theta - 14.5}{18.5 - 14.5} = \frac{27}{100} \\\\\frac{R_\theta - 14.5}{4} = \frac{27}{100}\\\\100R_\theta - 1450 = 108\\\\100R_\theta = 1558\\\\R_\theta = 15.58 \ ohms[/tex]
Thus, the resistance of the thermometer at the given temperature is 15.58 ohms.

Using the velocity versus time graph, what was the average acceleration of the object during segment B?
a) 0 m/s/s
b)20 ms/s
c) 10 m/s/s
d) 5 m/s/s
Answer:
the answer is B 20 ms/s
Explanation:
N/A
Thus the for the given velocity versus time graph the average acceleration of the object during segment B is 0 m/s/s.Hence, option A is the correct option.
Average acceleration- Acceleration is defined as the rate of change of acceleration. Average acceleration for an interval can be defined as the rate of change of velocity for that interval per time.
Let [tex]\Delta v[/tex] be the change in velocity and [tex]\Delta t[/tex] be the change in time in a given time interval. Then average acceleration is,
[tex]a= \dfrac{\Delta v}{\Delta t}[/tex]
At segment B, It starts at 4.5 seconds and ends at 10 seconds. The total time interval for this segment is 5.5 seconds.Therefore,
[tex]\Delta t=5.5[/tex]
Now the change in velocity for segment B. In segment B the velocity does not change at any point and keeps the value of 20 m/sec at the time interval.
According to the definition of the average acceleration when an object is changing its velocity (whether by a constant amount or a varying amount) then it is an accelerating object. And an object with a constant velocity is not accelerating.
Thus the for the given velocity versus time graph the average acceleration of the object during segment B is 0 m/s/s.Hence, option A is the correct option.

An air track car with a mass of 5-kg and velocity of 2 m/s to the right collides with a 3-kg car moving to the left with a velocity of 3 m/s. After the collision, the two cars bounce off of each other and the 5-kg car bounces back with a velocity of 1 m/s. What is the new velocity of the 3-kg car after the collision?
Answer: 2 m/s to the right
Explanation:
This is a conservation of momentum question:
p before = p after → m1v1 + m2v2 = m3v3 + m4v4
**Note- if the speed is to the left, plug in a negative v!
5(2) + 3(-3) = 5(-1) + 3(v4) → 1 = -5 + 3v4 → v4 = +2 m/s :)
Explain how you would figure out ifc=4 is a solution to c + 5 = 13.
Answer:
Simple, plug 4 into c.
4 + 5 = 13
Is this true, no. So therefore c is not equal to 4.

a) the actual mechanical advantage
b) the velocity ratio
c) the length of the slope if the height of the slope is 10 m
The actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is mathematically given as
A=20VR=0.05x=20mWhat are the actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is 10 m?Question Parameters:
A block of weight 5000 N is pushed up a slope by a force of 250 N.
Generally, the equation for the actual mechanical advantage is mathematically given as
A=Fout/Fin
A=5000/250
A=20
b)
the velocity ratio is given by the distance moved by the effort divided by the distance moved by the load
Therefore
VR=250/5000
VR=0.05

Explanation:
1.What is light?
2.How light is being measured?
3.How light is being produced naturally and artificially?
4.How light is being detected?
5.What is the difference between light and ambient?
6.What are the modes of light sensors? Explain each.
Answer:
1. light is electromagnetic radiation within the portion of electromagnetic spectrum that is perceived by the human eye.
2. it's measured in footcandles or lux- it is the amount of light (lumens) falling on a Surface (over any given square foot or square meter). therefore, light intensity is measured in terms of lumens per square foot (footcandles) or lumens per square meter (lux).
3. natural light,, which produces heat and color comes from the radiation given off by the sun. It is then filtered through the Earth's atmosphere and absorbed by plants. Artificial light sources can consist of a filament that uses electricity or halogen gas to go or an electronic device that emits light.
4. most of our conscious vision stem from photoreceptors in the retina, the light-sensitive layer at the back of our eyeball. In animals with backbones (vertebrates) cells that detect light for vision are vaguely shaped like rods or cones giving them their familiar names.
5. there is a difference between ambient and task lighting. task lighting provides focus light so you can see better perform a certain task. while ambient fixtures offer general lighting for your home, distribute light evenly as well as helps create a mood.

There are 2 cars that are getting ready to race. After sitting at a stoplight for 30 seconds, the light turns green and they begin to accelerate at a rate of 4m/s2. The cars were neck and neck the whole way after traveling 150 meters. How long did it take them to travel that 150 meters?
Answer:
75secondsExplanation:
Given that the acceleration of the car is
a=4m/s^2
and also the distance covered is
d=150m
from the problem "The cars were neck and neck the whole way after traveling 150 meters"
this means velocity was constant throughout
s=ut+1/2at
150=0*t+4t/2
150=2t
divide both sides by 2
t=150/2
t=75seconds
