The correct answer is D. There is no direct relationship between the opening temperature of the limit switch and the melting temperature of a fusible link.
A limit switch and a fusible link are two different components used in various systems, such as safety mechanisms in machinery or fire suppression systems. They serve different purposes and operate based on different principles.
A limit switch is an electrical switch that is activated or deactivated based on the physical position or presence of an object. It typically has a predetermined temperature at which it opens or closes, but this temperature is not related to the melting temperature of a fusible link.
On the other hand, a fusible link is a safety device designed to melt or break when exposed to high temperatures. It acts as a fire protection measure by providing a fail-safe mechanism. The melting temperature of a fusible link is specific to its design and materials and is not directly related to the opening temperature of a limit switch.
Therefore, there is no direct relationship between the opening temperature of a limit switch and the melting temperature of a fusible link.

What is the mass and density of 237 mL of water
Answer:
V(water)= 237 mL=237×10^-6 m^3ρ(water)=1000 kg/m^3m=ρ×V=(1000)×(237×10^-6)m= 237×10^-3 = 0.237 kgm= 237 gram.Calculate the mass (in g) of 0.8 cm³ of steel. The density of steel is 7.8 g/cm³. Give your answer to 2 decimal places.
mass= density times volume so 7.8 g/cm3 by0.8 cm3 answer is 6.24 g and it's already in two decimal places
Answer:
[tex]\boxed{6.24g}[/tex]
Explanation:
→ Utilise the density formula
Density = Mass ÷ Volume
→ Rearrange to make mass the subject
Mass = Density × Volume
→ Identify the density and volume values
Density = 7.8 and Volume = 0.8
→ Substitute the values into the density equation
Mass = 7.8 × 0.8 = 6.24 g

You pull a sled with a package on it across a snow-covered flat lawn. If you
apply a force of 46.8 N to the sled, it accelerates at 0.75 m/s2. What is the
combined mass of the package and the sled? (Assume there is no friction.)
A. 62.40 kg
B. 52.50 kg
C. 96.75 kg
D. 35.10 kg
Answer:
m = 62.4 kg
Explanation:
The force applied to the sled, F = 46.8 N
Acceleration of the sled, a = 0.75 m/s²
We need to find the combined mass of the package and the sled. Let it is m. Using definition of force as follows :
F = ma
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{46.8}{0.75}\\\\m=62.4\ kg[/tex]
So, the mass of the package and the sled is 62.4 kg.

Explanation:
how is sound wave produced?
Answer:
Sound is produced when an object vibrates, creating a pressure wave.
Explanation:
This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. ... The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
Answer:
A sound wave is created by continuous vibration of an object. We hear sound when these waves created by vibrations reach our eardrum.

Q#1 A car is observed traveling 133 m in 4.5 seconds. (Show work)
A) What is its Velocity in m/s?
B) How long would it take this car to travel 3500m?
Answer:
A) 25.56 m/s (I rounded because it was repeating)
B) 118.40 seconds
Explanation:
To calculate speed/velocity, you divide distance by time so you would do 133/4.5=25.5556
Then, to calculate the time, you divide distance by speed/velocity, so 3500/25.56=118.403

Formulating a Hypothesis
Write a hypothesis about the effect of the fan speed on
the acceleration of the cart. Use the "if then

question: "How does an object's position and velocity
change as the object accelerates?"
Answer:
If the fan speed increases, then the acceleration increases because a greater fan speed supplies more energy to move the cart.

A scientist conducting a field investigation records measurements of very low pressure and high relative humidity at the top of a mountain. A weather map indicates that a warm front is approaching the mountain. Which condition would the scientist most likely observe at the top of the mountain?
Answer:
Please find the answer in the explanation
Explanation:
Given that a scientist conducting a field investigation records measurements of very low pressure and high relative humidity at the top of a mountain.
Since a weather map indicates that a warm front is approaching the mountain, according to the conventional current, the warm front is approaching because the weather must have been in higher relative humidity in cool air.
The warm front is approaching to replace it so that the cool air can conventionally replace the warmth air too.
The condition the scientists will most likely observe at the top of the mountain will be high relative humidity.

What mass of silver will occupy a volume of 87.75 mL?
The density of silver is 10.49 g/mL.
Answer:
The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.
Explanation:
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
So the density of silver is 10.49 g / mL indicates that 10.49 g occupies a volume of 1 mL. Then a rule of three can be applied in the following way: if in 1 mL a mass of 10.49 g is occupied, in 87.75 mL how much mass will it occupy?
[tex]mass=\frac{87.75 mL*10.49 g}{1 mL}[/tex]
mass= 920.5 g
The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.
A scooter traveling at 4 m/s rides 800 meters. For what duration of time has the scooter been traveling?
Answer:
The answer is 200 sExplanation:
To find the duration or time taken we use the formula
[tex]t = \frac{d}{v} \\ [/tex]
where
d is the distance
v is the velocity
From the question
d = 800 m
t = 4 m/s
We have
[tex]t = \frac{800}{4} \\ [/tex]
We have the final answer as
200 sHope this helps you
200secs
The equation is Distance ÷ speed = time so, 800m ÷ 4m/s = 200 secs.
Astronomers observe a spectral analysis of a distant star where a particular element has a spectral line with a wavelength of 663 nm. In the laboratory, the same element has a spectral line with a wavelength of 645 nm.
a. How fast is the star moving, and in what direction is it moving?
b. The same element on Earth’s surface is observed from a space shuttle orbiting at 7800 m/s,
350 km above Earth. Is the same shift in the spectral line seen from the space shuttle? Why or why not?
Answer:
(a). The velocity of star is [tex]8.1\times10^{6}\ m/s[/tex] and the direction of star toward the earth.
(b). The shift is 0.0168 nm.
Explanation:
Given that,
Wavelength of spectral line = 663 nm
Wavelength of spectral line in lab = 645 nm
(a). We need to calculate the velocity
Using doppler's effect
[tex]\Delta \lambda=\dfrac{v}{c}\lambda[/tex]
Where, [tex]\Delta\lambda[/tex]= change in wavelength
v = velocity
c = speed of light
Put the value into the formula
[tex]663-645=\dfrac{v}{3\times10^{8}}\times663[/tex]
[tex]v=\dfrac{3\times10^{8}(663-645)}{663}[/tex]
[tex]v=8144796.38\ m/s[/tex]
[tex]v=8.1\times10^{6}\ m/s[/tex]
The direction of star toward the earth.
(b). Speed = 7800 m/s
We need to calculate the shift
Using formula of shift
[tex]\Delta \lambda=\lambda(\sqrt{\dfrac{1+\dfrac{v}{c}}{1-\dfrac{v}{c}}}-1)[/tex]
Put the value into the formula
[tex]\Delta \lambda=645\times(\sqrt{\dfrac{1+\dfrac{7800}{3\times10^{8}}}{1-\dfrac{7800}{3\times10^{8}}}}-1)[/tex]
[tex]\Delta\lambda=0.0168\ nm[/tex]
This shift is small compare to the the movement of Earth around the sun.
Hence, (a). The velocity of star is [tex]8.1\times10^{6}\ m/s[/tex] and the direction of star toward the earth.
(b). The shift is 0.0168 nm.
