Steve is recording the temperature of an object on Celsius and Fahrenheit scales. Relationship between the two scales is given by F = 1.8 ⋅ C. Steve will plot the Celsius readings along the y-axis and the Fahrenheit readings along the x-axis. (5 points) True False
Answer:
False
Explanation:
since the Farenheit depends on the amount of Celsius times (*) 1.8 (F= 1.8 * C),
then we can deduce that Farenheit is the dependent variable while celsius is independent. after this, remember that the independent variable is the X value and the dependent variable is the Y value.

Explanation:
Let's assume the 1D is along x - axis.
Then, the object can move in two directions, along +x axis or - x axis, depending upon reference point .
Yes, it can be still, speed up and slow down.
a woman drops a rock from a bridge to the water 17.5 m below. with what speed does the rock strike the water?
a. 0 m/s
b. 18.5 m/s
c. 171m/s
d. 9.8 m/s
e. 17.5 m/s
Given :
Height from which rock is dropped, h = 17.5 m.
Initial velocity, u = 0 m/s.
To Find :
Speed does the rock strike the water.
Solution :
We know, by equation of motion :
[tex]v^2-u^2=2as[/tex] ......( 1 )
Here , a = g = 9.8 m/s² ( Acceleration due to gravity )
Putting all given values in 1 , we get :
[tex]v^2-u^2=2as\\\\v=\sqrt{2gh}\\\\v=\sqrt{2\times 9.8\times 17.5}\ m/s\\\\v=18.5\ m/s[/tex]
Therefore, speed with rock strike the water is 18.5 m/s.
Hence, this is the required solution.

Explanation:
The density of water is 1.00 g/mL. This means if a rock has a density of 0.87 g/mL, it will ____in water.
a) float
b) sink
Answer:
Float
Explanation:
It is given that,
The density of water is 1 g/mL
The density of a rock is 0.87 g/mL
It can be seen that the density of water is more than that of rock. The density of an object is calculated from its mass and volume.
If the density of liquid in which it is placed, is more that that of the object, it will float at the top.
Hence, in this case the rock will float.
Determine how many Altuves you could travel in a day if you were moving at 45.000 mph all day. Altuve = 1.65 m
Answer:
The answer is below
Explanation:
Speed is the ratio of total distance traveled to the total time taken. It is given by the formula:
Speed = Distance / time taken
Given that the speed = The polynomial 45.000 mph.
In a day there are 24 hours, hence, the distance traveled is:
Speed = Distance / time taken
45 mph = Distance / 24 hours
Distance = 45 mph × 24 h = 1080 miles
But 1 mile = 1609.34 m
1080 miles = [tex]1080\ miles*\frac{1609.34 \ m}{1\ miles}=1738092\ m[/tex]
Given that Altuve = 1.65 m
Hence, the number of Altuve traveled = 1738092 m / 1.65 m = 1053389
1053389 Altuves was traveled

Answer:
D. Making improvements to the original prototype in order to perform
more tests
Explanation:
just did it
The one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.
What is prototype?Prototype is defined as a type of early version, or initial release of a product created to test a theory or procedure.
It can be defined as a test procedure where design teams put concepts into concrete forms, whether they be paper or digital.
It can also be defined as a useful tool for the creation of new products. It provides the creative with the opportunity to watch their concept come to fruition.
There are three basic rule of prototyping.
Inquire as to who will gain.Fail frequently and early.Use show and ask instead of show and tell.When the EGL system code does not have access to the function itself, a function prototype definition is used to provide type checking on function calls.
Thus, the one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

1. How should Rick correct his technique?
2. Are these students behaving appropriately? If not, what should they
be doing differently?
the guy on the left is rick , the girl in the middle is sarah, and the guy on the right is Andrew.
Answer:
1) Rick should be taking and gathering the gas with his hand towards his face gently to get just a whiff.
2) These students are doing the complete opposite of what should properly be done. Andrew shouldn't be drinking any chemicals that don't belong in his body. Sarah shouldn't be throwing whatever chemicals into a mixture, this can cause a lot of possible danger. Rick shouldn't be directly smelling the gas which can also be harmful. Rick needs to be wearing gloves and smell the gas in a proper way. Sarah should wear goggles and pay attention to what she is mixing. Andrew should be wearing gloves and goggles and shouldn't be drinking the chemical.
A car was traveling at a velocity of 8 m/s and then accelerated at a rate of 5 m/sr^2, reaching a velocity of 85 m/s. How far did the car travel at this acceleration rate?
Answer:
716.1 m
Explanation:
A car was travelling at a velocity of 8m/s
It accelerated at 5m/s^2
It finally reached a velocity of 85m/s
The distance can be calculated by applying the fourth equation of motion
V^2= U^2 +2as
V= 85m/s
U= 8m/s
a= 5m/s^2
85^2= 8^2 + 2(5)(s)
7225= 64 + 10s
7225-64= 10s
7161=10s
s= 7161/10
= 716.1 m
Hence the car travelled at a distance of 716.1 m
On what factors does the quantity of heat of an object depend?
Explanation:
This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.
A ball is thrown straight up. If the launch velocity is 15 m/s, at what SPEED will the ball return to the thrower’s hand?
a) -15 m/s
b) -9.8 m/s
c) 15 m/s
d) 0 m/s
Answer:
Vf = 15 m/s
Explanation:
First we consider the upward motion of ball to find the height reached by the ball. Using 3rd equation of motion:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = -9.8 m/s² (negative sign for upward motion)
h = height =?
Vf = Final Velocity = 0 m/s (Since, ball momentarily stops at highest point)
Vi = Initial Velocity = 15 m/s
Therefore,
2(-9.8 m/s²)h = (0 m/s)² - (15 m/s)²
h = (-225 m²/s²)/(-19.6 m/s²)
h = 11.47 m
Now, we consider downward motion:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height = 11.47 m
Vf = Final Velocity = ?
Vi = Initial Velocity = 0 m/s
Therefore,
2(9.8 m/s²)(11.47 m) = Vf² - (0 m/s)²
Vf = √(224.812 m²/s²)
Vf = 15 m/s
Which property of an object is the result of gravity?
O A. Weight
B. Mass
O C. Velocity
OD. Volume
Answer:
it's (A) weight I think
Answer:
A. Weight
Explanation: Weight is defined as the amount of force placed on an object from gravity which means it is directly reliant on the force of gravity while the other choices are not. Neither Mass, volume, or velocity is impacted by gravity as much as weight, velocity is the direction of speed, mass is the resistance that a body of matter offers to a change in its speed or position upon the application of a force, and volume is the amount of space an object takes. As you can see none of these componant have gravity as a determining factor other than weight since weight is determined by the gravity which is why the weight of an object can vary if your on earth or on the moon since the gravity is different.
