Hey there!
Step one: Find how many miles you can travel per day.
45(24)=1008. You could travel 1008 miles a day.
Step two: Convert 1008 miles to meters.
1008 miles roughly equals 1622219 meters.
Step three: Convert meters to Altuves.
1622/1.65=983.03 Altuves.

A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. The car has ___________energy. Calculate it.
Answer:
8.9*10^5
Explanation:
as we know that
K.E =1/2 mv²
where m is mass and v is velocity
given mass= 1120 kg
given velocity =40 m/s
so K.E=1/2 (1120)(40)²
K.E=1792000/2
K.E=896000
K.E=8.9*10^5

Fully describe or explain the solid state of matter. You should include at least 5 ways to characteristics or descriptors that prove a solid is a solid.
Answer:
Explanation:
The solid state is one of the 3 stages which matter undergoes in addition to the liquid and the gaseous state. Matter in it's solid state contains atoms which are closely packed, In this stage, matter exhibits the least amount of kinetic energy of all three stages hence hindering movement of its particles and exhibiting firmness and rigidity. Solids exhibits a regular arrangement of it's molecules which differs from the scattered nature of gaseous particles and slightly ordered nature of liquid molecules. Solids exhibits a defined volume , and shape with molecules held together by string attractive forces. Solids can change into liquid through melting or transform directly into gaseous state through sublimation.

Identify the independent, dependent, and constant variables for different experiments.
Experiment 1: A soap manufacturer runs an experiment to compare the foaming action of different dish detergents. Equal amounts of each brand of detergent are placed in identical containers half-filled with water. The water and dish detergent are at a temperature of 20°Celsius. Each container is agitated for 30 seconds, and then the height of the foam is measured.
ANSWER:
IV, Type of dish detergent. DV, height of foam. CV, type of container, amount of water in container, temperature of water, time the container is agitated.
Explanation:
Independent variable(IV)- what you change during the experiment.
dependent variable(DV)- what you're measuring during an experiment. The dependent variable is DEPENDENT because it's results DEPEND on the independent variable at play.
Constant variables(CV)- things that do not change in order to isolate the tested variables as much as possible.

Which of the following would cause a fan cart to accelerate the least?
- doubling the speed of the fan
- pointing the fan exhaust downward
- tripling the speed of the fan
- pointing the fan exhaust upward
Answer:
The correct option is;
-Pointing the fan exhaust upward
Explanation:
The fan cart transfers reaction force from the jet of air it blows through the exhaust into motion in the opposite direction of the jet. By pointing the fan exhaust upwards, the direction of motion of the cart is therefore, into the ground. Due to the solid nature of the ground the motion is resisted, and by Newton's first law of motion, a body will remain in motion unless resisted by a force. In the case of the question, the ground is resisting the motion of the cart and the cart will remain at rest and having zero acceleration.
The rotating drum in a clothes-dryer has a radius of 0.31 m. If the acceleration at the rim of the drum is 27 m/s2, what is the tangential speed of the rim?
Answer:
v = 2.89 m / s
Explanation:
This is a kinematics exercise, the centripetal acceleration is
a = v² / r
where a is the acceleration, v is the velocity and r the radius
let's clear
v = √a r
let's calculate
v = √ (27 0.31)
v = 2.89 m / s
this is the speed of the drum which is constant
The tangential speed of the rim will be "2.89 m/s".
Tangential speed:Tangential speed seems to be the rate beyond which the item moving throughout a circle travels.
A wider radius indicates that perhaps the thing goes a considerable distance.
According to the question,
Radius, r = 0.31 m
Acceleration, a = 27 m/s²
We know,
→ [tex]a = \frac{v^2}{r}[/tex]
or,
→ [tex]v= \sqrt{ar}[/tex]
By substituting the values,
[tex]= \sqrt{27\times 0.31}[/tex]
[tex]= 2.89 \ m/s[/tex]
Thus the answer above is right.

A penny has a mass of 2.5 grams. It is laying on level ground. What is the normal force acting on the penny?
Answer:
0.0245 N
Explanation:
Given that a penny has a mass of 2.5 grams. Convert the gram to kilogram by dividing it by 1000
2.5/1000 = 0.0025kg
It is also given that it is laying on level ground.
The normal force will be directly opposite direction to the weight of the penny. Which will be of equal magnitude.
What is the normal force acting on the penny ?
Normal force = weight of the penny
Weight = mg
Where g = 9.8 m/s^2
Weight = 0.0025 × 9.8
Weight = 0.0245 N
Therefore, the Norma force = 0.0245N
Which fact was most likely discovered between the time of Mendeleev’s table and the time of Moseley’s table that helped Moseley develop his version?
Answer:
The number of protons in an atom is different than the atom's total mass.
Explanation:
Mendeleev had presented the first structured periodic table in 1869. But, in 1913, Henry Moseley developed the modern periodic table. The crucial difference between the two periodic tables is that Mendeleev's periodic table is generated on the basis of the atomic masses of chemical elements while the chemical element's atomic numbers were the main focus of Moseley's periodic table. There were just 56 chemical elements in Mendeleev's periodic table. On the other hand, 74 chemical elements are presented in Moseley's periodic table.
Answer:
it is
Explanation:
The correct option is THE NUMBER OF PROTONS IN AN ATOM IS DIFFERENT FROM THE ATOM'S TOTAL MASS.
During the time Mendeleev developed his periodic table, scientists believed that the number of protons in an atom determine the mass of that atom. But withing the forty years that separated Mendeleev periodic table from Moseley periodic table it was found out that this was not so, this fact helped Moseley in his own work.
A steam engine generating 5 hp is raising a load weighing 2000 lb.How high will thebload be raised in 10 s.
Answer:
Explanation:
bi
The height raised by the load is 4.18 m.
Given data:
The power rating of steam Engine is, P = 5 hp = 5 × 745.7 = 3728.5 W.
The weight of load is, W' = 2000 lb = 2000 × 4.45 = 8900 N.
The time interval is, t = 10 s.
We know that the rate of doing any work is known as Power. So here the power will be equal to the work done to raise the load for 10 s of time. Then the expression is,
[tex]P = \dfrac{W}{t}\\\\P = \dfrac{W' \times h}{t}[/tex]
Here, h is the height raised by load.
Solving as,
[tex]3728.5 = \dfrac{8900 \times h}{10}\\\\h = 4.18 \;\rm m[/tex]
Thus, we can conclude that the height raised by the load is 4.18 m.

The volume of gas in a flexible container at a depth of 10 m/33 ft will expand to ______ its original volume if taken to the surface.
Answer:
Twice its original volume.
Explanation:
For diving applications, 10 m/33 feet of sea water is taken to exerts a gauge pressure that is the same pressure as the atmosphere, or one ata/bar.
This means that we add one ata/bar pressure for every 10 m/33 feet you descend.
The effect of this is that, at 10 m/33 ft, you're under an absolute pressure of two ata/bar, one from air and one from water. Adding another 10 m/33 ft to this depth to make it 20 m/66 ft, puts you under under three ata/bar of pressure and so on.
Descending to a depth of 10 m/33 ft, with a flexible container means that you have double the ata/bar pressure acting on you. If you decide to resurface, the pressure on the flexible container will reduce by a factor of two.
Since volume is inversely proportional to the pressure, if the pressure reduces by a factor of 2, then the volume will increase by a factor of two, or we can say that the volume will double.

Why is publishing results important in science?
O A. It adds bias to experimental data.
O B. It turns hypotheses into scientific laws.
O C. It lets scientists show off their imaginations.
O D. It allows others to evaluate the results.
Answer:
D. It allows others to evaluate the results.
Explanation:
All the scientists prefer publishing of their research so that scientific and medical community can evaluate the results.
The published research provides instructions or information that allows other researchers to repet the experiment and verify the results. All the scientific publications are based on research and observation which helps other reserachers to refer the published research to find something new.
Hence, the correct answer is "D".
