You push a bike pedal 10cm and the bike moves 100cm. Calculate the Speed ratio ( show all work ) ( use the formula and divide the input distance by the output distance)
Answer:
when you are pushing the pedal you are causing the pedal to move done and then you will move 100cm
Explanation:
10 cm= 100 cm moved so when you move you will move because you are timeing the 10 by 100 to get the spped
Materials that let light pass through them?
Answer:
Materials that allow most all light to pass through them are called transparent. Examples of transparent items are glass, water, and air. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper.
Answer:
They are transparent
Explanation:
Because they simple allow light to pass though instead of obstructing it

The given statement is true when you look at your speedometer and it reads 60 mph this is your instantaneous speed.
What is Speed ?In everyday language, most people use the terms speed and velocity interchangeably. In physics, however, they do not have the same meaning and are distinct concepts. One major difference is that speed has no direction; that is, speed is a scalar.
We can calculate the average speed by finding the total distance traveled divided by the elapsed time:
Average speed=Total distance=Elapsed time.
Average speed is not necessarily the same as the magnitude of the average velocity, which is found by dividing the magnitude of the total displacement by the elapsed time. For example, if a trip starts and ends at the same location, the total displacement is zero, and therefore the average velocity is zero. The average speed, however, is not zero, because the total distance traveled is greater than zero. If we take a road trip of 300 km and need to be at our destination at a certain time, then we would be interested in our average speed.
However, we can calculate the instantaneous speed from the magnitude of the instantaneous velocity:
Instantaneous speed
=|v(t)|.
If a particle is moving along the x-axis at +7.0 m/s and another particle is moving along the same axis at −7.0 m/s, they have different velocities, but both have the same speed of 7.0 m/s. Some typical speeds are shown in the following table.
We have now seen how to calculate the average velocity between two positions. However, since objects in the real world move continuously through space and time, we would like to find the velocity of an object at any single point. We can find the velocity of the object anywhere along its path by using some fundamental principles of calculus. This section gives us better insight into the physics of motion and will be useful in later chapters.

Explanation:
A spring with constant 559 N/m is 0.14 meters long when not stretched or compressed. You compress the spring until it is 0.07 meters long. How many joules of elastic potential energy are stored in the compressed spring
Answer:
1.46755 Joules
Explanation:
Applying,
E = 1/2ke²......................... Equation 1
Where E = Elastic potential energy of the spring, k = spring constant, e = extension
From the question,
Gieven: k = 559 N/m, e = (0.14-0.07) meters = 0.07 meters
Substitute these values into equation 1
E = 1/2(599×0.07²)
E = 2.9351/2
E = 1.46755 Joules

9. What would be an objects weight on Jupiter, if acceleration due to
gravity on Jupiter is 24.5 m/s/s and the object's mass is 5 kg.
Answer:
Fj / Fe = 24.5 / 9.8 acceleration on Jupiter / acceleration on Earth
Fj / Fe = 2.5
Fj / Fe = 2.5 force on Jupiter = 2.5 that on Earth
W = F = M a
W Jupiter) = 5 kg * 9.8 m/s^2 * 2.5 = 122.5 N
or more simply
F = M a = 5 kg * 24.5 m/s^2 = 2=122.5 N

Which of the following is a property of an ionic compound?
A
has a low boiling point
B
forms molecules
C
is soft and flexible
D
conducts electricity when aqueous
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

Pulling a boat forward into a docking area requires 157J of work. The boat must be pulled a distance of 5.3m. What is the force with which the boat is pulled?
Answer:
29.62 N.
Explanation:
Work = 157 J
Distance = 5.3 m
Force = ?
Work = Force * Distance
157J = Force * 5.3 m
157 J/ 5.3 m = Force
29.62 N = Force (or) Force =29.62 N
If the temperature in the past was 2.9 C higher than today what would the corresponding change in the Fahrenheit temperature have been?
Answer:
1 deg C = 5/9 deg F (Ex. 212 F - 32) * 5/9 = 100
So deg F = 9/5 deg C = 9/5 * 2.9 = 5.2 deg F

Which of these increases the kinetic energy of a car the most?
A. Doubling the mass
B. Doubling the velocity
C. They are the same
Answer:
A. Doubling the mass
Explanation:
Doubling the mass increases the kinetic energy of a car the most.
Doubling the mass increases the kinetic energy of the car.
What happens to a car when the kinetic energy is increased?The energy possessed by a body due to its motion is known as the kinetic energy.The kinetic energy completely depends upon the object's mass and velocity.The unit of kinetic energy is Joule.The formula is K.E = 1/2 mv².The unit of mass is kilogram (kg), then the unit of velocity is meter/ second. (m/s)1 Joule = 1 Kg m²/ s².
As we know the formula, Kinetic energy is equal to half of the product mass and velocity. If mass doubled then kinetic energy also gets doubled.Here, If the car was moving, there will be some kinetic energy as it has the particular mass and speed ( velocity).The kinetic energy of a car increases if the mass gets doubled.Hence, Option A is the correct answer.
