What is dependent value in velocity time graphs?
A dependent value in a velocity-time graph is the velocity of the object being measured at different points in time. It is the vertical axis value that is influenced by the independent variable, time, on the horizontal axis. The dependent variable changes as a result of the independent variable.
How do you make an acceleration time graph from the data of a velocity time graph?
To create an acceleration-time graph from a velocity-time graph, you need to find the slope of the velocity-time graph at each point. The slope represents the acceleration at that specific instant. Plot these acceleration values against time to get the acceleration-time graph.
Yes, in Georgia, if you are under 21 and caught speeding 24 mph or more over the speed limit, you can face a license suspension. This falls under Georgia's Super Speeder Law, which imposes harsher penalties for excessive speeding.
What will happen if a sudden expansion is provided immediately after the throat of a venturimeter?
If a sudden expansion is provided immediately after the throat of a venturi meter, the flow velocity will decrease abruptly due to the sudden increase in cross-sectional area. This can lead to recirculation zones, pressure recovery losses, and inaccurate flow rate measurements due to disturbances in the flow profile. It is important to ensure a gradual and controlled expansion to maintain accurate measurements.
Which of these would change the direction of an object but not affect the object's speed?
Changing an object's direction without affecting speed requires a force that acts perpendicular to the object's velocity, such as centripetal force or gravitational force. This force causes the object to change direction while continuing at a constant speed. Other forces acting parallel to the object's velocity can change its speed as well as its direction.
How does kinetic energy change when the momentum is doubled?
Kinetic energy is directly proportional to the square of the momentum. Therefore, if the momentum is doubled, the kinetic energy will increase by a factor of four.
Potential energy can be converted into kinetic energy, as seen in a swinging pendulum where potential energy at the highest point is converted into kinetic energy at the lowest point.
No, average velocity is the total displacement divided by the total time taken. The slope of the tangent to the curve on a velocity-time graph at a specific instant of time gives the instantaneous velocity at that moment, not the average velocity.
Is doubling a kinetic energy source by mass bigger than when you double its speed?
Doubling the speed of an object results in a fourfold increase in kinetic energy, while doubling the mass only results in a doubling of kinetic energy. Therefore, doubling the speed will result in a bigger increase in kinetic energy compared to doubling the mass.
What is the mix ratio of Weed Hoe 108 in a 25 gal sprayer Believe you are around 7 mph?
The mix ratio of Weed Hoe 108 in a 25-gallon sprayer can vary depending on the desired concentration, target weeds, and application guidelines provided by the product. For general broadleaf weed control, a common ratio is around 1-2 ounces of Weed Hoe 108 per gallon of water. Applying at a speed of 7 mph may affect the coverage and distribution of the product, so it's important to calibrate the sprayer accordingly to ensure proper application.
What is the motion of one object around another?
In planetary terms, when referring to the motion of planets and moons etc. the motion is describes as orbiting. Moons are on orbit around planets, while the planets are in orbit around the sun. An orbital motion.
It is false. The slope of a straight line on a position-time graph is the average velocity. Slope = y2-y1/x2-x1. On a position-time graph, y is the position (d), and x is the time (t). So y2-y1 = df-di = displacement, and x2-x1 = tf-ti = time interval.
Average velocity = displacement/time interval = df-di/tf-ti
Would Kinetic energy be stronger on a tall hill or a lower hill?
The height of the hill does affect the kinetic energy directly.
The formula goes like this :
Etotal= Ekinetic energy+Egravitational potential energy
Ek= 1/2(mass)(velocity2)
and Eg= (mass)(gravitational constant 9.8)(height)
So as you get closer to the ground, the kinetic energy increases while the gravitational potential energy decreases, but the total energy remains the same throughout.
Therefore, the higher you are, the more energy you are going to gain as you travel down the hill.
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
Uniform acceleration graphs help visualize how an object's velocity changes over time. They show a constant rate of change in velocity, which can be used to calculate properties like displacement and time. Instantaneous velocity is the velocity of an object at a specific moment in time, representing the object's speed and direction at a given instant.
One kilometer is 0.621 miles. Therefore 45miles is 45/0.621 kilometers which is 72.46 kilometers. Hence 45mph is 72.46kmph
Wind turbines convert the kinetic energy of the wind into mechanical energy, which is then transformed into electrical energy. They do not convert energy directly back into potential, kinetic, or thermal energy.
How do you convert 45 miles per hour to how many feet per minute?
To convert 45 miles per hour to feet per minute, first convert miles to feet by multiplying by 5,280 (since 1 mile = 5,280 feet). Next, divide by 60 to convert hours to minutes.
45 miles/hour * 5,280 feet/mile / 60 minutes/hour = 3,960 feet/minute.
Does increasing the mass or velocity have the most affect on an object's kinetic energy?
Increasing an object's velocity has a greater effect on its kinetic energy than increasing its mass. This is because kinetic energy is directly proportional to the square of the object's velocity, while it is linearly proportional to the object's mass.
What is the speed of an object that has 7.5 joules of kinetic energy and a mass of 82 gr?
The speed of an object with 7.5 joules of kinetic energy and a mass of 82 grams can be calculated using the formula: KE = 0.5 * mass * speed^2. Rearranging the formula gives speed = sqrt(2 * KE / mass). Plugging in the values gives a speed of approximately 5.96 m/s.
Does a rock have potential and kinetic energy as it hits the ground?
When a ball is about to fall it has potential energy because of its height.
When a ball is about to hit the ground it still has some potential energy since it has't hit the ground yet, but much less than it had when it started falling.
