A physics teacher performed a demonstration for a science class by pulling a crate across the floor and measuring the force with a spring scale. While she pulled, a student measured the acceleration of the crate with a handheld electronic device. The results of three trials are shown below. The teacher asked the class to calculate the acceleration of the crate based on the crate’s mass and the force she applied. What conclusion can be made about the difference between the CALCULATED acceleration and the ACTUAL acceleration that occurred in the trials?
Answer:
1. A 1,100 kg car comes uniformly to a stop. If the vehicle is accelerating at2 1.2 m/s, which force is closest to the net force acting on the vehicle?
-9,600 N
-1,300 N
-900 N
-94 N
Explanation: Awnser is 1,300
Which is the best unit of measurement to investigate the weight of rabbits?
a: inches b: tons c: ounces d: feet
HELP DUE TODAY!
Answer:
It is ounces because it is asking for weight and you would not measure a rabbit by tons
Answer:
C. Ounces
Explanation:
C. Ounces because inches and feet measure height or length not weight, and tons is wayyyy to much. Tbh I think pounds would be the best unit but since it's not an option then ounces is the best choice. (srry if I confused you)
Hope this helps :D

Which describes the ability to do work or to cause change?
physical change
matter
temperature
energy
Answer: Energy
Explanation: The ability to do work or cause change is called energy. Energy comes from many sources, and is found in two main forms. One form, potential energy, is energy that has the potential, in an object at rest, to do work later. An example of this would be a car parked at the top of a hill with its brakes on.

1. Identify at least two tools scientists use to study stars and galaxies, then explain how the tools you chose assist scientists in their work.
2. Name at least three properties of stars revealed by spectral characteristics
3. In 3-5 sentences, explain how a star is formed.
Answer: 1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.
2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then
2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.

A student jogs for a mile when their heartbeat starts racing and the student feels too fatigued to keep jogging. The student stopped to rest in response to the body's —
A. external stimulus of fatigue.
B. external stimulus of traveling a mile.
C. internal stimulus of sweating.
D. internal stimulus of a increased heart rate.
The student stopped to rest in response to the body's internal stimulus of a increased heart rate. That is option D.
What is heart rate?The heart rate is defined as the number of times the heart beats per minute. Depending on the state of the body it can increase or decrease per minute time
During exercise, the heart rate increases during exercise because the body need more oxygen which can be gotten by increased cardiac output.
Therefore, The student stopped to rest in response to the body's internal stimulus of a increased heart rate.
