80 PERCENT FOR THE TEST YAY THANK YOU

just to tell u guys I was TeenIdleMarinaAndTheDiamonds and SEASONOFTHEWITCH if you were at the last two assignments.

UNIT TEST. Xander reached a final velocity of 4.5 m/s for 3.5 seconds. Finley reached a final velocity of 3.6 m/s for 4.2 seconds. Max reached a final velocity of 7.3 m/s for 1.2 seconds. They all started at the same location from rest. Which lists them f...

Two objects collide and bounce apart. Assuming no outside forces act on the system, which best describes the total momentum after the collision? It is always greater than it was before the collision. It is often greater than it was before the collision. I...

The table represents the speed of a car in a northern direction over several seconds. A 2-column table with 5 rows. The first column labeled Column 1 has entries 0, 2, 4, 6, 8, 10. The second column labeled Column 2 has entries 5, 10, 15, 20, 25, 30. Colu...

Engineers are trying to improve a race car. Their goal is to increase the acceleration of the car using the same engine. Which change shows the best application of Newton’s laws of motion to achieve this goal? increasing the inertia of the car decreasing...

Which describes an object’s speed when free falling in a vacuum? The object accelerates until it reaches its terminal velocity. The object falls at a constant speed because only one force acts on it. The object falls faster and faster until it strikes the...

Scientists launch a rocket, and they monitor its acceleration and the force exerted by its engines. As the rocket gets higher, the monitors show that the acceleration of the rocket is increasing but the force exerted stays the same. How do Newton’s laws e...

What is determined by calculating the slope of the position vs time graph? position velocity distance displacement

A factory employee spends two hours putting together a car part. A machine can do the same job in thirty minutes. Which statement best describes the time-effectiveness of this scenario? The employee is four times as time-effective as the machine. The mach...

Rachel wants to develop a lamp that will work using a remote control. Which statement best describes the process she should use? She should use scientific investigation because she will need to analyze the results. She should use technological design beca...

What must be included when describing the displacement of an object? measurement and direction direction and speed total distance and position speed and total distance

Kai was 200 meters north of the library when he remembered he had to return some books to the library. It took him 200 seconds to do the round trip. Which best describes Kai’s roundtrip? His speed was 1 m/s, and his velocity was 0. His speed was 2 m/s, an...

What kind of acceleration occurs when an object speeds up? positive negative neutral zero

Sayid made a chart listing data of two colliding objects. A 5-column table titled Collision: Two Objects Stick Together with 2 rows in the first 3 columns and 1 row in the last 2 columns. The first column labeled Object has entries X, Y. The second column...

What is the first stage of both technological design and scientific investigation? communicate the findings evaluate the product identify a problem conduct background research

Levi and Clara are trying to move a very heavy box. Levi is pushing the box with a force of 30 N, and Clara is pulling the box with a force of 50 N. The box exerts a frictional force of 65 N. Which best explains the forces? There is a net force of 15 N ag...

I DONT LIKE IT WHEN U DONT ANSWER ANYMORE copy n paste this: Levi and Clara are trying to move a very heavy box. Levi is pushing the box with a force of 30 N, and Clara is pulling the box with a force of 50 N. The box exerts a frictional force of 65 N. Wh...
