Why does a rocket keep accelerating?

Why does a rocket keep accelerating? As the rocket velocity increases, it encounters air resistance, or aerodynamic drag, which opposes the motion. Drag increases as the square of the velocity. The thrust of the rocket must be greater than the weight plus the drag for the rocket to continue accelerating. Do Newton’s laws apply in […]

What makes up 80% of air?

What makes up 80% of air? Air is composed of a mixture of gases and is not a gas in itself. However, air is mostly nitrogen — almost 80 percent of it. Nearly all the rest of it is oxygen, with about 1 percent being argon. All of the rest of the gases make up […]

Which gun has the most recoil?

Which gun has the most recoil? 950 JDJ. This gun is no joke. It uses 240 grains of powder to push a 2,400-grain bullet 2,100 fps. It bites on both ends though, generating 277 foot-pounds of recoil, or approximately 10 times as much as a 30-06. What rifle kicks the hardest? Petzal: The Hardest Kicking […]

Is buoyant force constant?

Is buoyant force constant? Because the volume is the same at any depth, and the density of water is the same at any depth, the total mass of displaced water (mass = volume x density) is the same at any depth—making the buoyant force constant. Why is a heavier object more likely than a lighter […]

Which graph shows the motion of the car?

Which graph shows the motion of the car? The speed-time graph represents the motion of a car travelling along a straight level road. What is secondary motion SSM? Secondary motion is totally event-dependent. Tertiary motion is especially fast object motion. Who decides the agenda for a meeting? Who Should Create the Meeting Agenda? Board meeting […]

What is the study of matter and energy called?

What is the study of matter and energy called? Chemistry and Physics Chemistry is the study of matter and energy at the scale of atoms and molecules. For example, the synthetic fibers in the swimmer’s suit were created in labs by chemists. Physics is the study of matter and energy at all scales—from the tiniest […]

Is Probeware an electronic tool?

Is Probeware an electronic tool? Probeware is a learning tool that connects probes and sensors to a computer running suitable software and allows students to view real-time data in a variety of formats. When placed in an inquiry-based learning context, this capacity can significantly increase speed learning. Which best describes technology’s use in science? The […]
