A projectile is launched at 20m/s at 60 degree angle from the horizontal. How much time does it take for the projectile to land, assuming it lands on ground that is level with the launch site? - 3.6s Which of the following is not a unit of the metric system or Systeme International? - Yard A snow skier is at the top of a mountain trying to decide which ski run to take since they all have different slopes. He wants to slide down with a constant speed. If the coefficient of kinetic friction b...

AC HPAT Physics Exam Solved 100% Correct!! DIstance · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direction ...

What does a vector measure? Correct Answer-magnitude/size and direction What do scalars measure? Correct Answer-Magnitude/size What is distance? Correct Answer-how far something has traveled What is speed? Correct Answer-how fast something is going What is velocity? Correct Answer-how fast something is going in a certain direction (Displacement/time) What is a vector sum? Correct Answer-addition if vectors together What is the rate of speed? Correct Answer-distance over time ...

What is: Design wind pressure? Correct Answer-Design wind pressure: Minimum design value for the equivalent static pressure on the exterior surfaces resulting from critical wind velocity (equal to a reference wind wind pressure measured at 33', 10m). The # is modified by a bunch of coefficients to account for: exposure conditions, building height, wind gusts, geometry/orientation. Why are horizontal forces more critical than vertical ones in seismic design? Correct Answer-Because structure...

Orthotic Certification Test (Latest 2024/ 2025 Update) Questions and Verified Answers| 100% Correct| Grade A+ What is the force that is equal in magnitude of the foot striking the ground? ground reactive force IF GRFV is anterior to the axis, there is ____________ rotation of the proximal segment anterior IF GRFV is posterior to the axis, there is ____________ rotation of the proximal segment posterior IF GRFV is medial to the axis, there is ____________ rotation of the proximal se...

scalar - correct answer quantity that represents only magnitude, e.g., time, temperature, or volume. It is expressed using a single number, including any units. vector - correct answer quantity that represents magnitude and direction. It is commonly used to represent displacement, velocity, acceleration, or force. Displacement (s) - correct answer the distance and direction of a body's movement (an airplane flies east 100 nm). Velocity (V) - correct answer the speed and directi...

Honors Physics Final Exam Questions and Answers Graded A+ What is the principle of inertia? The principle of inertia states that an object will not change its state of motion unless acted upon by an external force. How does friction affect the motion of an object? Friction opposes the motion of an object, causing it to slow down or stop. What is the concept of momentum? Momentum is the quantity of motion an object has, which depends on its mass and velocity. What is the dif...

GCSE AQA [TRIPLE] Physics AQA PSYCHOLOGY PAPER 2 LATEST EXAM 2024 EXPERT CERTIFIED QUESTIONS AND ANSWERS Difference between scalar and vector: - CORRECT ANSWER--scalar = magnitude only -vector = direction and magnitude The only vector quantities are: - CORRECT ANSWER-- acceleration -velocity -force -displacement -momentum -weight Force - CORRECT ANSWER--a push or a pull Balanced forces - CORRECT ANSWER--when 2 forces acting on an object are equal in size but act in opposite dire...

Torque is given by the formula, , where is a force and is a displacement. Which of the following is the magnitude of torque resulting from a 2.4 N force applied 17 cm from the point of rotation, if the force is applied perpendicular to the displacement vector? Select one: a. 0 N⋅m b. 40.8 N⋅m c. 0.41 N⋅m d. 4.1 N⋅m A toy robot is programmed to move in a straight line across a desktop according to the equation , where x is in inches and t is in seconds. At some point during the m...
