Physics 111 Final Exam Game

Front

What is the wavelength in a standing wave if 5 humps are seen in a 10 meter length?

Back

Wavelength = Length of wave / Number of humps = 10 m / 5 = 2 m.

Front

How do you calculate the speed of a block released from a height of 1 meter?

Back

Using the formula v = √(2gh), where g = 9.8 m/s², h = 1 m. Thus, v = √(2 * 9.8 * 1) = 4.4 m/s.

Front

What is the buoyant force on an object fully immersed in water with a volume of 0.00102 m³?

Back

Buoyant force = Volume * Density of fluid * g = 0.00102 m³ * 1000 kg/m³ * 9.8 m/s² = 10 N.

Front

What is the acceleration of a block sliding down a frictionless incline at 30 degrees?

Back

Acceleration = g * sin(θ) = 9.8 m/s² * sin(30°) = 4.9 m/s².

Front

What is the pressure difference between sea level and 0.001 meters below water?

Back

Pressure difference = Density * g * height = 1000 kg/m³ * 9.8 m/s² * 0.001 m = 0.098 kPa.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests or troughs in a wave.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

Explain buoyancy and its principle.

Back

Buoyancy is the upward force exerted by a fluid on an object immersed in it, explained by Archimedes' principle.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) = m * g * h, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the relationship between force, mass, and acceleration?

Back

Newton's second law states that Force (F) = mass (m) * acceleration (a).
