Final Exam Review: PS

Front

Convert 56°C to K.

Back

To convert Celsius to Kelvin, use the formula: K = °C + 273.15. Therefore, 56°C = 56 + 273.15 = 329.15K, rounded to 329K.

Front

Express the number 0.005802 in scientific notation.

Back

0.005802 in scientific notation is 5.802 x 10^-3.

Front

A 100N force causes an object to accelerate at 2m/s². What is the mass of the object?

Back

Using Newton's second law, F = ma, we can find mass (m) as m = F/a. Thus, m = 100N / 2m/s² = 50kg.

Front

A student walks 3 blocks South, 4 blocks West, and 3 blocks North. What is the distance the student walked?

Back

The total distance walked is 3 + 4 + 3 = 10 blocks.

Front

Which 2 particles are located in the nucleus of the atom?

Back

The two particles located in the nucleus of the atom are protons and neutrons.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

Define scientific notation.

Back

Scientific notation is a way of expressing numbers as a product of a coefficient and a power of 10, making it easier to work with very large or very small numbers.

Front

What is the SI unit of mass?

Back

The SI unit of mass is the kilogram (kg).

Front

How do you calculate the total distance traveled in a multi-directional walk?

Back

To calculate total distance, sum all individual distances walked, regardless of direction.

Front

What is the relationship between temperature in Celsius and Kelvin?

Back

The relationship is K = °C + 273.15, meaning Kelvin is always 273.15 units higher than Celsius.
