What is the speed in m/s of a wave with a wavelength of 0.75m and a frequency of 2.4 Hz?

speed = wavelength x frequency

0.75 x 2.4 = 1.8m/s

What is the relationship between the period (T) of a pendulum and its length (L)?

T = 2ㅠ√(L/g)  – The period (T) is proportional to the square root of the length (L)

You and three friends are stuck on a planet far away. A tsunami will arrive to your location in 17 minutes, and you need to cross a bridge to reach your ship and escape. The bridge can only support two people at a time, and each friend takes a different amount of time. You take 1 minute, Friend B takes 2, Friend C 5, and Friend D 10. Additionally, it is nighttime, so one person must bring a flashlight back across the bridge to the starting side before anyone else can cross. How will you get everyone across in time?

First, Friend B and I will cross, taking 2 minutes, and I will return, taking 1 minute. (3 minutes have passed).

Then Friend C and Friend D will cross, taking 10 minutes, and Friend B will take it back, (12 minutes for this step, 15 minutes have passed).

Then Friend B and I will cross, taking 2 minutes (2 minutes for this step, 17 minutes have passed).

Assuming there is no air resistance, how long will it take for a ball that is thrown straight up with an initial velocity of 20m/s to return to the thrower’s hand? 

t = [ v(f) - v(i) ] / a   →   t = (0 - 20) / -9.8  →  t = 2.04s x 2 = 4.08s

When 6.00 grams of hydrogen gas react with excess oxygen, this is the maximum mass of water that can be produced.

What is 54.0 grams of water? 2H2 + O2 -> 2H2O. Explanation: Step 1. Use the molar mass of H2 to find how many moles 6 grams is (6 g/2.02 g/mol = 2.97). Step 2. Since H2 and H2O have a 1:1 ratio, they have an equivalent number of moles. Step 3. Use the molar mass of H2O and multiply it by the moles of H2O (2.97 mol x 18.02 g/mol = 53.5 g -> 54 g)

A 24V battery is connected to three resistors in series: R(1) = 5 ohms ; R(2) = 10 ohms ; R(3) = 15 ohms. What is the total current? What is the voltage drop across R(2)?

a) R(total) = 5 + 10 + 15 = 30 ohms → I = V/R(total) → I = 24V/30 ohms = 0.8 amp     b) Voltage drop across R(2) = I x R(2) → V(R2) = 0.8 amp x 10 ohms = 8V
