How to calculate horizontal distance?A rock lies on the bottom of a 10m deep lake. You are in a boat directly above the rock, and you can see it well. As the boat moves away from the rock, after a certain horizontal distance x. you cannot see the rock anymore. What is the ...
The distance s that an object falls is directly proportional to the square of the time t of the fall. If an object falls 16 feet in 1 second, how far will it fall in 3 seconds? Calculate the height (in m) of a cliff if it takes 2.33s f...
Step 2:Calculate the wavelengthλusing the equation:λ=vf. Step 3:The minimum path difference required for destructive interference is equal to half of the wavelength:λ2. What is Destructive Interference? Destructive interference:When multiple waves overlap their amplitudes are combined resulting in ...
Learn how to calculate the number of electrons passing through a point in a wire, and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills.
Convert the volume to m3. Divide the mass by the volume. You will then have the density of the object in units of kg/m3. How do I calculate the density of the Earth? Note the mass of Earth in kilograms, which is 6×1024 kg. Look up the volume of the Earth in m3, which is ...
The first step to understanding what it means to calculate the magnitude of a force in physics is to learn what a vector is. A "scalar" is a simple quantity that just has a value, such as temperature or speed. When you read a temperature of 50 degrees F, it tells you everything you...
Ignore wind resistance to calculate the distance traveled by a bullet using the simple formula: \(x=v_{0x}\sqrt{\frac{2h}{g}}\) Where (v0x) is its starting speed, (h) is the height it's fired from and (g) is the acceleration due to gravity. ...
i used physics to calculate how much yoda weighs in the empire strikes back, luke does a one-armed handstand with yoda balanced on his foot. using this, i can estimate the mass of yoda. lucasfilm save save everyone knows luke skywalker travels to dagobah to learn the ways of the force...
We are trying to control a container with water inside. The container has two phases of operation. In one phase, the container is tilted. In this tilted state, the distance from the observation point (red dot) to the surface of the water (distance B) is known from a measu...
Step 3: Use the equation of continuity to calculate the area of the unknown cross-section. We will start with the equation of continuity: A1v1=A2v2 v2 A2=A1v1v2=(9.5cm2)(0.42m/s)2.5m/s≈1.6cm2 Notice that the units do not have to agree since this is essentially a ratio of...
