Calculate the work done by a 2.4 N force pushing a 400 g sandwich across a table 0.75 m wide. Question 2 options: A. 3.2 J B. 1.8 J C. 960 J D. 533.33 J

What is the pressure from made from a book with the dimensions of 47 cm * 86 cm and a measured force of 900N?

You are the design engineer in charge of testing the crashworthiness of new automobile models. Cars are tested by smashing them into fixed, massive barriers at 50 km/h (30 mph). A new model of mass 1500 kg takes 0.

A current of I = 3.8 A is passing through a conductor with cross sectional area A = 2.5 x 10^-4 m^2. The charge carriers in the conductor, electrons, have a number density n = 1.3 x 10^27 m^-3. (a) Express the drift velocity of electrons through 1.

Before starting the simulation and having the waves encounter the barrier, the wavelength is manipulated. This is the (1. BLANK) variable. The pattern of diffraction will vary as a result of the change in wavelength.

A 400 kg object is sitting at rest at the top of a hill that is 30.0m high and 80.0m long measured along the hill. If there is no friction, how fast will the object be going at the bottom of the hill?

What does it mean when a plane is perpendicular to the x-axis?

If the weight of an object that is submerged in a fluid is 10 N and the buoyant force on it is 20 N, what will happen to the object?|

A switch in an electric circuit controls the flow of electrons in the circuit. True O False

What are three common forms of work in science

A boat travels north across a river at a velocity of 22 meters/second with respect to the water. The river's velocity is 2.2 meters/second to the east. What is the resultant velocity of the boat, as measured from the land?
