A 5.7-kg block of aluminum is heated from 30°C to 70°C at atmospheric pressure. Find the amount of energy transferred to it by heat
In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin gold foil. He unexpectedly observed a few of the particles scattered almost directly backward.
An electron is initially at rest just outside a large copper surface that has a charge density of 1.04 10-6 C/m2. How far has the electron moved in 1.12 10-9 s if the field is uniform over this region
Because of intense competition, DLK struggled for the first few years of operation and the corporation sustained chronic losses. This year, Lacey, DLK's president, decided to seek additional funds to finance DLK's working capital.
A rectangular air mattress is 2.10m long, 0.48m wide and 0.09 m thick. If it has a mass of 2.30 kg, what additional mass can it support in water.
A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
