how the energy is produced in a nuclear reactors?

A hiker sets out on a trek heading [N35degreesE] at a pace of 5.0km/h for 48.0 min. He then heads west at 4.5km/h for 40.0 min. Finally, he heads [N30degreesW] for 6.0km/h, until he reaches the camground 1.5 hours later. What is his total displacement?

why is the curve radius minimum when a projected ballistic ball reaches the maximum height?

A 25g rifle bullet traveling 220m/s buries itself in a 3.9kg pendulum hanging on a 2.6m long string, which makes the pendulum swing upward in an arc. Determine the vertical and horizontal components of the pendulum's displacement.

Farmer Crockett is preparing tomato seedlings for his spring planting by growing the small plants over five 46-ohms strip heaters wired in parallel. a) How much current does each heater draw from a 120-V line? b) How much current do they all have together?

Timmy is playing with a new electonics kit he has recieved for his birthday. He takes out four resistors with resistances of 15ohms, 20ohms, 20ohms, and 30ohms. a) How would Timmy have to wire the risistors so that they would allow the maximum amount of current to be drawn? Calculate the total resistance in this circuit. b) How must he wire the resistors so that they draw a minimum amount of current? Calculate the total resisance in this circuit.

Titan’s size (R = 2575 km) and density (ρ = 1.9 g cm -3) are much smaller than Earth’s (R = 6378 km and ρ = 5.5 g cm -3). Therefore, we would expect that its surface gravity gT is weaker than Earth’s g, so any material on Titan would weigh much less than it does on Earth (the weight of any mass m on any planet (or moon) is given by the product of its mass m and surface gravity g, i.e., W = mg). However, atmospheric pressure on Titan’s surface is greater than Earth’s, about 1.6 Earth atmospheres (pressure is the weight per square meter on the surface of the planet (or moon), i.e., P = W / A where A is the area)! This means that the amount of mass in Titan’s atmosphere above any square meter of Titan’s surface must be much greater than the amount of mass in the atmosphere of Earth above any square meter on Earth’s surface. Calculate the amount mass of atmosphere per square meter (we’ll call this σ = m/A) on Titan’s surface compared to that on Earth. (Hint: You’ll need to calculate Titan’s surface gravity relati
