Imagine you pour some hot soup into a bowl. You place your hands on the outside of the bowl and feel that the bowl is very warm. How did the heat get from the soup through the bowl and into your hands?

In winter the air just above the top bunk bed is warmer than the air just above the bottom bunk bed, because warm air rises. Which of the following describes the method of heating that causes this difference in temperature

How to calculate aphelion

Steam (water vapor) at 100 degrees Celsius is added to a thermally insulated container with 200 kg of ice at zero degrees Celsius. The final mixture is water at 30 degrees Celsius. What was the initial mass of the steam?

3. A rectangular coil of wire (a = 21.0 cm, b = 45.0 cm) containing a single turn is placed in a uniform 7.80 T magnetic field, as the drawing shows. The current in the loop is 18.0 A.

before colliding, the momentum of block a is + 15.0 kg (m/s) and block b - 35.0kg (m/s). after block a has a momentum of - 12.0kg (m/s). what is the momentum of block b afterwards?

What would happen if everyone jumped at once?

An airplane cruises at 900 km/h relative to the air. It is flying from Denver, Colorado, due west to Reno, Nevada, a distance of 1200 km, and will then return. There is a steady 80 km/h wind blowing to the east.

On a bus traveling north at 20.0m/s, a child stands up and walks towards the back of the bus at 1.3m/s. What is the child's resultant velocity?

How do you think increasing the resistance in a circuit will affect the current in the wire

A ball is tossed into the air from height of 8 feet with an initial velocity of 8 feet per second. find the time r (in seconds) it takes for the object to reach the ground by solving the equation - 16t + 8t + 8 =
