How much time (in seconds) is needed for a surgical cauterizer to raise the temperature of 3.00 g of tissue from 37.0 degrees C to 100 degrees C ad then boil away 0.200 g of water, if it puts out 3.50 mA at 20.0 kV? Ignore heat transfer to the surroundings. (Assume the specific heat of tissue is 3,500 J/(kg*degreeC) and the latnet heat of vaporization of water is 2,256 kJ/kg.)
How much time in seconds does it take to travel this straight line distance? Another similar elevator has been designed to travel a distance of 255 meters It has an acceleration of 0 879 meter per second squared It has a maximum speed of 360 meters per minute. This means that once reaches its maximum speed, i continues the rest of the journey at this maximum speed Hint - you have to do this in two separate parts as you...

QUESTION 3 How much time in seconds does it take to travel this from the ground floor to the top floor? Remember that the cab must start from rest when you get on and stop moving for you to get off. There will be three different types of motion. Another similar elevator has been designed to travel a distance of 363 meters from the bottom to the top floor It has an acceleration of 1.44 meter per second squared when...
How long? How much time in seconds does it take for the sled to go down part of a hill? A sled with a total mass of 602 kilograms is going down a straight part of a hill where the angle of incline is 10.8 degrees. The length of the straight part of the hill is 73.1 metres. The speed of the sled at the top of the hill is 4 meters per second. The combined forces of friction =...
4. How much time does it take for light from the sun to reach the earth? (The distance between the sun and the earth is, on average, 1.50 x 10 m. The speed of light in vacuum is 3.00 x 10° m/s.) 5. You drop a 1.00-kg lead ball from a height of 2.50 meters. How much times does it take for the ball to hit the ground?
A 5-horsepower, 75% efficient motor is used to raise a container 10 meters on the planet Mars, where gravitational acceleration is 3.711 meters per second squared. If the container is full of bromine (Br2), which has a specific gravity of 3.12 and has a total volume of 15 liters, how long does it take the motor to accomplish the task in units of seconds?
