Answer:
F = 1300 N
Explanation:
F = mv²/R = 0.4(100²)/3 = 1333.3333...
Answer:
705.6 N
Explanation:
The object is hanging on the rope, so there are two forces acting on the object:
- The force of gravity, downward, equal to
W = mg
where m is the mass of the object and g the acceleration of gravity
- The tension in the rope, T, upward
Since the object is hanging motionless, the object is in equilibrium, so we can write:
And therefore
For this problem,
m = 72 kg
Substituting,
Answer:
Heat is transferred directly from one particle of matter to another by the process of conduction.
A circular flow of warmer fluid and cooler fluid is called convection
Heat is always transferred from conduction to radiation
radiation is the transfer of energy by electromagnetic waves.
Heat that is transferred by the movement of currents within a fluid is called conduction
The only form of heat transfer that does not require matter is specific heat
Water bubbles up through a hot spring at Yellowstone National Park. What method of heat transfer is this?
convection
Explanation:
I hope that this helps, I kinda rushed on it
Answer:
wind speed i think where i live?
Answer:
Case I: 12.617 L/s
Case II: 161.406 cubic meters per hour
Case III: 1.062 Pound inches
Explanation:
<u>Given:</u>
- Speed of water flow = 200 gallons per minute
- Speed of air blow = 95 cubic feet per minute
- Measure of Torque = 12 Newton centimeter
<u>Assumptions:</u>
- 1 US gallon = 3.785 L
- 1 min = 60 s
- 1 ft = 0.3048 m
- 1 h = 60 min
- 1 inch = 2.54 cm
- 1 N = 0.2248 lb
Case I:
Case II:
Case III:
