His weight would be 154.32
Answer:speed of slower cyclist is 5 mph
Explanation:
Given
Distance between two cyclist is 50 miles
One cycle is 4 times fast as other
Speed of slower cyclist is r miles per hour
speed of faster cyclist is 4 r
they meet after t=2 hr
Distance traveled by fast cyclist is 
Distance traveled by slower cyclist is 






speed of slower cyclist is 5 miles per hour
No, because the word might offend that person.
Answer:
The average kinetic energy of the molecules increases
Explanation:
The temperature of a substance is proportional to the average kinetic energy of the particles in the substance.
In fact, for an ideal gas for instance, there is the following relationship:

where
KE is the average kinetic energy of the particles
k is the Boltzmann's constant
T is the absolute temperature of the gas
When we heat a substance (such as the flask of water in this problem), we are giving thermal energy to the particles of the substance; therefore, these particles will move faster on average, so their kinetic energy will increase (and the temperature of the substance will increase as well).
Answer:
Explanation:
From the given information:
The speed of a synchronous motor in relation to its frequency can be represented with the formula:

where,
the electrical frequency
is measured in Hz
the number of poles = P
For us to estimate the number of poles to have 50 Hz - 60 Hz Power, then we need to relate the frequencies of the above equation.
i.e

Thus, we can conclude that 10 poles synchronous motor is attached with 12 poles synchronous generator in order to convert 50 Hz to 60 Hz power.
