Speed = (distance covered) / (time to cover the distance)
Speed = (1,000 meters / 8.6 minutes) x (1 minute / 60 seconds) = 1.94 m/s

Answer:
Option C. Rate of change of velocity
Explanation:
To know the correct answer to the question, it is important we know the definition of power.
Power can be defined as the rate at which work is done. Mathematically, it is expressed as:
Power = work / time
Work and energy has the same unit of measurement i.e joule. Thus, power can also be defined as the rate at which energy is transferred i.e
Power = enery / time
Energy is measured in Joules and time in second. Thus, power can also be defined as amount of joules transfered per second.
Power = Joule / sec
The rate of change of velocity on the other hand is termed acceleration.
Thus, the answer to the question is option C.
There are two possible answers that I can see, C or D
Answer:
Explanation:
heat lost by block of copper
= mass x specific heat x fall in temperature
= .04 x 385 x ( 95 - 24 )
= 1093.4 J
Heat gained by water
= .105 x 4200 x ( 24 - T ) ; Here T is initial temperature of water .
= 441 ( 24 - T )
heat lost = heat gained
1093.4 = 441 ( 24 - T )
24 - T = 2.48
T = 21.52 ℃
Measured on the richter scale, majority of earthquakes are near the pacific. Sorry thats all i know
