Every substance has a specific value of heat required in order to change the temperature of 1 gram of the substance by 1 degree celsius. specific heat is calculated by using the equation q=mcδt, where q represents heat in joules, m represents mass in grams, δt is the change in temperature in celsius, and c is the coefficient constant for a substance. what are the units for thecoefficient c.
a. c=j·g·°c
b. c=j·g/°c.
c. c=j/g·°c
d. c=g·°c/j

We know that Q is in joules, m is in grams, and Δt is in °C . Thus:
J = g * °C * c
c = J/(g * °C )
The answer is C

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
