a temperatura de um 100g de um líquido cujo calor específico é 0,5cal/g°C sobe de -10°C até 30°C. Em quantos minutos será realizado esse aquecimento com uma fonte que fornece 50 cal por minuto?

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.

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade
