Well it determines on how much magnetism a material has.
Answer:
13.1 m/s
Explanation:
Given that a baseball is tossed up into the air at an initial velocity 18 m/s. The height of the baseball at time t in seconds is given by h(t) = 18t−4.9t 2 (in meters).
a) What is the average velocity for [1,1.5]?
To calculate the velocity travelled by the ball, differentiate the function.
dh/dt = 18 - 9.8t
Substitute t for 1 in the above Differential function
dh/dt = 18 - 9.8 (1)
But dh/dt = velocity
V = 18 - 9.8
V = 8.2 m/s
Average velocity = ( U + V ) / 2
Average velocity = (18 + 8.2)/2
Average velocity = 26.2/2
Average velocity = 13.1 m/s
Answer:
It is the way you see someone or something
Answer:
136000 J or 136 kJ
Explanation:
Formula
Heat = m * c * deltaH
Givens
m= 0.5 kg
c = 3400 J / (kg * oC)
Deltat = (100oC - 20oC)
deltat = 80oC
Solution
Heat = 0.5 kg * 3400 J/(kg* oC) * 80oC
Heat = 136000 Joules
Heat = 136 kg
Technically there is only 1 place of accuracy.
