Often we think that heat and temperature are the same thing. ... Heat and temperature are related to each other, but are different concepts. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.
light can travel 5,874,601,670,040 in a year around the earth
speed = 86km/hr
= 86000/3600
= 23.889m/s
time = 4.6s
acceleration = 23.889/4.6
a = 5.19m/s^2
They are called mechanical waves
Answer:
Explanation:
We use the harmonic motion position equation:
where A = 0.350 and for t = 0
so:
and also:
so we have:
x(t)=0.350cos(1.532 t)
For t = 3.403 s
x(3.403)=0.350cos(1.532 (3.403)) = 0.348 m
