<span>Internal energy changes that do not register on a thermometer are due to changes in the p</span>otential energy of the particles.
<span>Explanation: A thermometer measures the temperature, which is a measure of the average kinetic energy of the particles. </span>
I hope this helps! :)
Answer:
Explanation:
Conservation of momentum during the collision
0.023(230) + 2.0(0.0) = 0.023(170) + 2.0v
v = 0.69 m/s
The initial block kinetic energy will be converted to friction work
½mv² = Fd = μmgd
½(2.0)(0.69²) = 0.15(2.0)(9.8)d
d = 0.1619387... m
d = 16 cm
Answer: a) the radius is 17.846.
b) r = 17.846+-0.044cm
c) f(×) = πr^2, a=17.846cm, L=1000cm^2
Explanation: a) circle area = A = πr^2, then r = √(A/π) = √(1000/3.14) = 17.846
c) funtion is the area equation,
Answer:
G M m / R^2 = m v^2 / R centripetal force equals gravitational force
1/2 m v^2 = G M m / R = KE rearranging the above equation
T = 2 pi R / v time for one revolution (period)
T^2 = 4 pi^2 R^2 / v^2
From the very first equation v^2 = G M / R
so T^2 = 4 pi^2 R^3 / (G * M)
