Answer:
C) 5ML^2
Explanation:
2 Spheres of mass M
Bug's mass 3M
Rod length 2L, radius L
Find Rotational Inertia I
I=Σmr^2
I=(3M+M+M)L^2
I=5ML^2
Answer:
Q = 2687130 J
Explanation:
m = mass of block of ice = 5 kg
= Initial temperature of ice block = - 27 °C
= final temperature of water = 35 °C
= specific heat of ice = 2108 J/(Kg °C)
= Latent heat of fusion of ice = 334000 J/kg
= specific heat of water = 4186 J/(Kg °C)
Heat added is given as
<span>The wavelength of a wave is
A) how strong the wave is.
B) the distance between a peak of the wave and the next trough.
C) the distance between two adjacent peaks of the wave.
D) the distance between where the wave is emitted and where it is absorbed.
E) equal to the speed of the wave times the wave's frequency.</span><span>
the right answer is C
C) the distance between two adjacent peaks of the wave.</span>
Answer:
P = 9800 [Pa]
Explanation:
In order to calculate the pressure at the bottom, we must use the following formula.
P = Ro*g*h
where:
P = pressure [Pa] (units of pascals)
Ro = density of the water = 1000 [kg/m³]
g = gravity acceleration = 9.8 [m/s²]
h = height = 1 [m] (because its half of the portion, the full height is 2 m)
P = 1000*9.8*1
P = 9800 [Pa]
