Answer:
a) True. There is dependence on the radius and moment of inertia, no data is given to calculate the moment of inertia
c) True. Information is missing to perform the calculation
Explanation:
Let's consider solving this exercise before seeing the final statements.
We use Newton's second law Rotational
τ = I α
T r = I α
T gR = I α
Alf = T R / I (1)
T = α I / R
Now let's use Newton's second law in the mass that descends
W- T = m a
a = (m g -T) / m
The two accelerations need related
a = R α
α = a / R
a = (m g - α I / R) / m
R α = g - α I /m R
α (R + I / mR) = g
α = g / R (1 + I / mR²)
We can see that the angular acceleration depends on the radius and the moments of inertia of the steering wheels, the mass is constant
Let's review the claims
a) True. There is dependence on the radius and moment of inertia, no data is given to calculate the moment of inertia
b) False. Missing data for calculation
c) True. Information is missing to perform the calculation
d) False. There is a dependency if the radius and moment of inertia increases angular acceleration decreases
Answer:
T = 144°C
Explanation:
From the law conservation of energy,
Heat loss = Heat gain
mc(T-50) = 2mc(50-3)
T-50 = 2(47)
T-50 = 94
T = 94+50
T = 144°C
Plz check it out
Well idk if this helps but the formula to solve acceleration is
a=F/m=(100kg)=1.0m/s 2
The irradiance of the sun dependent on the wavelength of the radiant energy it emits.
<h3>
What is irradiance of the sun?</h3>
The solar irradiance is the output of light energy from the entire disk of the Sun, measured at the Earth.
The energy output is given as;
E = hf
E = hc/λ
where;
- c is speed of light
- f is frequency of the light
- λ is wavelength of the light
Thus, we can conclude that the irradiance of the sun dependent on the wavelength of the radiant energy it emits.
