Explanation:
Given that,
Mass of disk = 1.2 kg
Radius = 0.07 m
Radius of rod = 0.11 m
Mass of small disk = 0.5 kg
Force = 29 N
Time t = 0.022 s
Distance d= 0.039 m
(I). We need to calculate the speed of the apparatus
Using work energy theorem
Where, m = total mass
v = velocity
F = force
d = distance
Put the value into the formula
(b). We need to calculate the angular speed of the apparatus
Using formula of torque
We need to calculate the angular speed of the apparatus
Using equation of angular motion
Put the value into the formula
(c). We need to calculate the angular speed of the apparatus
Using equation of angular motion
Put the value into the formula
Hence, This is required equation.
Answer:
The right answer is option C
Answer:
0.98 g/m
Explanation:
Note: Since Tension and frequency are constant,
Applying,
F₁²M₁ = F₂²M₂............... Equation 1
Where F₁ = Frequency of the G string, F₂ = Frequency of the A string, M₁ = mass density of the G string, M₂ = mass density of the A string.
make M₂ the subject of the equation
M₂ = F₁²M₁/F₂²............... Equation 2
From the question,
Given: F₁ = 196 Hz, M₁ = 0.31 g/m, F₂ = 110 Hz
Substitute these values into equation 2
M₂ = 196²(0.31)/110²
M₂ = 0.98 g/m
Answer:
magma forming above a subducting plate slowly rise into the overriding crust causing the formation of a volcano
Explanation:
Answer:
Momentum,
Explanation:
Given that,
Mass of a mosquito, m = 0.000015 kg
Velocity of the mosquito, v = 5.2 m/s
We need to find the momentum of the mosquito. The momentum of an object is given by :
p = mv
Put all the values in the above formula.
So, the momentum of the mosquito is .
