Answer:
Explanation:
By analyzing the torque on the wheel we get:
Solving for T: 
On the object:
Replacing our previous value for T:
The relation between angular and linear acceleration is:
So,
Solving for α:
The linear acceleration will be:
And finally, the tension will be:
These are the values of all the variables: α, a, T
Answer:
for one its photo
Explanation: answers
this is easy 1. im not sure
2. erosion
3. is deposition
sorry i cant answer all of them but some simple ones deposition is when that stuff is getting moved, erosion is the breaking down of sokething and weathering is weather such as rain acid rain ice etc weather breeakin down rocks etc
Given:
f = 1160 kHz = 1160 x 10³ Hz
The velocity is c = 3 x 10⁸ m/s, the velocity of light (approximmately).
Calculate the wavelength, λ.
c = fλ
λ = c/f = (3 x 10⁸ m/s)/(1160 x 10³ 1/s) = 258.62 m
Answer: 258.6 m
Answer:
Explanation:
For this problem we must use Newton's second law where force is gravitational attraction
F = m a
Since movement is circular, acceleration is centripetal.
a = v2 / r
Let's replace
G m M / r² = m v² / r
G M r = v²
The distance r is from the center of the planet
r = R + h
v = √ GM / (R + h)
If the friction force is not negligible
F - fr = m a
Where the friction force must have some functional relationship, for example
Fr = b v + c v² +…
Suppose we are high enough for the linear term to derive the force of friction
G m M / r - (m b v + m c v2) = m v2
G M / r - b v = v²
We see that the solution of the problem gives lower speeds and that change over time.
To compensate for this friction force, the motors should be intermittently suspended to recover speed.
Answer:
The formula for density is d=M/V
Explanation:
where d is density, M id mass, V is volume.
