Answer:
a) 50 rad/s
b) 39.8 rev
Explanation:
Given:
r = 0.36 m
v₀ = 0 m/s
a = 1.8 m/s
t = 10 s
a) Find: ω
v = at + v₀
v = (1.8 m/s) (10 s) + (0 m/s)
v = 18 m/s
ω = (18 m/s) / (0.36 m)
ω = 50 rad/s
b) Find: Δθ
Δx = v₀ t + ½ at²
Δx = (0 m/s) (10 s) + ½ (1.8 m/s) (10 s)²
Δx = 90 m
Δθ = (90 m) / (2π × 0.36 m)
Δθ = 39.8 rev
PART A)
Here by force balance along Y direction
Force balance along X direction
now by torque balance
PART B)
now from above equations
now net reaction force of wall is given as
The ground exerts an equal force on the golf ball.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We calculate as follows:
</span>2.0x10^22 molecules H2O ( 1 mol / 6.022 x 10^23 molecules ) = 0.0332 moles H2O
Hope this answers the question. Have a nice day.
From the wording of the question, I'm suspecting that you have ...
... either a piece of equipment or else a computer program named "myDAQ",
... an inductor to play with and measure, either in your hand or on the screen.
I have none of these advantages.
In fact, nobody reading this on Brainly has.
It's like if I asked you to write an equation that can be solved to find the total amount of money in all five of my pockets right now.
