I would say a because that is the only one that makes sense but I’m not 100% sure
The both contain a nucleus.
Answer:
2
Explanation:
There are 2 chlorine atoms in AgCl₂. So to balance the equation, there needs to be 2 atoms on the left side as well.
Answer:
1.024 × 10⁸ m
Explanation:
The velocity v₀ of the orbit 8RE is v₀ = 8REω where ω = angular speed.
So, ω = v₀/8RE
For the orbit with radius R for it to maintain a circular orbit and velocity 2v₀, we have
2v₀ = Rω
substituting ω = v₀/8RE into the equation, we have
2v₀ = v₀R/8RE
dividing both sides by v₀, we have
2v₀/v₀ = R/8RE
2 = R/8RE
So, R = 2 × 8RE
R = 16RE
substituting RE = 6.4 × 10⁶ m
R = 16RE
= 16 × 6.4 × 10⁶ m
= 102.4 × 10⁶ m
= 1.024 × 10⁸ m
Answer:
The time is
Explanation:
From the question we are told that
The diameter of the circular saw is
The peripheral speed is
The time taken for the blade to come to rest is t = 17 s
The total acceleration of the tooth considered is
Generally the radius of the blade is mathematically represented as
Generally the tangential acceleration of the blade is mathematically represented as
Here v is the final velocity of the tooth of the blade which is zero since the blade came to rest
so
=>
Generally the total acceleration of the tooth of the blade is mathematically represented as
Here is the radial acceleration , now making the subject of the formula we have that
=>
=>
Generally radial acceleration is mathematically represented as
Here is the velocity at which the total acceleration is 130 ft/s2.
=>
=>
=>
Generally the time at which the total acceleration is 130 ft/s2. is mathematically represented as
=>
=>
