Answer:
θ =607.33°
Explanation:
Given that
Angular acceleration α = 3.45 rad/s²
Initial angular speed ,ω = 1.85 rad/s
The angle rotates by wheel in time t
Now by putting the values
θ = 10.6 rad
θ =607.33°
Therefore angle turn by wheel in 2 s is θ =607.33°
The correct answer for this question would be an EARTHQUAKE. What happens when two plates bordering each other suddenly move and release energy is an earthquake. When these plates slip one another and energy is released, this results in an earthquake. Hope this answer helps.
Answer:
28 grams
Explanation:
The equation for the reaction is
3H(2) + N(2) -> 2NH(3)
Then we have.
The molar mass, M of ammonia is 17 g/mol.
34 grams of ammonia, NH3 then would be
34 g / 17 g/mol
= 2 moles
2 moles of ammonia will be obtained from
(2 * 1) / 2
= 1 mole of nitrogen
The molar masses of nitrogen is 28 g/mol
2 moles of nitrogen corresponds to 1 * 28 = 28 grams.
Answer:
I'm no expert, but multitasking is a no bueno. Because multitasking reduces your efficiency and performance because your brain can only focus on one thing at a time. When you try to do two things at once, your brain lacks the capacity to perform both tasks successfully.
Therefore I would choose A, considering he could easily workout another time, whilst the test is a one time thing. He can't redo the test, but he can workout again. So my answer is A.
If he HAS to workout and study at the same time, then C would be appropriate.
I hope this helps!
Answer:
The speed of disk is 1.98 
Explanation:
Given:
Mass of 
kg
Spring constant 
Compression of spring 
m
From energy conservation theorem,
Spring potential energy converted into kinetic energy,
Therefore, the speed of disk is 1.98
