Answer:
it can melt orcan put them past their boiling point
Explanation:
Answer:
B) R1 = 6 V and R2 = 6V
Explanation:
In series, both resistors will carry the same current.
that current will be I = V/R = 12 / (10 + 10) = 0.6 A
The voltage drop across each resistor is V = IR = 0.6(10) = 6 V
Hello!!
For this, we only need frequency and speed, so for calculate we applicate formula:
Answer:
No fallacy
Explanation:
The statement that at least 50% of the students at Northern State own an iPod is best categorized as no fallacy.
This statement is very true and consistent with the facts presented in the passage.
A fallacy is a mistaken belief usually based on biased arguments.
Total number of students sampled = 200
Number of iPod owners = 150
Percentage of iPod owners = 
x 100
Percentage of iPod owners = 
x 100 = 75%
We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.
Answer:
e. 2ωs / √5
Explanation:
The rotational kinetic energy of any rigid body, like an extension of the translational kinetic energy, is defined as follows:
Krot = 1/2 *I * ω²
For a solid sphere of mass M and radius R, the moment of inertia regarding any axis through its center, is as follows:
I =2/5 M*R²⇒ Krot(sp) = 1/2 (2/5 M*R²)*ωs² (1)
For a solid cylinder, rotating through an axis running through the central axis of the cylinder, the moment of inertia can be calculated as follows:
I = 1/2 M*R² ⇒ Krot(c) = 1/2 (1/2*M*R²)*ωc² (2)
As both rotational kinetic energies must be equal each other, we can equate (1) and (2), as follows:
1/2 (2/5 M*R²)*ωs² = 1/2 (1/2*M*R²)*ωc²
Simplifying common terms, and solving for ωc, we have:
ωc = 2*ωs /√5
