Answer:
A
Explanation:
absolute magnitude and luminosity vs the spectral position/ temperature
 
        
             
        
        
        
The right answer for the question that is being asked and shown above is that: "1-4-3-2." (main sequence-->red giant-->supergiant-->white dwarf). Assume that all four H-R diagrams below represent a star in different stages of its life, after it starts to fuse hydrogen in its core.
        
                    
             
        
        
        
1 farad = 1 coulomb/volt
5 μF = 5 x 10⁻⁶ coulomb/volt
        = 60 x 10⁻⁶ coulomb / 12 volts
The charge is 60 x 10⁻⁶ coulombs = 6 x 10⁻⁵  (choice-A) 
        
             
        
        
        
Answer:
Explanation:
The impulse equation is 
Δp = FΔt, where Δp = final momentum - initial momentum, F is the Force exerted on an object, and Δt is the change in time. In this equation,the entire right side defines the impulse. In other words, FΔt is the impulse; thus the change in momentum an object experiences is due to its change in impulse and is directly proportional to it. 
Therefore, once we find the change in momentum, that is the impulse the object experiences. Δp = final momentum - initial momentum, where 
p = mv and p is momentum.

 ; therefore,
; therefore,
Δp = 25.0 - 17.5 = 7.5 which is the unit for momentum
 which is the unit for momentum
