Answer:
3503.72 seconds
819.96 seconds
Explanation:
 =Velocity of river = 0.566 m/s
=Velocity of river = 0.566 m/s
 =Velocity of student = 1.17 m/s
=Velocity of student = 1.17 m/s
Distance to travel = 1.57 km = 1570 m
So,
Time = Distance / Speed

Time taken by the student to complete the trip is 3503.72 seconds
In still water

The difference in time between moving water and still water is 3503.72-2683.76 = 819.96 seconds
 
        
             
        
        
        
<span>Free electrons may be transferred between bodies by "Contact Action"
When positively charged body comes close to a negatively charged body, then electron flows from positively to negatively charged body

Answer:
The level of the root beer is dropping at a rate of 0.08603 cm/s.
Explanation:
The volume of the cone is :

Where, V is the volume of the cone
r is the radius of the cone
h is the height of the cone
The ratio of the radius and the height remains constant in overall the cone.
Thus, given that, r = d / 2 = 10 / 2 cm = 5 cm
h = 13 cm 
r / h = 5 / 13
r = {5 / 13} h


Also differentiating the expression of volume w.r.t. time as:

Given:  = -4 cm³/sec (negative sign to show leaving)
 = -4 cm³/sec (negative sign to show leaving)
h = 10 cm
So, 



<u>The level of the root beer is dropping at a rate of 0.08603 cm/s.</u>
 
        
             
        
        
        
The period of the oscillations.T = 1.2042s
Opposition is the process of any quantity or measure fluctuating repeatedly about its equilibrium value throughout time. This process is referred to as oscillation. Oscillation, a periodic fluctuation of a substance, can also be described as alternating between two values or rotating around a central value.
Typically, the mathematical formula for the moment of inertia is
T = 2 π √(I / mgd)
Therefore, a moment of inertia
I = 9.00×10-3 + md^2 ;
I=9.00*10^{-3}+ 0.5 * 0.3^2
I=0.054
T=2
T=1.2042s
The period of the oscillations.T = 1.2042s
