Answer: When you break on your bike and when you rub your hands together to get warm.
Explanation: Force and friction affect our daily lives in numerous amounts of ways. For instance, when a football is kicked, it moves faster later after some time its force decreases due to friction. A common example of friciton is when a bike stops. When the brakes are applied the friction on the pads cause the bike to stop. The rubbing hands is making friction. Which makes you get warm.
 
        
             
        
        
        
For this case, let's
assume that the pot spends exactly half of its time going up, and half going
down, i.e. it is visible upward for 0.245 s and downward for 0.245 s. Let us take
the bottom of the window to be zero on a vertical axis pointing upward. All calculations
will be made in reference to this coordinate system. <span>
An initial condition has been supplied by the problem: 
s=1.80m when t=0.245s 
<span>This means that it takes the pot 0.245 seconds to travel
upward 1.8m. Knowing that the gravitational acceleration acts downward
constantly at 9.81m/s^2, and based on this information we can use the formula:
s=(v)(t)+(1/2)(a)(t^2) 
to solve for v, the initial velocity of the pot as it enters
the cat's view through the window. Substituting and solving (note that
gravitational acceleration is negative since this is opposite our coordinate
orientation): 
(1.8m)=(v)(0.245s)+(1/2)(-9.81m/s^2)(0.245s)^2 
v=8.549m/s 
<span>Now we know the initial velocity of the pot right when it
enters the view of the window. We know that at the apex of its flight, the
pot's velocity will be v=0, and using this piece of information we can use the
kinematic equation:
(v final)=(v initial)+(a)(t) 
to solve for the time it will take for the pot to reach the
apex of its flight. Because (v final)=0, this equation will look like 
0=(v)+(a)(t) 
Substituting and solving for t: 
0=(8.549m/s)+(-9.81m/s^2)(t) 
t=0.8714s 
<span>Using this information and the kinematic equation we can find
the total height of the pot’s flight:
s=(v)(t)+(1/2)(a)(t^2) </span></span></span></span>
s=8.549m/s (0.8714s)-0.5(9.81m/s^2)(0.8714s)^2
s=3.725m<span>
This distance is measured from the bottom of the window, and
so we will need to subtract 1.80m from it to find the distance from the top of
the window: 
3.725m – 1.8m=1.925m</span>
 
Answer:
<span>1.925m</span>
 
        
             
        
        
        
The student’s suggestion who provides enough evidence to be able to determine the value of each resistor is student D.
<h3>What is current?</h3>
The current is the stream of charges which flow inside the conductors when connected across the end of voltage.
For the given set of parallel resistors, we need to find the resistance of each resistor.
From the Ohm's law, V =IR
R = V/I
Resistance value depends upon the voltage difference across the resistor  and the current flowing through that resistance.
Thus, the student D gives enough evidence to find resistance of the circuit is
