Answer:
The terminal velocity is equal to C.
Explanation:
Making the assumption that k and t are positive, we then have that -kt is negative. The value of e^(-kt) will be equal to 1/(e^(kt))
If t increases, e^(kt) will increase exponentially and its reciprocal 1/(e^(kt)) will approach zero.
So, we have:
v(t) = C*(1-0)
v(t) = C*(1)
v(t) = C
Therefore, C is the terminal velocity.
Answer:
false
Explanation:
I am in need of points sorry
Answer:
well the the answer to the hypossis is that i think the pencil will leave a mark on my finger.
observation the indent will be there for a little if i do not press hard harder i press the longer the mark stay what made this diffrence is that my hypossis got somthing wrong. the thumb will not leave a mark that you can barly see and the index finger has visble mark because the end of the pincel shaper
and pionty and the eares side is flay so i barly leaves a mark
Explanation:
Answer:
There are 157 ft. above the bottom of the gorge
Explanation:
Cliff 1 (h) = 172ft.
Cliff 2(h) = 112 ft
Height difference between the cliffs: 172ft. -112 ft. = 60 ft
Width of the gorge = 80 ft
In this problem a right triangle is formed where the hypotenuse (T) is represented by the trestle's length, the width of the gorge is one of the legs and the leg opposite the angle (Ф) is represented by the difference in height between the cliffs.
T=
3/4 T = 3/4(100) = 75ft.
Calculating the height of the train from the lowest cliff, we will use the proportion of the sine of the angle that forms the trestle with the horizontal.
sin(Ф)=
x=
In order to know the height from the bottom of the cliff, we must add its height to this value.
h= 45ft. + 112ft. = 157 ft.
If Equal distance is traveled in equal interval of time then it is known as uniform motion in which velocity of object will remain same.
Then if distance covered will be same and the time taken to cover same distance is decreasing then it shows that speed is increasing with time due to which it took less time to cover same distance. This is also known as positive acceleration.
Now if the distance covered will be same and time taken to cover same distance is increasing then it shows that speed is decreasing with time due to which it took more time to cover the same distance. This is also known as negative acceleration.
Now in the above case it is given that the first mile takes you 10 minutes. The second mile takes you 20 minutes. So the time taken is increasing while we cover same distance so this is an example of <u>Negative Acceleration</u>
