t = total time taken by sound to go down the well and then come back = 2 sec

d = depth of the well

D = total distance traveled by the sound

total distance traveled by sound is given as

total distance traveled = distance traveled going down + distance traveled going up

D = d + d

D = 2 d                                                               eq-1

v = speed of sound = 343 m/s

we know that distance traveled is given as

total distance traveled = speed of sound x total time

D = v t

using eq-1

2 d = v t

2 d = (343) (2)

dividing both side by 2

d = 343 x 2/2

d = 343 m

hence surface of water is 343 m deep

Bacteria move back and forth by using their flagella (structures that look like little tails). Speeds of up to 50 μm/s ⎛ ⎝50×10−
Rzqust [24]

Answer:

Explained

Explanation:

Displacement is the change in the position of an object with reference to a starting point. for displacement to occur the position of the object must change.

Here the bacteria although moving but it is moving back and forth, meaning its initial and final positions are the same and hence no displacement. Whereas distance is the total distance traveled no matter in what direction. Hence, The total distance traveled by a bacterium is large for its size, while its displacement is small.

The ability to distinguish between acceleration and velocity will be critical to your understanding of many other concepts in th
Sauron [17]

Answer:

Object could only be moving with increasing speed.

Explanation:

Let us consider the general formula of acceleration:

a = (Vf - Vi)/t

Vf = Vi + at   -------- equation 1

where,

Vf = Final Velocity

Vi = Initial Velocity

a = acceleration

t = time

<u>FOR POSITIVE ACCELERATION:</u>

Vf = Vi + at

since, both acceleration and time are positive quantities. Hence, it means that the final velocity of the object shall be greater than the initial velocity of the object.

Vf > Vi

It clearly shows that if an object moves with positive acceleration. <u>It could only be moving with increasing speed.</u>

Solving the same equation for negative acceleration shows that the final velocity will be less than initial velocity and object will be moving with decreasing speed.

And for the constant velocity final and initial velocities are equal and thus, acceleration will be zero.
