Think about your displacement at three different times throughout your day and compare it with e distance you traveled. (6 point

photoshop1234 [79]

Here, we are asked to calculate the total distance and displacement for three different times.

Before solving the question, first we have to understand the distance and displacement.

Displacement is the minimum distance travelled between two points. Hence, it is a vector quantity. On the other hand, the distance travelled is a scalar quantity.

The total displacement will be calculated by vector addition while total distance will follow algebraic addition.

Let us consider Ram travelled 3 km towards north from his home to office in 1 hour. The highway is straight. He reached at his office and saw that his office was closed. So, he came back. He stopped at shop for 2 minutes which was 2 km away from his office. Then he started his journey and reached him home.

Let his first distance travelled from home to office is $s_{1} =\ 3\ km$

Here, the displacement is also the same in magnitude with distance travelled and it is directed towards north.

The distance travelled by Ram from office to the shop $s_{2} =2\ km$

Here, the displacement is 2 km towards south.

The distance travelled by Ram from the shop to the office $s_{3} =\ 1 \ k m$

Here, the displacement is 1 km towards south.

Here, the total distance travelled $[s]\ =\ s_{1} +s_{2} +s_{3}$

$=3\ km+2\ km+1\ km$

$=6\ km$

Now we have to calculate the total displacement. Here, the total displacement is zero.

It is because the initial and final points of his journey is same.

What is pulling force expansion

Aloiza [94]

Answer:

physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time

An object is moving east with a constant speed of 30 m/s for 5 seconds. What is the object's acceleration

pentagon [3]

Answer:

<h3>The answer is 6 m/s²</h3>

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

$a = \frac{v}{t} \\$

where

v is the velocity

t is the time

We have

$a = \frac{30}{5} \\$

We have the final answer as

Hope this helps you

You are caulking a window. The caulk is rather thick and, to lay the bead correctly, the exit nozzle is small. A caulking gun us

ZanzabumX [31]

Answer:

The answer is

A. Pressure is distributed uniformly throughout the fluid and the area of the plunger is much larger than the area of the opening.

Explanation:

The question is incomplete, here is a complete question with full options

You are caulking a window. The caulk is rather thick and, to lay the bead correctly, the exit nozzle is small. A caulking gun uses a plunger which is operated by pulling back on a handle. You must squeeze the handle very hard to get the caulk to come out of the narrow opening because:_________.

A. pressure is distributed uniformly throughout the fluid and the area of the plunger is much larger than the area of the opening.

B. viscous drag between the walls of the tip and the caulk causes the caulk to swirl around chaotically.

C. Newton’s third law requires most of the energy in the caulk to be used to push back on the plunger rather than moving it through the tip.

D. the high density of the caulk impedes its flow through the small opening.

Since the caulk is thick and the exit nozzle is small, the pressure needed to deliver the caulk will be very high as pressure is uniformly distributed at the plunger side at every part of the caulk, hence very high pressure is needed to deliver the caulk which is why the handle needed the very hard squeeze
