Answer:

0.641 seconds

Explanation:

Distance (d) = 1.0 km

Using the relation :

Speed = distance / time

Time = distance / speed

Speed of sound in seawater is about 1560 m/s

Distance = 1.0km =

1km = 1000m

Time = 1000 / 1560

Time = 0.6410256

Time = 0.641 s

B. The role of the moon is greater than that of the sun in the occurrence of tides. ???​
ahrayia [7]

Our sun is 27 million times larger than our moon. Based on its mass, the sun's gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth. If tidal forces were based solely on comparative masses, the sun should have a tide-generating force that is 27 million times greater than that of the moon. However, the sun is 390 times further from the Earth than is the moon. Thus, its tide-generating force is reduced by 3903, or about 59 million times less than the moon. Because of these conditions, the sun’s tide-generating force is about half that of the moon.

Answer:

The Acceleration of the object = 6.4 m/s²

<u>Explanation:</u>

Mass of block (m) = 5 kg

Action force on block, (F₁) = 40 N

<u>To Find:</u>

Acceleration of the object (a) = ?

<u>Required solution:</u>

Frictional force opposing the motion (F₂) = 8 N

Here in this question we have to find Acceleration of the object. So, firstly we have to find Net force of block after that we will find Acceleration of the object on the basis of conditions given above

⇒ Net force = Action force on block - Opposing friction force

⇒ F = F₁ - F₂

⇒ F = 40 - 8

⇒ F = 32 N

Now, we have to two elements that used in formula, Net force and Mass of block.

Net force of the block (F) = 32 N

Mass of block (m) = 5 kg

And we have to find Acceleration of the object.

We can find Acceleration of the object by using the Second law of Newton which says F = ma

Here,

F is the Force in N.

m is the Mass in kg.

a is the Acceleration in m/s².

So let's find Acceleration (a) !

† From second law of Newton

⇛ F = ma

⇛ a = F/m

⇛ a = 32/5

⇛ a = 6.4 m/s²
