Assuming all objects are moving with the same velocity, which statement describes the object with the smallest inertia?

Physics

RSB [31]4 years ago

Answer:

C. A pebble is thrown in space and continues in a straight line.

Explanation:

Here it is given that the property of inertia is totally depends on the mass of the object.

Here it is given that all the objects given here is moving with same speed

So here the speed will be same and we need to find the correct statement which will have least inertia.

So smallest inertia is corresponding to the smallest mass

So here we can say that the correct answer will be

C. A pebble is thrown in space and continues in a straight line.

Because rest other given examples are of more mass due to which they all have more inertia then pebble.

Also inertia does not depends on the speed so correct answer is as stated above

Answer:

C:A pebble is thrown in space and continues in a straight line.

Explanation:

Thanks for the question this one is quite simple actually.

In space since there is less gravity this means the small pebble with be slower (Small since the name of it is pebble and not rock).

Now it is asking us what the slowest inertia would be which this means speed

A: This is wrong because it is a car with a x velocity

B:This is also wrong because the bowling bar is also going x velocity as the car

D:An avalanche of snow goes down a STEEP hill with the same x velocity as everything else

C:This is the correct answer because the gravity in space is different and this makes the small pebble very slow inertia wise until it would reach something like Earth's atmosphere

Which of the following is true for valence electrons?
Debora [2.8K]

Answer:

<u>Valence electrons are always located in the outer most energy level.</u>

Explanation:

Valence electrons are the ones that are involved in chemical bonds. In order to take part in a chemical bonding, the outermost/valence electron needs to be involved. Thus, the answer is <u>Valence electrons are always located in the outer most energy level.</u>

A teacher sends her students on a treasure hunt. She gives the following instructions:
Norma-Jean [14]

Answer:

D) Joe need to walk 481 m in a direction 40.9° north of east

Explanation:

Given:

1. Walk 300 m north

2. Walk 400 m northwest

3. Walk 700 m east-southeast and the treasure is buried there

Taking north as positive y axis and east as positive x axis.

Resolving their positions into x and y vector components.

1. d1 = 300j

2. d2 = -400cos45i + 400sin45j

3 d3 = 700cos22.5i - 700sin22.5j

Resultant position.

d = d1+d2+d3

d = (-400cos45 + 700cos22.5)i + (300+400sin45-700sin22.5)j

d = (363.873)i + (314.964)j

D = √( (363.873)^2 + (314.964)^2)

D =481.25m ~= 481m

Angle = taninverse (314.964/363.873)

Angle = 40.9°

Since the x and y components are both positive, it implies that their position is north of east

Therefore, Joe need to walk 481 m in a direction 40.9° north of east

The wind direction changed from morning to night because  land and water absorbing solar energy unequally.

<h3>Convection current</h3>

Convection is said to occur when there is heat transfer by an actual movement of participles from place to place. The movement of air mass (wind) is affected by the relative amounts of solar energy absorbed by the land and sea.

Hence, the wind direction changed from morning to night because  land and water absorbing solar energy unequally.

Luke Autbeloe drops a pile of roof shingles from the top of a roof located 8.52
krek1111 [17]

Answer:

t = 1.31 s

Explanation:

Given that,

The top of a roof is located 8.52  meters above the ground.

We need to find the time required for the shingles to reach  the ground. Let the time be t. Its initial velocity was 0 as it was at rest initially. Using the equation of motion to find it as follows :

s=ut+\dfrac{1}{2}gt^2

Where

t is the time and u = 0

s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 8.52}{9.8}} \\\\t=1.31\ s

So, it will take 1.31 seconds for the shingles to reach the ground.
