Answer:

If you are traveling with a relativity constant velocity, then you will interpret your reference frame as being at rest. Since you are moving faster than the other train, the other train is moving backwards relative to you. Seeing the other train go past your window from front to rear makes it look like the train is going backwards

Answer:

An filtration is the answer.

The wire 2 has the most charge flowing in it at the given time interval.

The total charge flowing in each wire is calculated using the following equation;

Q = It

where;

The charge flowing in wire 1 is calculated as follows;

Q = 1 x 60 = 60 C

The charge flowing in wire 2 is calculated as follows;

Q = 2 x 45 = 90 C

The charge flowing in wire 3 is calculated as follows;

Q = 3 x 10 = 30 C

Thus, the wire 2 has the most charge flowing in it at the given time interval.

Answer:

f = 22.5 Hz

Explanation:

speed of wave = v

frequency = f

wave length = l

v = lf → f = v/l → f = 45/2 → f = 22.5 Hz

Answer:

12m/s

Explanation:

60/5=12

Answer:

Explanation:

Solution,

Distance(d)=60m

Time(t)=5sec

Now,

A.speed=d/t

A.speed=60/5=12m/s

Although we do not have the diagram needed to answer this question, we can provide general information in that electrical potential energy is calculated based on the charges and the distance between them.

This energy can be calculated using the value of the charges along with the distance between them with the formula Energy = [tex]k\frac{q1q2}{r}[/tex] in which q represents the charges whilst r represents the distance of separation. As we can see these values are inversely proportional to one another.

Therefore, we can confirm that we can calculate electric potential energy using the charges and the distance between them, which will be inversely proportional to one another.

Answer:

I would assume that the box slows down due to the frictional force between the floor and the box. In addition, the frictional force points opposite of the boxes motion. As we know, the box was given an initial speed, therefore, having an applied force. Hence, we can conclude that  the frictional force opposing the motion of the crate is equal to the applied force but acting in the opposite direction. This frictional force is called static friction. When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value.

Hope that helps!

Answer:

it increases

Explanation:

equal to opposite force so it would return the amount applied on it

If an object experiences a certain net force that causes a certain acceleration. If the net force on the object is tripled , then the acceleration of the object would become tripled as well assuming the mass of the object is constant.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem if an object experiences a certain net force that causes a certain acceleration. If the net force on the object is

tripled,

If a specific net force acting on an item results in a specific acceleration. Assuming the mass of the item remains constant if the net force acting on it is tripled, the acceleration of the object would also be tripled.

Thus, the acceleration of the object would get tripled.

Explanation:

Answer:

I choose red sea, because while diving, it will be more easier if the upward force is less(upthrust). since the upthrust increase with increase with density, it will be much difficult to dive in Dead sea than red sea.

1. since red sea has less density, it would have the minimum upthrust, which results in less resistance while diving.

it is also because, the pressure inside the liquid at same depth will be less in red sea, due to its density.

Answer:

280

Explanation:

I used the equation for momentum, p=mv

70 x 4 = 280

Given :-

To Find :-

Solution :-

For figure refer to attachment .

So the block will move if the angle of the inclined plane is greater than the angle of repose . We can find it as ,

[tex]\longrightarrow \theta_{repose}= tan^{-1}(\mu_s)[/tex]

Substitute ,

[tex] \longrightarrow \theta_{repose}= tan^{-1}( 0.2)[/tex]

Solve ,

[tex]\longrightarrow\underline{\underline{\theta_{repose}= 16.6^o }}[/tex]

Hence ,

[tex]\longrightarrow\theta_{plane}>\theta_{repose}[/tex]

Hence the block will slide down .

Now assuming that block is released from the reset , it's initial velocity will be 0m/s .

And the net force will be ,

[tex]\longrightarrow F_n = mgsin53^o - \mu_k N [/tex]

Substitute, N = mgcos53⁰ ( see attachment)

[tex] \longrightarrow ma_n = mgsin53^o - \mu_k mgcos53^o [/tex]

Take m as common,

[tex] \longrightarrow\cancel{m }(a_n) = \cancel{m}( gsin53^o - \mu gcos53^o)[/tex]

Simplify ,

[tex] \longrightarrow a_n = gsin53^o - \mu_k g cos53^o[/tex]

Substitute the values of sin , cos and g ,

[tex] \longrightarrow a_n = 10( 0.79 - 0.2 (0.6)) [/tex]

Simplify ,

[tex] \longrightarrow a_n = 10 ( 0.79 - 0.12 ) \\\\ \longrightarrow a_n = 10 (0.67)\\\\ \longrightarrow \underline{\underline{a_n = 6.7 m/s^2}}[/tex]

Now using the Third equation of motion namely,

[tex] \longrightarrow2as = v^2-u^2[/tex]

Substituting the respective values,

[tex] \longrightarrow2(6.7)(5) = v^2-(0)^2 [/tex]

Simplify and solve for v ,

[tex] \longrightarrow v^2 = 67 m/s\\\\\longrightarrow v =\sqrt{67} m/s \\\\\longrightarrow\underline{\underline{ v = 8.18 m/s }} [/tex]

Hence the velocity after covering 5m is 8.18 m/s .
