Answer:

Vf = ≈56.436 m/s

Explanation:

We'll need to use the equation:

Vf^2 = Vi^2 + 2aΔx

Plugging in what we know, we get:

Vf^2 = (0)^2 + 2(4.55)(350)

Finally, some algebra:

Vf^2 = 3185

Vf = ≈56.436

The electric field strength is defined as the ratio of electric force and charge. The electric field strength will be 2.8 ×10⁵ N/C.

The electric field strength is defined as the ratio of electric force and charge. The field's direction is determined by the direction of the force acting on the positive charge.

A positive charge produces a radially outward electric field, whereas a negative charge produces a radially inward electric field.

The given data in the problem is;

Q is the charge= 6. 4 × 10–7 C

E is the electric force=1. 8 × 10–1 N

The relation between the electrostatic force and the electric field due to a charge is given as:

[tex]\rm F_E=Q E \\\\ \rm E=\frac{F_E}{Q} \\\\ \rm E=\frac{1.8\times 10^{-1}}{6.4\times 10^{-7}} \\\\ \rm E=2. 8 \times 10^5\ N/C.[/tex]

Hence the electric field strength will be 2.8 ×10⁵ N/C.

Answer:

Honestly if I broke MY OWN record, I would be shocked.

Explanation:

Breaking your own record means either nobody has succeeded your record therefor its still YOUR record, or nobody had thought to even try to break your record. It would be great to push yourself to further limits and break a record you once made. You should be very proud if you did, because not only did no one break your record yet, you broke it yourself.

If putting yourself in Usain Bolt running shoes, when you break your own record, it either means that no one has ever beaten it.  

100 m in 9.58 seconds is the world record by Usain Bolt at the 2009 IAAF World Championships,

They predict that times will begin to plateau and that it will get harder and harder to beat the record.

Although the sub-nine seconds are on, they think: "It's safe to say that someone will break the nine-second barrier – not necessarily in our lifetime, but it will happen one day."

It would be fantastic to challenge yourself and surpass a previous record.

Therefore, if you did, you should be extremely proud because not only has no one else yet broken your record, but you also accomplished it yourself.

Answer:

The long term cost and benefit of renewable resources is that it is most likely a one-time purchase kind of thing. For example, if you use solar energy, you only have to buy the solar panels for your roof once. However, if you use gas oil to cook, you have to keep buying since it runs out. Sunlight doesn't run out.

The long term cost and benefit of non renewable resources is that it is something you can profit off of very easily. It will take a lot of time for people to completely switch over to renewable resources, so it is something that can steadily bring in money. Examples of non renewable resources that people constantly use is oil, gas, coal, etc.

Answer:

[tex]a=1.67\ m/s^2[/tex]

Explanation:

Given that,

Mass of the box, m = 6 kg

The net force acting on the box, F = 10 N

We need to find the acceleration of the box. We know that the force acting on an object is given by :

F = ma

a is the acceleration of the box,

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{10\ N}{6\ kg}\\\\a=1.67\ m/s^2[/tex]

So, the acceleration of the box is [tex]1.67\ m/s^2[/tex].

A is pulling the block straight down toward the center of the Earth, no matter what the slope of the plane may be. A is the force of gravity.

The directions of B and C both depend on the slope of the plane.

B is a force that's parallel to the plane, pulling the block UP the plane. B is the force of friction.

C is a force perpendicular to the plane, preventing the block from falling down through the plane. C is the normal force.

Answer:

1.17427...kg

Explanation:

Assumptions: no friction, no air resistance, no internal resistance, and it is 1 dimensional travel for velocity.

p=mv, where p is momentum, m is mass, and v is velocity

28.3=24.1(m)

divide both sides by 24.1

you get 1.174273859

Answer:

[tex]\boxed {\tt 1.17427386 \ kilograms}[/tex]

Explanation:

The formula for momentum is:

[tex]p=mv[/tex]

From this formula, we know that mass can be found by dividing the momentum by the velocity.

[tex]\frac{p}{v}=m[/tex]

The momentum is 28.3 kg m/s and the velocity is 24.1 m/s

[tex]p=28.3 \ kg \ m/s \\v=24.1 \ m/s[/tex]

[tex]\frac{28.3 \ kg \ m/s }{24.1 \ m/s} =m[/tex]

Divide. The meters per second or "m/s" will cancel each other out.

[tex]\frac{28.3 \ kg}{24.1} =m[/tex]

[tex]1.17427386 \ kg=m[/tex]

The mass of the object is 1.17427386 kilograms.

Answer:

The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. This is different from the tendency for a body to move, or translate, in the direction of the force. In order for a moment to develop, the force must act upon the body in such a manner that the body would begin to twist. This occurs every time a force is applied so that it does not pass through the centroid of the body. A moment is due to a force not having an equal and opposite force directly along it's line of action.

Imagine two people pushing on a door at the doorknob from opposite sides. If both of them are pushing with an equal force then there is a state of equilibrium. If one of them would suddenly jump back from the door, the push of the other person would no longer have any opposition and the door would swing away. The person who was still pushing on the door created a moment.

Answer:

C

Explanation:

Mass does not change with gravity, but weight DOES.   Higher gravity means MORE weight.

Answer:

D.

Explanation:

Weight is determined using the formula [tex]w=mg[/tex] (m=mass, w-weight, g=gravity​). In physics, weight is the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity.

Force is studied by physics and according to it four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

It is that magnitude that affects a body and is responsible for changes in its state of motion, according to quantum mechanics ordered from weakest to strongest are:

Therefore, we can conclude that four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

Answer:

Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons.
