A charge of 6. 4 × 10–7 C experiences an electric force of 1. 8 × 10–1 N. What is the electric field strength? 1. 1 × 10–7 N/C 3. 6 × 10–6 N/C 8. 2 × 100 N/C 2. 8 × 105 N/C.
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.
What is electric field strength?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.

Explanation:
2. A motorcycle starts at rest and moves a distance of 350 m. If it has a constant acceleration of 4.55m/s2, what is
its final velocity?
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
Which characteristic describes an organism of Kingdom Animalia when compared to plants?
A) It is able to move on its own.
B) Sunlight is used to make its own food.
C) Water is not needed for survival.
D) It does not need sunlight to survive.
Answer:
A
Explanation:
Because plants cant move and animals can.
The characteristic which describes an organism of kingdom Animalia is able to move on its own when compared to the plants kingdom. Thus, the correct option is A.
What are the characteristics of Animalia Kingdom?Animals are the multicellular, eukaryotic organisms in the biological kingdom Animalia. Animals are the organisms which consume organic material, breathe oxygen gas, are able to move on their own, can reproduce sexually and produce organisms which contain genetic information which is recombination of both the parents, and these organisms go through an ontogenetic stage in which their body consists of a hollow sphere of the cells, the blastula, during the embryonic development of organisms.
Organisms belong to Animal kingdom show some characteristics which are not found in the organisms which belong to the plant kingdom including movement. Animals can move on their own while plants cannot.
Therefore, the correct option is A.

Which represents the order of the forces from weakest to strongest.
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.
What is 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:
Gravitational force is the force exerted by one mass on the other, being a weak force.Weak nuclear force is the force responsible for radioactive decay.Electromagnetic force is the force that affects electrically charged particles and has two directions (attraction-repulsion).Strong nuclear force is the force that keeps the nuclei of atoms stable, being stronger than the electromagnetic force.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.

Put yourself in usual bolts running shoes-how would you feel about breaking your own world record ?
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.
What is the world record by Usain Bolt?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.

What is the mass of an object with a velocity of 24.1 m/s and a momentum of 28.3 kg m/s?
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.

1. A box with a mass of 6 kilograms is pushed with a net force of 10N to
the right on a frictionless surface. Calculate the acceleration of the box. *
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].

Scientists think that birds and other animals, such as sea turtles, may use Earth’s magnetic field to help them navigate. Research which animals might find their way using Earth’s magnetic field and investigate the evidence scientists have found that supports the idea. What would happen to the animal if Earth’s magnetic field were reversed?
Answer:
Magnetoreception (also magnetoception) is a sense which allows an organism to detect a magnetic field to perceive direction, altitude or location. This sensory modality is used by a range of animals for orientation and navigation, and as a method for animals to develop regional maps

predict the long term cost and benefit of using renewable or non renewable resources. please help will give brainliest
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.
What is the mass of an object that accelerates at "-1.56m/s" when pushed leftwards by a force of 300 N and has an opposing frictional force of 169 ?
The weight of an object can be determined by multiplying the mass of the object by which of the following?
A) the object's velocity
B) the object's size
C) the object's change in speed
D) the object's acceleration due to gravity
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.
