The magnitude of the electric field will be 64.38 V/m. Mathematically, the electric field is found as the ratio of the voltage per unit length.
What is electric field?A physical field that surrounds electrically charged particles and exerts a force on all other charged particles in the field, either attracting or repelling them, is referred to as an electric field.
The magnitude of the electric field in terms of the pointing vector for this wave is found as;
[tex]\rm E_{MAX} = \sqrt{S \times c \times \mu_0 }[/tex]
Where,
E is the electric field
c is the speed of light
[tex]\mu_0[/tex] is the permeability
On Putting the given data ;
[tex]\rm E_{MAX} = \sqrt{11.0 \times 3 \times 10^8 \times 4 \times \pi \times 10^{-7}} \\\\\ \rm E_{MAX} =\sqrt{4144.8} \\\\ E_{MAX} =64.38 \ V/m[/tex]
Hence, the magnitude of the electric field will be 64.38 V/m.

When a star is so dense that its atoms have their electrons smashed in toward the nucleus (resulting in densities about a million times greater than water), the resulting material is called a Neutron star.
What is Star?Stars are present in the galaxy that have the ability to generate their own light. They are both quite hot and very huge.
They are largely formed of hydrogen, with a trace of helium thrown in for good measure.
The sun is also a star, and its energy and light play an important part in the survival of all kinds of life on Earth.

One positve and one negative charhe jave a force of -5. 00 N between them. If the force changed to -170 N , by what factor did the distance between them change
Answer:
The distance is shortenend by factor .1715
Explanation:
5 n = 1/r^2
sqrt (1/5) = r
170 n = 1 / ( x sqrt(1/5))^2
(xsqrt 1/5)^2 = 1/170
x sqrt 1/5 = .076696

A variable resistor has a voltage of 12.0 V placed across it. If the resistance is increased 20%, what happens to the current flowing through it
Answer:
Explanation:
Remark
The answer is in the formula
E = I * R
E = the voltageI = the CurrentR = the ResistanceSolution
Let the resistance = R
I = 12/R
If we increase the resistance by 20% then we get
R1 = R + (20/100) * R
R1 = R + 1/5 * R
R1 = 6 R/5
What happens to I when you do this
I = 12/(6/5 R) Effectively you need to treat 6/5 as a reciprocal
I = 12 * 5/6 * R
I = 10 / R
What does this tell you? Since the Resistance has a base value of R, when increased by 20%, the numerator of the fraction is reduced to 10 from 12. In other words the current is now smaller when R goes up.

When you travel in an elevator (which moves linearly in space), the ___________ detect when the elevator is accelerating or decelerating.
We can confirm that when you travel in an elevator, the utricle and saccule detect when the elevator is moving.
What are the utricle and saccule?These are small organs located in the inner ear. They serve a very important function in our everyday life. These otolith organs are responsible for the detection of movement and provide us with a sense of spatial orientation. They accomplish this by stimulating very small, hair-like cells with a specialized fluid.
Therefore, we can confirm that when you travel in an elevator, the utricle and saccule detect when the elevator is accelerating or decelerating.

What are the three equations of motion?There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
Note that these equations are only valid for a uniform acceleration.
where u and v are the initial and final velocity respectively
S is the total distance covered by the object
a is the acceleration of the object
As given in the problem a 1,500kg boulder falls off a 120m tall cliff on a planet that has a surface gravitational field of magnitude 3. 6 N/kg. Assume that the planet has no atmosphere
S = 120m, the initial velocity of the boulder is zero
u = 0
g = 3.6 m/s²
S = ut + 1/2at²
u= 0m/s , a= 3.6 m/s² and t = ? seconds
120 = 0×t + 0.5×3.6×t²
t² = 120 /(3.6×0.5)
t² = 66.667
t = 8.16 seconds
Thus, it would take 8.16 seconds for the boulder to strike the ground

Calories.
How high must the person climb? The
acceleration due to gravity is 9.8 m/s2 and 1
food Calorie is 103 calories.
Answer in units of km.
The height to which the weight-watcher must climb to work off the equivalent 991 (food) Calories is 0.59 Km
How to determine the energy.1 food calorie = 103 calories
Therefore,
991 food calories = 991 × 103
991 food calories = 102073 calories
Multiply by 4.2 to express in joule (J)
991 food calories = 102073 × 4.2
991 food calories = 428706.6 J
How to determine the height Energy (E) = 428706.6 JMass (m) = 73.9 kgAcceleration due to gravity (g) = 9.8 m/s²Height (h) =?E = mgh
Divide both side by mg
h = E / mg
h = 428706.6 / (73.9 × 9.8)
h = 591.95 m
Divide by 1000 to express in km
h = 591.95 / 1000
