Answer:
The electric force decrease as the distance increase and vice versa
As it obeys inverse square law that states ththaforce is inversly proportional to square if distance
so if the distance increased to twice the force will be decreased to quarter.
And that is coloumb's law of electrostatic force:
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
F=k(Q1.Q2)/r2
So as you increase the distance between charged objects, Force(attraction/repulsion) weakens by the square of their distance.
As you decrease the distance between charged objects, Force strengthens by the square of their distance.
Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. Electrical forces are extremely sensitive to distance. These observations are commonly made during demonstrations and lab experiments. Consider a charged plastic golf tube being brought near a collection of paper bits at rest upon a table. The electrical interaction is so small at large distances that the golf tube does not seem to exert an influence upon the paper bits. Yet if the tube is brought closer, an attractive interaction is observed and the strength is so significant that the paper bits are lifted off the table. In a similar manner, charged balloons are observed to exert their greatest influence upon other charged objects when the separation distance is reduced. Electrostatic force and distance are inversely related.
The pattern between electrostatic force and distance can be further characterized as an inverse square relationship. Careful observations show that the electrostatic force between two point charges varies inversely with the square of the distance of separation between the two charges. That is, the factor by which the electrostatic force is changed is the inverse of the square of the factor by which the separation distance is changed. So if the separation distance is doubled (increased by a factor of 2), then the electrostatic force is decreased by a factor of four (2 raised to the second power). And if the separation distance is tripled (increased by a factor of 3), then the electrostatic force is decreased by a factor of nine (3 raised to the second power). This square effect makes distance of double importance in its impact upon electrostatic

A boat trip travels are 15 miles in the direction of 45° east of north for an hour the boat then turn and travels at 18 m/s in a direction 5° north of East for an hour
Answer:
Hello your question is incomplete below is the missing piece
What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.
answer : 25.73 m/s
Explanation:
Given
V1 = 15 miles/hour = 6.71 m/s [ 45° EN ]
V2 = 18 m/s [ 5° NE ]
Calculate the resultant velocity
Vr = 6.71 m/s[45°] + 18m/s[5°].
Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )
Vr = ( 4.74 + 4.74 i )+ ( 17.93 + 1.57i) = 22.67 + 12.18i.
Therefore the magnitude
= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

What is the initial velocity of a projectile that is launched at a 25o angle and travles 70 km in 25 seconds?
Answer: The initial velocity of the projectile is 3.1 km/s
Explanation:
There is a problem with the question because we do not know in which direction the projectile travels 70 km.
I will assume that the projectile travels 70 km horizontally, as is the usual case.
I will also assume that 25 seconds after the projectile is fired, it hits the ground.
Suppose that the initial velocity of the projectile is V0, and this velocity V0 can be thought as the hypotenuse of a triangle rectangle, then the x-component and the y-component of the velocity will be the catheti of this triangle rectangle, then we can write:
Vy = V0*sin(25°)
Vx = V0*cos(25°).
Now, the vertical problem does not affect the horizontal one, so we can see only the horizontal case.
Here we don't have any force, then there is no acceleration, then the velocity is constant and it is equal to:
v(t) = V0*cos(25°)
For the horizontal position we can integrate over time to get:
p(t) = V0*cos(25°)*t + p0
where p0 is the initial position, and we can assume that it is equal to zero.
Then:
p(t) = V0*cos(25°)*t
Now we know that in t = 25s, the position is 70km
(because the projectile travelled 70km in 25 seconds) then:
p(25s) = 70km = V0*cos(25°)*25s
Now we can solve this for V0.
V0 = 70km/(cos(25°)*25s) = 3.1 km/s
The initial velocity of the projectile is 3.1 km/s
The thing you can get from this is that we can analyze the vertical problem and the horizontal problem separately (for example, here we only solved the horizontal case and we ignored the vertical one).

m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question the mass of an object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied is ,

500cm3 of water is to be jeated from room temperature 28oc to 100oc in order to prepare ahot cup pf coffee. What os the minimum heat required
Answer:
The minimum heat required is 171626 joules.
Explanation:
By First Law of Thermodynamics, the amount of heat ([tex]Q[/tex]), in joules, is equal to the change in internal energy of water. The minimum heat required is the sensible heat necessary to heat up the water. That is:
[tex]Q = \rho\cdot V \cdot c\cdot \Delta T[/tex] (1)
Where:
[tex]\rho[/tex] - Density of water, in kilograms per cubic meter.
[tex]V[/tex] - Volume of water, in cubic meters.
[tex]c[/tex] - Specific heat of water, in joules per kilogram-degree Celsius.
[tex]\Delta T[/tex] - Change in temperature, in degrees Celsius.
If we know that [tex]\rho = 1000\,\frac{kg}{m^{3}}[/tex], [tex]V = 5\times 10^{-4}\,m^{3}[/tex], [tex]c = 4186\,\frac{J}{kg\cdot ^{\circ}C}[/tex] and [tex]\Delta T = 82\,^{\circ}C[/tex], then the minimum heat required is:

What is the acceleration of an object that goes from 45m/s to 10 m/s in 5 seconds?
Answer:
[tex]\boxed {\boxed {\sf a= -7 \ m/s^2}}[/tex]
Explanation:
Acceleration is the change in velocity over time.
[tex]a= \frac {v_f-v_i}{t}[/tex]
The object accelerates from 45 meters per second to 10 meters per second in 5 seconds. Therefore,
[tex]v_f=10 \ m/s \\v_i= 45 \ m/s \\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a= \frac{ 10 \ m/s - 45 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac { -35 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= -7 \ m/s/s[/tex]
[tex]a= -7 \ m/s^2[/tex]
The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.
A nail is inserted in the trunk of a tree at a height of 1 meter from the ground
level. After 3 years, where will the nail be present?
Answer:
15m
Explanation:
Hello! first to solve this problem we must find that so much that the tree grew in the 15 years this is achieved by dividing the height of the tree before and after
the tree grew 10 times its initial length in 15 years, so to find how tall the nail is, we multiply this factor by 1.5m
X=(1.5m)(10)=15m
the nail is 15 meters above ground level
