2 sfere electrizate cu sarcini egale,situate in vid la distanta de 10 cm una de alta,interactioneaza cu o forta de 0,1 N.Aflati sarcina electrica a uneia din sfere
Răspuns:
1,054 × 10 ^ -6Combombs
Explicaţie:
Conform legii coloumbs, forța de atracție sau repulsie între sarcină este exprimată ca;
F = kq1q1 / r²
F este forța atracției
q1 și q2 sunt taxele
r este distanța dintre sarcini
Deoarece taxele sunt egale, q1 = q2 = q
Ecuația devine
F = kq² / r²
Dat
F = 0,1N
r = 10cm = 0,1m
Necesar
q
Înlocuiți parametrii dați în formulă;
0,1 = 9 × 10 ^ 9q² / 0,1
0,1 × 0,1 = 9 × 10 ^ 9q²
0,01 = 9 × 10 ^ 9q²
q² = 0,01 / 9 × 10 ^ 9
q² = 0,01 / 9.000.000.000
q² = 1,11 × 10 ^ -12
q = √1.11 × 10 ^ -12
q = 1,054 × 10 ^ -6Combombs
Prin urmare, sarcina electrică pe una dintre sfere este de 1,054 × 10 ^ -6Combombs

c. replacement
d. exothermic
ADD ANSWER
+6 PTS
Answer:
a. endothermic
Explanation:
The reaction shown is an endothermic reaction. In such reaction, they require an input of energy.
Endothermic changes involves absorption of heat from the surrounding. The surrounding becomes colder at the end of the reaction. When heat is on the reactant side, it suggests a reaction that requires a considerable input of energy.Where does digestion begin?

A.
They cause the seasons to change.
B.
They cause the plates to move around.
C.
They cause the average global temperature to rise.
Answer:
C
Explanation:
The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.

A 1500 kg car is parked at the top of a hill 5.2 m high. What is the velocity of the car, in meters per second, when it reaches the bottom of the hill?
Answer:
Explanation:
The car will fall with acceleration due to gravity which is equal to 9.8 m /s²
For downward fall ,
initial velocity u = o
acceleration due to gravity = g = 9.8 m /s
final velocity v = ?
displacement h = 5.2 m
v² = u² + 2 gh
v² = 0 + 2 x 9.8 x 5.2
= 101.92
v = 10.1 m /s
The other name for 'net force' is 'unbalanced force'. What is the name of the force that could be applied to an object that would balance a net force and create a state of equilibrium?
Answer:
Friction
Explanation:
This is because friction tends to oppose the motion of an object. Since the unbalance force or net force causes a motion of the object, the frictional force would tend to oppose the object until it is large enough to balance the net force. When this is done, equilibrium is achieved.
At this instance, there is no net force acting on the object.
So, the forces on the object become balanced and in a state of equilibrium.
How long does it take for an 8 kg pumpkin to hit the ground if dropped from a height of 55 m.
Answer:
t = 3.35 s
Explanation:
It is given that,
Mass of a pumpkin, m = 8 kg
It is dropped from a height of 55 m
We need to find the time taken by it to hit the ground.
Initial velocity of the pumpkin, u = 0
Using second equation of motion to find it as follows :
[tex]h=ut+\dfrac{1}{2}at^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2(55)}{9.8}} \\\\t=3.35\ s[/tex]
So, it will take 3.35 seconds to hit the ground.

After carrying out a scientific investigation, Dr. Jones thinks she has just discovered new information about gravity. How should she best communicate her findings with other scientists? *
Post her discovery on the internet as fact.
Try to find new information on another topic.
Publish her discovery for other scientists to test.
Call her friends and tell them about the discovery
Answer:
Publish her discovery for other scientists to test.
Explanation:
In the context, Dr. Jones, a famous scientist conducted some experiment and has been working hard on it. She recently discovered some new information and facts about gravitation.
Now the best way to communicate and show her new discovery and results on gravity with the other scientist is to publish her findings in a famous science journal so that other scientist can work on it and make some test to find the same results.
By doing this, other scientist can work on her idea and she can tell and communicate her discovery with the other scientist and physicists.
As the frequency of a wave decreases, the wave's -
Answer:
When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true—as frequency decreases, wavelength increases.

A 1800 kg car moves along a horizontal road at speed v₀ = 18.4 m/s. The road is wet, so the static friction coefficient between the tires and the road is only µ static = 0.188 and the kinetic friction coefficient is even lower, µ kinetic = 0.1316. The acceleration of gravity is 9.8 m/s². What is the shortest possible stopping distance for the car under such conditions? (neglect the reaction time of the driver and round your answer to 4 decimal places)
Answer:
The shortest possible distance is [tex]|s| = 91.9 \ m[/tex]
Explanation:
From the question we are told that
The mass of the car is [tex]m = 1800 \ kg[/tex]
The speed along the horizontal road is [tex]v_o =u = 18.4 \ m/s[/tex]
The static friction coefficient is [tex]\mu_s = 0.188[/tex]
The kinetic friction coefficient is [tex]\mu_k = 0.1316[/tex]
Generally the static frictional force acting on the car is mathematically represented as
[tex]F_f = m * g * \mu_s[/tex]
Generally the force propelling the car is mathematically represented as
[tex]F = m * a[/tex]
Here a is the maximum acceleration
at the point which the car stops ,
[tex]F = F_f[/tex]
=> [tex]m * g * \mu_s = ma[/tex]
=> [tex]g * \mu_s =a[/tex]
=> [tex]a = 9.8 * 0.188[/tex]
=> [tex]a = 1.8424 \ m/s^2[/tex]
Generally from kinematic equation
[tex]v^2 = u^2 + 2as[/tex]
Here v is the final velocity of the car and the value is zero given that the car comes to rest
So
[tex]0^2 = 18.4^2 + 2* 1.8424 s[/tex]
=> [tex]s = - \frac{18.4^2}{2 * 1.8424}[/tex]
=> [tex]|s| = 91.9 \ m[/tex]
gold has a density of 19300 kg/m3 calculate the mass of 0.02m3 of gold in kilograms
Mass if a substance is the product of its volume and density. The mass of gold of 0.02 m³ with a density of 19300 kg/m³ is 386 kg.
What is density?Density of a substance is the measure of its mass per unit volume. Thus, it says how much denser the object is in a given volume. Density of a substance is dependent on its bond type, temperature and pressure beside the volume and mass.
Volume can be defined as the space occupied by the substance. Larger the volume , less dense the substance is. However as the mass increases volume also increases.
Mass of an object is the product of its volume and density.
Given the volume of gold = 0.02 m³
density = 19300 kg/m³.
mass = volume × density
= 0.02 m³ × 19300 kg/m³
= 386 kg
Therefore, the mass of gold is 386 Kg.
