Answer:
Explanation:
As we know by the theory of flux that if charge "q" is enclosed in a closed surface then total flux through the surface is given as
so here total flux passing through the cube is given as
now we will have
now as we know that charge is placed at the center of the cube
so the total flux is uniformly passing through all faces of the cube
so flux passing one side of the cube is given as
b. 2 times
c. 1/4
d. 4 times
Answer : The correct option is, (d) 4 times
Solution :
According to the Coulomb's law, the electrostatic force of attraction or repulsion between two charges is directly proportional to the product of the charges and is inversely proportional to the square of the distance between the the charges.
Formula used :
where,
F = electrostatic force of attraction or repulsion
= Coulomb's constant
and are the charges
r = distance between two charges
First we have to calculate the force exerted between S and q when the distance between the charge is 1 unit and let us assumed that the charge be 'q'
..........(1)
Now we have to calculate the force exerted between S and p when the distance between the charge is 2 unit at the same charge.
...........(2)
Equation equation 1 and 2, we get
Therefore, the force exerted between S and q is 4 times the force exerted between S and p.
I believe the answer is "4 times".
Answer:
1.) Oil and gas environment
2.) Mechanical engineering and electrical environment.
Explanation:
1.) Oil and gas environment.
Electricity and electric discharge are recognized as serious workplace hazard in oil and gas companies, exposing employees to burns, fires, and explosions.
2.) Mechanical engineering and electrical environment.
Electricity or electric discharge has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and explosions. Workers could die from electrocutions at work. This is
accounting for on-the-job fatalities and what makes these more tragic is that most of these fatalities could have been easily avoided.
If the speed of an object is tripled, its kinetic energy will be 9 times the initial value.
The kinetic energy of an object is the energy possessed by the object due to its motion.
K.E = ¹/₂mv²
where;
m is mass of the object
v is speed of the object
K.E = ¹/₂m(3v)²
K.E = 9(¹/₂mv²)
Thus, if the speed of an object is tripled, its kinetic energy will be 9 times the initial value.

The puck starts with velocity vector
Its velocity at time is
Over the 0.215 s interval, the velocity changes to
Then the acceleration must have been
which has a direction of about .
The direction of the acceleration is determined by the direction of the change in velocity. This would be calculated by subtracting the initial velocity vector from the final velocity vector. However, the calculation would involve complex trigonometric functions.
In order to find the direction of the acceleration, we need to calculate the direction of the change in velocity and that direction will be the direction of the acceleration.
To calculate the change in velocity, we subtract the initial velocity from the final velocity: (6.42 m/s, 50.0°) - (2.35 m/s, -22°). We then calculate the angle of this vector which represents the change in velocity, and hence the direction of acceleration.
However, this calculation is not straightforward because it involves vector operations and would require the use of trigonometric functions to solve. This is due to the fact that velocity is a vector, meaning it has both a magnitude and a direction. Consequently, this becomes a multi-step process involving trigonometry and physics.
