A 4.03 x 10-5 F capacitor stores 5.15 x 10-3 J of energy. What is the voltage across the capacitor?
Answer:
V = 0.06255 Volts
Explanation:
Given the following data;
Capacitance = 4.03 * 10^{-5} F
Energy = 5.15 * 10^{-3} J
To find the voltage across the capacitor;
Mathematically, the energy stored in a capacitor is given by the formula;
E = ½cv²
Where;
C is the capacitor
E is the energy stored
v is the voltage.
Substituting into the formula, we have;
5.15 * 10^{-3} = ½ * 4.03 * 10^{-5} * v²
0.00515 = 0.00002015 * v²
V² = 0.00002015/0.00515
V² = 0.003912
Taking the square root of both sides, we have;
V = √0.003912
V = 0.06255 Volts

how do iquantum tunel through a wall and how long will it take me?
Answer:
The phenomenon known as "tunneling" is one of the best-known predictions of quantum physics, because it so dramatically confounds our classical intuition for how objects ought to behave. If you create a narrow region of space that a particle would have to have a relatively high energy to enter, classical reasoning tells us that low-energy particles heading toward that region should reflect off the boundary with 100% probability. Instead, there is a tiny chance of finding those particles on the far side of the region, with no loss of energy. It's as if they simply evaded the "barrier" region by making a "tunnel" through it.

What is the importance of centre of curvature in spherical mirror?
Answer:
Rays of light parallel to the principal axis of a concave mirror will appear to converge on a point in front of the mirror somewhere between the mirror's pole and its center of curvature. That makes this a converging mirror and the point where the rays converge is called the focal point or focus .

If the distance between the magnets tripled what would happen to the force between the 2 magnets?
Answer:
Our Repelling Force Magnet Calculator shows the repelling force on a magnet that happens when another magnet of the same size is placed at some distance from it, with like poles facing one another. The force depends on the distance between the magnets. The farther apart the magnets are, the weaker the force.

9. How is spring potential energy determined from a force versus position graph?
Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.
Explanation:
:)
By getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.
What will be the potential energy?As we know that potential energy is defined as the energy possessed by the body due to its position with respect to other positions.
For an example the potential energy of an object if it is placed at height h will be due to the gravitational acceleration of the earth and is given by [tex]PE=mgh[/tex]
Similarly, for a spring-mass system, the potential energy will be due to the weight of the mass that will be the force exerted by the mass on the spring so there will be an extension in the spring.
So this extension will be found out by the force and displacement graph as the position of the mass attached to the spring goes down so the potential energy can be calculated as the
[tex]PE= F\times X[/tex]
[tex]F=mg[/tex] weight of the mass
X= deflection of the spring
Thus by getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

A balloon with a charge of 4.0 x 10 -5C is held a distance of 0.10 m from a second balloon having the same charge. Calculate the magnitude of the repulsive force.
Answer:
1438.4 N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = Electrostatic force on the balloons, k = coulomb's constant, q = charge on the first balloon, q' = charge on the second balloon, r = distance between the two ballons.
From the question,
Given: q = q' = 4.0×10⁻⁵ C, r = 0.1 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( 4.0×10⁻⁵×4.0×10⁻⁵×8.99×10⁹)/0.1²
F = 14.384/0.01
F = 1438.4 N
The magnitude of the repulsive force will be 1438.4 N.Opposite charges repel each other by a force known as the repulsive force.
What is repulsive force ?The forces repel each other is known as the repulsive force.According to Coulomb's law, like charges repel each other.In Magnetism repulsive force between magnets of same orientation occurs.
The given data in the problem is;
q₁,q₂ is the charges =4.0 x 10 -5C 78
d is the distance = 0.10 m
F is the magnitude of the repulsive force=?
The magnitude of the repulsive force will be;
[tex]\rm F =\frac{ Kq_1q_2}{r^2} \\\\ \rm F =\frac{ 8.99 \times 1^9 \times 4.0 \times 10^-5 \times 4 \times 10^-5}{(0.10)^2} \\\\ \rm F =1438.4 N.[/tex]
Hence the magnitude of the repulsive force will be 1438.4 N.

What would be the effect of an increase in greenhouse gas concentration in the atmosphere on Earth's average temperatures?
Answer:
See Explanation
Explanation:
Greenhouse gases are those gases that are believed to trap infrared rays close to the earth surface. Infrared radiation is otherwise known as heat rays due its heating effect.
Increase in the concentration of these greenhouse gases will ultimately lead to a gradual increase in the earth's average temperature. This phenomenon is referred to as global warming.
The increase in volume of matter that occurs when matter is heated. a) Contraction b) Expansion c) kinetic energy d) Volume
Answer:
b) Expansion
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.
Generally, matter exists in three (3) distinct or classical phases and these are; solid, liquid and gas.
A physical change can be defined as a type of change that involves an increase or decrease in the volume of a physical object (object). Also, this change can be reversed to the original state under certain conditions.
The increase in volume of matter that occurs when matter is heated causes an expansion.
This ultimately implies that, when a physical object (matter) is heated for a specific period of time, it result in an increase in the volume of the object; this phenomenon is generally referred to as expansion.
On the other hand, a decrease in volume of a physical object (matter) as a result of heat is known as contraction.
When you are describing the rate that a race car goes around a track, should you use the term speed or velocity to describe the motion
Answer:
Speed
Explanation:
Speed is a description of how fast an object moves; velocity is how fast and in what direction it moves. In physics, velocity is the speed in a given direction.
Answer:
speed
Explanation:
Speed is a description of how fast an object moves; velocity is how fast and in what direction it moves. In physics, velocity is speed in a given direction. When we say a car travels at 60 km/h, we are specifying its speed. When we say a car moves at 60 km/h to the north, we are specifying its velocity.
