for each set of questions below think about which quantities cant change when a parallel plate is isolated

During Stanford University's "Search for Isolated Fractionally Charged Particles," more than 100 million more oil droplets were measured, hence option A is correct.

Theoretically, every charge must be a multiple of the charge of an elementary particle or an electron.

Similar automated equipment to that of Millikan and Fletcher was employed. No droplet with a fractional charge was discovered.

Therefore, even if the quantity used today for the elementary charge differs slightly from what Millikan and Fletcher measured, it is generally agreed that all charge is made up of multiples of the elementary charge.

Near the equator, energy is more readily emitted than absorbed. Near the poles, energy is mostly absorbed rather than radiated. In depth ocean currents, energy is transported from the equator to the poles.

Energy is described as the capacity to apply a force sufficient to move an object, or the capacity to "accomplish work." Despite the vagueness of the definition, the concept is actually quite straightforward: electricity simply denotes the force that drives objects. Potential energy falls into two distinct kinds.

The ability to work is the most fundamental definition of energy. Energy is what moves and transforms things. It is many in shape and is found everywhere. Food preparation demands energy.

The two methods most commonly used to limit the effects of indirectly transmitted x-ray photons are shielding and filtration.

Shielding is the process of placing materials between the x-ray source and the patient that absorb the x-ray photons, thus reducing the amount of radiation that reaches the patient. Common shielding materials include lead, tungsten, and concrete.

Filtration, on the other hand, involves the use of filters to reduce the energy of the x-ray beam by absorbing some of the lower-energy x-ray photons. These filters can be made of materials such as aluminum, copper, or polyethylene.

Both methods are effective at reducing the amount of radiation that reaches the patient and are used in combination to provide the greatest protection.

When a softball is thrown from an 80-meter-high building at a velocity of 10 meters per second, the height after t seconds is 148 feet.

Velocity is a vector representation of an object's or particle's displacement with respect to time. The meter per second (m/s) is the standard unit of velocity magnitude (also known as speed). Alternatively, velocity magnitude can be expressed in centimeters per second (cm/s). The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change. Speed is the pace at which an item moves along a route in time, whereas velocity is the rate and direction of movement. In other words, velocity is a vector, whereas speed is a scalar number.

The maximum height the ball will reach is the vertex of the parabola s(t)=48+80t-16t2. first, we need to solve for t. The vertex of any parabola of the form f(x)=ax2+bx+c is found by using x=-b/2a. In this case, x=t, b=80 and a=-16. Substituting we get:

]t=-80/((2)(-16)--->t=-80/-32--->t=5/2

Putting this value of t in the original formula will give us the maximum height:

1. The net force is 79.1°

The angle between those two forces is 120 degrees (because the triangle is equilateral) so the net force on particle 3 is the vector sum of the two forces.

The direction of the force on particle 3 due to particle 1 is along the line joining particles 1 and 3. The direction of the force on particle 3 due to particle 2 is along the line joining particles 2 and 3.

To find the net electric force acting on particle 3 due to particles 1 and 2, we can use Coulomb's law, which states that the force between two point charges is given by the equation:

[tex]F = k * (q1 * q2) / r^2[/tex]

where F is the force, k is the Coulomb constant [tex](8.99 x 10^9 N * m^2/C^2)[/tex], q1 and q2 are the charges of the two particles, and r is the distance between the two particles.

In this case, we have three particles placed at the corners of an equilateral triangle, with a side length of 3.1 cm. Since the triangle is equilateral, all three sides are equal in length, so r1 = r2 = 3.1 cm

The net force on particle 3 is the vector sum of the two forces acting on it due to particles 1 and 2.

F3 = F31 + F32 where F31 is the force on particle 3 due to particle 1 and F32 is the force on particle 3 due to particle 2

[tex]F31 = k * (q3 * q1) / r1^2[/tex]

[tex]F32 = k * (q3 * q2) / r2^2[/tex]

[tex]F31 = 8.99 x 10^9 N * m^2/C^2 * (8.0 nC * -8.4 nC) / (3.1 cm)^2[/tex]

[tex]F32 = 8.99 x 10^9 N * m^2/C^2 * (8.0 nC * -16.8 nC) / (3.1 cm)^2[/tex]

[tex]F31 = -9.52 * 10^{-4 N}[/tex]

[tex]F32 = -1.93 * 10^{-3 N}[/tex]

[tex]F3 = F31 + F32 = -2.88 * 10^{-3 N}[/tex]

After solving, The net force = 79.1°

The direction of the force on particle 3 due to particle 1 is along the line joining particles 1 and 3. The direction of the force on particle 3 due to particle 2 is along the line joining particles 2 and 3.

The angle between those two forces is 120 degrees (because the triangle is equilateral) so the net force on particle 3 is the vector sum of the two forces

2. Particle 3 will move in the direction of the net force acting on it, which is the vector sum of the two forces acting on it due to particles 1 and 2.

Since the net force is [tex]-2.88 * 10^{-3 N}[/tex], and the angle between the direction of the forces on particle 3 due to particles 1 and 2 is 120 degrees, particle 3 will move in the direction of the angle bisector of the angle between those two forces.

The angle bisector of 120 degrees is 60 degrees, thus the net force is acting on particle 3 at 60 degrees with respect to the positive x-axis.
