By considering the derivative of q(t) with respect to time, it is possible to determine the current flowing through the element at t=0.5s. A current of -20e-0.5cos(250.5) + 200.5e-0.5sin(25*0.5) A would result.

By considering the derivative of the charge flow q(t) with respect to time, it is possible to determine the current flowing through an element at t=0.5s. The charge flow is represented by the equation q(t) = 20e-6t cos (25t) C. We may obtain the current passing through the element at time t=0.5s by differentiating the function q(t), which is equal to -20e-0.5cos(12.50.5) + 25e-0.5sin(12.50.5) A. The current flowing through the element at any one time may be calculated using this equation, which depicts the fluctuating rate of charge flow. A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control container is how it is calculated.

The sediment that will settle out of suspension last in a 100ml graduated cylinder is the one with the smallest particle size.

Suspended particles in a liquid settle out due to the force of gravity. The faster they settle, the heavier and coarser the particles are. In a 100ml graduated cylinder, the sediment with the smallest particle size will take the longest to settle due to its lower density and decreased settling velocity.

On the other hand, larger and denser particles will settle faster due to their increased weight and settling velocity. The time it takes for the particles to settle will also depend on the liquid's viscosity and the size and shape of the container. When choosing which sediment will settle out last, it is important to consider the properties of the particles and the conditions in which they are suspended.

The magnitude of the momentum of the two dice system is 0.003 kg m/s.

Momentum is a measure of an object's motion, defined as the product of its mass and velocity. It represents the amount of motion an object has, and the direction of that motion. In physics, momentum is a conserved quantity, meaning that the total momentum of a system remains constant unless acted upon by an external force. This is reffered to as the law of conservation of momentum. The greater an object's mass and velocity, the greater its momentum.

The magnitude of the momentum of an object can be calculated by multiplying its mass by its velocity.

For the blue die:

mass = 6.5 g = 0.0065 kg (converted from grams to kilograms)

velocity = 12 m/s

momentum = 0.0065 kg × 12 m/s = 0.078 kg m/s

For the green die:

mass = 7.5 g = 0.0075 kg (converted from grams to kilograms)

velocity = -10 m/s (opposite direction)

momentum = 0.0075 kg × -10 m/s = -0.075 kg m/s

The total momentum of the two dice system can be found by adding the momenta of each individual die:

total momentum = 0.078 kg m/s + (-0.075 kg m/s) = 0.003 kg m/s

So, the magnitude of the momentum of the two dice system is 0.003 kg m/s.

Explanation: another person explained it, but gave the wrong answer. i wish i knew what they did wrong.

When a cannon fires a cannonball, the cannon will recoil backward. It is because the momentum of cannonball and the cannon is conserved.

The conservation of momentum principle states that the amount of momentum within a problem domain remains constant; momentum is neither created nor destroyed, but only changed by the action of forces as described by Newton's laws of motion.

p: the system's initial momentum (total momentum before an event)

p′: the system's final momentum (total momentum after the event)

The total momentum is zero before the cannon is fired. This is due to the fact that neither object is moving. When a cannon is fired, the cannonball accelerates forward and the cannon accelerates backward. As a result, the total momentum of the cannon and cannonball after firing is also zero. Finally, it is obvious that a cannon will recoil backward when a cannon fires a cannonball because the momentum of the cannonball and the cannon is conserved.

The force experienced by a point charge in an electric field is given by Coulomb's law where F is the force, k is the Coulomb constant, q1 and q2 are the charges, and r is the separation between the charges.

The direction of the force is given by the direction of the electric field at that point, which is proportional to the gradient of the electric potential at that point. In this case, the arrangement of charges is symmetrical, with equal and opposite charges at each vertex of the square and a positive charge at the center. This means that the electric field at the center of the square will be zero, as the forces from each charge will cancel out. Therefore, the positive charge will not experience any net force and will remain stationary.

The speed of a ball that is thrown upward into the air, neglecting air resistance, changes over time due to the force of gravity. The ball's velocity decreases as it rises, reaches zero at the peak of its trajectory, and then increases as it falls back towards the ground.

The motion of an object under the influence of gravity can be described by the laws of physics. When a ball is thrown upward into the air, it initially moves with a certain velocity. However, as the ball rises, its velocity changes due to the force of gravity acting on it. In this answer, we will neglect the effect of air resistance and focus solely on the effect of gravity.

When a ball is thrown upward, it has an initial velocity, which is equal to the magnitude of the velocity with which it was thrown. This velocity is positive, meaning that it points in the upward direction. However, as the ball rises, it is slowed down by the force of gravity, which acts in the downward direction. As a result, the velocity of the ball decreases over time.

The acceleration due to gravity, g, is a constant 9.8 m/s^2, and it acts in the downward direction. The equation for velocity, v, as a function of time, t, can be expressed as v = v0 - gt, where v0 is the initial velocity. This equation shows that the velocity of the ball decreases linearly with time as it rises into the air.

At the peak of its trajectory, the ball has zero velocity. This means that it is momentarily at rest, and from this point on, it begins to fall back towards the ground. The velocity of the ball at this point is negative, meaning that it points in the downward direction. As the ball falls, its velocity increases due to the force of gravity, and it continues to increase until it reaches the ground.
