How do you find the magnitude simple?.

It's important to have a clear understanding of vector sum and trigonometry concepts to be able to determine the magnitude and coordinate direction angles of the resultant force.

The vector sum can be found by adding the vectors head-to-tail, which means that the tail of one vector is placed at the head of the next vector. The vector sum is known as the Resultant force.

To find the magnitude of the resultant force, we use the Pythagorean theorem, which states that the magnitude of the vector is equal to the square root of the sum of the squares of the vector's components. In other words,

|R| = √(Fx^2 + Fy^2 + Fz^2)

To find the direction angles of the resultant force, we use the trigonometric functions. The coordinate direction angles are the angles between the positive x, y, and z-axes and the projection of vector onto the xy, yz, and xz planes.

The angle with the x-axis is arctan(Fy/Fx)

The angle with the y-axis is arctan(Fz/Fx)

The angle with the z-axis is arctan(Fz/Fy)

It's worth noting that these angles are measured in a counterclockwise direction and that these angles are not unique, you can add or subtract multiples of 360° to get the same vector.

The average force exerted on the ball during the collision is 5.3 Newtons.

Force is a concept in physics that describes the interaction between two bodies. It is a vector quantity, meaning it has both a magnitude (amount of force) and a direction. Force can cause a change in an object's shape, speed, and direction of motion. Examples of forces include gravity, friction, tension, and electromagnetic forces. Forces can be used to push, pull, twist, and bend objects. Force is measured in newtons (N), and is the product of mass and acceleration. Force is an essential part of understanding the universe and how objects interact with each other.

Momentum is defined as mass multiplied by velocity,
and thus the initial momentum of the ball is 0.2 kg x 34 m/s = 6.8 kg m/s. After the collision, the momentum of the ball is 0.2 kg x 26 m/s = 5.2 kg m/s.
Thus, the change in momentum is 6.8 kg m/s - 5.2 kg m/s = 1.6 kg m/s.
The average force exerted on the ball during the collision can be calculated by dividing the change in momentum by the time of the collision:
Average force = 1.6 kg m/s / 0.3 s = 5.3 N.
This means that the average force exerted on the ball during the collision is 5.3 Newtons.

Yes, it is possible to draw a Gaussian surface to compute the electric field around a charged dipole.

To do so, draw a closed surface that encloses the charges of the dipole and apply Gauss' Law. This will allow you to calculate the electric field at any point on the surface.

The Gaussian surface should be chosen so that it encloses both charges from the dipole, and should be large enough to ensure that the electric field is uniform across the surface. The electric field can then be calculated by using Gauss' Law, which states that the total electric flux through the surface must be equal to the charge enclosed by the surface divided by the permittivity of free space.

The kinetic energy for the object which has a mass m of 10 kg with velocity of 1 m is 5 m/s.

The kinetic energy of an object increases with its mass. v indicates the object's speed. This relationship shows that an object's kinetic energy is inversely proportional to the product of its mass and velocity.

Possible justification: Because kinetic energy and speed have a strong relationship, an object's kinetic energy rises as its speed does.

The formula FG = mg relates an object's weight (FG) to its mass (m) and the acceleration due to gravity (g). The weight of an object is the force exerted on it by gravity and is measured in newtons (N). The mass of an object is a measure of its inertia, or the amount of matter it contains, and is measured in kilograms (kg). The acceleration due to gravity is a constant value that is approximately 9.8 m/s^2 on the surface of the Earth.

According to the formula, the weight of an object is directly proportional to its mass and the acceleration due to gravity. Therefore, if the mass of an object remains constant, any changes in its weight can only be caused by changes in the acceleration due to gravity.

For example, an object weighs 10 N on the surface of the Earth, but if you take it to a planet where the acceleration due to gravity is less, the weight of the object will decrease, even though its mass remains the same. The same applies to the opposite, If you take the same object to a planet where the acceleration due to gravity is higher, the weight of the object will increase, even though its mass remains the same.

In summary, the formula FG = mg shows that an object's weight is directly proportional to its mass and the acceleration due to gravity. If an object's mass remains constant, any changes in its weight can only be caused by changes in the acceleration due to gravity.

Four ways of solving an equation are 1) Graphical method 2) Elimination method, 3) Substitution method 4) Cross multiplication method

Graphical method: To solve linear equations graphically, first draw the graph for both equations in the same coordinate graph and locate the intersection point on the graph.

Elimination method: In this method, any of the coefficients is first eliminated by equating. After eliminating the coefficient, the equations are resolved to get the other equation. For example:

3x + 2y = 9 ———–(i)

x – y = 6 ———–(ii)

Here, if equation (ii) is multiplied by 3, the coefficient of “x” will become the equal and can be eliminated.

So, multiply equation (ii) × 3 and then subtract equation (i)

3x + 2y - 9 - 3x-3y-18 = 0

y = -9/5

Now, put the value of y = 1.8 in equation (ii).

So, x – 1.8 = 6

x = 4.2

Substitution method: To solve a linear equation using this method, first, take the value of one variable separately from any of the equations. Then, substitute the value of this variable in the second equation and solve it.

Cross multiplication method: Linear equations can be easily solved using this method. In this technique is used to simplify the solution. Following formula is used for solving 2 variable equation:

x /(b₁ c₂ − b₂ c₁) = y / (c₁ a₂ − c₁ a₁) = 1 /(b₂ a₁− b₁a₂)

The momentum of the van after the collision will be -9600 kg m/s.

Momentum is a concept in physics that is used to describe an object's resistance to changes in motion. It is based on the principle of inertia, which states that an object will remain in a state of rest or constant motion unless acted upon by an outside force. Momentum is calculated by multiplying the mass of an object by its velocity. Momentum is a vector quantity, meaning that it has both magnitude and direction. Momentum is also conserved, meaning that the total momentum of any closed system remains constant.

Momentum is a measure of an object's mass multiplied by its velocity. Before the collision, the momentum of the van was 9600 kg m/s (1200 kg x 8 m/s). After the collision, both vehicles will be travelling in the opposite direction, meaning that the momentum of the van will be the same as before, but in the opposite direction. Therefore, the momentum of the van after the collision will be -9600 kg m/s. The change in momentum, or delta momentum, of the van after the collision is the difference between the before and after momentum, or 9600 kg m/s.

Answer : Gretchen's rate of speed is 72.5 kilometers per hour.

What is the distance?

-- Distance is defined as the product of speed and time.

-- Since there are 3600 seconds in an hour, we can divide the time it takes -- Gretchen to travel 5500 meters by 3600 to find the number of hours it takes her:

⇒ 275 seconds / 3600 seconds/hour = 0.0763888889 hours.

Next, we need to convert the distance she travels to kilometers.

-- Since there are 1000 meters in a kilometer, we can divide the distance Gretchen travels by 1000 to find the number of kilometers she travels:

⇒ 5500 meters / 1000 meters/kilometer = 5.5 kilometers.

Now that we have the distance Gretchen travels and the time it takes her to travel that distance in the appropriate units, we can divide the distance by the time to find her rate of speed in kilometers per hour:
