Answer: Radio waves

Explanation:

Radio waves can travel through space. So, if you're wearing a space suit that contains a radio unit and one of your buddies sends you a radio message that there's pizza in the space station, you'd be able to hear it. That's because radio waves aren't mechanical -- they're electromagnetic. Electromagnetic waves can transmit energy through a vacuum.

8000 Joules is the amount of work required to haul up the equipment.

To calculate the work required to haul up the equipment, we need to consider two components: the work done against gravity and the work done against the weight of the rope.

The force due to gravity is given by the weight of the equipment, which is 100 N. The distance over which the force is applied is the height the equipment is being hauled, which is 40 meters. The work done against gravity can be calculated using the formula:

Work = Force × Distance

Work against gravity = 100 N × 40 m = 4000 N·m or 4000 J (Joules)

The weight of the rope can be calculated by multiplying the weight per meter (0.8 N/m) by the length of the rope (40 m):

Weight of the rope = 0.8 N/m × 40 m = 32 N

Since the rope is being hauled up, the work done against the weight of the rope is the same as the work done against gravity. Therefore, the work against the weight of the rope is also 4000 J.

The total work required to haul up the equipment is the sum of the work against gravity and the work against the weight of the rope:

Total work = Work against gravity + Work against rope weight

Total work = 4000 J + 4000 J

Total work = 8000 J

Therefore, it will take 8000 Joules of work to haul up the equipme

As the balls reach their maximum displacement, their kinetic energy reaches a minimum.  a maximum zero neither a maximum nor zero. This is because, at the maximum displacement point, the balls have come to a momentary stop and are changing direction, therefore their velocity is momentarily zero.

As kinetic energy is inversely related to the mass and velocity of an object, it will be zero if the velocity is zero. The balls' velocity and kinetic energy will rise once more when they start to move in the other direction. As a result, the kinetic energy is not at its greatest or its minimum at the moment of maximum displacement, but rather it is there.

The balls' kinetic energy depletes when they approach their maximum displacement. The balls' velocity is zero when they have reached their maximum displacement because they briefly stop traveling before turning in a new direction. A velocity of 0 yields zero kinetic energy because kinetic energy is computed as (1/2)mv2, where m represents mass and v is velocity.

Electric field lines are an excellent way of visualizing electric field. Electrical lines of force can be described as a way or path, it can be straight or curved so that the tangent gives the direction of the intensity of the electric field at that point at any point.

To raise the automobile with a hydraulic lift, a force of approximately 19,000 N must be applied to the piston.

In a hydraulic lift, the principle of Pascal's law is applied, which states that pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container. By utilizing this principle, a smaller force applied to a smaller piston can generate a larger force on a larger piston.

In this scenario, the force needed to lift the automobile can be calculated using the formula:

\(\frac{F_{1}}{A_{1}} =\frac{F_{2}}{A_{2}}\)

where \(F_{1}\) is the force applied to the piston, \(A_{1}\) is the area of the piston, \(F_{2}\) is the force generated on the larger piston (required to lift the automobile), and \(A_{2}\) is the area of the larger piston.

Given the radius of the shaft (small piston) as 0.08 m and the radius of the piston as 0.01 m, we can calculate the forces applied and generated as follows:

\(A_{1} = \pi (0.08)^2\\A_{2}= \pi (0.01)^2\)

\(\frac{F_{1}}{A_{1}} =\frac{F_{2}}{A_{2}}\)

Simplifying the equation and substituting the values, we can solve for \(F_{2}\):

\(F_{2}=\frac{F_{1}A_{2}}{A_{1}}\)

Plugging in the values, we find:

\(F_{2}=\frac{F_{1} \pi (0.01)^2 }{ \pi (0.08)^2} \\F_{2}= \frac{F_{1}\times 0.0001}{0.0064} \\F_{2}= 0.015625 \times F_{1}\)

Given that the mass of the automobile is 1520 kg and the acceleration due to gravity is \(9.8 \hspace m/s^{2}\), we can equate \(F_{2}\) to the weight of the automobile:

\(F_{2}= mg\\0.015625\times F_{1}= 1520\times 9.8\)

Solving for \(F_{1}\), we find:

\(F_{1}\approx \frac{1520\times 9.8}{0.015624} \\F_{1} \approx 19072 \hspace N\)

Therefore, a force of approximately 19,000 N must be applied to the piston in order to raise the automobile using the hydraulic lift.

Answer: 75m/s

Explanation:

First find the distance the first ball travels.

1/2*10*18^2 = 1620m

We know that both balls meet after 18s so they each have fallen 1620m when they meet. Second ball falls for 6 seconds less so it falls for 12s

plug this it kinematic equation.

1620 = v*12+1/2*10*12^2

1620 = v*12+720

900 = 12v

v = 75m/s

The elastic modulus parallel to the fibers of a composite material made of type E-glass fibers embedded in a matrix of ABS plastic, with all fibers to be aligned in the same direction can be calculated as follows:First, we need to calculate the elastic modulus of each component of the composite material.

The elastic modulus of type E-glass fibers is 72 GPa, and the elastic modulus of ABS plastic is 2.5 GPa.Next, we need to calculate the volume fraction of each component. If we assume that the composite material is made up of 60% type E-glass fibers and 40% ABS plastic, then the volume fraction of type E-glass fibers is 0.6, and the volume fraction of ABS plastic is 0.4.

Finally, we can use the rule of mixtures to calculate the elastic modulus parallel to the fibers. The rule of mixtures states that the elastic modulus of a composite material is equal to the weighted average of the elastic moduli of the individual components, where the weights are the volume fractions.

Therefore, the elastic modulus parallel to the fibers is given by:

Elastic modulus parallel to fibers = (Volume fraction of type E-glass fibers x Elastic modulus of type E-glass fibers) + (Volume fraction of ABS plastic x Elastic modulus of ABS plastic)

Elastic modulus parallel to fibers = (0.6 x 72 GPa) + (0.4 x 2.5 GPa)

Elastic modulus parallel to fibers = 43.5 GPaSo, the elastic modulus parallel to the fibers of the composite material is 43.5 GPa.

Part A:

The magnetic field is given by the formula:

F= qvBsinθ

where F is the magnetic force, q is the charge of the particle, v is the velocity of the particle, B is the magnetic field and θ is the angle between the velocity of the particle and the magnetic field.

The force on proton moving in the +x direction,

Fp = 2.06×10−16 N and the

velocity,  vp = 1.50 km/s = 1.5 × 10^3 m/s

Putting the values in the formula:

Fp= qvpBsinθp

2.06×10−16 = (1.60 × 10−19)(1.50 × 10^3)Bsinθp

where q is the charge of proton which is 1.6 × 10−19 C

The angle θp between the velocity and the magnetic field is 90° since the force is perpendicular to the velocity and the magnetic field.

Sin 90° = 1

Substituting the values, we get

B = 1.17 × 10−5 T

The magnitude of the magnetic field is 1.17 × 10−5 T

Part B:

The direction of the magnetic field can be obtained from the force on the electron moving in the -z direction and the force is given by

Fe = 8.60×10−16 N

and the velocity,

ve = 4.20 km/s = 4.2 × 10^3 m/s

Putting the values in the formula:

Fe= qveBsinθe8.60×10−16 = (1.60 × 10−19)(4.2 × 10^3)Bsinθe

where q is the charge of electron which is 1.6 × 10−19 C

The angle θe between the velocity and the magnetic field is 90° since the force is perpendicular to the velocity and the magnetic field.

Sin 90° = 1

Substituting the values, we get

B = 1.68 × 10−5 T

Since the force is in the +y direction and the velocity is in the -z direction, the magnetic field should be in the +x direction.

Therefore, the direction of the magnetic field is in the xz-plane.

Part C:

The magnitude of the magnetic force on an electron moving in the −y-direction at 3.50 km/s is given by the formula:

F= qvBsinθ

where F is the magnetic force, q is the charge of the particle, v is the velocity of the particle, B is the magnetic field and θ is the angle between the velocity of the particle and the magnetic field.

The velocity of the electron, ve = 3.50 km/s = 3.5 × 10^3 m/s

The angle between the velocity of the particle and the magnetic field is 90° since the force is perpendicular to the velocity and the magnetic field.

θ = 90° = π/2

Substituting the values in the formula:

F= qveBsinθF = (1.60 × 10−19)(3.5 × 10^3)(1.68 × 10−5) × 1F = 9.02 × 10−14 N

The magnitude of the magnetic force on an electron moving in the −y-direction at 3.50 km/s is 9.02 × 10−14 N.

Part D:

The direction of the magnetic force can be obtained from the right-hand rule. The direction of the magnetic force is perpendicular to both the magnetic field and the velocity of the particle.The velocity of the electron is in the -y direction and the magnetic field is in the +x direction. Using the right-hand rule, the direction of the magnetic force is in the +z direction.

Therefore, the direction of the magnetic force in the xz-plane is in the +z direction.

Most cells in an organism, such as leaf cells in a plant, are somatic cells. Somatic cells contain two sets of chromosomes, one inherited from each parent, and are diploid. In humans, for example, somatic cells contain 46 chromosomes, arranged in 23 pairs.

On the other hand, reproductive cells, such as sperm and egg cells, are sex cells or gametes. Gametes are haploid, which means they contain only one set of chromosomes, half the number found in somatic cells. In humans, gametes contain 23 chromosomes, which are not arranged in pairs.

The purpose of gametes is to combine during fertilization to produce a zygote, which contains a complete set of chromosomes (i.e., diploid). This ensures that the offspring will have genetic diversity and not be identical to either parent.

The process of reducing the number of chromosomes in gametes from diploid to haploid is called meiosis. Meiosis is a type of cell division that occurs only in gamete cells, and results in the production of four haploid daughter cells, each containing a unique combination of chromosomes.
