(a) The initial direction of the ball is horizontal.

(b) The time of flight of the ball is 0.65 s.

The initial direction of the ball is horizontal since the player catches the ball at the same level which implies that the speed of the of the ball was constant through out the motion.

The time of flight of the ball is calculated  using the following kinematic equation.

\(t = \frac{X}{v_x} \\\\t= \frac{4.6}{7.1} \\\\t = 0.65 \ s\)

The 5 Forces

Explanation:

The five forces that influence wind speed and direction are: Pressure gradient force (flow from high to low pressure) Coriolis force (apparent deflecting force due to the rotation of the Earth) Turbulent drag (Earth's surface or objects like trees or grass resist air flow and decrease wind speed near the ground)

Answer:

A. That enough light of any frequency would cause electrons to flow.

Explanation:

A P E X

Scientists using classical, Newtonian physics expect to observe the photoelectric effect because enough light of any frequency would cause electrons to flow.

When a medium receives electromagnetic radiation, electrostatically charged particles are emitted from or inside it.

The emission of ions from a steel plate when light falls on it is a common definition of the effect. The substance could be a solid, liquid, or gas; and the released particles could be protons or electrons.

Scientists using classical, Newtonian physics expect to observe the photoelectric effect because enough light of any frequency would cause electrons to flow.

The flow of the electron is a must to understand the photo electric effect.

The post-collision speed of the two players immediately after the tackle is 8.4 m/s.

Speed is the rate at which an object moves or an activity is performed. It can be measured in units such as meters per second, kilometers per hour, miles per hour, feet per second, or knots. Speed is the scalar quantity, which means it is determined based on the magnitude of a velocity and does not require the direction of motion to be specified.

Step 1: Calculate the Total Inertia

The total inertia of the two players before the collision can be calculated using the formula I = mv, where m is the mass and v is the velocity.

For the fullback: I = (100kg)(8 m/s) = 800 kg·m/s

For the defensive back: I = (75kg)(9 m/s) = 675 kg·m/s

Total Inertia = 800 kg·m/s + 675 kg·m/s =  1475 kg·m/s

Step 2: Calculate the Total Mass

The total mass of the two players is simply the sum of their individual masses: Total Mass = (100 kg) + (75 kg) = 175 kg

Step 3: Calculate the Post-Collision Speed

The post-collision speed of the two players can be calculated using the formula v = I/m, where I is the total inertia and m is the total mass.

v = (1475 kg·m/s) / (175 kg) = 8.4 m/s

Therefore, the post-collision speed of the two players immediately after the tackle is 8.4 m/s.

The minimum force required to move the block must be equal to the static frictional force between the block and the table. This force is given as:

F = Frictional Force

F = μs R

where,

F = Force required to move the block  = ?

μs = Coefficient of static friction = 0.74

Answer:

initial velocity=2.4m/s

Explanation:

Using the formula:

v=u+at

v= final velocity (6m/s)

u=initial velocity (???)

a=acceleration (0.2 m/s²)

t=time(18 seconds)

v=u+at

6=u+(0.2*18)

6=u+3.6

u=6-3.6

u (initial velocity)=2.4m/s

A boat in a race accelerates at 0.2 m/s² and with a final velocity of  6 m/s then the initial speed of the boat will be 1.67 m/s.

In mechanics, acceleration refers to the rate at which the velocity of an object changes in relation to time. The magnitude of accelerations as a vector. The acceleration of an object depends on the direction of the net force acting on it.

It is a vector quantity because acceleration has both a magnitude and a direction. Additionally, velocity is a vector quantity. The change in the vector of velocity during a period of time divided by the period of time is the definition of acceleration.

According to the question, the given values are :

Final speed, v = 6 m/s

Acceleration, a = 0.2 m/s²

Time, t = 18 s

Use the equation of motion :

v = u + at

6 = u + (0.2)18

u = 1.67 m/s

Hence, the initial speed of the boat is 1.67 m/s.

A current loop can be used to determine the presence of a magnetic field in a given region of space by measuring the induced electromotive force (emf) generated by the changing magnetic field.

Electromotive force (EMF) is the electrical energy produced by a source of energy such as a battery or generator. EMF is measured in volts and is the electrical potential that drives the current in an electrical circuit. The magnitude of the force is determined by the amount of energy that is being converted from one form to another. For example, a battery will convert chemical energy into electrical energy and the EMF is determined by the amount of energy that is being converted. This EMF is what powers electrical devices and is a measure of the potential energy that can be used. EMF can also be produced by the movement of charged particles such as when an electric current is produced through a wire. EMF can also be induced in a coil of wire when a magnetic field is placed near the coil.

A current loop can be used to determine the presence of a magnetic field in a given region of space by measuring the induced electromotive force (emf) generated by the changing magnetic field. This can be done by connecting a galvanometer to the current loop and then moving it around the region of space in question. If a magnetic field is present, the induced emf in the current loop will cause a deflection in the galvanometer, indicating the presence of a magnetic field.

The phase of the moon changes as it orbits around the Earth. It takes approximately 29.5 days for the moon to complete one orbit.

Therefore, if the moon is highest in the sky this morning at 6:00 am, one week from now it will be approximately halfway through its orbit. This means that the moon will be in its third quarter phase. During the third quarter phase, the moon appears as a half-moon in the sky with the right side illuminated.

This phase occurs when the moon is between the last quarter phase and the new moon phase. As the moon continues to orbit the Earth, it will eventually reach the new moon phase, where it appears completely dark in the sky. The cycle then repeats itself as the moon moves from new moon to full moon and back again. Understanding the phases of the moon can be helpful in planning outdoor activities and understanding the natural rhythms of the Earth and its satellite.

Explanation:

Pption d. flow does not independently influence the speed of water in a stream. Instead, it is an outcome determined by the combined effects of gradient, discharge, and channel geometry.

The flow itself, or the rate at which water moves in a stream, is not an independent factor that influences the speed of water in a stream. Instead, it is a result of other factors such as gradient, discharge, and channel geometry.

a. Gradient: The gradient, or slope, of the stream affects the speed of water. Steeper gradients generally lead to faster-flowing water.

b. Discharge: The discharge of a stream, which refers to the volume of water passing through a given point in a specified amount of time, directly affects the speed of water. Higher discharge results in faster flow.

c. Channel geometry: The shape and dimensions of the stream channel also influence the speed of water. Wider and deeper channels tend to have slower flow, while narrower and shallower channels often lead to faster flow.

Therefore, option d. flow does not independently influence the speed of water in a stream. Instead, it is an outcome determined by the combined effects of gradient, discharge, and channel geometry.

To derive the equations for shear force VV and bending moment MM for any location in the simply supported beam subjected to the given loading, we need to analyze the beam using the principles of statics. By applying equilibrium conditions, we can determine the variation of shear force and bending moment along the beam.

The shear force VV can be obtained by integrating the distributed load function. In this case, the shear force will be constant except at the point loads. Therefore, the shear force equation can be written as:

V(x)=−P1−P2for 0≤x≤aV(x)=−P1​−P2​for 0≤x≤a

V(x)=−P1−P2+RAfor a≤x≤LV(x)=−P1​−P2​+RA​for a≤x≤L

where P1P1​ and P2P2​ are the magnitudes of the point loads and RARA​ is the reaction force at support A.

The bending moment MM can be determined by integrating the shear force equation. The bending moment equation is given by:

M(x)=−P1x−P2xfor 0≤x≤aM(x)=−P1​x−P2​xfor 0≤x≤a

M(x)=−P1x−P2x+RA(x−a)for a≤x≤LM(x)=−P1​x−P2​x+RA​(x−a)for a≤x≤L
