Answer:

Explanation:

Let us calculate the time of flight first using the formula;

Velocity = Displacement/Time

Time = Displacement/speed

Time = 10.0/3

Time = 3.33secs

Next is to calculate how far out from the edge of the cliff it will hit the water. To get that, we will use the equation of motion;

S= ut+1/2gt²

u is the initial velocity = 0m/s

g is the acceleration due to gravity = 9.81m/s

S = 0 + 1/2(9.81)(3.33)²

S = 4.905*3.33*3.33

S = 54.39m

Hence it will hit the water at 54.39m from the edge of the cliff

Answer:

2 m/s

Explanation: Given that a flatbed car of a train moves 8 m/s to the east. A jogger runs along to top the flatbed car (which is not very safe) with a velocity of 6 m/s to the west.

Since the jogger is moving in an opposite direction to the direction of the train, and velocity is the distance covered in a specific direction, the jogger will be moving at a velocity relative to the velocity of the train.

Velocity = (8 - 6) m/s

Velocity = 2 m/s

Therefore, the jogger will be moving at the speed of 2 m/s

Based on the diagram above, the organisms that are shown are elephants.

A species simply refers to a biological classification of related organisms that have the same (similar) characteristics and they are capable of mating (breeding) with one another in a cycle (different seasons).

Based on the diagram above, we can logically deduce that the organisms shown are species of elephants and they look similar due to the following points:

However, an obvious difference between them is the number of tusk.

Answer:

From 9 to 10 sec the velocity is decreasing at a constant rate.

Change in V = 20 m/s - 30 m/s = -10 m/s

Since acceleration is constant from point E to point F (straight line)

and t = 9.5 sec is on this line

a = (20 m/s - 30 m/s) / 1 sec = -10 m/s^2  

The instantaneous acceleration of the object at time = 9.5 seconds is - 10 m/s².

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

From t = 9 second to t =10 second the velocity of the object decreases at a constant rate.

Change in velocity of the object = final velocity - initial velocity

= 20 m/s - 30 m/s

= -10 m/s

time interval is = 10 sec - 9 sec = 1 sec.

Hence, acceleration of the object is: a = Change in velocity/ time interval

= - 10 m/s/1s

= -10 m/s²

Therefore,  the instantaneous acceleration of the object at time = 9.5 seconds is - 10 m/s².

Hello. This question is incomplete. The full question is:

You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 29.7 N and the spring scale reads 17.6 N.

What is the magnitude of the force that Earth exerts on the bag?

Answer:

47.3 N

Explanation:

the entire system shown in the question above is at rest. Which greatly facilitates the calculation that we must do. In this case, to measure the magnitude that the force of the earth has on the backpack, you only need to add the two forces that you already know in the system.

In that case, it would be, you should calculate:

F= 29.7 N+ 17.6 N

F= 47.3N

Complete Question

A 95 kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant velocity. Find the coefficient of static friction and the coefficient of kinetic friction.

Answer:

The value for static friction is [tex]\mu_s = 0.60[/tex]

The value for static friction is [tex]\mu_k = 0.70[/tex]

Explanation:

From the question we are told that

The mass of the clock is [tex]m = 95 \ kg[/tex]

The first horizontal force is [tex]F _s = 560 \ N[/tex]

    The second horizontal force is    [tex]F _k  =  650  \  N[/tex]

Generally the static frictional force is equal to the first  horizontal force

So

     [tex]F _s  =  m  *  g  *  \mu_s[/tex]

=>   [tex]560  =  95  *  9.8  *  \mu_s[/tex]

=>    [tex]\mu_s =  0.60[/tex]

Generally the kinetic frictional force is equal to the second horizontal force

So

      [tex]F _k  =  m  *  g  *  \mu_k[/tex]

      [tex]650 =  95  *  9.8  *  \mu_k[/tex]

     [tex]\mu_k =  0.70[/tex]

Answer:

D. A Molecule

Explanation:

The smallest particle of a compound that still has the properties of the compound is a molecule. It is composed of two or more bonded atoms.

The smallest part of a chemical compound that has all the properties of that compound is a molecule (option d)

In the world of chemistry, substances are composed of tiny units called atoms, and these atoms bond together to form chemical compounds.

Option A, a nucleus, refers to the central core of an atom and consists of protons and neutrons. While essential for an atom, a nucleus alone does not represent a complete chemical compound.

Option B, a mineral, is a naturally occurring inorganic substance with a specific chemical composition and a definite atomic structure. However, minerals are not the smallest parts of a chemical compound.

Option C, an atom, is the fundamental building block of matter. It consists of a nucleus (containing protons and neutrons) surrounded by electrons. While atoms are crucial for forming compounds, they are not the smallest unit that retains all the properties of a compound.

Therefore, the correct answer is Option D, a molecule. A molecule is a group of two or more atoms bonded together, representing the smallest part of a chemical compound that possesses all the characteristics and properties of that compound.

Hence the correct option is (d).

velocity = displacement/time

The average velocity of the race car around the circular track in the given time is 62.8m/s.

Hence, option D) None of the above is the correct.

Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.

It is expressed as;

Velocity = displacement / time

It can also be expressed as;

Velocity = circumference / time = 2πr / t

Given the data in the question;

To determine the average velocity, we substitute our values into the expression above.

V = 2πr / t

V = ( 2 × 3.14 × 500m ) / 50s

V = 3140m / 50s

V = 62.8m/s

The average velocity of the race car around the circular track in the given time is 62.8m/s.

Hence, option D) None of the above is the correct.
