Answers

Given :

A ball strikes a wall. It exerts a force of 10 N to the left against the wall and bounces off.

To Find :

What force does the wall exert on the ball.

Solution :

We know, by third law of motion "every motion has equal and opposite reaction".

Ball exert a force of 10 N to the left against the wall.

So, by newton's third law of motion :

Wall will exert same force of 10 N in opposite direction i.e in right direction.

Therefore, force does the wall exert on the ball is 10 N to the right.

Hence, this is the required solution.

Answer:

10 N to the right

Water waves with a frequency of 4.5 Hz and a wavelength of 2.0m are traveling across a small harbor that is 200 m wide. How long does it take the waves to travel from one side of the harbor to the over?

Answers

Answer:

22.2 seconds

Explanation:

recall that for a regular wave

v = fλ

where v = wave velocity (we need to find this to solve the next part)

f = frequency = 4.5 Hz

λ = wavelength = 2.0m

Substituting these into the equation above,

v = fλ

v = (4.5)(2)

v = 9.0m/s

Also recall that Distance travelled = velocity x time

in our case, we found velocity above (= 9.0 m/s) and the distance across the harbor is given as 200m, hence

Distance travelled = velocity x time

200 = 9.0 x time

time = 200/9.0

time = 22.2 seconds

A) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a long distance.

B) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a short distance.

C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.

D) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a short distance.

Answer:

C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.

Explanation:

The correct answer is option C. This is because unlike in a pry bar, the effort force when swinging a baseball bat is larger and it is applied over a short distance; and in return the resisting force is smaller and it's applied over a long distance.

calculate the value of net force acting on given body?5N acting towards right & 15N force acting towards left on the brick.(draw fbd)
please help!!!!!​

Answers

Answer:

-10N to the left.

Explanation:

   The net force on a body is the single force that represent all the forces acting on a body.

 Let the right direction be positive

  Let the left direction be negative

Force acting to the right  = 5N

Force acting to the left  = -15N

Net force  = 5N + (-15N) = -10N

The net force will be directed -10N to the left.

A horse accelerates from rest for 1 s and covers a distance D. If instead the accelerates from rest with the same accelerations for 2 s will the distance it covers be equal to 2D, 4D, or 9D

Answers

Answer:

4D

Explanation:

We will use 2nd equation of motion in this question:

s = Vi t + (0.5)gt²

where,

s = distance covered

t = time taken

g = acceleration due to gravity

For t = 1 s:

s = D

Therefore,

D = (0 m/s)(1 s) + (0.5)g(1 s)²

D = 0.5g   -------------- equation (1)

For t = 2 s:

s = D

Therefore,

s = (0 m/s)(1 s) + (0.5)g(2 s)²

s = 0.5g(4)

using equation (1):

s = 4D

therefore, correct answer is:

4D

When a wire moves through a magnetic field, an electric current is produced in the wire. Why does this phenomenon occur?

Answers

Answer:

The negative charges and positive charges in the wire are pushed in the opposite directions by the magnetic field .

Explanation:

Hope this helps

When a wire moves through a magnetic field, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.

What is electromagnetic induction?

A magnetic field is a region in space where a magnetic force can be detected, so when a wire moves through a magnetic field, the magnetic force exerted on the wire generates a voltage, and the voltage creates an electric current in the wire. This electromagnetic induction phenomenon occurs because of the movement of charged particles within the wire, and this phenomenon can be explained by Faraday's Law of Electromagnetic Induction.

Hence, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.

A 3 kg rubber block is resting on wet concrete. The coefficient of static friction is 0.3. What is the minimum force that must be applied to the block to make the block begin to accelerate?

Answers

Answer:

You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)

We need to find the frictional force of the rubber block. This is the normal force (mass × gravity) multiplied by the coefficient of friction, which gives us a friction quantity of 8.82N. This is because it requires a force greater than 8.82N (Gravity is 9.8)

What is coefficient of friction?Mathematically, = F/N, where F represents the frictional force and N represents the normal force. Because F and N are both measured in force units (such as Newtons or Pounds), the coefficient of friction is dimensionless.The friction coefficient is the ratio of the frictional force resisting movement of two contacting surfaces to the normal force pushing the two surfaces together.Both F and N are measured in units of force (such as Newtons or Pounds), so the coefficient of friction is dimensionless. The coefficient of friction has different values ​​for static friction and sliding friction.In stiction, the frictional force resists the force applied to the object and the object remains stationary until the force of stiction is overcome. In kinetic friction, the frictional force opposes the motion of an object.

A paintball is fired horizontally from a tower 45 m above the ground. If the paintball gun fires at 90 m/s… How long does it take for the paintball to hit the ground? How far away from the tower will the paintball land?

Answers

Answer:

The time taken for the paint ball to hit the ground is [tex]t = 2.143 \ s[/tex]

The distance of the landing point from the tower is [tex]d = 192.86 \ m[/tex]

Explanation:

From the question we are told that

   The height of the tower is [tex]h = 45 \ m[/tex]

    The speed of the paintball in the horizontal direction is  [tex]v_x = 90 \ m/s[/tex]

Generally from kinematic equation we have that

      [tex]h = ut + \frac{1}{2} at^2[/tex]

Here u is the initial  velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally

         a is equivalent to [tex]g = 9.8\ m/s^2[/tex]

        t is the time taken for the paintball to hit the ground

   So    

       [tex]45 = 0* t + \frac{1}{2} 9.8 * t^2[/tex]

=>    [tex]t = 2.143 \ s[/tex]

Generally the distance of its landing position from the tower is

         [tex]d = v * t[/tex]

=>      [tex]d = 90 * 2.143[/tex]

=>    [tex]d = 192.86 \ m[/tex]

     

How should the student change the circuit to give negative values for current and
potential difference?

Answers

Answer:

changing the polarity or direction of the battery changes the sign of the voltage and the current

Explanation:

The sign of current and voltage are due to established conventions.

The way that a DC circuit with negative current values ​​is by changing the polarity of the power source or by inverting the battery, this creates that the electrons move in the opposite direction

Changing the battery also changes the direction of the power difference, since the potential from positive to negative, in most cases negative is assigned a potential of zero volts

In summary, changing the polarity or direction of the battery changes the sign of the voltage and the current

The motion of a car on a position time graph is represented with a horizontal tine What does this indicate about the car's motion?

Answers

Answer:

Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.

The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.

A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.

workdone = force × distance

From the question we have

workdone = 75 × 1.2

We have the final answer as

90 J

Hope this helps you

Answer:

[tex]\boxed {\boxed {\sf 90 \ Joules}}[/tex]

Explanation:

Work can be found by multiplying the force by the distance.

[tex]W=f*d[/tex]

The force of the package is 75 newtons.

The distance the package is lifted off the ground is 1.2 meters.

[tex]f= 75 \ N \\d=1.2 \ m[/tex]
