Answer: The question is incomplete, options are not given and here are the options from another website.

A. Carpeted floor provide small impulse.

B. stopping time is shorter on the carpet.

C. stopping time is longer on the carpet.

D. carpet provides a smaller impulse and a longer time.

The correct option is C.

A wine glass may not break when it falls on carpet floor because the stopping time on carpet floor is longer to that of stone floor.

Explanation:

A wine glass may not break when it falls on carpet floor because the stopping time on carpet floor is longer to that of stone floor because the change in glass momentum is the same for both stone and carpet flow, therefore the impulses that is supplied by both carpet and stone floor is the same. Therefore,there is longer stopping time by the carpet floor because there is smaller force that act on it compared to stone floor which lead to less damage.

Explanation:

Newton's law of restitution states that when two bodies collide, the speed with which they move after the collision actually depends on the material from which they are made. The Coefficient of Restitution (e) tells us about the bounciness, or elasticity, of the collision.

Answer:

Fnet = 2782.6 N

Explanation:

        [tex]a = \frac{\Delta v}{\Delta t}[/tex]

        where Δv = vf - v₀ and Δt = tfi - t₀, replacing by the givens:

       [tex]\Delta v = v_{f} - v_{o} = 20 m/s - 29.8 m/s = -9.8 m/s[/tex]

       Δt = 4.9 s

       ⇒[tex]a = \frac{-9.8m/s}{4.9s} = -2 m/s2[/tex]

        [tex]F_{net} = m* a = 1391.1 kg * (-2 m/s2) = -2782.6 N[/tex]

Answer:Current across 10ohm, I =0.59 A

Explanation:

Total Resistance n parallel s given as

 1/Rt = 1/R1 + 1/R2 + 1/R3

1/Rt = 1/4 + 1/6 + 1/10

1/Rt = 0.51666

Rt = 1/0.51666

Rt = 1.935 ohms

 which is now connected In series with a ohm resstor

Rnet  in series = R1+ R2

Rnet = 1.935 + 2.0 = 3.935 ohms

Since a voltage of 12 V s connected with the resistors in series, we have that the net current flowing across the 2ohm and 1.935ohm will be

Current, I = Voltage, V/ Resistance, R net

I=  I2 / 3.935= 3.049 A

the Voltage across the 1.935 ohm resistance  

V= 1R

3.049  X  1.935  = 5.899 Volts

 remember that  1.935 ohm s the resultant resistance connected in parallel, therefore The voltage across the 1.935 ohm is same for the 10 ohm, 4ohm and 6ohm resistances

Therefore, the current passing through the 10ohm resistance will be

Current across 10ohm, I   = V/R = 5.899/10 = 0.5899 Ampere  ≈0.59 A

dawg im doin dat same quiz for ms matthews.

Explanation:

.

If the car is moving at a constant velocity, no force is acting on it therefore, there should be no arrows.

According to Newton's first law of motion which is also called the law of inertia, a body will remain at rest or in a state of uniform motion unless it is acted upon by a net force.

A car that is moving at constant velocity is in a state of uniform motion and this will not change unless the car is acted upon by a net force. No net force is acting on the car as long as it remains in a state of uniform motion hence the diagram is wrong. There should be no forward arrow in the diagram. The forces acting on the car are exactly balanced.

Explanation:

Answer:

v₁ = 17.1 cm/s

v₂ = 22.1 cm/s

Explanation:

From the principle of linear momentum, the momentum is conserved

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

where m₁ = mass of first object = 25.0 g

u₁ = initial velocity of first object = 20 cm/s

m₂ = mass of second object = 10.0 g

u₂ = initial velocity of second object = 15.0 cm/s

v₁ = final velocity of first object

v₂ = final velocity of second object

25 * 20 + 10 * 15 = 25 * v₁ + 10 * v₂

650 = 25v₁ + 10v₂ ----(1)

Also in an elastic collision, Kinetic energy is conserved and sum of initial and final velocities  is conserved

u₁ + v₁ = u₂ + v₂

20 + v₁ = 15 + v₂

v₂ = 5 + v₁

Substitute v₂ = 5 + v₁ in (1)

650 = 25v₁ + 10(5 + v₁)

90 = 25v₁ + 10v₁ + 50

35v₁ = 600

v₁ = 600/35

v₁ = 17.1 cm/s

Therefore, v₂ = 5 + 17.1 cm/s

v₂ = 22.1 cm/s

The motion with respect to the direction is called velocity. The change of velocity is known as acceleration.

According to the question. The value is as follows:-[tex]25 * 20 + 10 * 15 = 25 * v_{1} + 10 * v_{2}[/tex]

[tex]650 = 25v_{1} + 10v_{2} ----(1)[/tex]

Also in an elastic collision, Kinetic energy is conserved and the sum of initial and final velocities  is conserved

[tex]u_{1} + v_{2} = u_{1} + v_{2}[/tex]

After putting the value:- [tex]20 + v_{1} = 15 + v_{2}[/tex]

Hence:- v₂ = 5 + v₁

After solving both the equation, the value of V will be

v₁ = [tex]\frac{600}{35}[/tex]

Hence the value of V is  17.1 cm/s

Therefore, v₂ = 5 + 17.1 cm/s

v₂ = 22.1 cm/s

Answer:

The angular velocity of the tornado at its peak is 0.478 revolutions per second.

Explanation:

Let consider that tornado rotates at constant speed. From Rotation Physics we get the following relationship between linear ([tex]v[/tex]) and angular speeds ([tex]\omega[/tex]), measured in meter per second and radians per second, respectively.

[tex]\omega = \frac{v}{R}[/tex] (Eq. 1)

Where [tex]R[/tex] is the radius of the tornado, measured in meters.

If we know that [tex]v = 109.722\,\frac{m}{s}[/tex] and [tex]R = 36.5\,m[/tex], then the angular speed of the tornado at its peak is:

[tex]\omega = \frac{109.722\,\frac{m}{s} }{36.5\,m}[/tex]

[tex]\omega = 3.006\,\frac{rad}{s}[/tex] [tex]\left(0.478\,\frac{rev}{s} \right)[/tex]

The angular velocity of the tornado at its peak is 0.478 revolutions per second.

Complete question is;

A completely inelastic collision occurs between two balls of wet putty that move directly toward each other along a vertical axis. Just before the collision, one ball, of mass 3.0 kg, is moving upward at 20 m/s and the other ball, of mass 2.0 kg, is moving downward at 12 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)

Answer:

2.64 m

Explanation:

We are told the collision between the two balls is completely inelastic. This means that they will stick together after collision.

Since momentum is conserved and they stick together after collision, the formula for inelastic collision is;

m1•v1 + m2•v2 = (m1 + m2)v

Where v is the velocity after Collision.

We are given;

m1 = 3 kg

v1 = 20 m/s

m2 = 2 kg

v2 = -12 m/s (negative because it's moving downwards)

Thus, plugging into the equation, we have;

(3 × 20) + (2 × -12) = (3 + 2)v

60 - 24 = 5v

36 = 5v

v = 36/5

v = 7.2 m/s

To find the height that the combined two balls of putty rise above the collision point, we will use the formula;

v² = u² + 2gh

After the collision, initial velocity is the one they moved with after colliding. Thus, u = 7.2 m/s and final velocity is v = 0 m/s

Making h the subject and Plugging in relevant values, we have;

h = (v² - u²)/2g

Since gravity is acting in a direction opposite to the motion, then g = -9.81 m/s²

Thus;

h = (0² - 7.2²)/(2 × -9.81)

h = -51.84/-19.62

h = 2.64 m

Answer:

6.32m/s

Explanation:

Given parameters:

Initial velocity  = 4m/s

Acceleration  = 2m/s²

Distance covered  = 6m

Unknown:

Final velocity  = ?

Solution:

To solve this problem, we have to apply the appropriate motion equation;

         V²  = U² + 2aS

where V is final speed

          U is the initial speed

         a is the acceleration

          S is the distance

Insert the given parameters and solve;

      V² = 4² + 2 x 2 x 6

      V² = 16 + 24

      V² = 40

       V = √40 = 6.32m/s

Answer:

The total force on the charge placed in the middle will be zero (0).

Explanation:

The force on the charge in the middle of a square due to one of the charges placed at the square corner is given by:

[tex] F = \frac{KQq_{1}}{d^{2}} [/tex]

Where:

Q: is the charge in the middle = 1 nC

[tex]q_{1} = q_{2} = q_{3} = q_{4}[/tex] are the charge placed at the 4 square corners = -2 nC

The distance between the charge Q and q₁, q₂, q₃, and q₄ is:

[tex] d = \frac{\sqrt{2a^{2}}}{2} = \frac{\sqrt{2(1 cm)^{2}}}{2} = 0.707 cm = 7.07 \cdot 10^{-3} m [/tex]

Now, the magnitude of the force is:

[tex] |F_{Qq_{1}}| = \frac{KQq_{1}}{d^{2}} = \frac{9\cdot 10^{9}*1 \cdot 10^{-9} C*2 \cdot 10^{-9} C}{(7.07 \cdot 10^{-3} m)^{2}} = 3.60 \cdot 10^{-4} N = |F_{Qq_{2}}| = |F_{Qq_{3}}| = |F_{Qq_{4}}| [/tex]  

Since the magnitude of the force on the charge placed in the middle of the square is the same due to the 4 charges placed in the square corners (because the charge of q₁, q₂, q₃, and q₄ charges is the same) and due to the geometry, the vectorial sum of the total force on the charge placed in the middle will be zero (0).  

Therefore, the total force on the charge placed in the middle will be zero (0).          

I hope it helps you!
