Amanda studies a waveform. She labels parts of the waveform using variables (P,Q,R, and S), as shown in the image.
Which label part represents the wavelength

Answer:

False

Explanation:

velocity is more important than speed

Velocity is defined as the speed with direction.

This statement is true.

Velocity is different from speed look below at the differences.

Speed is defined as the ratio between distance over time while velocity is given as the ratio of displacement i.e. speed with direction over time.

Example: Velocity is the rate of motion, speed, or action. An example of velocity is a car driving at 75 miles per hour in the north direction.

Thus, the given statement is true.

Answer:

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.

First tell what are the directions and what we've to do?? add subtract or multiply??

Answer:

I believe the answer is 2.0

Explanation:

The net force that would be required is 2 N

From the question,

We have that

A net force of 10 N accelerates an object at 5.0 m/s².

To determine the net force that would be required to accelerate the same object at 1.0 m/s²,

First, we will determine the mass of the object

From the Newton's second law of motion, we have that

F = ma

Where F is the force

m is mass

and a is acceleration

From the given information

F = 10N

a = 5.0 m/s²

Putting the above parameters into the formula, we get'

10 = m × 5.0

∴ m = 10 ÷ 5.0

m = 2 kg

∴ The mass of the object is 2kg

Now,

For the net force that would be required to accelerate the same object at 1.0 m/s²,

Using the same formula

F= ma

Here,

a = 1.0 m/s²

and m = 2 kg

∴ F = 2 × 1

F = 2 N

Hence, the net force that would be required is 2 N

Answer:

Her linear velocity on the outer edge is 3 m/s

Her rotational velocity, is constant at 2 RPM

Explanation:

The given parameters are;

The radius of the rotating platform = r

The linear velocity  v(t) = 1 m/s

The position Emily is riding = 1/3 the distance from the center

The rotational velocity = 2 RPM = 2 Revolutions per minute

The formula for angular velocity, ω is given as follows;

ω = θ/t

Where;

θ = The angle rotated

t = The time taken for the rotation

Given that the rotational velocity = 2 RPM

1 revolution = 2·π radians

The angular velocity, ω = 2×π×(2 RPM) = 4·π rad/min = 4·π/60 rad/seconds

ω = 4·π/60 rad/seconds

The linear velocity, v = r₁×θ/t = r₁×ω

Where;

r₁ = 1/3 × r

v = 1 m/s = 1/3 × r  × 4·π/60 rad/seconds

∴ r = 1/(1/3 × 4·π/60) = 45/π meters

r = 45/π meters

Therefore her linear velocity, v₂ and her rotational velocity if she moves to the outer edge will be given as follows;

v₂ = r × ω = 45/π × 4·π/60 = 3 m/s

Her linear velocity on the outer edge, v₂ = 3 m/s

Her rotational velocity, remains at 2 RPM.

D. wood, hydrogen gas, milk, and water

Explanation:

Waves will transmit through wood, hydrogen gas, milk and water.

Waves are disturbances that propagates energy usually through a material medium.

Most mechanical waves pass through the given medium. Only electromagnetic waves do not really require a material medium for their propagation. They can be propagated through a vacuum.

Explanation:

Explanation:

Given parameters:

Mass of the car = 1500kg

Force applied  = 1000N

Acceleration  = 0.67m/s²

Unknown:

Proof that the acceleration will result from the applied force on the car

Solution:

According to newton's second law of motion,

       Force  = mass x acceleration

 So;

 Acceleration  = [tex]\frac{Force }{mass}[/tex]

Now insert the parameters and solve;

 Acceleration = [tex]\frac{1000}{1500}[/tex]   = 0.67m/s²

We have shown that the acceleration is 0.67m/s²

Answer:

The velocity of cart B after the collision is 1.29 m/s.

Explanation:

We can find the velocity of cart B by conservation of linear momentum:

[tex] p_{i} = p_{f} [/tex]

[tex] m_{A}v_{A_{i}} + m_{B}v_{B_{i}} = m_{A}v_{A_{f}} + m_{B}v_{B_{f}} [/tex]

Where:

[tex]m_{A}[/tex] is the mass of cart A = 600 g = 0.6 kg            

[tex]m_{B}[/tex] is the mass of cart B = 200 g = 0.2 kg

[tex]v_{A_{i}}[/tex] is the inital velocity of cart A = 0.7 m/s

[tex]v_{A_{f}}[/tex] is the final velocity of cart A = 0.27 m/s

[tex]v_{B_{i}}[/tex] is the initial velocity of cart B = 0

[tex]v_{B_{f}}[/tex] is the final velocity of cart B =?

Taking the left direction as the positive horizontal direction:

[tex] 0.6 kg*0.7 m/s + 0 = 0.6 kg*0.27 m/s + 0.2 kg*v_{B_{f}} [/tex]

[tex] v_{B_{f}} = 1.29 m/s [/tex]

Therefore, the velocity of cart B after the collision is 1.29 m/s.

Answer:

40.1m/s

Explanation:

This is a kinematics problem

x = 82m

a = -9.8m/s^2

v(initial) = 0

Find: v(final)

Using kinematics equation:

vf^2 = vi^2 + 2a(delta)x

vf^2 = 0 + 2*(-9.8)*(82)

vf = sqrt(1607.2) = 40.09m/s

The is traveling with a velocity of 40.1m/s when it hits the ground.
