Answer:

50 represent the initial fee or cost added to the total cost

Explanation:

y=150x + 50

y represents the total cost and

x represents the number of hours she spends at the home.

Just like the slope intercept form y=mx + b; where m is the slope of the rate of  150 per hour and y is the total cost.

50 represent the initial fee or cost added to the total cost; in order words, 50 is the b value or where the cost is at 0 hours.

Y is what she charges just to make the trip and show up.

The patient owes her that 50 as soon as she rings the doorbell, before she spends any time there.

Answer:

The wedge balances propelled force.

Explanation:

According to the laws of motion, when appropriate weight is employed properly, a ball can move a truck. The same basic functions apply in this scenario. You often find a woodcutter raising the axe and letting it fall into the wood. This allows force to equally generate at both sides of the axe, splitting the wood apart.

Answer:

Kinetic energy depends on mass and speed (or magnitude of velocity).

K.E.  = 1/2 M S² or The amount of kinetic energy of a moving object has dependence on its  mass and its velocity.

Explanation: They are both right for a certain question

The kinetic energy of a moving object depends on its mass and velocity. The higher the velocity higher will be the kinetic energy. Mass also have the similar effect.

Kinetic energy of an object is the energy generated by virtue of its motion. When particles of an  object acquire much energy to overcome the intermolecular force, they gain kinetic energy to move apart.

Kinetic energy is related to the mass and velocity of the moving object. The expression relating kinetic energy with these parameters is written below:

Ke = 1/2 mv².

As per the relation, the kinetic energy of an object increases with an increase in mass or velocity or both. Hence, massive objects with greater velocity is having greater kinetic energy.

Explanation:

Given:

v₀ = 0 m/s

v = 40 m/s

t = 8 s

Answer:

Force = 533.33N

Explanation:

Given the following data;

Power = 40000watt

Velocity = 75m/s

To find the force;

[tex] Power = force * velocity [/tex]

Making force the subject of formula, we have;

[tex] Force = \frac {Power}{velocity}[/tex]

[tex] Force = \frac {40000}{75} [/tex]

Force = 533.33N

Answer:

TRUE

Explanation:

The answer is true.

Balance forces acting on a body will not change the motion of the body because the body experiences no net resultant force in one direction. When any body experiences equal forces with opposite directions, the net force or the resultant force experience by the body is zero.

In case of an unbalanced forces, there is a net force acting in one direction and so it causes the body to change in its state of motion in the direction of the net force.

Answer:

341.46miles

Explanation:

Find the diagram attachment.

To get the displacement D, we will use the cosine rule as shown;

D² = 200²+150²-2(160)(400)cos65°

D² = 40000+22500-128000cos65°

D² = 62500+54095.14

D² = 116595.14

D = √116595.14

D= 341.46 miles

Hence the plane final displacement is 341.46miles

Explanation:

Step one:

given data

mass of red cart m1=0.5kg

initial velocity u1 of red cart=50cm/s

mass of blue cart m2=0.5kg

initial velocity u2 of blue cart= 0cm/s

final velocity v2 of blue cart= 40cm/s

final velocity v1 of red cart= 10cm/s

Step two:

Momentum values red cart before and after the collision.

Before collision

P1=m1u1

P1=0.5*50

P1=25kg•cm/s

After collision

P2=m1v1

P2=0.5*10

P2=5kg•cm/s

Change in momentum= P1-P2=25-5= 20kg•cm/s

Momentum values blue cart before and after the collision.

Before collision

P1=m1u1

P1=0.5*0

P1=0 kg•cm/s

After collision

P2=m1v1

P2=0.5*40

P2=20kg•cm/s

Change in momentum= P1-P2=0-20= -20kg•cm/s

The total momentum of the system of the carts before collision is 25 kgcm/s.

The total momentum of the system of the carts after collision is 25 kgcm/s.

The change in momentum of the red cart is -20 kgcm/s.

The change in momentum of the blue cart is 20 kgcm/s.

The given parameters;

The momentum of the red cart before collision is calculated as follows;

[tex]P_r_1 = m_1u_1\\\\P_r_1 = 0.5 \times 50\\\\P_r_1 = 25 \ kgcm/s[/tex]

The momentum of the blue cart before collision is calculates as follows;

[tex]P_b_1 = m_2 u_2\\\\P_b_1 = 0.5 \times 0\\\\P_b_1 = 0 \ kgcm/s[/tex]

The momentum of the red cart after collision is calculated as follows;

[tex]P_r_2 = 0.5 \times 10\\\\Pr_2 = 5 \ kgcm/s[/tex]

The momentum of the blue cart after collision is calculated as follows;

[tex]P_2b_2 = 0.5 \times 40\\\\P_2b_2 = 20 \ kgcm/s[/tex]

The total momentum of the system before and after collision is calculated as follows;

[tex]P_1 = 25 \ kgcm/s \ + \ 0 = 25 \ kgcm/s\\\\P_2 = 5 \ kgcm/s \ + \ 20 \ kgcm/s = \ 25 \ kgcm/s[/tex]

The change in momentum of the red cart is calculated as follows;

[tex]\Delta P_r = Pr_2 - Pr_1\\\\\Delta P_r = 5 - 25 = - 20 \ kgcm/s[/tex]

The change in momentum of the blue cart is calculated as follows;

[tex]\Delta P_b = P_b_ 2 - P_b_1\\\\\Delta P_b = 20 - 0 \ = \ 20 \ kgcm/s[/tex]

Answer:

Explanation:

Given

Height S = 8.4m

Initial velocity u = 24m/s

Required

Time it will take to reach the ground

Using the equation of motion

S = ut +1/2gt²

8.4 = 24t + 1/2(9.8)t²

8.4 = 24t+4.9t²

4.9t²+24t - 8.4 = 0

Multiply through by 10

49t²+240t-84 = 0

Factorize

t = -240±√240²-4(49(-84)/2(49)

t = -240±√57600+16464/98

t = -240±√74064/98

t = -240±272.15/98

t = 32.15/98

t = 0.328seconds

Hence it takes 0.328seconds before it lands on the ground below.

b) The horizontal distance is the range expressed as;

R = u²/g

R = 27²/9.8

R = 729/9.8.

R = 74.39m

a. The time it took before the motorcycle stunt driver lands on the ground below is 1.31 seconds.

b. The distance from the base of the cliff that the motorcycle stunt driver traveled while in  the air is 31.44 meters.

Given the following data:

We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 [tex]m/s^2[/tex]

a. To determine how long (time) it took before the motorcycle stunt driver lands on the ground below:

At maximum height, time is given by the formula:

[tex]Time = \sqrt{\frac{2H}{g} }[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]Time = \sqrt{\frac{2\times 8.4}{9.8} }\\\\Time = \sqrt{\frac{16.8}{9.8} }\\\\Time =\sqrt{1.7413}[/tex]

Time = 1.31 seconds.

b. To determine how far (distance) away from the base of the cliff the motorcycle stunt driver traveled while in  the air:

[tex]Horizontal\;distance = horizontal\;speed \times time\\\\Horizontal\;distance = 24 \times 1.31[/tex]

Horizontal distance = 31.44 meters.

What does seafloor spreading result in?

Explanation:

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
