Answer: The fuel pushes on the launch pad.

Explanation: This is a case of Newton's Third Law of Motion which states for every action in nature, there is an opposite and equal reaction.

Inside the rocket, the fuel is combusted creating a force that exerts on the launch pad by pushing it. As a reaction, the pad pushes the rocket upward, allowing it to go up. This is an example of Newton's Third Law of motion.

Answer:

Explanation:

given:

distance = 270 km

speed = 85 km/h

find:

how long does it take to get into his audition in hours?

solution:

velocity = distance / time

85 km/h =  270 km  

                      t

85 (t) = 270

t = 270 / 85

t = 3.176 hours

Answer:

its Force 1  is a contact force and Force 2 is a non-contact force.

Explanation:

I took the test!

Answer:

Force 1 is a contact force, Force 2 is a non-contact force :)

Explanation:

Because Force 1 is an object touching something and Force 2 is a force that is not touching something (hope this helps)

Answer:

Not gonna lie. I actually had to think about this a lot XD

Running in the rain can cause you to slip and get hurt. Which I think isn't what you would want.

Walking in the rain (although it is sad), is actually a better idea than running.

Hope this helps!

Answer:

Walk

Explanation:

Running might stop you from being outside for as long, but running on wet ground will most likely result in a not-so-graceful faceplant.

Answer:

Explanation:

From the question given above, the following data were obtained from:

Length of an axe = 20 cm

Width = 5 cm

Mechanical advantage (MA) =.?

The mechanica advantage is simply defined as the ratio of the length to the width of the axe. Mathematically, it is expressed as:

Mechanical advantage = length /width

With the above formula, we can obtain the mechanical advantage of the axe as follow:

Length of an axe = 20 cm

Width = 5 cm

Mechanical advantage (MA) =.?

MA = 20/5

MA = 4

Therefore, the mechanical advantage (MA) of the axe is 4

Explanation:

Answer:

They will move more slowly.

Explanation:

When the two objects stick together, they can be treated like one larger mass. By increasing mass, and keeping momentum the same, velocity must decrease (a larger object moves slower if all other variables stay the same) by p = mv.

Answer:

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density} \\ [/tex]

From the question we have

[tex]volume = \frac{20.2}{19.3} \\ = 1.04663212...[/tex]

We have the final answer as

Answer:

I believe whale fossils were found.

Answer:

Explanation:

Force = Mass * acceleration due to gravity.

Given

Mass of the paratrooper = 57kg

Acceleration due to gravity = 9.81m/s²

Required

Force pulling him down

Substitute unto formula;

F = 57 * 9.81

Force = 559.17 N

Hence the force pulling him down is 559.17N

The force pulling the paratrooper as he falls down is 558.6 N.

The given parameters;

The force pulling the paratrooper is force of gravity and the magnitude can be determined by applying Newton's second law of motion as shown below;

F = mg

F = 57 x 9.8

F = 558.6 N

Thus, the force pulling the paratrooper as he falls down is 558.6 N.

Answer:

The shape of the MASS vs ENERGY graph has a NON-LINEAR RELATIONSHIP.

Explanation:

Your Welcome Friend!   :)

A graph of kinetic energy vs the mass of an object is non-linear.

Changes in the output are not proportional to changes in any of the inputs in a nonlinear connection.

When a linear connection is plotted on a graph, it produces a straight line; however, when a nonlinear relationship is plotted on a graph, it produces a curve.

When graphed, motion energy is proportional to the mass of the moving item, resulting in a linear connection, and it expands with the square of its speed, resulting in a non-linear relationship.

Hence a graph of kinetic energy vs the mass of an object is non-linear.

Answer:

Explanation:

Average acceleration is how much the car increases (on average) per second.  So, since it increases by 30 m/s in 8 s, then dividing 30 by 8 will give you an average acceleration of 3.75 m/s^2 (remember that acceleration is ever increasing, so the unit is s^2, not just s)

Explanation:

The only thing that decreases the gravitational pull between 2 objects is if you increase the distance.

The formula is F = G*m*m/r^2

As r^2 gets larger and G and m1 and m2 remain the same, F has to get smaller because r^2 divides into G*m1*m2

Answer:

symbolic solution for the coefficient of friction between the baby and the sled is  

   [tex] \mu  =  \frac{m + M_s}{m}  *  \frac{a}{g}[/tex]

Explanation:

From the question we are told that

   The  mass of the boy is  [tex]M_e  =[/tex]

   The  mass of the shed is  [tex]M_s[/tex]

    The mass of the baby is  [tex]m[/tex]

    The  maximum acceleration for the baby to stay is  a

Generally the frictional  force between the baby and the shed is mathematically represented as

     [tex]F_f  =  \mu  N[/tex]

Here  N is the normal force acting on the baby which is mathematically represented as

     [tex]N  =  m *  g[/tex]

=>   [tex]F_f  =  \mu *  m *  g[/tex]

Now for the baby not the slip off the shed the frictional  force between the baby and the shed must be equal to the the force applied by the child

The force applied by the child is mathematically represented as

    [tex]F  =  [M_s+m] * a[/tex]

So

     [tex] \mu *  m *  g  =  [M_s+m] * a[/tex]

=>    [tex] \mu  =  \frac{m + M_s}{m}  *  \frac{a}{g}[/tex]
