Explain the advantages and disadvantages of having a racecar with a large mass in reference to Newton’s 1st law of motion. Use the term inertia in your answer.

Answers

Answer:

read the explanation

Explanation:

My answer to research question one is a car with a higher mass has more inertia than a car with a lower mass. A car with a higher mass needs more force to move than a car with a lower mass. The advantage of a car with greater mass is that it takes less impact when crash happens and has more protection.

The advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.

The disadvantage of a race car with large mass is that it will be difficult to get it start moving.

The Newton's first law of motion states that, an object in a state of rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.

This first law is also known as law of inertia because it depends on mass of the object.

Inertia is reluctance of an object to move or stop moving once it is in motion.

Thus, the advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.

The disadvantage of a race car with large mass is that it will be difficult to get it start moving.

Question 5: Which object traveled at a faster speed? (Make sure to show your
work!!)
Object A: 65 miles in 13 minutes
Object B: 125 miles in 25 minutes

Answers

Answer: objects A and B have the same speed.

Explanation:

Speed = distance divided by time.

Object A: 65 miles in 13 minutes

Speed (A) = 65 miles divided by 13 minutes

Speed (A) = 5 miles per minute

Object B: 125 miles in 25 minutes

Speed (B) = 125 miles divided by 25 minutes

Speed (B) = 5 miles per minute

Thus, objects A and B have the same speed.

When the comet passes close to the sun, it has a visible tail. Typically, the comet is only visible for a matter of days while it may be invisible for years. Why does the comet spend so little time close to the sun?

Answers

Answer:

The comet is locked in the Sun's gravity. as it falls deeper in the gravity we'll, its velocity increases. As is travels closer to the Sun, it is trying to break away, but cannot. This transforms into a sideways movement that produces a tight turn. It races further out of the gravity well, and sheds velocity.

What is the gpe of a rock weighing 100N that is sitting on top pf a hill 300 m high?

Answers

Answer:

Gpe = 30000J

Explanation:

Given the following data;

Weight = 100N

Height = 300m

To find the gravitational potential energy (gpe);

Gravitational potential energy can be defined as an energy possessed by an object or body due to its position above the earth surface.

Mathematically, potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where,

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Gpe = mgh

But weight = mg = 100N

Substituting into the equation, we have:

Gpe = 100*300

Gpe = 30000J

There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. If the brick is not moving on the scale, are the forces balanced or unbalanced?

Answers

Answer:

The forces are balanced

Explanation:

Since the brick is not moving on the scale, it means that the forces are balanced. An unbalanced force would only be present if there is motion of the brick. So, since the brick does not move, the net force on it is zero. Thus, the forces on it are balanced.

Identify the phase and division I or II for the following:
Metaphase II
Metaphase I
Telophase II
Cytokinesis

Answers

Answer:

Metaphase II

Explanation:

Metaphase II is the division of two daughter cells and is when sister chromatids line up in the middle of the cell.  This is what appears to be happening in the image.  Additionally, you can see that the chromosomes have already crossed over.  

Metaphase I only involves 1 cell, not 2 daughter cells.

Telophase II and Cytokinesis are when the cell splits.  Also, Telophase II would result in 4 daughter cells, not just 2.  

Consider the differences between a horseshoe magnet and a bar magnet. Is the attraction or repulsion going to be stronger or weaker between two horseshoe magnets or two bar magnets, as shown here? How would that influence the density of magnetic field lines?

Answers

Answer and Explanation:

A horseshoe-shaped magnet, that is, a "U" shape, has stronger attraction and repulsion capacities than that presented by a bar-shaped magnet. This is because the lines of the magnetic field on the "U" magnet are more dense and therefore promote a stronger magnetic field. This strong magnetic field exists because in a "U" shaped magnet, the magnetic poles are on the same plane, allowing a better fluctuation of the lines of the magnetic field.

if a person is 6.25 m away from a 60.0 w speaker, what is the sound level they are hearing?
(treat the speaker as a point source.)

Answers

Answer:

111dB

Explanation:

First, find the intensity of the sound using the formula I = Power / 4 x pi x radius ^2

So

60.0 / (4 x 3.14 (6.25)^2)

= 0.122

Then plug that into the equation to find sound level, which is 10log( I / Io)

Io being (1 x 10^-12)

So

10log(0.122 / 1 x 10^-12)

= 111dB

A box of books weighing 315 N is shoved across the floor by a force of 477 N exerted downward at an angle of 35° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.58, how long does it take to move the box 4.20 m starting from rest?

Answers

Answer:

It takes 1.14 s to move the box 4.20 m.

Explanation:

Using Newton's second law we have:

[tex]Fcos(35)-F_{f}=ma[/tex]

[tex]Fcos(35)-\mu mg=ma[/tex]

F is the force exerted and m the mass of the books

[tex]Fcos(35)-\mu mg=ma[/tex]

[tex]477cos(35)-(0.58*315)=\frac{315}{9.81}a[/tex]

So, the books accelerate at:

[tex]a=6.48\: m/s^{2}[/tex]

We know that the initial velocity is zero, so using the kinematic position equation, we have:

[tex]x=\frac{1}{2}at^{2}[/tex]

So, we just need to solve the equation for t.

[tex]4.2=\frac{1}{2}6.48t^{2}[/tex]

[tex]t=\sqrt{\frac{2*4.2}{6.48}}[/tex]

Taking the positive value of t:

[tex]t=1.14\: s[/tex]

Therefore, it takes 1.14 s to move the box 4.20 m.

I hope it helps you!
