Answer:

F=10,000N

Explanation:

F=ma

m=5000kg

a=2m/s^2

[tex]F=(5000kg)*(2m/s^{2} )\\\\\\\\F=10000N[/tex]

Answer:

[tex]\boxed {\boxed {\sf 10,000 \ Newtons}}[/tex]

Explanation:

We are asked to find the force of Annabella's car when it hits a tree.

According to Newton's Second Law of Motion, force is the product of mass and acceleration.  Therefore, it is calculated using the following formula:

[tex]F=ma[/tex]

The mass of the car is 5000 kilograms and the acceleration is 2 meters per second squared.

Substitute the values into the formula.

[tex]F= (5000 \ kg)(2 \ m/s^2)[/tex]

Multiply.

[tex]F= 10,000 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton, so our answer of 10,000 kg*m/s² is equal to 10,000 Newtons.

[tex]F= 10,000 \ N[/tex]

Annabella's car hits the tree with a force of 10,000 Newtons.

Answer:

Radiation is the transfer of heat energy through space by electromagnetic radiation.

Explanation:

Hi there!

(A)

When the rock reaches the peak, it will have a vertical velocity of 0 m/s. We can use the equation:

vf = vi + at

vf = final velocity (0 m/s)

vi = initial velocity (2 m/s)

a = acceleration (in this situation, due to gravity = 9.8 m/s²)

t = time (s)

0 = 2 + (-9.8)t

2/9.8 = t = .204 sec

(B)

Use the equation:

d = vit + 1/2at²

d = 2(.204) + 1/2(-9.8)(.204²)

d = .204 m

Answer:

Refraction

Explanation:

Reflection involves a change in direction of waves when they bounce off a barrier.

Refraction of waves involves a change in the direction of waves as they pass from one medium to another.

The book's initial speed = 2.83 m/s

The mass of the textbook, m = 0.75 kg

The final speed of the textbook, v = 0 m/s (Since it comes to rest)

The distance covered by the book, d = 1.2 m

Coefficient of kinetic friction, [tex]\mu = 0.34[/tex]

The frictional force between the table and the book is calculated as:

[tex]f_k=-\mu mg\\\\ f_k=-0.34 \times 0.75 \times 9.8\\\\f_k=-2.499N[/tex]

The workdone by the textbook is calculated as:

[tex]W = Fd\\\\W=2.499(1.2)\\\\W=2.9988J[/tex]

According to the work-kinetic energy theorem:

Workdone by the book = Change in Kinetic energy

[tex]W = 0.5m(v^2-u^2)\\\\-2.9988=0.5 \times 0.75 \times (0^2-u^2)\\\\-2.99988=-0.375u^2\\\\u^2=\frac{-2.9988}{-0.375} \\\\u^2=7.9968\\\\u=\sqrt{7.9968}\\\\u=2.83m/s[/tex]

The book's initial speed = 2.83 m/s

Explanation:

(A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract.)

Answer:

air and water

Explanation:

The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through. The particles in a medium become disturbed and pass on this disturbance to the next one, and so on. So, the disturbance caused by the particles can travel through a medium such as air, ocean water, land, violin strings, Slinky coils, etc. Sound waves can travel through solids, liquids, or gases.
