A 0.057 kg tennis ball and a tennis racket collide. The racket has an initial
momentum of -1.75 kg-m/s and a final momentum of -1.25 kg-m/s. The ball
has an initial momentum of 0.00684 kg-m/s. If you assume the collision is
elastic, what is the final velocity of the ball?
A. -0.50 m/s
B. -52.48 m/s
C. -2.99 m/s
d
D. -8.65 m/s

Answers

The answer is d I hope this helps

If we assume the collision to be elastic the final velocity of the ball will be  -8.65 m/s, therefore the correct option is D.

What is elastic collision?

It is a type of Collison for which the momentum, as well as the kinetic energy after and before the collision, is constant. there is no loss of energy in a perfectly elastic collision.

By using the law of conservation of momentum

momentum before collision = momentum after the collision

the initial momentum of rocket +initial momentum, of ball = final momentum of rocket + final momentum of the ball

By substituting the respective values

-1.75 + 0.00684 = -1.25 + m*v

-1.75 + 0.00684 = -1.25 + 0.057*v

v = -8.65 m/s

Thus, the final velocity of the ball is -8.65 m/s

Write the vectors labeled A, B and C with rectangular coordinates.

Answers

Focus on vector A. Start at the base of the vector which is at (1,1)

Then notice how we have to move 3 units to the right and 2 units up to get to the tip of the vector where the arrow is located. So this is at (4,3)

The fact that we moved 3 units to the right and 2 units up means that vector A is <3, 2>

So we'll type 3 in the first box and 2 in the second box.

======================================================

We use the same idea for vector B

Start at the base and move to the tip. Doing so has us move 1 unit left and 3 units down.

Vector B = <-1, -3>

We type -1 in the first box, and -3 in the second box.

======================================================

Finally onto vector C

Start at the base (0,0). To move to the tip, we need to go 3 units left and 3 units up

Vector C = <-3, 3>

-3 goes in the first box and 3 goes in the second box

======================================================

In general, vectors are useful to tell us a specific direction in which to go. They're useful in physics to determine how exactly a force is being applied, or how a particle is moving.

A mountain biker is climbing a steep 20° slope at a constant speed. The cyclist and bike have a combined weight of 800 N. What can you say about the magnitude of the normal force of the ground on the bike?

Answers

Answer:

Normal force = 751.75 N

Explanation:

It is given that,

The combined weight of the cyclist and the bike is 800 N

We need to find the magnitude of the normal force of the ground on the bike. It can be given by the formula as follows :

[tex]N=mg\cos\theta[/tex]

mg = W, combined weight of cyclist and bike

[tex]N=W\cos\theta\\\\N=800\times \cos(20)\\\\N=751.75\ N[/tex]

So, the magnitude of the normal force of the ground on the bike is 751.75 N.

The magnitude of the normal force of the ground on the bike is 751.752 N

The formula for that will be used to calculate the normal force of the ground on the bike is expressed as:

[tex]N= Fcos \theta[/tex]

F is the combined weight

[tex]\theta[/tex] is the angle of inclination

Given the following paramters

F = 800 N

[tex]\theta[/tex] = 20 degrees

Substitute the given parameters into the formula:

[tex]N=800 \times cos20^0\\N=800 \times 0.9397\\N=751.752N[/tex]

Hence the magnitude of the normal force of the ground on the bike is 751.752 N

Answers

If a wave is traveling at a constant speed, and the frequency increases, the wavelength would decrease.

What is wavelength?

The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave. The wavelength is the reciprocal of the frequency of the wave.

Wavelength λ = 1 / frequency

The wavelength and frequency are inversely related to each other. So, when frequency is increased, the wavelength increases.

A speed skater moving across frictionless ice at 8.8 m/s hits a 6.0 m -wide patch of rough ice. She slows steadily, then continues on at 5.8 m/s . What is her acceleration on the rough ice?

Answers

Recall that

v² - u² = 2 ax

where u and v are initial and final velocities, respectively; a is acceleration; and ∆x is the distance traveled (because the skater moves in only one direction).

So we have

(5.8 m/s)² - (8.8 m/s)² = 2 a (6.0 m)

a = ((5.8 m/s)² - (8.8 m/s)²) / (12 m)

a = -3.65 m/s²

A power cycle operating between hot and cold reservoirs at 500 K and 300 K, respectively, receives 1000 kJ by heat transfer from the hot reservoir. The magnitude of the energy discharged by heat transfer to the cold reservoir must satisfy

Answers

Answer:

The value is [tex]Q_l \ge 600\ k J[/tex]

Explanation:

From the question we are told that  

   The temperature of  hot is  [tex]T_h = 500 \ K[/tex]

   The temperature of cold is  [tex]T_c = 300 \ K[/tex]

   The energy received is  [tex]E = 1000 \ kJ = 1000 *10^{3 } \ J[/tex]

Generally the maximum thermal  efficiency of the engine is mathematically represented as

     [tex]\eta = \frac{T_h - T_c}{T_h}[/tex]

=> [tex]\eta = \frac{500 - 300}{500}[/tex]

=> [tex]\eta = 0.4[/tex]

Generally the thermal  efficiency of the engine is  

   [tex]\eta_t = \frac{Q - Q_l}{Q}[/tex]

Here  [tex]Q_l[/tex] is the heat energy rejected

Generally the thermal efficiency must be less than or equal to the maximum thermal  efficiency

So

       [tex]\frac{Q - Q_l}{Q} \le 0.4[/tex]

=>    [tex]\frac{1000 *10^{3} - Q_l}{1000 *10^{3} } \le 0.4[/tex]

the change in inequality sign is because [tex]1000*10^{3}[/tex]  which was dividing started multiplying

=>    [tex]Q_l \ge 1000*10^{3} - 400*10^{-3}[/tex]

=>  [tex]Q_l \ge 600*10^{3} \ J[/tex]

=>  [tex]Q_l \ge 600\ k J[/tex]

Calculate the magnetic field at the center of a circular current loop of radius R divided by the magnetic field at a distance R away from a very long straight wire carrying the same current value I. (Note the loop and wire are not in electrical contact.)

Answers

Answer:

The magnetic field at the center of a circular current loop of radius R divided by the magnetic field at a distance R away from a very long straight wire carrying the same current value I is [tex]\pi[/tex] or 3.14

Explanation:

The magnetic field at center of a circular loop is given by

[tex]B = \frac{\mu _{o}I }{2R}[/tex]

Where B is the magnetic field

[tex]\mu _{o}[/tex] is the free space permeability constant ( [tex]\mu _{o}[/tex] = 4π × 10⁻⁷ N/A²)

[tex]I[/tex] is the current

and [tex]R[/tex] is the radius

For the magnetic field of a long straight wire, it is given by

[tex]B = \frac{\mu _{o}I }{2\pi R}[/tex]

Where B is the magnetic field

[tex]\mu _{o}[/tex] is the free space permeability constant ( [tex]\mu _{o}[/tex] = 4π × 10⁻⁷ N/A²)

[tex]I[/tex] is the current

and [tex]R[/tex] is the distance from the wire

Then, to calculate the magnetic field at the center of a circular current loop of radius R divided by the magnetic field at a distance R away from a very long straight wire carrying the same current value I, that will be

[tex]\frac{\mu _{o}I }{2R} \div \frac{\mu _{o}I }{2\pi R}[/tex]

= [tex]\frac{\mu _{o}I }{2R} \times \frac{2\pi R }{\mu _{o}I}[/tex]

= [tex]\pi[/tex]

(NOTE: [tex]\pi[/tex] = 3.14)

Hence, the magnetic field at the center of a circular current loop of radius R divided by the magnetic field at a distance R away from a very long straight wire carrying the same current value I is [tex]\pi[/tex] or 3.14.

Please mark me brainliest!

Hope this helped God bless :)

Soil formation occurs more swiftly in warm, humid areas than it does in cold or arid ones.One of the most crucial climatic variables for the formation of soil is rainfall. The breakdown of large soil particles into smaller ones is accelerated by creatures such as bacteria, plants, and animals.

What climates soil to form fastest?

The rate of chemical reactions is accelerated by rising temperature, which also accelerates soil formation. Faster plant and bacterial growth in warmer climates aids in the weathering of materials and the formation of soils.

The formation of soil is another indirect effect of climate on organisms. Weathering is accelerated by precipitation and warm temperatures, which increases the amount of soil development. Rainfall increases the amount of organic matter, lowers pH, accelerates the leaching of basic ions, moves mud, etc.

Therefore, In warm, wet regions, soil development happens more quickly than in cold or arid ones. One of the most crucial climatic variables for the formation of soil is rainfall.

Explanation:

Use the equation for accelerated motion (g), and with zero initial velocity that doesn't include time:

[tex]v_f^2=v_i^2+2\,a\,\Delta x[/tex]

which for our case would reduce to:

[tex]v_f^2=v_i^2+2\,a\,\Delta x\\v_f^2=0+2\,9.8\,(91.5)\\v_f^2= 1793.4\\v_f=\sqrt{1793.4} \\v_f \approx 42.35[/tex]

Explanation:

To solve this problem we must use the superheated refrigerant table for refrigerant 134a. The attached image shows the specific volume and specific internal energy values for a pressure of 800 [kPa] and a temperature of 120 [°C].

m = mass =2 [kg]

the specific volume = v = 0.037625 [m³/kg]

The volume of the tank can be found using the following expression:

V = v*m

V = 0.037625*2 = 0.07525 [m³]
