The drawing shows a 26.1-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, and , are applied to the crate, and it begins to move. The coefficient of kinetic friction between the crate and the floor is k = 0.347. Determine the (a) magnitude and (b) direction (relative to the x axis) of the acceleration of the crate.

Answer:

a. He wants to encourage Jack to actively listen and explore all solutions.

d. the manager wants to help Jack to understand the customs of other cultures.

Explanation:

As a front desk staff of the hotet, jack has to learn to activel listen, and explore all solutions available within his reach when deali with customers.

Because he is the first point of contact in the hotel as the front desk officer, this means he would get to interact with people of diverse cultures, customs e.t.c. Jack needs to learn and understand this cultures.

Answer: Heat

Explanation: All matter is made of tiny particles called atoms, molecules and ions. These tiny particles are always in motion – either bumping into each other or vibrating back and forth. It is the motion of particles that creates a form of energy called heat (or thermal) energy that is present in all matter

Answer:

a = 10/s^2

Explanation:

Answer:

a=10 m/s *2 right

Explanation:

The net force (0.5 kg) divided by the mass (5 N) = 10

The force moved the object to the right.

So you Would put this in the equation a=___ m/s *2 _____

And you would get a=10m/s*2 right

HOPE YOU LEARNED SOMETHING SO WHEN WE GO BACK TO SCHOOL YOU WILL KNOW WHAT YOU ARE TALKING ABOUT ! : )

Explanation:

Because

1 Kilogram:

The kilogram is defined as being equal to the mass of the International Prototype Kilogram (IPK), which is almost exactly equal to the mass of one liter of water.

1 Newton:

1 Newton in Earth gravity is the equivalent weight of 1/9.80665 kg on Earth. This is derived using Newton's second law f=ma and assuming Earth gravity of 9.80665 m/s2. 1 N (Earth) = 0.101971621297793 kg.

Answer:

The centripetal acceleration of the car is 50.4 m/s²

Explanation:

Given;

radius of the track, r = 0.3km = 300 m

constant angular acceleration, α = 4.5 x 10⁻³ rad/s²

during half of a lap, θ = π

Determine time of motion

θ = ωt + ¹/₂αt²

π = 0 + ¹/₂αt²

t² = 2π / α

t² = ( 2 x 3.142) / (4.5 x 10⁻³)

t² = 1396.44

t = √1396.44

t = 37.369 s

Determine the angular velocity

[tex]\omega_f = \omega_i + \alpha t\\\\\omega_f = 0 \ + \ 37.369*4.5*10^{-3}\\\\\omega_f = 0.168 \ rad/s[/tex]

Determine the centripetal acceleration of the car

[tex]\alpha _c = \omega^2 r\\\\\alpha _c = 0.168*300\\\\\alpha _c =50.4 \ m/s^2[/tex]

Therefore, the centripetal acceleration of the car is 50.4 m/s²

1. Electric generator

2. Using a battery powered torchlight

3. A fire(burning wood)

4. Electric lamp

5. Car using gas

Explanation:

Answer:

It would be 2N pointing South.

Explanation:

Since the forces are going in opposite directions, you can subtract them. Which makes it 7N south minus 5N North. That is 2N pointing South. Because the force going south is greater, it is the direction the force will be going.

Answer:

Explanation:

The distance covered by an object given it's velocity and time taken can be found by using the formula

From the question

average speed = 250 km/h

time = 2 hrs

We have

distance = 250 × 2

We have the final answer as

Hope this helps you

Answer:

The answer would be 454 miles.

Explanation:

You multiply the average speed by time travelled. Hope this helps!

Answer:

I=24,000 Amp

Explanation:

Electric Current

Is a measure of the quantity of charge Q flowing by a point in a time period of t.

The standard metric unit for the current is the Ampere, often abbreviated as Amps or A.

It can be calculated as:

[tex]\displaystyle I=\frac{Q}{t}[/tex]

The cloud generates a lightning strike that releases a charge Q=0.84 C during a time [tex]t=3.5\cdot 10^{-5}\ sec[/tex].

The current is of course, not of a constant value, but an average value can be calculated by using the above formula:

[tex]\displaystyle I=\frac{0.84}{3.5\cdot 10^{-5}}[/tex]

[tex]\boxed{I=24,000\ Amp}[/tex]

Note: I'm assuming the data 77.3 is the mass of the crate.

Answer:

[tex]\mu_s =0.36[/tex]

Explanation:

The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).

[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]

The normal force is numerical equivalent to the weight of the body if no other external forces are acting.

[tex]N=m\cdot g[/tex]

The mass of the crate is m=77.3 Kg, thus its weight and normal force is:

[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]

[tex]N= 757.54\ Nw[/tex]

Now we calculate the coefficient:

[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]

[tex]\boxed{\mu_s =0.36}[/tex]

Answer:

Frictional force. hope this helps have a good day

Answer:

frictional force

Explanation:

Friction always acts to oppose any relative motion between surfaces. For the simple example of a book resting on a flat table, the frictional force is zero. There is no force trying to move the book across the table, so there is no need for a frictional force because there is nothing for the frictional force to oppose.

Answer:

Is it a test

Explanation:

Answer:

Reasd through the explanartion first :)

Explanation:

Initial velocity, u = 30 m/s

Final velocity, v = 100 m/s

Acceleration, a = 40 m/s²

Distance traveled, s = ?

According to the 3rd equation of motion,

We know that,

v² - u² = 2as

So, putting all the values, we get

⇒ v² - u² = 2as

⇒ (100)² - (30)² = 2 × 40 × s

⇒ 10000 - 900 = 80s

⇒ 9100 = 80s

⇒ 9100/80 = s

⇒ s = 113.75 m.

Answer:

Latitude :

runs: east to west

measures : distances north and south of the equator

Longitude :

runs : north to south

measures : the distance east or west of the Prime Meridian

Responder:

Explicación:

Fuerza = Masa × aceleración

Dado que aceleración = velocidad final - velocidad inicial / tiempo

Fuerza = m (v-u) / t

Dado

Masa = 1000 kg

v = 15 m / s

u = 0 m / s

t = 20 segundos

Sustituye los valores dados en la fórmula para calcular la fuerza.

F = 1000 (15-0) / 20

F = 1000 (15) / 20

F = 15000/20

F = 750N

Answer:

Explanation:

Givens:

v = 15 m/s

t = 5 seconds

d = ??

Formula

d = v*t

Solution

d = 15 * 5

d = 75 m

Answer:

In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).
