Work is equal to the magnitude of the force multiplied by the displacement x. Assuming Magali is pushing the phone, so that the force and displacement point in the same direction, then the work done is positive, and

2.7 J = (4.5 N) x   ==>   x = (2.7 J) / (4.5 N) = 0.60 m

Even if she was pulling the phone instead, the displacement would be the same, but the work done would be negative and the force would point in the opposite direction, thus also having a negative sign:

-2.7 J = (-4.5 N) x   ==>  x = 0.60 m

Answer:

2.4 secs.

Explanation:

Current (A) = Charge (coulomb)/Time(sec)

We are looking for time. So:

Time (sec) = Charge (coulomb)/Current (A)

Answer:

i) densidad

ii) conductividad eléctrica

Explanation:

Las propiedades características de una sustancia se denominan también propiedades intrínsecas. Estas son propiedades que no dependen de la cantidad de sustancia presente.

Las propiedades características se pueden utilizar para identificar una sustancia porque son propiedades que siempre debe exhibir la sustancia.

Entre las opciones, podemos encontrar las siguientes sustancias características;

i) densidad

ii) conductividad eléctrica

Explanation:

If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit. If this is the case, the satellite will move off into space. This occurs at speeds around or above 11,200 metres per second (m/s).

Answer:

The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

Answer:

W = 66 J

Explanation:

Given that,

The weight of the box, W = 44 N

It is placed on a shelf that is 1.5 m above the ground.

We need to find the work done in lifting the box.

We know that,

Work done, W = Fd

So,

W = 44 N × 1.5 m

= 66 J

So, the required work done is equal to 66 J.

Answer:

I. Stopping acceleration = 6 m/s²

II. Stopping distance, S = 75 meters

Explanation:

Given the following data;

Final velocity = 30 m/s

Time = 5 seconds

To find the stopping acceleration;

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

Substituting into the equation;

[tex]a = \frac{30 - 0}{5}[/tex]

[tex]a = \frac{30}{5}[/tex]

Acceleration = 6 m/s²

II. To find the stopping distance, we would use the third equation of motion;

[tex] V^{2} = U^{2} + 2aS [/tex]

Where;

V represents the final velocity measured in meter per seconds.

U represents the initial velocity measured in meter per seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

30² = 0² + 2*6*S

900 = 12S

S = 900/12

S = 75 meters

Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred. It is not energy but is often confused with energy.

[tex]n _{v} = \frac{c}{v} \\ = \frac{3 \times {10}^{8} }{2.30 \times {10}^{8} } \\ = 1.30[/tex]

This question involves the concept of refractive index.

The refractive index of the vinegar is "1.3".

The refractive index is defined as the ratio of the speed of light in air and the speed of light in the given medium which is vinegar here.

[tex]\eta = \frac{c}{v}[/tex]

where,

Therefore,

[tex]\eta = \frac{3\ x\ 10^8\ m/s}{2.3\ x \10^8\ m/s}[/tex]

η = 1.3

Answer:

So every hour he makes 10 miles.  So he would take 1 and a half hours to go to Mcdonalds 15 miles away.

Explanation:

[tex]\huge\boxed{{\textsf{90 minutes}}}[/tex]

We know that Mike's speed is [tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}[/tex] since there are [tex]60[/tex] minutes in an hour, and we know that MIke needs to travel [tex]15[/tex] miles. We'll model this using fractions:

[tex]\dfrac{10\ \text{miles}}{60\ \text{minutes}}=\dfrac{15\ \text{miles}}{x\ \text{minutes}}[/tex]

We can see that there is a [tex]2:3[/tex] ratio here, so we'll divide the left fraction by [tex]2[/tex] and multiply it by [tex]3[/tex] to get the right fraction.

[tex]\dfrac{10}{60}\Rightarrow\dfrac{5}{30}\Rightarrow\dfrac{15\ \text{miles}}{\boxed{90\ \text{minutes}}}[/tex]

C

Explanation:

Seat belts absorb kinetic energy when a car crashes because it pulls you back from falling forward given the kinetic energy (and momentum) you had before the crash.

Air bags absorb kinetic energy when a car crashes because it pushes you back from falling forward given the kinetic energy (and momentum) you had before the crash.

Crumple zones absorb kinetic energy when a car crashes because it provides a cushion when the cars crash. Kind of like dropping your phone into a pillow.

Answer:

3) Act on different objects

Explanation:

Newton's third law of motion states that for every action there is an equal and opposite reaction.

Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move, etc.

Basically, action-reaction force pairs are characterized by the following statements;

I. The forces are the same type such as magnetic force, contact force or gravitational force.

II. The forces are equal in magnitude but opposite in direction.

III. They act up on two different bodies.

Hence, the two forces that make up 3rd law of motion can act on different objects.

For example, while driving down the road, a bug strikes the windshield of a vehicle (Action) and makes a quite obvious mess in front of the face of the driver of the vehicle (Reaction) i.e the bug hit the vehicle and the vehicle hits the bug.

Answer:

I have a screenshot of this.

Explanation:

Answer:

Explanation:

In a velocity/time (aka acceleration) graph, the slope of a line indicates the value of the acceleration in m/s/s. Acceleration is the change in velocity over the change in time. From 0 - 2 seconds, there is no change in velocity, so the acceleration during this interval is 0 (which is the same as the slope of the line). From 2 - 4 seconds, the slope of the line is -2, so the acceleration during the time interval from 2 to 4 seconds is -2 (negative because David is slowing down but is still going the same direction: to the right).

Answer:

A. 59.4

Explanation:

The refractive index of the glass, n₁ = 1.50

The angle of incidence of the light, θ₁ = 35°

The refractive index of air, n₂ = 1.0

Snell's law states that n₁·sin(θ₁) = n₂·sin(θ₂)

Where;

θ₂ = The angle of refraction of the light, which is the angle the light will have when it passes from the glass into the air

Therefore;

θ₂ = arcsin(n₁·sin(θ₁)/n₂)

Plugging in the values of n₁, n₂ and θ₁ gives;

θ₂ = arcsin(1.50 × sin(35°)/1.0) ≈ 59.357551° ≈ 59.4°

The angle the light will have when it passes from the glass into the air, θ₂ ≈ 59.4°.

Answer:

ans: 6 m/s

Explanation:

spaceship 1 has mass= 150kg

initial momentum of spaceship 1 = 900 kg•m/s

we know,

momentum = mass × velocity

so,

velocity = momentum/mass

= 900 / 150

= 6 m/s

since we know it was initial momentum so, velocity is initial speed,

Explanation:

Potential energy is the energy occupied by an object or substance due to its position.

For example, a sled drops 20 meters in height on a hill shows that a decrease in height is taking place.

Hence, potential energy is involved there.

Kinetic energy is the energy acquired by an object due to its motion.

For example, a rider is going 20 m/s at the bottom of the hill shows that rider is in motion due to which it has kinetic energy.
