Answer:

Option A. 1 bar = 1 atm

Explanation:

Pressure has various units of measurement. Each unit of measurement can be converted to other units of measurement. For example:

1 atm = 1 bar

1 atm = 760 mmHg

1 atm = 760 torr

1 atm = 1×10⁵ N/m²

1 atm = 1×10⁵ Pa

With the above conversion scale we can convert from one unit to the other.

Considering the question given above, it is evident from the coversion scale illustrated above that only option A is correct.

Thus,

1 bar = 1 atm

Answer:

B: 50 N/m

Explanation:

Hopes it help.

The spring constant of the spring is 50 N/m. The correct option is B.

When the spring is compressed, it gets compressed up to its elastic limit. When load is removed from the spring, it regains its shape and obtains equilibrium position. The energy stored in this process is called as spring potential energy.

Given a spring has 100 J of EPE when it is stretched 2 m. The energy stored in the spring is given by

SPE = ½ kx²

100 = ½ k (2 m)²

k = 50 N/m

So, spring constant of the spring is 50 N/m.

Thus, the correct option is B.

Answer:

205N

Explanation:

The net force (F) is the difference between the applied force([tex]F_{A}[/tex]) and the kinetic frictional force([tex]F_{R}[/tex]). i.e

F = [tex]F_{A}[/tex] - [tex]F_{R}[/tex]    -----------------(i)

Note that;

[tex]F_{R}[/tex] = μmg

Where;

μ = coefficient of kinetic friction

m = mass of the body

g = acceleration due to gravity = 10m/s²

Equation (i) then becomes;

F = [tex]F_{A}[/tex] - μmg        -------------------(ii)

Given from question;

m = mass of motorcycle = 150kg

μ = 0.03

[tex]F_{A}[/tex] = 250N

Substitute these values into equation (ii) as follows;

F = 250 - (0.03 x 150 x 10)

F = 250 - (45)

F = 205N

Therefore, the net force applied to the motorcycle is 205N

Answer:

a. Increases

b. Two objects that have opposite charges

Explanation:

a. As the amount of charge on two objects increases, the strength of the electrical force between the objects increases. decreases. varies. remains the same.

According to Coulomb's law, the electrical force, F between two charges q and Q is directly proportional to the product of the charges.

So, F ∝ qQ

So, if q and Q increase, their product increases and thus, the strength of the electrical force between them increases.

So, if the amount of charge of two objects increases, the strength of the electrical force between the objects increases.

b. For which pair of objects would adding the same amount of electrons to each object result in a decrease in the electric force? two positively charged objects two negatively charged objects two objects that have no charge two objects that have opposite charges

Since according to Coulomb's law, the electrical force, F between two charges q and Q is directly proportional to the product of the charges.

So, F ∝ qQ

If the same amount of electrons are added to both charges and the charges are opposite in sign, the magnitude of one charge  increases while that of the other charge decreases. so the product qQ decreases and thus F decreases.

So, the electric force decreases when the same amount of electrons is added to two objects that have opposite charges.

Answer:

A increases

Answer:

Explanation:

Considering that this is parabolic motion, we know that the time the ball is in the air begins the instant it leaves the ground, reaches up to its max height, and then begins falling until it reaches the ground. Duh, right? Some important things happen during this trip. There are a few things we need to know in order to even begin the problem. Parabolic motion has x and y coordinates because it is 2-dimmensional; the acceleration in the x dimension is not the same as the acceleration in the y dimension; the velocity of an object at its max height is always 0; the time it takes to reach its max height (where the max height is half the distance the object travels) is half the time it takes to make the whole trip. Yikes. That's a lot to know and much to remember! Don't you just LOVE physics!?

For a. the hang time is the time the ball was in the air. Some of that stuff we talked about above is pertinent to solving this problem. We know that the velocity of the ball is 0 at its max height, and we also know that if we find the time it takes to reach its max height, we can double that number to find how long it was in the air for the whole trip. Use the one-dimensional equation

[tex]v=v_0+at[/tex] to find out how long it took to reach the max height. Even though we don't yet know the max height, we DO know that the velocity at that point is 0. BUT before we do that, since we are working in the y-dimension only, it would behoove us (benefit us) to find the velocity particular to this dimension. We are going to answer c. first, then backtrack.

c. wants the initial vertical velocity. That is found in the magnitude of the "blanket" or generic velocity times the sin of the angle, namely:

[tex]V_y=25sin(45)[/tex] so

[tex]V_y=[/tex] 18 m/s Now we can use that as the initial upwards velocity in part a:

[tex]v=v_0+at[/tex] and filling in:

0 = 18 + (-9.8)t and

-18 = -9.8t so

t = 1.8 seconds. But remember, this is only half the time it was in the air. The whole trip, then, takes 2(1.8) which is

t = 3.6 seconds

That's a and c. Now for b:

b. asks for the x component of the velocity:

[tex]V_x=Vcos\theta[/tex] which works out to be the same as the vertical velocity, since the sin and cos of 45 degrees is the same:

[tex]V_x=25cos45[/tex] and

[tex]V_x=[/tex] 18 m/s

Onto d:

d. wants the max height. Remember, it took 1.8 seconds to get to the max height, so using yet another one-dimensional equation:

Δx = v₀t + [tex]\frac{1}{2}at^2[/tex] where Δx is the displacement, v₀ is the initial upwards velocity, a is the pull of gravity, and t is the time it takes to reach that max height (Δx, our unknown). Filling in:

Δx = [tex]18(1.8)+\frac{1}{2}(-9.8)(1.8)^2[/tex] and if you do the rounding correctly, you'll end up with this:

Δx = 32 - 16 so

the max height, Δx, is 16 meters.

e. wants the range. That translates to the distance the ball traveled. This is found in a glorified version of d = rt, where d is displacement, r is velocity, and t is...well, time (that doesn't change):

Δx = vt so

Δx = 18(3.6) remember that the ball was in the air for a total of 3.6 seconds, so

Δx = 65 meters.

Phew!!!!! That's a lot! I suggest you learn your physics or this will make you insane by the end of the course!

Explanation:

Pi = Pf + Kf

200 = 50 + Kf

---> Kf = 150J

The kinetic energy of the swing at its lowest point is 150 J.

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.

Given in the question the potential energy of a swing is 200 J at its highest point and 50 J at its lowest point

Pi = Pf + K E

200 = 50 + K E

K E = 150 J

The kinetic energy of the swing at its lowest point is 150 J.

Answer:

A psychoanalyst would see the 4-year-old as having an unresolved conflict where the brain judges or evaluates how good or bad the darkness is, or the usefulness of sleeping in the dark at night based on a comparison, due to the child's exploration of the world around him. A psychoanalyst might see the child's refusal to sleep at night due to the dark as a fear created for instance when the child sleeps alone without the parent. This might change if the child sleeps at night beside the parent in the dark.

While behaviorists would look at how having previous negative experiences in the dark influences a child's behavior towards staying in the dark. This fear would be reinforced with more negative experiences in the dark such as having a bad nightmare whenever the child sleeps in the dark, a feeling of hearing, or seeing strange things while in the dark. These examples would have built a behavioral pattern where the child would be conditioned to respond fearfully to being in the dark.

Answer:

Explanation:

Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times.When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this "photoelectric" effect by proposing that light – thought to only be a wave – is also a stream of particles

Why is light considered a wave and a particle?

Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but not their speed

Paso 2: Calcular la aceleración (a) del cochecito

Usaremos la segunda ley del movimiento de Newton.

F = m × a

a = F/m = 8 N / 0.650 kg = 12.3 m/s²

Paso 3: Calcular el espacio recorrido (x) en 5 segundos (t).

Usaremos la siguiente fórmula cinemática para un movimiento rectilineo uniformemente acelerado.

x = 1/2 × a × t²

x = 1/2 × 12.3 m/s² × (5s)² = 153.75 m

Paso 4: Calcular la velocidad (v) a los 3 segundos si parte del reposo

Usaremos la siguiente fórmula cinemática para un movimiento rectilineo uniformemente acelerado.

v = a × t

v = 12.3 m/s² × 3 s = 36.9 m/s

Los cálculos dados serían los siguientes:

a). Aceleración = 12,3 m / s ^ 2

B). Distancia recorrida en 5 segundos = 153,75 m

C). Velocidad en 3 segundos = 36,9 m / s

Dado que,

Fuerza aplicada = 8N

Peso de la silla de paseo en gramos = 650g

a). To find the aceleración,

[tex]= 12.3 m/s^2[/tex]

Now,

b). :-espacio recorrido en 5 segundos y

Using the Kinematic formula:

[tex]x = 1/2[/tex] × [tex]a[/tex] × [tex]t^2[/tex]

[tex]x = 1/2[/tex] × [tex]12.3 m/s^2[/tex] × [tex](5s)^2[/tex]

= 153.75 m

c). Using the same formula,

velocidad a los 3 segundos si parte
