Answer:

x = 0.78 m = 78 cm

Explanation:

Applying the law of conservation of energy to the spring-mass system, we can write the following equation:

[tex]Kinetic\ Energy\ at\ Mean\ Position= Potential\ Energy\ at\ extreme\ position\\\frac{1}{2}mv^2 = \frac{1}{2}kx^2\\\\x^2 = \frac{mv^2}{k}\\\\x = \sqrt{\frac{mv^2}{k} }[/tex]

where,

x = maximum displacement = ?

m = mass = 3.6 kg

v = speed at mean position = 5.2 m/s

k = spring constant = 160 N/m

Therefore,

[tex]x = \sqrt{\frac{(3.6\ kg)(5.2\ m/s)^2}{160\ N/m} }\\\\[/tex]

x = 0.78 m = 78 cm

Hope it help you

Answer:

F = 0.0112 N

Explanation:

Given that,

Masses, [tex]m_1=m_2=6500\ kg[/tex]

The distance between masses, d = 0.5 m

We need to find the gravitational force between two large trucks. The formula for the gravitational forces is given by :

[tex]F=G\dfrac{m^2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{6500^2}{(0.5)^2}\\\\F=0.0112\ N[/tex]

So, the required force between masses is equal to 0.0112 N.

Answer:

C

Explanation:

So, lets start off by thinking about what we know is in both cells, and rule out from there.

There are just some basic things you need in eukaryotic cells, those include the following:

Here are jsut a few examples of what can be found in both plant and animal cells, however we can already rule out all of the following except for:

C

Because remember, c talks about the chlorplast, which is not the chlorplasm found in both plant anf animal cells, its just the chloroplast found in plant cells.

Although I gave the asnwer to you. Here are some things that are in plant cells that arent in animal cells:

Animal cells on the other hand, have a few things that plant cells do not as well:

Answer:

The potential energy of the ball becomes 0

Explanation:

When kicking the ball, and it moves up, the potential energy of the ball increases. When the ball descends downwards, the potential energy of the ball reduces.

This is so because potential energy increases as height increases and decreases when there is a reduction in height.

So, when you stop kicking the ball and you place the ball on the floor, the ball becomes static (motionless); hence, the potential energy becomes 0.

Answer:

Q=mc(T2-T1)

Explanation:

Ti is the temperature

m is mass

c is specific heat capacity for steam

Q is heat, [Q]=J

Answer:

A

Explanation:

Answer:

Given that - R = 6 ohm

V = 3 volt

n = ?

so by ohms law , V = I X R

I = V \ R = 3 \ 6 = 0.5 A

we know that I = Q / T here t is 1 sec

Q = I X T = 0.5 X 1 = 0.5 C

By the law of quantization ,

Q = n x e

n = Q / e = 0.5 / 1.6 x 10 ^-19

n = 0.3125 x 10^19

Answer: 0.7

Explanation:

A fisherman sees 7 wave crests go by in 10 s, with wavelength (λ) ia 2.43 m has the frequency of the wave is 0.7 hertz.

A wave is defined as the propagation of distrubance from one place to another. It can carries energy when it propagates into the medium without the net movement of the particles.

It refers to the variations or flow of energy without the transfer of mass of particles or matter. The waves can be visible or invisible. Light and sound are travel in the form of waves.

In waves, the wavelength, frequency, wavespeed and time period can be identified. Frequency refers to the number of oscillations takes place per unit time. It is measured in hertz (Hz).

Wavelength(λ) defines the distance travelled by the wave in a particular time in one vibration. It is also defined as the spatial period of the wave. It can be obtained by taking ratio between wavespeed and frequency. The unit of wavelenght is meter(m).

Wavespeed of the wave equals the wavelength and frequency. It defines the distance travelled/ number of meter covered by given time. Wavespeed (v) = wavelength (λ) / frequency (f). Its unit is m/s.

Time period is inversely proportional to the frequency (f). The time taken by the wave to complete its one oscillation is called time period. Time period = 1 / f . Its unit is seconds (s).

From the given,

time = 10 secs

no of waves = 7

wavelength = 2.43 m

To obtain frequency from the givens, the formula for frequency is:

frequency = no.of.cycles of waves / time taken

                 = 7 / 10

          f     = 0.7 hertz.

Hence, the frequency of the wave is 0.7 Hz for 7 waves and given time 10 s.

In my opinion, mental health can affect all of these options. However, I think the answer this is looking for would be "A person's ability to breathe"

Mental health definitely affects motivation; and motivation affects mental health. Motivation is a driving force behind human behaviours; its absence can lead to mental illnesses such as depression. Often when someone is depressed, they lack the motivation to do things.

Mental health can affect decision making as well- for example, if someone has anxiety, decision-making can be harder. Anxiety disrupts the decision-making regions in the prefrontal cortex.

Mental health can also affect memory- Depression has been linked to memory problems, such as forgetfulness. Depression is associated with short-term memory loss. Stress and anxiety can also lead to poor memory.

I would say that panic attacks can inhibit a person from breathing, but considering the options I would say that's the best one. Breathing is more of a physical thing, not associated with the brain or mental condition. So the answer is A person's ability to breathe.

Answer:

Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant. Fluid friction can be minimized by giving suitable shapes to the objects moving in the fluids.

Explanation:

The interference is a  type of wave interaction shown in the photo. Option A is correct.

The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.

The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.

When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.

The interference is a  type of wave interaction shown in the photo

Hence option A is correct.

Answer:

Lo primero que hay que recordar es la relación:

Velocidad = Distancia/tiempo.

Para el caso de Pedro, el vive a 5km de la escuela (es decir, para llegar a la escuela, el debe recorrer -5km, entonces la distancia es -5km), y recorre esa distancia en 0.25 horas, entonces su velocidad es:

Velocidad = -5km/0.25hr = -20km/h

Esto significa que Pedro se mueve con una velocidad de -20km/h, lo que significa que se mueve hacia el oeste con un módulo de 20km/h

Para el caso de Juan, el vive a -4km de la escuela, entonces el tendrá que recorrer 4km para llegar a la escuela, y los recorre en 0.25 horas, entonces su velocidad sera:

Velocidad = 4km/0.25h = 16 km/h

Lo que significa que Juan tiene una velocidad de 16km/h hacia el este.
