Answer:

D. 75 watts

Explanation:

brainliest please? i've just answered 3 of your questions and they were all correct! :) i hope i helped!

Answer:

(D) =75 WATTS

Explanation:

p(power)=i(current)×v(voltage)

p = 0.625 × 120

p =75 watts

Explanation:

A withered plant. Unless the plant is one of the many plants that have huge water retention capacity, for example, cactus. Such plants also don't need water to gr6, they just need a tiny amount of water, ba sufficient sunlight to enable them complete photosynthesis.

Any other plants asides one of the many like that, he will definitely come back to a dead, or at best, withered plant. A month is too long a time to not take care of your plant and expect it to still be up and running

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.

Explanation:

mass(m)=2 kg

velocity(v)=5m/s

Now,

Kinetic energy(K.E.)=1/2mvsq

=1/2×2×5sq

=25

where,sq=square(2)

C. Light rays are bent by the water in the glass.

Explanation:

The light defracts as is it leaves the medium of air and enters the medium of the water/glass.

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.

Explanation:

Mitochondria are essential parts of many eukaryotes, but they are useless without oxygen. Therefore, chloroplasts are extremely important. They produce breathable air for life. Root hairs are seen to not have chloroplasts as their job is to collect water and nutrients.

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

Answer:

1) x rays

Explanation:

Honestly Gamma rays has the Highest frequency, but in your options, gamma rays is not among, so x rays has the highest frequency among your options.

Answer:

F = 100 Newtons

Explanation:

F = ma

F = (50 kg)(2 m/s)

F = 100 kg*m/s

Answer:

some symptoms can be lack of energy, and dizziness.

Explanation:

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.

Answer:

q = 1

Explanation:

Given that,

No. of electrons = -12

No. of protons = 13

We need to find the net charge on the balloon. We know that net charge is equal to the sum of proton and the electrons such that,

Net charge = No. of electrons + no. of protons

= -12 + 13

= 1

So, the net charge is equal to 1.

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:

the second picture

Explanation:

Answer: second picture

Explanation:

(it was right on my gizmo sheet)

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

hoped so u got the answer mark me as brainellist :)

Answer:

0.5/1.6×10^-19

Explanation:

formula for current is v

I R

3/6=0.5

charge if found by the product of current and time which is one second

0.5×1 =0.5

deficiency of n=no of charges×charge of electrons

0.5/1.6×10^-19

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.

The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.

How photosynthesis and cellular respiration are similar:

Photosynthesis is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration.

Answer:

300 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

s = 40 × 15 / 2

s = 600 / 2

s = 300 m

Thus, the distance travelled by the motorbike is 300 m.
