Answer:

C. All energy in the universe is a result of mass being converted into energy.

Explanation:

Answer:

C

Explanation:

edgeee

Answer:

q = 0.036 C

Explanation:

Given that,

Current passes through a defibrillator, I = 18 A

Time, t = 2 ms

We need to find the charge moved during this time. We know that,

Electric current = charge/time

[tex]q=It[/tex]

Put all the values,

[tex]q=18\times 0.002\\\\q=0.036\ C[/tex]

So, 0.036 C of charge moves during this time.

Answer:

Distance is directly proportional to the velocity

Explanation:

In 1929, Edwin Hubble's wrote an article that talked about relationship between the distance and recession speed/velocity of galaxies which led to what is known as the Hubble Law. This law states that galaxies are moving away from the earth at velocities proportional to their distances.

Thus is written as;

v = H_o•d

Where;

v is velocity

d is distance

H_o is Hubble's constant rate of cosmic expansion.

He came to this conclusion by generating a graph known as Hubble's classic graph which was a graph of observed velocity vs distance for nearby galaxies.

What is Azimuth ?

answer : angle of a sound source on the horizontal plane relative to a point in the center of the head between the ears ( D )

Explanation:

Azimuth is the described as angle of a sound source ( between the North ) and it is measured in a clockwise direction in relation to the observer ( Human ear )

Hence the option that fits in is : angle of a sound source on the horizontal plane relative to a point in the center of the head between the ears

Answer:

Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn. When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.

please mark as brainliest

Answer: The area of the edge of a knife’s blade is very small

Syringes are used to take blood for blood tests.

When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.

Skis have a large area to reduce the pressure on the snow.

Answer:

Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion

Explanation:

A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object

When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or   continue its uniform motion on a straight path unless a force acts on the object

The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest

Therefore;

From a FBD it is possible to tell if an object is moving or not.

Answer:

it is going 1.894miles in 25 hours so it travels 0.07576 miles per hour

Answer:

From big bang and stars.

Explanation:

The extra helium got into the universe through big bang and fusion reaction that occur in stars. Our universe formed about 13.7 billion years ago with big explosion, this event is known as big bang. The fusion of hydrogen nuclei in the stars produces helium and energy so we can say that most of the extra helium got into the universe through fusion reaction that occur in the stars continuously.

Answer:

B: 28m/s

Explanation:

Use the speed formula

Speed =distance / time

Answer:

[tex]\boxed {\boxed {\sf B. \ 28 \ m/s}}[/tex]

Explanation:

If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.

[tex]s=\frac{d}{t}[/tex]

The cheetah ran 112 meters in 4 seconds.

Substitute the values into the formula.

[tex]s=\frac{112 \ m}{ 4\ s}[/tex]

Divide.

[tex]s= 28 \ m/s[/tex]

The cheetah's speed is 28 meters per second and choice B is correct.

Answer:

Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook's hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.

Explanation:

It’s a because a electrolyte reproduces

Answer:

look at the picture i have sent

Answer:

solution given:

frequency[f]=215.0Hz

velocity[V]=x

wave length=2.4m

we have

wave length=[tex] \frac{V}{f} [/tex]

2.4m=[tex] \frac{x}{215} [/tex]

2.4×215=[tex] \frac{x}{} [/tex]

x=516 m/s

velocity=speed =516m/s

Answer:

mass of block=2.7 gm

Explanation:

concept: Density=mass/volume

given:ρ=2700 kg/m^3 and v=250 cm^3 (in cm^3 not in m^3)

=> v= convert cm^3 to m^3

there fore= 1 cm^3=1 cm*1 cm*1 cm

i.e 1 cm^3=1/100*1/00*1/100 m^3 => 1 cm^3=1/1000000 m^3

ρ=m/v

=>mass=ρ*volume

=>mass=2700*1/10^-6

=>mass=2.7*10^-3 kg =>2.7 gm

Answer:

[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]

Explanation:

Given the following data;

Original volume = V

New volume = V'

Original temperature = T

New temperature = T'

To write an expression for Charles's law;

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by the formula;

[tex] \frac {V}{T} = K[/tex]

[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]

Answer:

Definition of a scientific theory.

Answer:

theories on edge

Explanation:

Answer:

[tex]\mu=0.06[/tex]

Explanation:

Given that,

Mass of a block, m = 2 kg

Velocity of the block, v = 6 m/s

It stopped in 10 s

We need to find the coefficient of friction.

The frictional force is balanced by the opposing force such that,

[tex]\mu mg=ma\\\\\mu=\dfrac{a}{g}[/tex]

Where

a is acceleration, a = 6/10 = 0.6 m/s

So,

[tex]\mu=\dfrac{0.6}{10}\\\\\mu=0.06[/tex]

So, the coefficient of friction is equal to 0.06.

Answer:

there it is fella tried on ma own consciousness

Answer:

No, you couldn't function the same as you do now.

Explanation:

This is because each cell follows individual tasks, and makes up specific parts of a body. For example, if all of your cells were those of an eye, you would be missing the components of arms, legs, etc.

Answer: No

Explanation: If all the cells of our body were of the same size, shape and volume, then they would all perform the same function and the multitude of other important functions cannot be carried out, without which human life itself would not be possible.

Answer:

A

Explanation:

Answer:

1. Plateau where the temperature stays constant

2. Melting

3. Boiling points of the substance

Explanation:

The relationship between kinetic energy and temperature is given as follows;

[tex]\overline E = \dfrac{3}{2} \times \dfrac{R}{N_A} \times T[/tex]

Where;

[tex]\overline E[/tex] = The average kinetic energy of the atom

R = The universal gas constant

[tex]N_A[/tex] = Avogadro's number

T = The temperature in Kelvin

Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance

Therefore, we have;

If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. plateau where the temperature stays constant on a heating curve, which occur at the 2. melting and 3. boiling points of the substance.

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass

Answer:

the noun of deposition is the action of deposing someone, especially a monarch.

A "screen" or even just a set of parallel bars are highly reflective to electromagnetic waves as long as the open spaces are small compared to the wavelengths.

"Grid" dishes work fine ... with less weight and less wind resistance ... for frequencies below about 3 GHz. (Wavelengths of at least 10 cm.)

(I even worked on a microwave system in South America where huge grid dishes were used on a 90-mile link.)

Answer:

Equivalent resistance of the circuit is 116 ohm.

Explanation:

Finding the equivalent resistance of the circuit. Since, 29 ohm resistors are connected in series, so

→ Equivalent resistance = R_1 + R_2 + R_3 + R_4

→ Equivalent resistance = (29 + 29 + 29 + 29) ohm
