If Angela ran to the bus and back to where she started what distance would she travel ?

Answer:

Ideal machines are said to have parts which are weightless , frictionless and strings if any are inextensible. Practical machines have parts which have weights, friction and it causes some loss of work done.

Answer:

1:25

Explanation:

The force acting on an object is given by :

F = ma ...(1)

m is mass and a is acceleration

It is given that the ratio of force acting on the bus and car 25:1 i.e. [tex]\dfrac{F_1}{F_2}=\dfrac{25}{1}[/tex], 1 is for bus and 2 is for car.

We need to find the ratio of the acceleration produced in the car to the acceleration produced in the bus. From equation (1),

[tex]\dfrac{F_1}{F_2}=\dfrac{a_1}{a_2}[/tex]

[tex]\dfrac{a_2}{a_1}=?[/tex]

[tex]\dfrac{F_1}{F_2}=\dfrac{1}{25}[/tex]

So, the ratio is 1:25.

Answer: A Cytosol

Explanation: Jelly - like fluid that fills the space between cell organelles. Hoped This Helped :) Have a blessed day.

The cytoskeleton, which gives a cell its structure, allows organelles to move inside the cell, and provides a method by which the cell itself can move, is an ordered framework of fibrous molecules found in the cytoplasm. Thus, option A is correct.

The fluid that fills cells is called cytosol. In this water-based solution, organelles, proteins, and other cell components float. Any cell's cytosol is a sophisticated solution whose characteristics allow for the performance of life's essential processes.

The cytoplasm houses all the organelles found in eukaryotic cells, including the nucleus, endoplasmic reticulum, and mitochondria.The portion of the cytoplasm that is not contained in an organelle is known as the cytosol.

Therefore, Although the cytoplasm may not seem to have any shape or organization, it is actually quite well-organized.

Answer:

Gamma radiation .

Explanation:

Three types of emission result at the time of nuclear emission .

alpha emission

Beta emission

Gamma radiation emission

Gamma radiation results in the emission of gamma ray . This is a very high frequency radiation . It is not a particle having charge and mass like alpha and beta emission . So it has no effect on the mass and charge of the product that is formed after gamma radiation . The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product . It causes negligible change in the mass of the product and no change in the charge of the product.

That is why , generally this product is not written in the nuclear reaction .

Answer:

The answer is Gamma ray

Explanation:

Because this is a very high frequency radiation, is not a particle having charge and mass like alpha and beta emission, so it has no effect on the mass and charge of the product that is formed after gamma radiation. The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product, it causes negligible change in the mass of the product and no change in the charge of the product.

Answer:

chloroplast

Explanation:

Endosymbiosis theory explains the origin of chloroplast and mitochondria in the eukaryotic organisms.

When the pro-eukaryotes engulfed the blue-green algae or photosynthetic bacteria, these bacteria formed the symbiotic relationship with the pro-eukaryotes. These photosynthetic bacteria transformed into the chloroplast organelles of the eukaryotes which can capture the sunlight and use it in the synthesis of glucose molecules. These eukaryotic cells later formed the plant kingdom.

Explanation:

Friction can't affect mass of a substance(considering for a substance whose mass doesn't change with time),rather it is the mass of an object which can affect friction variously. Let's take some example to understand the situation. So,higher the mass of the object,higher will be the frictional force.

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

Answer:

48.3mph

Explanation:

Given that

Distance = 222.0miles

Time = 4.596hours

Average speed = total distance/total time

= 222.0miles/4.596

= 48.3mph

Hence the average speed is 48.3mph

Answer:

Omnidirectional antennas are inadvisable to be used because when oriented vertically they radiate radio power equally in all horizontal directions, but heir radio power varies with the angle to the axis, reducing to zero at the axis.

Explanation:

Omnidirectional antennas radiates equal radio power in all directions perpendicular to an axis, with power varying with the elevation angle. This means that their power declines to zero on the axis. This is unlike the isotropic antennas that radiates equal power in all directions, without any reduction in radio power with angle to the axis. Omnidirectional antennas are mostly used for radio broadcasting antennas in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks etc.

Explanation:

6.20=6.2kg

Explanation:

initial velocity, u = 75m/s

acceleration, a = -20m/s2

final velocity, v = 0m/s (rest)

Using the formula,

v = u + at

0 = 75 + (-20)t

t = 3.75 seconds

Answer:

6.93 m/s^2

Explanation:

Given that the The net external force on the propeller of a 3.32 kg model airplane is 23 N forward

Where

Mass M = 3.32kg

Force F = 23 N

Force = mass × acceleration

Substitute all the parameters into the formula

23 = 3.32 × a

a = 23/3.32

a = 6.93 m/s^2

Therefore, the acceleration of the airplane is 6.93 m/s^2

Answer:

76.9231

Explanation:

Divide 400m by 5.2 to get the answer.

Speed = (distance) / (time to cover the distance)

Speed = (400 m) / (5.2 minutes)

Speed = (400 m) / (312 seconds)

Speed = 1.28 m/s

There's not enough given information to find his velocity.

(I'll be honest with ya, Flash: 1.28 m/s is no big deal. It's only about 2.87 miles per hour. My dog can walk faster than that, and so can most healthy people. If that's the best you can do, then you probably shouldn't be running around chasing bad guys.)

The average acceleration of the motorcycle is determined as 3 m/s².

The acceleration of the motorcycle is calculated as follows;

a = (v - u)/t

where;

a = (15 - 6)/3

a = 3 m/s²

Thus, the average acceleration of the motorcycle is determined as 3 m/s².
