The acceleration of a train moving from rest and its speed reaches 36m/sec in 9 sec​

Physics
1 answer:
jenyasd209 [6]2 years ago
4 0

Answer:

4 m/s^2

Explanation:

The acceleration is defined as: Δv/Δt (the difference of the velocity over a time period in which happens that difference).

Remember that a difference is calculated by subtracting the initial value of a physical quantity from its final value.

In our case:

Δv = Vfinal - Vinitial = 36m/s - 0 m/s = 36m/s

Δt = 9s

a = Δv/Δt = 36m/s / 9s = 4m/s^2

Why are not all microorganism harmful?
son4ous [18]


In nature there are two categories of microorganisms as relating to health. Microorganisms that are considered harmful to humans are called pathogens and these cause disease. Examples include bacteria such as streptococcus which cause sore throat and salmonella which cause typhoid disease.

 There are some microorganisms which are helpful to man and they live mostly on the skin of man or in his gut and are mostly bacteria. They are collectively called bacterial normal flora.

In man the normal bacterial flora of the skin include staphylococcus found on dry skin, cornybacteria found in moist skin sites and propionibacteria in the sebaceous sites (head, neck, trunk) of the body. Normal bacterial flora of the gut include Escherichia coli.

One of the major function of bacterial flora is actually to protect our bodies  by competing for space with pathogens preventing them from gaining a foothold in our bodies.

How much heat does it take to raise the temperature of 7.0 kg of water from
aksik [14]

Answer:

non of the above

Explanation:

Quantity of heat = mass× specific heat× change in temperature

m= 7kg c= 4.18 temp= 46-25=21°

.......H= 7×4.18×21= 614.46kJ

Astronaut Rob leaves Earth in a spaceship at a speed of 0.960crelative to an observer onEarth. Rob's destination is a star syste
Slav-nsk [51]

To solve this problem we will use the mathematical definition of the light years in metric terms, from there, through the kinematic equations of motion we will find the distance traveled as a function of the speed in proportion to the elapsed time. Therefore we have to

1Ly =9.4605284*10^{15}m \rightarrow 'Ly'means  Light Year

Then

14.4Ly = 1.36231609*10^{17} m

If we have that

v= \frac{x}{t} \rightarrow t = \frac{x}{t}

Where,

v = Velocity

x = Displacement

t = Time

We have that

t = \frac{1.36231609*10^{17}}{0.96c} \rightarrow c= Speed of light

t = \frac{1.36231609*10^{17}}{0.96(3*10^8)}

t= 454105363 s (\frac{1hour}{3600s})

t= 126140 hours(\frac{1day}{24hours})

t= 5255.85 days(\frac{1 year}{365days})

t = 14.399 years

Therefore will take 14.399 years
