A 1000-kg car moving at 10 m/s brakes to a stop in 5 s. the average braking force is

Physics

Marina86 [1]3 years ago
4 0
To calcculate the braking force of the car moving, we use Newton's second law of motion which relates the acceleration and the force of an object moving. The force of an object moving is directly proportional to its acceleration and the proportionality constant is the mass of the object. It is expressed as:

Force = ma

Acceleration is the rate of change of the velocity of a moving object. We calculate acceleration from the velocity and the time given above.

a = (10 m/s) / 5 s = 2 m/s^2

So,
Force = ma
Force = 1000 kg ( 2 m/s^2 )
Force = 2000 kg m/s^2 or 2000 N

Cytosine is methylated resulting in 5-methylcytosine. What is the most likely outcome?.
Allisa [31]

Answer: Cytosine is methylated resulting in 5-methylcytosine. Then the gene expression will decrease.

Explanation: To find the answer, we need to know more about the methylation of cytosine.

<h3>What is methylation of cytosine?</h3>
  • Methylation means the addition of a methyl group on a substrate of an atom.
  • It's a form of alkylation, here a methyl group replaces a hydrogen atom.
  • Methylation of cytosine occurs at CpG palindrome in DNA.
  • When cytosine is methylated to produce 5- methyl cytosine, which results in a decrease in gene expression.

Thus, we can conclude that, Cytosine is methylated resulting in 5-methylcytosine. Then the gene expression will decrease.

А masd<br>Of 500kg a raised to a height of 6m In 30s<br>Find (a) Workdone .​
Mazyrski [523]

Answer:

Work done is 882000joule.

power is 29400watt.

Explanation:

given,

Mass(m)=500kg

Acceleration due to gravity(g)=9.8m/s²

Height(h)=6m

Time taken(t)=30s

Workdone=?

Power=?

now,

workdone=force*displaxement

= m*g*h

=500*9.8*6

=8,82,000joule

so, the work done by the man is 8,82,000joule.

then,

power=workdone/time taken

=8,82,000/30

=29,400watt

so, the required power to lift a load is 29,400watt.

In a 2-dimensional coordinate system, which of these is an example of an object's position?
Serjik [45]

' B ' is the only choice on the list that tells you a definite place, where you could go to pick up the object or meet somebody.

But in order to use it, you also have to know where the origin of coordinates is ... the point (0, 0) .

__________

No, I'm wrong about that.  You have to know where SOME other point is, but that doesn't have to be (0, 0).

Describe one behavior that shows that light is a wave
Brilliant_brown [7]
All waves are known to undergo reflection or the bouncing off of an obstacle. Most people are very accustomed to the fact that light waves also undergo reflection. The reflection of light waves off of a mirrored surface results in the formation of an image.

High rate of evaporation in a water cycle can most likely cause
scoray [572]
Answer: d. thunderstorms
The option <span>blizzards can be excluded as it is clearly not related to the evaporation. Floods can happen if the condensation rate high, not evaporation. Sometimes the cloud that carries water is just blown up by the wind so the evaporation does not happen in that place.
Thunderstorms happen more in summer because the rate of evaporation and condensation is increased.</span>
