Newton's 2nd law of motion: Force = (mass) x (acceleration)

You need to find the acceleration, so divide each side by (mass):

Acceleration = (Force) / (mass)

Plug in the numbers you know from the question:

Acceleration = (300,000 Newtons) / (20,000 kilograms)

<em>Acceleration = 15 m/s²</em>

This is a huge acceleration. It's 53% faster than a falling rock (gravity).

The boiling point of sulfur is 444.6 celsius .sulfur melting point is 586.1 fahrenheit lower than its boiling?

iVinArrow [24]

Answer:

(a) Melting point is 136.8°C

(b) Melting point is 278.24°F

Boiling point is 832.28°F

Boiling point is 717.6K

Explanation:

(a) 586.1°F = 5/9(586.1 - 32)°C = 307.8°C

Melting point = 444.6°C - 307.8°C = 136.8°C

(b) Melting point = 136.8°C = (9/5×136.8) + 32 = 278.24°F

Boiling point = 444.6°C = (9/5×444.6) + 32 = 832.28°F

Boiling point = 444.6°C = 444.6 + 273 = 717.6K

लाइ फ्युजका<br>4<br>Why MCB is called the developed form of fuse? Give the reason

DerKrebs [107]

Miniature circuit breakers is called the developed form of fuse because MCBs are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings

If 730-nm and 640-nm light passes through two slits 0.61 mm apart, how far apart are the second-order fringes for these two wave

Naddik [55]

Answer:

X2 - X2'=3.24×10⁻⁴m

Explanation:

Given Data

λ1=730nm=

λ2=640nm

d=0.61 mm

D=1.1 m

Distance of the second bright fringe from the central fringe is given by

Xn = = D x n x2 λ / d

X2 = 2 D λ1 / d

X2' = 2 D λ2 / d

Separation between the second bright fringes of the two wavelengths ( the separation between the second order fringes ) is ,

X2 - X2' = 2 D ( λ1 - λ2 ) / d

X2 - X2'= {2 x 1. 1 (730×10^-9 - 640×10^-9) }/ 0.61 x 10 ^-3

X2 - X2'=3.24×10⁻⁴m

An object travels along a straight line across a horizontal surface, and its motion is described by the velocity versus time gra

Mkey [24]

Answer:

C.)Finding the area bound by the horizontal axis and the curve from 0 s to 5 s

D.)Using Average Speed = total distance/total and multiplying the average speed of 5m/s by a total time of 5 s

Explanation:

The graph seems to be missing, however we can still answer the question.

In fact, we have to keep in mind the following facts:

- In a velocity-time graph, the area under the curve represents the displacement of the object, while the slope of the curve corresponds to its acceleration.

From this, we can already say that the following option:

C.)Finding the area bound by the horizontal axis and the curve from 0 s to 5 s

is correct, while the statement

A.)Finding the slope of the line between 0 s to 5 s

is wrong.

Moreover, the average speed of an object in motion is given by

$v=\frac{d}{t}$

where d is the total distance covered while t is the total time taken. Once we have calculated the average speed, the total displacement over a certain time period can be simply calculated by multiplying the average speed by the time interval: so, the option

D.)Using Average Speed = total distance/total and multiplying the average speed of 5m/s by a total time of 5 s

is also correct.

The last option remained:

B.)Dividing the change in velocity between 0 s to 5 s by the change in time

is wrong, because in this way we are calculating the acceleration, not the displacement.
