Physics
1 answer:
Flauer [41]3 years ago
6 0

Answer:

These low-pressure gases prevent the filament inside the bulb from burning out; it also relieves some of the stress on the glass globe from normal atmospheric pressure, lessening the chance of glass breakage.

A 238 N force is applied to a 25 kg object. What is the object's acceleration?
Ganezh [65]

Answer:

<h2>9.52 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{238}{25}  \\  = 9.52

We have the final answer as

<h3>9.52 m/s²</h3>

Hope this helps you

The vacuum tube was replaced with what electrical component?
Rufina [12.5K]

Answer:

The vacuum tube was replaced with transistor.

Explanation:

  • The invention of semiconductor was very useful in making solid state transistor that allowed the production of small yet faster, cheaper, and more trusted and reliable computers.
  • These solid state transistor is so often used that, it nearly replaced all the use of transistor.
  • This replacement took place after the invention of semiconductor in the year around 1940.
  • Vacuum tubes also known as thermionic tubes are not used anymore in computers and electronics.

A planet follows an elliptical orbit that brings it as close as 21 million km to a star and as far as 75 million km from the sta
nexus9112 [7]

Answer:

Explanation:

In an elliptical orbit , the angular momentum of the planet remains constant because velocity of planet makes a right angle to the direction to the star .

mvr = constant .

mv₁r₁ = mv₂r₂

v₁r₁ = v₂r₂

v₁ x 21 = 38 x 75

v₁ = 135.71 km/s .

A blue train of mass 50 kg moves at 4 m/s toward a green train of 30 kg initially at rest. What is the initial momentum of the b
emmainna [20.7K]

<em>The correct option is</em> D.   The initial momentum of the blue and green train combined during the collision is 200 kgm/s.

<h3>Initial momentum of the blue and green train</h3>

Apply the principle of conservation of linear momentum as follows;

Pi = m1v1 + m2v2

where;

  • m1 is mass of blue train
  • m2 is mass of green train
  • v1 is velocity of blue train
  • v2 is velocity green train
  • Pi is the initial momentum of the two trains

Pi = (50 x 4) + 30(0)

Pi = 200 kgm/s

Thus, the initial momentum of the blue and green train combined is 200 kgm/s.
