When the air density is 0 kg/m°(vacuum), how long will it take an object to reach terminal velocity?

Physics

1 answer:

Drupady [299]4 years ago

3 0

Answer:

d. The object never reaches terminal velocity.

Explanation:

Terminal velocity is the velocity a falling object reaches when the air resistance equals the weight. But in a vacuum, there is no air resistance. So the object never reaches terminal velocity.

How do I find distance traveled

Marianna [84]

Answer:

To solve for distance use the formula for distance d = st, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t.

The wavelength at which Earth’s emitted radiation is maximum is ______ at which the wavelength of the Sun’s emitted radiation pe

tatiyna

Answer:

inversely proportional to the temperature

Explanation:

Wein's displacement law states the wavelength at which Earth’s emitted radiation is maximum <u>is inversely proportional to the temperature</u> at which the wavelength of the Sun’s emitted radiation peaks.

λmax $= \frac{b}{T}$

where,

λmax is the maximum wavelength

b is a constant of proportionality called Wien's displacement constant (b = 2.897 × 10⁻³ m.K)

T is the absolute temperature in kelvins

When Jacob bats a baseball with a net force of 4.719 N, it accelerates 33 m/s2. What is the mass of the baseball?

andreev551 [17]

Answer:

Mass=0.143 kg

Explanation:

From the Newton's second law of motion the force applied to an object is directly proportional to the acceleration produced and the acceleration is in the direction of the force.

F=ma where F is the force, m is the mass of the object and a i the acceleration.

m=F/a

=4.719N/33 m/s²

=0.143 kg
