How does displacement, acceleration, time, and velocity affect motion?
Softa [21]

Answer:

The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

Suppose our Sun is about to explode. In an effort to escape, we depart in a spacecraft at v=0.800 c and head toward the star Tau
Levart [38]

Considering a scenario in which the Sun is going to explode.

In order to escape the explosion, we depart in a spacecraft with a speed of v = 0.8c.

The star Tau Ceti is 12 life years away.

At the midpoint of the journey, the Sun as well as Tau Cetik explode. at the same instant.

Imagine a hermit who is immobile with respect to both the Sun and Tau Ceti and resides on an asteroid that is midway between both. He observes the blast waves of both explosions as our spaceship passes him. This observer concludes that the two stars blew up simultaneously because he believes both stars to remain stationary.

In the frame of reference, the Sun and Tau Ceti explode at the same time and will remain stationary.

Jason uses a lens with focal length of 10.0 cm as a magnifier by holding it right up to his eye. he is observing an object that
Svetlanka [38]

Answer:

3.5

Explanation:

The angular magnification, M = 1 + 25cm/f  where f = focal length = 10.0 cm

M = 1 + 25cm/f

= 1 + 25cm/10.0 cm

= 1 + 2.5

= 3.5

The energy of the electron in a hydrogen atom can be calculated from the Bohr formula: In this equation stands for the Rydberg e
labwork [276]

Answer:

Wavelength,\lambda=657\ nm

Explanation:

The energy of the electron in a hydrogen atom can be calculated from the Bohr formula as :

E=\dfrac{-R}{n^2}.............(1)

Where

R is the Rydberg constant

n is the number of orbit

We need to find the wavelength of the line in the absorption line spectrum of hydrogen caused by the transition of the electron from an orbital with to an orbital with n₁ = 2 to an orbital with n₂ = 3.

Equation (1) can be re framed as :

\dfrac{1}{\lambda}=R(\dfrac{1}{n_1^2}-\dfrac{1}{n_2^2})

\dfrac{1}{\lambda}=1.096\times 10^7\times (\dfrac{1}{2^2}-\dfrac{1}{3^2})

\lambda=6.569\times 10^{-7}\ m

or

\lambda=657\ nm

So, the the wavelength of the line in the absorption line spectrum is 657 nm. Hence, this is the required solution.
