An object has a moving energy of 25 J. If I do 25 J of work on the object, how much energy does it have now?

Given data

*An object has moving energy is U = 25 J

*The work done on the object is W = 25 J

As the work is done on the object to increase its velocity, then the energy it has is given as

E_n=U+W

Substitute the known values in the above expression as

\begin{gathered} E_n=(25)+(25) \\ =50\text{ J} \end{gathered}

a ray of light incident on a mirror, at an angle of 45°. Another mirror is placed at an angle of 45° to the first ones as shown.
Gwar [14]

Answer:

If the ray of light is deflected by 45 degrees by the first mirror its total deflection by mirror (I) is 90 deg. (incident = 45 and exit ray equals 45 deg)

The second mirror will cause a net deflection of 90 degrees and the total deflection will be 180 deg or in opposite  direction to the  incident ray.

Scientists often use models to study the movement of continents. Why might scientists use a model to show this movement? A. Extr
egoroff_w [7]

Answer:

Paleontologists have argued for a long time that the demise of the dinosaurs was caused by climatic alterations associated with slow changes in the positions of continents and seas resulting from plate tectonics. Off and on throughout the Cretaceous (the last period of the Mesozoic era, during which dinosaurs flourished), large shallow seas covered extensive areas of the continents. Data from diverse sources, including geochemical evidence preserved in seafloor sediments, indicate that the Late Cretaceous climate was milder than today's. The days were not too hot, nor the nights too cold. The summers were not too warm, nor the winters too frigid. The shallow seas on the continents probably buffered the temperature of the nearby air, keeping it relatively constant.
