When you are talking about calculating the kinetic energy of an object, the formula is as stated:
Ek =1/2mv²
Where m is mass and v is velocity. Sub all those numbers in and you'll get 25J of kinetic energy.
Answer:
There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
Explanation:
Plants and animals need nitrogen in order to make proteins. Proteins are essential compounds for healthy growth and fully functioning organisms.
The correct answer is 10 years
In the double-slit interference experiment, the distance of the nth-maximum from the center of the screen is given by

where

is the wavelength
D is the distance between the screen and the slits
d is the distance between the slits
In our problem,



By applying the previous formula, we can calculate the distance of the 4th maximum from the center of the screen:

Similarly, the distance of the 8th- maximum is

Therefore, the distance between the two maxima is
