Answer:
The net force on the car is 2560 N.
Explanation:
According to work energy theorem, the amount of work done is equal to the change of kinetic energy by an object. If '' be the work done on an object to change its kinetic energy from an initial value '' to the final value '', then mathematically,
where '' is the mass of the object and '' and '' be the initial and final velocity of the object respectively. If '' be the net force applied on the car, as per given problem, and '' is the displacement occurs then we can write,
Given, .
Equating equations (I) and (II),
Because it can pollute the air and cause wild life to eat stuff that has been contimanted by the air
Answer:
Explanation:
For light passing through a single slit, the position of the nth-minimum from the central bright fringe in the diffraction pattern is given by
where
is the wavelength
D is the distance of the screen from the slit
d is the width of the slit
In this problem, we have
is the wavelength of the red light
D = 14 m is the distance of the screen from the doorway
d = 1.0 m is the width of the doorway
Substituting n=1 into the equation, we find the distance between the central bright fringe and the first-order dark fringe (the first minimum):
The part of the question that says " x 10⁶ " means
" move the decimal point 6 places that way ===> ".
So take the 1.986 and do that to it.
If there aren't enough places to move the decimal point far enough,
add some zeros to the 1.986 before you move the point.
Explanation:
This should be right. if any doubt post a comment.
