A learner's license, like the name suggest (learner), you are just beginning to drive and are "learning" the basics of the car.
For a operator's license, you can drive on your own, you have the knowledge and skills and have taken the required courses and passed them.
Answer:
Explanation:
Initial velocity, u = 85 m/s
Final velocity, v = 45 m/s
Time, t = 4.5 s
We need to find the acceleration of the dragster. The rate at which the velocity of an object changes is called the acceleration of an object. It can be given by :
So, the acceleration of the dragster is and it is deaccelerating.
Answer:
It is the angle of refraction in glass for which the angle of incidence in air is 90°.
Explanation:
When light is refracted, the sine of the angle changes in proportion to the refractive index. When the light is 90 degrees, the sine is zero, and zero is still zero on the other side. So nothing changes.
Explanation:
Given that,
The disintegration constant of the nuclide,
(a) The half life of this nuclide is given by :
(b) The decay equation of any radioactive nuclide is given by :
Number of remaining sample in 4.44 half lives is :
So,
(c) Number of remaining sample in 14.6 days is :
So,
Hence, this is the required solution.
Answer:
245.25 Newtons
Explanation:
the gravitational force of the earth is 9.81 N/Kg
And so to work this out you would multiply 25 by 9.81 to give you 245.25
