Answer:
We obtain the average velocity instead of the instantaneus velocity.
Explanation:
The problem with calculating speed in this way is that an average speed is being calculated and not an instantaneous speed at a given point.
To calculate the instantaneous speed, a very small space interval must be measured at a given time.
Answer : The weight of the car is 9800 N
Explanation :
It is given that,
The mass of the car, m = 1000 kg
We have to find the weight of the car. The weight of an object is defined as the force acting on it under the action of gravity. The mass of an object is the amount of matter present in it.
Using second law of motion :
W = m g
Where
m is the mass of the car
g is the acceleration due to gravity g = 9.8 N/kg
W = 1000 kg × 9.8 N/kg
W = 9800 N
So, the weight of the car is 9800 N.
Hence, this is the required solution.
The condition for maximum intensity is the same as that for a double slit. However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating. For a diffraction grating with lines/mm = lines/inch, the slit separation is d = micrometers = x10^ m.
Answer:
if it is a thiner one, yes it will fit because they can expand a pretty far distance
Explanation:
To make it easier to share data and experimental results with other scientists from all over the world.
