I think it would be helpful to measure gravity so we know how it affects animals and plants and planes and spaceships and cars. I think the most important type of information it gives us is just like making sure people are safe and that there’s nothing we are going on or that the gravity increases at a rate or if it decreases just so we know how to handle it in the future and I think that information would be useful so we don’t die.
It will take them nine seconds to move 36 meters
Answer:
The distance between the 1st order blue fringe and the 1st order red fringe is 6.5 cm.
Explanation:
Given that,
Diffraction grating =1300 lines/cm
Distance of screen = 2 m
Order number = 1
We need to calculate the distance between the 1st order blue fringe and the 1st order red fringe
Using formula of distance
For first order red fringe
For first order blue fringe
We need to calculate the distance between blue fringe and red fringe
Hence, The distance between the 1st order blue fringe and the 1st order red fringe is 6.5 cm.
Answer:
The metric system was originally devised so that water would have a density of 1 g/cm3, equivalent to 103 kg/m3.
Answer:
<h2>4.5 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 0.75 × 6 = 4.5
We have the final answer as
<h3>4.5 N</h3>
