Force = mass * acceleration, with units kg*m / second squared, or the more commonly the Newton, N. Assuming objects freely fall due to gravity at 9.8 m/second squared, and zero air resistance force opposing the freely falling object, 1 kg * 9.8 m/second squared = 9.8 N = force on the ball.
Answer:
221754385964.9123
Explanation:
Convert miles to nanometer
1 mile = 1.6 km
1 km = 1×10³×10³×10³×10³ nm
1 mile = 1.6×10¹² nm
So,
158 miles = 158×1.6×10¹² = 252.8×10¹² nm
Length of each molecule = 1140 nm
Number of molecules = Total length / Length of each molecule
There are 221754385964.9123 number of molecules in a stretch of 158 miles
Answer:
force pushed the object = 10 × 5 = 50N
A=ω²r=0.8²*3.2=2.0 m/s²
v=ωr, then ω=v/r;
ω=2.6/3.2=0.8 rad/s
The fringes will be farther apart
The width of the centre maxima on a screen is twice the distance between the dark fringes on either side at a distance L away: The pattern of light spreads out as you get further away from the screen (bigger L). The pattern of light widens as the hole gets smaller (smaller a).
<h3>What is Double slit experiment ?</h3>
The double-slit experiment involves directing a beam of light at a wall that has two vertical slits. The pattern that results from the light passing through the slits is captured on a photographic plate. A single line of light is seen when one slit is covered, aligned with the open slit.
- In essence, waves passing through two closely spaced, parallel slits produce an interference pattern on a screen. Everyone should know this. This is true for all types of waves sound wave, light wave etc
