The answer is c) electromagnetic sawed in which the vibrations are perpendicular to the motion of the sound
.Answer;
Using Fmax=qVB
F=(1.6*10^-19 C)(5.860*10^6 m/s)(1.38 T)
ANS=1.29*10^-12 N
2. Using Amax=Fmax/ m
Amax =(1.29*10^-12 N) / (1.67*10^-27 kg)
ANS=1.93*10^15 m/s^2*
3. No, the acceleration wouldn't be the same. Since The magnitude of the electron is equal to that of the proton, but the direction would be in the opposite direction and also Since an electron has a smaller mass than a proton
Friction-reducing technologies used in the Variable Compression Turbo Engine are Diamond-like coating on valve lifters, micro finishing on crankshaft and camshaft and mirror bore coating on cylinder wall.
<u>Explanation:</u>
Variable compression is a technology to adjust the compression of an internal combustion engine while the engine is in operation. At this time friction may occur that need to be reduced. To reduce this friction some technologies are used like
- Diamond-like coating on valve lifters
- Micro finishing on crankshaft and camshaft
- Mirror bore coating on cylinder wall
A hydrogen free diamond like carbon coating is applied to an engine valve lifter to reduce mechanical loss. Micro finishing on crankshaft and camshaft achieves improvement in geometric parameters such as roundness. Mirror bore coating on cylinder wall raises energy efficiency by reducing the friction inside the engine.
Solution:
In this question we have given,
initial velocity,u = 0
final velocity, v = 1m/s
displacement =.5mm (Because 1mm=.001m)
We have to find
1.acceleration
2. Time
1. we know third equation of motion is given as,
............(1)
Put values of v,u and s in equation (1)
![[tex]s=1^{2} = 0^{2} +2X.0005Xa\\1= .001a\\therefore, a = 1/.001\\ a= 1000m/s^{2}](https://tex.z-dn.net/?f=%5Btex%5Ds%3D1%5E%7B2%7D%20%3D%200%5E%7B2%7D%20%2B2X.0005Xa%5C%5C1%3D%20.001a%5C%5Ctherefore%2C%20a%20%3D%201%2F.001%5C%5C%20a%3D%201000m%2Fs%5E%7B2%7D)
2. We know First equation of motion is given as
......................(2)
put values of v, u and a in equation(2)
A ship sailing away from you gradually goes out of sight,
starting from the bottom and moving up the sides of the ship.
The Earth is a sphere. As the ship gets farther away from
you, it's working its way around the curve of the sphere.
Since you can't see around the curve of the Earth, the
lowest point on the ship that you can see moves slowly
up the ship.
