The particle motion increases, and temperature increases. Hope this helps GIVE ME BRANLIST
Stars don't have moons and planets do
Answer:
a.3.84m
b.-106.67m/s
c.947.3m/s^2
d.70.17 rad
e.2.5Hz
d.0.4secs
Explanation:
Given x=(7.8)cos[5πrad/s)t+π/3)]
a.Displacement at t=4.4
7.8cos(5π*4.4+π\3)=3.84m
b.velocity
V= dx/dr=-5π(7.8)sin(5πrad/s)t+π\3
at t=4.4
-5π(7.8)sin(5π*4.4+π\3)=-106.67m/s
c.acceleration
a=d^2x/dr^2
-(5π)^2(7.8) cos (5π*t+π\3)
at t=4.4
-(5π)^2(7.8)cos(5π*4.4+π\3)=-947.3m/s^2
d. Phase =(5πrad/s)t+π\3
At t=4.4
5π×4.4+π\3=70.17 rad
e.frequency
Given x= 7.8cos(5πt+π\3
Compare with x=Acos(2πft)
2πft=5πt
F=2.5Hz
f.T=1\f
T=1/2.5=0.4sec
Answer:
Done
Explanation:
The differences are significant. The main disadvantages of a pinhole camera compared to a modern camera are:
Proper exposure requires a trial and error approach.
Requires manual control of shutter speed (difficult to control)
Poor image quality (due to diffraction effects).
Long exposures (lead to blurry images if the subject moves).
Fixed aperture or f-stop.
Advantages include:
Large depth of field.
Inexpensive
Robust and nearly 100% reliable.
If used properly can create artistic effects.
Light takes 162.1 seconds to travel from Venus to earth.
Explanation:
Speed of light=3 x 10⁸ m/s
distance between Venus and earth =30,220,000 miles=48634375680 m
Now the distance is given by d= v t
d= distance
v= velocity
t= time
48634375680= 3 x 10⁸ t
t=162.1 s
