Answer:
Growth rate in micrometers per second is 3.05.
Given:
Growing length = 3.7 meter
Time = 14 days
To find:
Growth rate = ?
Formula used:
Growth rate =
Solution:
Growth rate =
Growing length = 3.7 × micrometer
Time = 14 × 24 × 60 × 60
Growth rate =
Growth rate = 3.05 micrometer per second
Growth rate in micrometers per second is 3.05.
Answer:
The electrons are moving through the superconductor per second.
Explanation:
Given :
Current A
Charge of electron C
Time sec
From the formula of current,
Current is the number of charges flowing per unit time.
Where number of charges means in our case number of electrons
Therefore, electrons are moving through the superconductor per second.
Answer:
1.Theimage will be located at -0.13m or -13 cm
2.The height of the image will be 0.052m or 5.2cm
Explanation:
Given that;
Height of object, h=20 cm = 0.2m
Object distance in front of convex mirror, o,= 50 cm =0.5m
Radius of curvature, r, =34 cm =0.34m
Let;
Image distance, i,=?
Image height, h'=?
You know that focal length,f, is half the radius of curvature,hence
f=r/2 = 0.34/2 = 0.17m ( this length is inside the mirror, in a virtual side, thus its is negative)
f= -0.17m
Apply the relationship that involves the focal length;
Re-arrange to get i
This is a virtual image formed at a negative distance produced through extension of drawing rays behind the mirror if you use rays to locate the image behind the mirror
Apply the magnification formula
magnification, m=height of image÷height of object
substitute the values to get the height of image h'
Answer:
in a vacuum
Explanation:
Electromagnetic waves are waves consisting of oscillations of electric and magnetic fields along a plane perpendicular to the direction of propagation of the wave (transverse waves)
Electromagnetic waves are the only waves being able to travel in a vacuum, since they do not need a medium to propagate.
In a vacuum, all electromagnetic waves travel at the same speed, called speed of light, whose value is:
The speed of the waves is actually reduced when they enter a medium, according to
where n is the refractive index of the medium.
Electromagnetic waves are also classified into 7 different types according to their wavelength. From shortest to longest wavelength, we have:
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared
Microwaves
Radio waves
