Ultraviolet light with a wavelength shorter than visible light and a higher radiant energy than visible light.
The shorter the wavelength, the higher the frequency and energy.
Answer:
different number of mass numbers.
Explanation:
isotopes are atoms of the same element having the same atomic number but different mass numbers due to different number of neutrons.
Answer:
Explanation:
an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Answer:
0.0000167283525619 N
Explanation:
= Density of silk = 1300 kg/m³
d = Diameter = 0.002 mm
r = Radius = 0.001 mm
l = Length = 16 cm
f = Frequency = 200 Hz
Mass of the string is
Frequency is given by
The tension on the string is 0.0000167283525619 N
Answer:0.45ohms
Explanation:
Let R be there equivalent resistance
1/R=1/r+1/r+1/r
1/R=1/5+1/1+1/1
1/R=1/5+2
1/R=(1+10)/5
1/R=11/5
Cross multiplying we get
11R=5
Divide both sides by 11
11R ➗ 11=5 ➗ 11
R=0.45ohms
