Answer: SI Unit is meters per second(m/s)
Explanation:
The three units of speed are:
1. meters per second(m/s)
2. kilometers per hour(km/hr)
3. miles per hour(mph)
SI Unit is meters per second(m/s)
Answer:
Explanation:
mass of electron in amu = .000549
mass of electron = mass of proton
total mass of electron and proton = 2 x1.098 x 10⁻³ = 2.196 x 10⁻³ amu
1 amu = 931 x 10⁶ eV
2.196 X 10⁻³ amu = 2.196 x 931 x 10³ eV
= 2.044 X 10⁶ eV.
= 2044 X 10³ ev
So minimum energy required = 2044 x 10³ eV.
Wavelength of photon required = 12375/2044 x 10³ A
= 6.054 X 10⁻³A. =6.054 X 10⁻¹³ m
frequency of photon = 3 x 10⁸/6.054x 10⁻¹³
= .4955 x 10¹⁶Hz.
= 4.955 x 10¹⁵ Hz

Answer:
Explanation:
7.0g is 
the acceleration due to gravity.
Given that 
, acceleration can be calculated as:
Since circular motion is involved and our radius of curvature is given as,
, <em>centripetal acceleration </em>is given by the formula:
.
