Sum of all forces = mass * acceleration
Ft= tension force
Fw= force of gravity (Fw= mass* acceleration of gravity which is 9.8 this only applies to force of gravity)
Ft- Fw = 0 (there is no acceleration)
Ft = Fw
Ft= m*g
Ft= 0.250kg*9.8m/s
Ft= 2.45N
Answer:
it would be 3
Explanation:
because you have to divide the length by the height of the incline.
Answer:
Explanation:
Energy, E = 4.75 x 10^-19 J
Energy, E = hc/λ
where, λ is the wavelength, h be the Plank's constant and c be the velocity of light.
h = 6.63 x 10^-34 Js
c = 3 x 10^8 m/s
λ = (6.63 x 10^-34 x 3 x 10^8) / (4.75 x 10^-19)
λ = 418.73 nm
So, the colour of light should be violet.
