Answer:
Planck's radiation law, a mathematical relationship formulated in 1900 by German physicist Max Planck to explain the spectral-energy distribution of radiation emitted by a blackbody (a hypothetical body that completely absorbs all radiant energy falling upon it, reaches some equilibrium temperature, and then reemits
Explanation:
Answer:
a = 12.2 m/s²
Explanation:
Given: 5 kg, 61N
To find: Acceleration (a)
Solution:
A = F ÷ m
= 61 ÷ 5
= 12.2 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
Answer:
vf = 4.01 m/s
Explanation:
According to the law of conservation of energy:
where,
vf = final speed of ball at top of the ramp = ?
vi = initial speed of ball = 2.62 m/s
g = acceleration due to gravity = 9.81 m/s²
h = height = 0.47 m
Therefore,
<u>vf = 4.01 m/s</u>
