Speed can be thought of as the rate at which an object covers distance. ... Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour........?
Answer:
EN PAISES TERCERMUNDITASS COMO EL MIO NO ENSEÑAN ESTAS COSAS ._.
Explanation:
Answer:
Δm Δt> h ’/ 2c²
Explanation:
Heisenberg uncertainty principle, stable uncertainty of energy and time, with the expressions
ΔE Δt> h ’/ 2
h’= h / 2π
to relate this to the masses let's use Einstein's relationship
E = m c²
let's replace
Δ (mc²) Δt> h '/ 2
the speed of light is a constant that we can condense exact, so
Δm Δt> h ’/ 2c²
Answer:
Part a)
so here the angle made by the string is independent of the mass
Part b)
Explanation:
Part a)
Let the string makes some angle with the vertical so we have force equation given as
so we will have
so here the angle made by the string is independent of the mass
Part b)
Now from above equation if we know that angle made by the string is
so we will have
