Sound waves <span>can NOT travel through the vacuum of space?</span>
Answer:
The distance is
Explanation:
From the question we are told that
The smallest shift is
Generally a grid unit is of an arcsec
This implies that 0.2 grid unit is
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
substituting values
Note
So
Answer:
From -15⁰ to 0⁰
H=mc¶
where H= heat absorbed or evolved
m=mass involved
c=specific heat capacity
¶=change in temperature
H=mc¶
Answer:
v = 15 m / s
Explanation:
In this exercise we are given the position function
x = 5 t²
and we are asked for the average velocity in an interval between t = 0 and t= 3 s, which is defined by the displacement between the time interval
let's look for the displacements
t = 0 x₀ = 0 m
t = 3 = 5 3 2
x_{f} = 45 m
we substitute
v = 15 m / s
Answer:
v = 13.79 m/s
Explanation:
given,
mass of ball = 110 g
height = 11 m
ball is released from = 1.3 m
minimum speed = ?
using conservation of energy
Potential energy is conserved in the form of kinetic energy
v = 13.79 m/s
