The Arctic Ocean is the smallest ocean. It is more than five times smaller than Indian and Atlantic Oceans.
Answer:
Given that
The earth spins on its axis once a day and orbits the sun once a year (365 1/4 days)
a)
When earth spins on its axis
We know that earth take 1 day to complete one revolution around its own axis.
T= 1 day = 24 hr = 24 x 3600 s
T=86400 s
We know that
T=2π/ω
ω= 2π/T
ω= 2π/86400
ω=7.27 x 10⁻5 rad/s
b)
When earth revolve around earth
T =365 1/4 days = 365.25 days
T= 365.24 x 86400 s
T=31557600
We know that
T=2π/ω
ω= 2π/T
ω= 2π/31557600
ω=1.99 x 10⁻⁷ rad/s
Answer:
e) True Yes both are constant
Explanation:
Let us propose the solution of the problem before reviewing the statements, we use Newton's second law
F - fr = m a
N- W = 0
N = mg
The equation for the force of friction is
fr = μ N
F - μ mg = m a
F = m (a- μ g)
Now let's review the claims
.a) False. Normal force and friction are constants.
.b) False. Both are constant.
.c) False. Both are constant.
d.) False
e) True Yes both are constant
A wave as long as matter is not being transported
