Answer:
You'd have to show the picture..
Answer:
a
The orbital speed is
b
The escape velocity of the rocket is
Explanation:
Generally angular velocity is mathematically represented as
Where T is the period which is given as 1.6 days =
Substituting the value
At the point when the rocket is on a circular orbit
The gravitational force = centripetal force and this can be mathematically represented as
Where G is the universal gravitational constant with a value
M is the mass of the earth with a constant value of
r is the distance between earth and circular orbit where the rocke is found
Making r the subject
The orbital speed is represented mathematically as
Substituting value
The escape velocity is mathematically represented as
Substituting values

Answer:
it ends when clouds above start to break apart. Some tornadoes only last seconds. Others can last much longer. They come in many shapes and sizes.
Answer:
the activity of thallium is 1.54 kBq .
Explanation:
given,
half life = 3.7 years
R₀ = 10 kBq
time = 10 years
R = 10 × (0.153667)
R = 1.5367 ≈ 1.54 kBq
hence, the activity of thallium is 1.54 kBq .
