Answer:72,000
Explanation:
Answer:
Angle=70°
Explanation:
Given data
a=2i-5j+k
b=9i-k
To find
Angle Θ
Solution
As we know from dot product rule that
First we need to find a.b
As
i.i=j.j=k.k=1
i.j=i.k=j.k=0
So
Now for |a| and |b|
So the angle is given as
Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
