explanation
We want to find
sin^{-1}(0.61)sin
−1
(0.61)
We can use at least a scientific calculator to find the value of the given expression.
The sine inverse function is a secondary function.
So you press SHIFT then press Sin
to access the sine inverse function and then type 0.61 in it.
Close the parenthesis and press "="
This will give you the value.
sin^{-1}(0.61)=37.5895sin
−1
(0.61)=37.5895
We round to the nearest tenth to get,
sin^{-1}(0.61)=37.6\degreesin
−1
(0.61)=37.6°
The correct answer is that the surface winds will get stronger.
The observation point on Earth and the two stars form a triangle. The two sides of the triangle are 23.3 ly and 34.76 ly and their included angle is 76.04°. We can use the cos rule to find the third side, which is the distance between the two stars.
c² = a² + b² - 2abCos(C)
c² = (23.3)² + (34.76)² - 2(23.3)(34.76)Cos(76.04)
c = 36.88 light years.
Explanation:
It is given that,
Mass of an object is 13 kg
We need to find the mass of this object on the surface of Jupiter.
The mass of an object is the amount present in it. It it independent of location. It mass remains the same at Jupiter as well. Its does not depend on the gravity on that surface.
Hence, its mass will remain 13 kg on the surface of Jupiter.
Power = Work/time
Work= energy
Potential energy =mxgxh
Power=mxgxh/t
Power=68x10x7/9
Power=529 watts
