Answer:
The incidence angle is 0.145°.
Explanation:
Given that,
Distance due to east = 119 m
Distance due to north= 47.0 km
We need to calculate the incidence angle
Using formula of incidence angle
Where, y = distance due to north
x = distance due to east
Put the value into the formula
Hence, The incidence angle is 0.145°.
Answer:
Nebulae contribute more to stellar formation than other regions because:
Explanation:
A.They have an unlimited supply of hydrogen.
B. They are believed to be rich in hydrogen and helium.
C. They have a three strong gravitational pull.
This are the reasons that Nebulae contribute more to stellar formation than other regions.
Work is the product of force and displacement. whereas power is the rate of work done with respect to Time.
Answer:
balanced forces external forces
Explanation:
A body that is under a network of balanced external forces will experience no resultant force at all, since all the forces cancel themselves out. A body that is moving with this type of force will experience no acceleration, since there is no force acting on them. This lack of acceleration means that the body maintains a constant velocity if it is already in motion, or zero when the body is at rest.
