Self<span>-actualization brings about self-satisfactions and a sense of
self-worth.
When someone is highly creative and creates something successfully, he or she
feels motivated and feels that he or she has finally achieved his or her goal.
Nothing better than this can lead to self</span>-actualization. </span>
Answer:
The distance at which nose of the vehicle will the shock wave impinge upon the ground is approximately 23km
Explanation:
Let
u be Mach angle
M be Mach Number = 2.5
h be altitude = 10km
d be distance between nose of the vehicle with which the shock wave impinge upon the ground
Using;
Sin u = 1/M
u = arcSin (1/M)
u = arcSin (1/2.5) = 23.58°
Using angle at a point rule = 90°
90 - 23.58 = 66.42°
Tan A = opp/adj
Tan 66.42° = d/10
2.2911 * 10 = d
d = 22.911km ≈ 23km
Answer:
Seafloor spreading is a geological process that occurs in the ocean. It is occurs due to divergent plate tectonics. As, lithospheric plates of the ocean moves away from each other, the heat from the mantle liberates as convection currents that decreases the density of the crust. The less dense material rises, resulting the elevation of the seafloor, which is called as sea floor spreading.
Explanation:
Electromagnets
When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet. A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.
