Answer:
30 m/s
Explanation:
A boat moves initially at 10 m/s
The boat accelerates at 2 m/s^2 for 10 seconds
We are required to calculate the final velocity (v)
Therefore the velocity of the boat can be calculated as follows
v = u + at
u= 10 m/s
a= 2 m/s^2
t= 10 seconds
v= 10 + 2(10)
v= 10 + 20
= 30 m/s
Hence the velocity of the boat after 10 seconds is 30 m/s
Answer:
A goal.
Explanation:
This is clearly seen to be a scenario of a sporting event. It is seen to have certain set down rules that it is been strictly played by. In different occasions, it is seen to favour an opposing or defending side. In the case here where the ball did not touch or foul anyone after its hit on the woodwork, and been shot into the net, it can be counted to be a goal. There are different rules which ranges from penalty to offsides, to throw-in etc which makes the game lively and controlled very well.
Part 'A'- the focal length would be 7.07mm. Part 'B' - the diopters would be 0.5 diopters. Part 'C' - the lens would be a converging lens.
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Despite injury or disease, the cornea can still repair itself quickly. However, there are situations where damage is too severe for the cornea to heal on its own – such as with a deep injury to the cornea. The following symptoms may indicate that the cornea has sustained a substantial infection, injury or disease: Blurred vision Pain Redness.
Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 diopters.
