Answers

Answer 1

Complete question :

A driver of a car moving with speed 90km/h saw a child on the road 25m ahead of him .he jammed on the brake and bought the car to rest. Calculate the time taken to bring the car to rest and retradation of the car.

Answer:

t = 2 seconds ; retradation = - 12.5 m/s²

Explanation:

Given that :

Final velocity v = 0

Initial Velocity u = 90 km /hr = (90 * 1000)m / 3600s = 90000m/3600s = 25m/s

Distance = 25 m

Using the relation :

v² = u² + 2aS

where, S = distance covered a = retradation

0 = 25² + 2a(25)

0 = 625 + 50a

50a = - 625

a = - 12.5 m/s²

Time taken (t) :

Using :

v = u + at

0 = 25 + (-12.5 * t)

0 = 25 - 12.5t

12.5t = 25

t = 25 / 12.5

t = 2 seconds

1. in 1815, britain became the worlds first superpower. which of these countries could today be considered a superpower?

Answers

China since the fall of the Soviet Union , is referred as an emerging superpower

In 1815, Britain became the world's first superpower. China could today be considered a superpower. Thus, option D is the correct option.

Can China be considered a superpower?

A state or other polity that is thought to be, or to have the potential to soon become, a superpower is considered a prospective superpower. Only the United States meets the requirements to be a superpower at this time. The United States, however, is no longer the only undisputed top superpower and the only hyperpower to rule the globe in every sphere (military, cultural, business, technology, and diplomacy).

China, the European Union, India, and Russia have all been referred to as prospective superpowers since the 1990s. Japan's rapid economic development once led some to view it as a prospective superpower. However, because of ageing populations and economic stagnation, it has lost some of its potential superpower statuses since the 1990s.
