Explanation

A nurse works at a hospital.

Teacher – works at a school,

Explanation

The tallest TV tower in Asia is the Tokyo Skytree.

It stands at 634 meters (2,080 ft) and is located in Tokyo, Japan. 

A) Tokyo Skytree: 634 meters (tallest)

B) Canton Tower: 604 meters (second tallest in the world at the time of its completion, but surpassed by Tokyo Skytree)

C) Oriental Pearl TV Tower: 468 meters

D) Kuala Lumpur Tower: 421 meters (although this is a common measurement, another source lists it at 1,381 ft or ~421m, as opposed to the 1381 ft from Fact Monster) 

Explanation

In common logarithms, the mantissa is the fractional part of the log value and is always taken as a positive decimal between 0 and 1.

Explanation

 The mass of an electron is a standard physical constant in physics.

- Its accepted value is:

  mₑ = 9.109 × 10⁻³¹ kilograms

Explanation

Given: sinθ + cosθ = 1

We need to find: sinθ - cosθ

---

Solution:

Square both sides of the given equation:  

(sinθ + cosθ)² = 1²  

sin²θ + 2 sinθ cosθ + cos²θ = 1

Since sin²θ + cos²θ = 1, substitute:  

1 + 2 sinθ cosθ = 1  

2 sinθ cosθ = 0  

sinθ cosθ = 0

---

Now, square the expression we want:  

(sinθ - cosθ)² = sin²θ - 2 sinθ cosθ + cos²θ  

= 1 - 2 sinθ cosθ  

= 1 - 0  

= 1

So, (sinθ - cosθ)² = 1  

=> sinθ - cosθ = ±1

Explanation

- 36 = 6²  

- 16 = 4²  

- 64 = 8²  

- 49 = 7²  

49 is the different number because it’s the only odd number, while the rest are even

Explanation

If smoke is coming from the kitchen, the most likely reason is Fire, specifically a fire from burning food or overheating cooking oil.

While

Less likely, an electrical fire from a faulty appliance, 

A clogged and dirty extractor fan causing smoke to build up, or even an appliance overheating, are also possible causes. 

Explanation

 The centripetal force keeps an object moving in a circular path.  

- Its formula is F = mv² / r, where:  

  - m = mass of the object  

  - v = velocity  

  - r = radius of the circular path  

- It always acts towards the center of the circle.  

- Example: A stone tied to a string and rotated in a circle — the string provides centripetal force.
