Questions from Tina Hang – Secondary 1 Maths Questions

Question 1: y is directly proportional to x2 and y = a for a particular value of x. Find an expression for y in terms of a, when this value of x is doubled.

Question 2: The braking distance of a vehicle is directly proportional to the square of its speed. When the speed of the vehicle is b m/s, its braking distance is d m. If the speed of the vehicle is increased by 200%, find the percentage increase in its braking distance.

Hi,

A)How do we explain fully the greenhouse effect?

B) The greenhouse is a “model” of the greenhouse effect. What does the greenhouse and plants inside represent?

Greenhouse- Atmosphere?

Plants – Greenhouse gas or earth surface?

Thanks.

The greenhouse effect is an effect that is caused by greenhouse gases.e.g.carbon dioxide,chlorofluorocarbons.these gases which are also known as greenhouse gases,trap heat from escaping into the atmosphere outside of Earth thus he heat remains on Earth.Thus Earth would be hotter and this may lead to global warming…hope this helps.you may also search online for greenhouse effect if this explanation doesn’t help….
