Answer:

C

Explanation:

C would make the most sense because the problem with fossil fuels is the fact that it emits greenhouse gases that warm up the earth over a long period of time as the climate has changed because of it.

A person who weighs 864 N is riding a 85-N mountain bike. Suppose the entire weight of the rider plus bike is supported equally
svetoff [14.1K]

Answer:

A=60.06 x 10⁻⁵ m²

Explanation:

Given that

Weight of the person = 864 N

Weight of the bike = 85 N

The total weight ,car + bike ,Wt= 864 + 85 N

 Wt = 949 N

2 p = 949 N

The weight on the each tire(F) = 474.5  N

P = 7.9 x 10 ⁵  Pa

We know that

Force = Pressure x Area

F= P A

By putting the values

474.5 =  7.9 x 10 ⁵  A

A=60.06 x 10⁻⁵ m²

Therefore area of contact A

A=60.06 x 10⁻⁵ m²

A lightbulb has an efficiency of 13.1%.How much light energy (not heat energy) is generated by the bulb every second if the bulb
maw [93]

Answer:

1.048 W

Explanation: Given that a lightbulb has an efficiency of 13.1%.How much light energy (not heat energy) is generated by the bulb every second if the bulb has a power pf 8W?

The input power = 8W

The output power = ?

The efficiency = 13.1%

Using the formula below:

Efficiency = (power output / power input) × 100

13.1 = (Power output / 8 ) × 100

0.131 = power output / 8

Cross multiply to make the power output the subject of formula

Power output = 0.131 × 8

Power output = 1.048 W

Therefore, the light energy (not heat energy) generated by the bulb every second is 1.048 W
