Answer:
A
Explanation:
A. The molecules that make up olive oil are longer than those that
make up alcohol, so they have more resistance to sliding past one
another.
Olive oils are unsaturated fats with many carbons whereas, alcohols are typically short with very few carbons.
Explanation:
a) How much work is done by gravity?
- w = f x d
- w = 950 x 10 x 5.5 = 52250j
b) How much work is done by tension?
- v²=u²+2as
- 0.75²=0.25²+2a x5.5
- 0.56=0.06+2a x5.5
- 2a x5.5 = 0.56 - 0.06
- 2a x 5.5 =0.5
- 11a=0.5
- a = 0.5/11 = 0.05m/s²
w = f x d
w = 950 x 0.05 x 5.5 = 261.25j
Answer:
a) 316880878140.2895 Joules
b) 1056.26 Joules
c) 372.80103310622 km²
Explanation:
Energy consumption
Average rate of electrical energy consumption is 316880878140.2895 Joules
Total population = 300 million
Each person consumes 1056.26 Joules.
Efficiency = 0.85
Power from Sun
Area
Converting to km²
Area required to collect the electrical energy used in the United States is 372.80103310622 km²
Mechanical waves, it needs a certain medium to travel through. This medium can be a solid, liquid and gas. There are three types of mechanical waves namely, sound wave, water, and waves through the ropes.
A longitudinal wave is a wave that vibrates in a parallel direction with the motion. Also known as a compression wave. Both mechanical and longitudinal waves produce a sound.
Option D would be the correct one!
