Answer:
b
Explanation:because endothermic contains heat so cookies need heat
Different: The weak nuclear force is responsible for radioactive decay within an atom of a substance, while the electromagnetic force causes electrostatic force between charged particles.
Different: The weak force has a very small range of effectiveness (where the force can be felt) while the electromagnetic force has an infinite range.
Same: Both forces act within an nucleus, or on a nuclear level.
Same: The weak nuclear force is mediated by charged particles called bosons, and the electrostatic force is only present within charged objects
The last one may be a bit of a stretch but I hope this helped a bit!
Answer:
Due to the process of weathering and erosion.
Explanation:
- As the rocks are made of different forms of minerals they may have an igneous, metamorphic or sedimentary origin. Hence the natural stone surfaces can be made of granite, lime, or even shale.
- The process of physical weathering that is called as mechanical weathering of rocks tends to break them apart and leads to the development of crack and small openings.
- The diurnal exposure of bare rocks to extreme temperatures of day and night leads to onion peeling and slowly with water as an agent of erosion lead to cracks in joints of rocks.

1. Ideal Mechanical Advantage (IMA): 9
Explanation:
For a wheel and axle system like the steering wheel, the IMA is given by:
where
is the radius of the wheel
is the radius of the axle
For the steering wheel of the problem, we see that 
and 
, so the IMA is
2. Efficiency: 88.9%
Explanation:
The efficiency of a system is defined as the ratio between the AMA (actual mechanical advantage) and the IMA:
In this problem, AMA=8 and IMA=9, so the efficiency is
