Answer:
The correct option is;
A. proper protection
Explanation:
Motorcycle riders ride the motorcycle while at some level of speed while having the entire body exposed to be a major part of any collision.
Injuries sustained from motorcycle accidents are several times more severe than injuries sustained by occupants of a car that is fully protected by the metallic panel in the same and even more serious accident scenarios
Hence, motorcycle riders require adequate protection by putting on available motorcyclist safety gear
Therefore, to reduce the risk of severe injury n a crash, motorcycle riders require proper protection.

It was determined by the forensic engineers that the historic collapse of the Minneapolis Interstate Bridge was due to design and construction flaws. It led to the collapse of the structure.
<h3>What is the Minneapolis Interstate Bridge?</h3>
The Minneapolis Interstate Bridge is a well-known bridge that was constructed in Minneapolis city in 1967.
It has been demonstrated that the collapse of this bridge constructed in Minneapolis was due to its inadequate load capacity.
In architecture, it is fundamental to measure the amount of weight that a structure (in this case, a bridge) can sustain in a given period of time.

Answer:
weight of astronaut 
Explanation:
Given data:
astronaut weight is = 125 lbs
distance of shuttle from surface of earth is 200 mils
we know that 
where G, m_1, m_2 are constant value, so we have
radius of earth is 4000 miles
where r_2 = 4000 + 200 = 4200 miles
Answer:
The power required to cool the water is 1.11Kw.
Hence the correct option is (b).
Explanation:
Power needed to cool down is equal to heat extract from the water.
Given:
Volume of water is 1 liter.
Initial temperature is 100C.
Final temperature is 20C.
Time is 5 minutes.
Take density of water as 100 kg/m3.
Specific heat of water is 4.186 kj/kgK.
Calculation:
Step1
Mass of the water is calculated as follows:
m=1kg
Step2
Amount of heat extraction is calculated as follows:
Q=334880 j.
Step3
Power to cool the water is calculated as follows:
P=1116.26W
or
P=1.11 Kw.
Thus, the power required to cool the water is 1.11Kw.
Hence the correct option is (b).
