Answer:
It's leggings. They help protect the lower legs and feet from heat hazards like molten metal and welding sparks.
Answer:
percentage change in volume = 0.00285 %
Explanation:
given data
bulk modulus = 3.5 × 
N/m²
bulk stress = 
N/m²
solution
we will apply here bulk modulus formula that is
bulk modulus = 
...............1
put here value and we get
3.5 × = 
solve it we get
bulk strain = 2.8571 × 
and
bulk strain = 
so that percentage change in volume is = 2.8571 × × 100
percentage change in volume = 0.00285 %
Efficiency is the minimum use of energy to accomplish the task. The wasted energy will be 375 J when 750 J of energy is given.
<h3>What is wasted energy?</h3>
Wasted energy is energy that is not useful when the transformation in the system occurs.
Total energy = 750 J
The efficiency of the system = 50 %
Output work (OW) is calculated as:
Efficiency = output work ÷ input work × 100%
750 × 50 = 100 OW
OW = 375 J
Wasted energy = Total energy - output work
= 750 - 375
= 375 J
Therefore, the machine is 50 % inefficient and has wasted energy of 375 J.

Answer:
1. James will attack by generating a random private key XD and a corresponding public key YD.
2. Jane transmit YA to another person called Alex.
3. James intercept YA and transmit YD to jane.
4. Jane receive YD and calculate K1
At this point james and jane thinks they share a secret key but instead james has a secret key k1 to Jane and k2 to alex.
5. Alex transmit another key XA to alex for example.
6. James intercept and calculate k2 and vice versa.
