Answer:
The length of the bridge during the hottest part of summer is 
Explanation:
From the question we are told that
The length of the steel bridge is 
The temperature for this length is 
The temperature at summer 
The coefficient of linear expansion is 
Generally the change in length of the steel bridge is mathematically represented as
Substituting value
The length of the bridge in summer is mathematically evaluated as
Substituting values
Answer:
The value of b 0.7351 kg/m
Explanation:
Given that;
Mass of sky diver = 82 kg
Velocity = 33.4 m/s
f = −bv²
It is a resistance force, therefore the negative sign is ignored.
since; f = mg
∴ mg = bv²
b = mg / v
² ........ (1)
At terminal velocity a = 0
Put parameters in (1)
b = (82 × 10) / (33.4)²
b = 820 / 1,115.56
b = 0.7351
Iso-kinetic exercises cannot be performed at home by an individual because they require specific machines that enable to exercise at a constant speed with professional guidance.
<u>Explanation
:</u>
Iso-kinetic exercises are that kind of training regimes that require a constant pace to strengthen your muscles with the help of machines with significant specifications.
The machines involved in iso-kinetic exercises control your pace with variable resistance throughout the session and hence, it’s not a cup of tea for an individual to trace his/her performances and the respective improvements.
So, before going for a iso-kinetic schedule, be sure to have a word with your physiotherapist to train well with the machines under the specifications that can better suit your body and its requirements.
A major obstacle to developing a good human relations skill is that : few person have a common interest a communication between two people will be a lot easier if they have common interest because a person tend to like other person that are similar to him (whether it's race, background , or common interest).
