Answer:
i) 0.7
ii) 1.39
iii) 0.6
Next time, when compiling a Physics question, ensure you put the unit of each measurement. 
Explanation:
i) T = time of flight =   
where u = speed = 4, A = 60 and  g = acceleration due to gravity = 10 (It is a constant);
Subsituting the values, we have: T =  = 0.7
 = 0.7
ii) distance travel = Range =  R = 
where u = speed = 4, A = 60 and  g = acceleration due to gravity = 10 (It is a constant);
Subsituting values, we have: R =  = 1.39
 = 1.39
iii) Maximum Height = H = 
where u = speed = 4, A = 60 and  g = acceleration due to gravity = 10 (It is a constant);
Subsituting values, we have:  = 0.6
 = 0.6
 
        
             
        
        
        
Answer:
1340.2MW
Explanation:
Hi!
To solve this problem follow the steps below!
1 finds the maximum maximum power, using the hydraulic power equation which is the product of the flow rate by height by the specific weight of fluid
W=αhQ
α=specific weight for water =9.81KN/m^3
h=height=220m
Q=flow=690m^3/s
W=(690)(220)(9.81)=1489158Kw=1489.16MW
2. Taking into account that the generator has a 90% efficiency, Find the real power by multiplying the ideal power by the efficiency of the electric generator
Wr=(0.9)(1489.16MW)=1340.2MW
the maximum possible electric power output is 1340.2MW
 
        
             
        
        
        
The term “electric field” refers to the physical field that surrounds electrically charged particles and acts to either attract or repel all other charged particles in the field (also known as an E-field). 
It can also refer to the physical field surrounding a system of charged particles. Electric fields are composed of electric charges and time-varying electric currents.
Both electric and magnetic fields are manifestations of the electromagnetic field, one of the four fundamental interactions (sometimes known as forces) of nature.
Electrical technology makes use of electric fields, which are significant in many branches of physics. 
For instance, in atomic physics and chemistry, the electric field acts as an attractive force to hold atoms’ atomic nuclei and electrons together. It is also the force that causes atoms to chemically link together to form molecules.

Answer:
The Principle of Progression
(I searched it up since I never learned this)
Explanation:
The principle of progression states that a person should start slowly and increase exercise gradually. Since Mandy is just getting started on her exercise routine, she should begin with a few workouts over a large span of time, then work her way up so she can do more workouts in a shorter span of time.
 
        
             
        
        
        
The answer is 5. To find the advantage you just divide 20 by 4.
