Speed = (distance) / (time)
Speed = (100 mi/2 hr)
Multiply by a fraction equal to 1 :
Speed = (100 mi/2 hr) x (1 hr/60 min)
Speed = (100 x 1 / 2 x 60) (mi-hr/hr-min)
Speed = (100 / 120) (mi / min)
Speed = 5/6 mi/min
<em>Speed = 0.833... mi/min</em>
Answer:
the correct answer is c) 23 g
Explanation:
The heat lost by the runner has two parts: the heat absorbed by sweat in evaporation and the heat given off by the body
Q_lost = - Q_absorbed
The latent heat is
Q_absorbed = m L
The heat given by the body
Q_lost = M 
ΔT
where m is the mass of sweat and M is the mass of the body
m L = M c_{e} ΔT
m = M c_{e} ΔT / L
let's replace
m = 90 3.500 1.8 / 2.42 10⁶
m = 0.2343 kg
reduced to grams
m = 0.2342 kg (1000g / 1kg)
m = 23.42 g
the correct answer is c) 23 g

<h3>What is a transformer?</h3>
A transformer is an electrical device that is used to step up or step down voltage.
The formula for calculating the turns ratio of a transformer is given below.
<h3> Formula</h3>
- a = V/v.......... Equation 1
Where:
- V = Primary voltage
- v = Secondary voltage
- a = Turns ratio of the transformer
From the question,
Given:
Substitute the values above into equation 1
Hence, The turn ratio of the transformer is 40.
