Answer:
distance between Rome to Sorrento is 240 miles
Explanation:
given data
speed = 80 mph
time = 5 hours
reduce speed = 60 mph
to find out
distance between Rome to Sorrento
solution
let us consider time from Rome to Sorrento is x
we know 8 am to 8 pm total 12 hours and 5 hours in town spend so 12 -5 = 7
so we say that time back is 7 -x
we know distance was same
so distance is speed × time
compare both side distance
80 x = 60 (7-x)
80 x = 420 - 60 x
x = 3
so distance is = 80 (3) = 240 miles
distance between Rome to Sorrento is 240 miles
Answer:
the pressure exerted on the turf when the player lands on his knee is 240,000 N/m².
Explanation:
Given;
combined weight of the players, F = 2400 N
measurement of the player's knee = 0.1 m by 0.1 m
The area of the player's knee is calculated as;
A = 0.1 m x 0.1 m = 0.01 m²
The pressure exerted on the turf when the player lands on his knee is calculated as;
P = F / A
P = (2400 N) / (0.01 m²)
P = 240,000 N/m²
Therefore, the pressure exerted on the turf when the player lands on his knee is 240,000 N/m².
Answer:
23.67 m
Explanation:
We are given;
Frequency; f = 0.3 Hz
Speed; v = 7.1 m/s
Now, formula to get the wavelength is from the wave equation which is;
v = fλ
Where λ is wavelength
Making λ the subject, we have;
λ = v/f
λ = 7.1/0.3
λ = 23.67 m
