A 2750 kg helicopter flies horizontally at constant speed. Air resistance creates a 7510 n backward force. What is the magnitude of the lift force created by the propellers
Answers
Answer:
Explanation:
Let lift force F be created by propellers at angle of Ф with the horizontal .
The vertical component of this force will balance the weight of helicopter and horizontal component will balance the air resistance .
F sinФ = mg = 2750 x 9.8 = 26950 N
F cosФ = 7510 N
Squaring and adding ,
F² = 26950² + 7510²
= 726302500 + 56400100
= 782702600
F = 27976.82 N .

A wave has a wavelength of 0.02m and period of 8.0*10^-2 seconds. calculate it's speed. (showing working)
Answers
Answer:
[tex]v = 0.25m/s[/tex]
Explanation:
Given
[tex]\lambda = 0.02m[/tex] --- Wavelength
[tex]T = 8.0 * 10^{-2}s[/tex] --- Period
Required
Determine the velocity of the wave
This is calculated using:
[tex]v = \frac{\lambda}{T}[/tex]
[tex]v = \frac{0.02m}{8.0*10^{-2}s}[/tex]
[tex]v = \frac{0.02m}{8.0*0.01s}[/tex]
[tex]v = \frac{0.02m}{0.08s}[/tex]
[tex]v = 0.25m/s[/tex]
Hence, the velocity is 0.25m/s

1. An elephant has a mass of 5,500 kg. What is the elephant's weight?
Write equation here:
Answers
Answer:
12125.42 Lbs.
Explanation:
The weight of the elephant is 53,900 N
The given parameters;
mass of the elephant = 5,500 kg
The weight of the elephant is calculated as;
Weight = mg
where;
m is the mass of the elephant
g is acceleration due to gravity = 9.8 m/s²
The weight of the elephant is calculated by substituting the given parameters;
Weight = 5,500 x 9.8 = 53,900 N
Thus, the weight of the elephant is 53,900 N

Transforme: a) 2 km em m b) 1,5 m em mm c) 5,8 km em cm d) 0,4 m em mm e) 27 mm em cm f) 126 mm em m g) 12 m em km
Answers
Answer:
a) 2000 m
b) 1500 mm
c) 580000 cm
d) 400 mm
e) 2.7 cm
f ) 0.126 m
g) 0.012 km
Explanation:
Transform
a) 2km to m
1 km = 1000m
hence : 2 km = 2 * 1000 = 2000 m
b) 1.5m to mm
1 m = 1000 mm
hence: 1.5 m = 1.5 * 1000 = 1500 mm
C) 5.8 km to cm
1 km = 100000 cm
hence ;5.8 km = 5.8 * 100000 = 580000 cm
D) 0.4 m to mm
1 m = 1000 mm
hence; 0.4 m = 0.4 * 1000 = 400 mm
E) 27 mm to cm
1 mm = 0.1 cm
hence ; 27 mm = 27 * 0.1 = 2.7 cm
F) 126mm to m
1 mm = 0.001 m
hence ; 126 mm = 126 * 0.001 = 0.126 m
G) 12m to Km
1 m = 0.001 km
hence ; 12 m = 12 * 0.001 = 0.012 km
