A vector has an x-component
of 6.15 m and a y-component
of -3.88 m.
Find the magnitude of the
vector.
Answers
Answer:
please find attached file
Explanation:
The magnitude of the vector is 7.27m .
What is magnitude of a vector?The magnitude of a vector is the numerical value of the vector. It is represented by the length of the vector.
When a vector is resolved in two components then it is given by formula,
[tex]A = \sqrt{Ax^{2}+Ay^{2} }[/tex]
Here,
[tex]A_{x} = 6.15\\A_{y} = 3.88[/tex]
A = [tex]\sqrt{6.15^{2}+3.88^{2}[/tex]
A = 7.27m
Hence magnitude of the vector is 7.27m .

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

Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest.
Physical fitness is generally achieved through exercise. Photo shows Rich Froning Jr. – four-time winner of "Fittest Man on Earth" title.
Before the industrial revolution, fitness was defined as the capacity to carry out the day’s activities without undue fatigue. However, with automation and changes in lifestyles physical fitness is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.

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

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

An arrow is fired at 5.20 m s−1 at an angle of 22.0° above the horizontal. Find the horizontal component of the initial velocity, expressing your answer in m s−1 to 2d.P.\
Answers
Answer:
[tex]4.82ms^{-1}[/tex]
Explanation:
We are given that
Initial velocity, u=5.20m/s
[tex]\theta=22^{\circ}[/tex]
We have to find the horizontal component of the initial velocity.
We know that
Horizontal component of velocity=[tex]ucos\theta[/tex]
Using the formula
Horizontal component of the initial velocity=[tex]5.2cos22^{\circ}[/tex]
Horizontal component of the initial velocity=[tex]5.2\times 0.9272[/tex]
Horizontal component of the initial velocity=[tex]4.82ms^{-1}[/tex]
Hence, the horizontal component of the initial velocity=[tex]4.82ms^{-1}[/tex]
