Ilia_Sergeevich [38]2 years ago

7 0

Explanation:

I. Direction - Towards the negative x axis since there's a '+' sign b/n π/4 & X

II. y = Asin(wt + kx)

k = 2π/ለ = 1

ለ = 2πcm = 6.29cm or 6.29×10^-2m in meter

i suggest using the one in cm.

A typical current in a lightning bolt is 103 a. estimate the magnetic field 9 m from the bolt (in t). (enter the magnitude.)

kifflom [539]

The magnetic field is

$2.288 \times 10 {}^{ - 6} T$

what is magnetic field?

Magnetic field is defined as the relationship between the permittivity of free space,the magnitude of electric current,and distance.

Here is the formula,

$B = \frac{µ0l }{2π R}$

here,

B= magnitude of the magnetic field

l= magnitude of electric current

R=distance

µ0=permittivity of free space

Now,using above formula we can calculate the magnetic field

$B = \frac{µ0l }{2π R}$

$\frac{4\pi \times 10 {}^{ - 7}. \frac{m}{a} \times 103 }{2\pi \times (9m)}$

$= 2.288 \times 10 {}^{ - 6} T$

Thus,the magnetic field is

$= 2.288 \times 10 {}^{ - 6} T$

A car travels at a constant speed up a ramp making an angle of 28 degrees with the horizontal component of velocity is 40 kmh^-1

Hoochie [10]

Answer:

Vx = 35.31 [km/h]

Vy = 18.77 [km/h]

Explanation:

In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.

$v_{x} = 40*cos(28)\\V_{x} = 35.31 [km/h]$

In order to find the vertical component, we must use the sine function of the angle.

$V_{y}=40*sin(28)\\V_{y} = 18.77 [km/h]$

What is the difference between longitudinal and transverse waves?

Greeley [361]

Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave. ... Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.

A 20 kilogram ball rolls down a 10 meter ramp at the rate of 15 meters per second. The kinetic energy is joules

kobusy [5.1K]

Answer:2250J

Explanation:

mass(m)=20kg

velocity(v)=15m/s

Kinetic energy=(m x v^2)/2

Kinetic energy =(20 x 15^2)/2

Kinetic energy =(20x15x15)/2

Kinetic energy=4500/2

Kinetic energy=2250J
