Answer:

20 degrees.

Explanation:

From Snell’s law of refraction:

sinθ1•n1 = sinθ2•n2

where θ1 is the incidence angle, θ2 is the refraction angle, n1 is the refraction index of light in medium1, and n2 is the refraction index for virgin olive oil. The incidence angle of the red light is θ1 = 30 degrees.

The red light is in air as medium1, so n1 (air) = 1.00029

So, to find θ2, the refracted angle:

sinθ1•1.00029 = sinθ2•1.464

sin(30)•1.00029 / 1.464 = sinθ2

0.5•1.00029 / 1.464 = sinθ2

sinθ2 = 0.3416291

θ2 = arcsin(0.3416291)

θ2 = 19.976 degrees

To the nearest degree,

θ2 = 20 degrees.

The energy of the incident electron in keV is 5.51× 10—²² keV.

Capacity or ability to do work is termed energy. Energy exists in various forms. It can be in the form of mechanical, potential, thermal, kinetic, and many other forms. Joules is the SI of the energy. The potential energy of a system is defined as the energy stored due to its position. While kinetic energy is defined as the energy

stored due to its position.

Radius1 of the trajectory = 1.00 cm

Radius2 of the trajectory = 2.4 0 cm

The magnitude of the uniform magnetic field = 0.0440 T

A Uniform magnetic field is perpendicular to the trajectories.

The velocity of the incident electron is,

v =  \frac{eBR}{m}

The energy of the incident electron is,

K =  \frac{1}{2} mv ^{2}

K =  \frac{1}{2} \frac{(eBR)}{m}^{2}

The energy in keV is,

1-kilo electron volt = 1000 electron volts

1 keV = 1000 eV

1 \: eV =  \frac{1}{1000} \:  keV

= \frac{ K}{1000}

=  \frac{eB ^{2} R ^{2} }{2000m}

= 5.51 \times 10 ^{ - 22}  \: keV

Therefore, the energy of the incident electron in keV is 5.51× 10—²² keV.

The equation of trajectory of a projectile is y=10x-(5/9)x^2 if we assume g=10m/s^2, the range of projectile in meters is?
Morgarella [4.7K]

Answer:

18 m

Explanation:

y = 10x − 5/9 x²

When the projectile lands, y=0:

0 = 10x − 5/9 x²

0 = x (10 − 5/9 x)

x = 0, 18

The range of the projectile is 18 m.
