A person stands 35.0 m from a flag pole. With a protractor at eye level, he finds that the angle to the top of the flag pole is
Phoenix [80]

Answer:

The flag is 16.321 meters high.

Explanation:

The situation is represented in the attached figure

In the figure we have

tan(\theta )=\frac{H}{D}

Given that

θ = 25.0 degrees

D = 35.0 meters

Applying values in the above equation we have

tan(25)=\frac{H}{35.0}\\\\\therefore H=35.0\times tan(25^{o})=16.321meters

What must happen to the electrons in a material to create an electric current?
Nesterboy [21]
<span>The electrons need to migrate from a region of lower electric potential to a region of higher electric potential. This flow of electrons is known as electron current (which is contrary to the widely-accepted perspective of conventional current).</span>

If a second particle, with the same electric charge but ten times as massive, enters the field with the same velocity v ⃗ , what
masya89 [10]

Answer:

Explanation:

When an moving electric charge passes through a uniform magnetic field

its motion becomes circular .

If m be the mass v be the velocity , q be the charge on the mass B be the magnetic field and R be the radius of circular path

force on the moving charge created by magnetic field

= B q v

Centripetal force required for circular motion

= m v² / R

For balancing

B q v = m v² / R

v = B q R / m

Time period of rotation

T = 2π R / v

= 2 π R m / B q R

= 2 π  m / B q

For first particle

T₁ =  2 π  m₁ / B q₁

For second  particle

T₂ =  2 π  m₂ / B q₂

q₁ = q₂ and 10 m₁ = m₂ ( given )

Putting the values in second equation

T₂ =  2 π  10 m₁ / B q₁

= 10 x 2 π m₁ / B q₁

= 10 T₁

Given T₁ = T

T₂ = 10 T
