Answer:

They are reflected back at the same angle they came in

Explanation:

When parallel light rays hit a convex mirror they reflect outwards and travel directly away from an imaginary focal point (F). Each individual ray is still reflecting at the same angle as it hits that small part of the surface.

A train pulls the boxcars. What are the vertical forces present? (1 point)

Greeley [361]

The vertical forces present in a boxcars being pulled by a train are weight and pull of air on the boxcars.

The forces exerted on an object can be resolved into horizontal and vertical components.

The horizontal components of the forces on an object being pulled include the following;

The frictional force on the object; which tends to reduce the motion,

force dragging the object forward

if the object is inclined to an angle, the horizontal component of the weight

This horizontal force is written as;

$\Sigma F_x = 0\\\\F_x - F_k = ma$

The vertical component of the force on the object include the following;

the weight of the object acting downwards

the pull of air on the object acting upwards

The vertical force on the object is written as;

$\Sigma F_n = 0\\\\F_n - W = 0$

Thus, the vertical forces present in a boxcars being pulled by a train are weight and pull of air on the boxcars.

A particle that has a charge of 7.4 μC moves with a velocity of magnitude 3 × 105 m/s along the +x axis. It experiences no magne

sweet [91]

Answer:

Explanation:

F = qvB

Where F equal to the magnetic force on the particle.

q = charge on the particle

v = velocity of the particle

B =Magnetic field

F = 0.520N

q = 7.4 μC = 7.4×10-⁶C

v = 3×10⁵m/s

B= ?

B = F/qv

B = 0.520/(7.4×10-⁶ ×3×10⁵)

B = 0.234T.
