The angle of incidence for a ray of light passing through the centre of curvature of a concave mirror is.
evablogger [386]

The angle of incidence for a ray of light passing through the center of curvature of a concave mirror is 0°.

The angle of incidence is the angle between the surface's normal and the incident ray. For a concave mirror, the normal of the surface is along the center of the curvature, and a ray of light passed through a center of curvature passes through the normal of the surface.

The ray of light retreats its path making a zero angle of reflection. The law of reflection state that the angle of incidence is equal to the angle of reflection; therefore, the angle of incidence of a concave surface passed through the center of curvature is zero degrees.

A baseball pitcher throws a baseball horizontally at a linear speed of 49.4 m/s. Before being caught, the baseball travels a hor
RideAnS [48]

Answer:

v = 3.61 m/s

Explanation:

As we know that ball travels horizontal distance of 24.7 m with uniform speed 49.4 m/s

so we will have

t = \frac{x}{v_x}

t = \frac{24.7}{49.4}

t = 0.5 s

now in the same time ball is turned by angle

\theta = 52.7 rad

now we know that

\theta = \omega t

52.7 = \omega (0.5)

\omega = 105.4 rad/s

now the tangential speed of a point at equator is given as

v = r\omega

v = 0.0343(105.4)

v = 3.61 m/s

A man pushes a shopping cart across a level floor. What force resists the effort force? A) gravity B) friction C) the normal for
Kipish [7]

Answer:

B) Friction

Explanation:

Friction is a force that acts when an object is sliding along a surface. Microscopically, this force is due to the fact that the two surfaces are not perfectly smooth, but they have "imperfections" that cause a force that opposes the motion of the object.

For an object sliding on a flat surface, the force of friction has magnitude:

F_f = \mu_k mg

where

\mu_k is the coefficient of kinetic friction

m is the mass of the object

g is the acceleration of gravity

The direction of the force of friction is always opposite to the direction of motion of the object.

In reality, friction also acts if the object is at rest and it is pushed by a force; in this case, we talk about static friction, and its magnitude is

F_f = \mu_s mg

where \mu_s is called coefficient of static friction, and it is generally larger than the coefficient of kinetic friction.
