The diagram below shows a light ray from a pencil hitting a mirror. An upright pencil sits to the left of a mirror, which is con

vex facing left. An arrow from the tip of the pencil runs to the center of the mirror. Line 1 runs from the point reflection at an acute angle below the first arrow. Arrow 2 runs at an acute angle above the first arrow. Arrow 3 runs perpendicularly up from the point reflection. Arrow 4 runs through the mirror down at an obtuse angle pointing toward a distant point on a line running from the base of the pencil. Which ray shows the correct direction of the reflected ray? 1 2 3 4

What force causes a 1-kg mass to accelerate at a rate of 1 meter per second each second?
Zigmanuir [339]

Answer:

F=1N

Explanation:

Conceptual analysis

To solve this problem we apply Newton's second law:

The acceleration of an object is proportional to the force F acting on it and inversely proportional to its mass m.

a = F / m

Where,

F = m * a Formula (1)

F: Force in Newtons (N)

m: mass in kg

a: acceleration in m/(s^2)

a = v / t  Formula (2)

v: speed in m/s

t: time in seconds (s)

Known information

We know the following data:

m = 1kg

v = 1 m/s

t = 1s

Development of the problem:

In the Formula (2): a = \frac{\frac{1m}{s}}{1s} = 1 \frac{m}{s^2}

In the Formula (1): F=1kg* 1 \frac{m}{s^2}=1N

Directions: I answer all the questions listed below.
anzhelika [568]

Answer:

The compression ratio is 10

Explanation:

Given

V_d = 450cm^3 --- swept volume

V_c = 50cm^3 --- compression volume

Required

Determine the compression ratio (CR)

This is calculated as:

CR = \frac{V_d + V_c}{V_c}

CR = \frac{450+50}{50}

CR = \frac{500}{50}

CR = 10

you stretch a spring by a distance of 0.3 m. the spring has a spring constant of 440 n/m. when you release the spring, it snaps
Alina [70]

Answer:

19.8 J

Explanation:

According to the law of conservation of energy, the total mechanical energy of the spring (sum of kinetic energy and elastic potential energy) must be conserved:

K_i + U_i = K_f + U_f (1)

where we have

K_i is the initial kinetic energy of the spring, which is zero because the spring starts from rest (2)

U_i is the elastic potential energy of the spring when it is fully stretched

K_f is the kinetic energy of the spring when it reaches the natural length

U_f is the elastic potential energy of the spring when it reaches its natural length, which is zero because the stretch in this case is zero (3)

So

U_i = \frac{1}{2}k(\Delta x_i)^2

where

k = 440 N/m is the spring constant

\Delta x_i = 0.3 m is the initial stretching of the spring

Substituting,

U_i = \frac{1}{2}(440)(0.3)^2=19.8 J

And so using eq.(1) and keeping in mind (2) and (3) we find

K_f= U_i = 19.8 J
