Based on Newton's law of action-reaction, which arrow represents the force that the seat belt would exert on the man's body if he had to slam on the brakes?

Answers

Answer 1

Answer:

c. Y

Explanation:

Newton's third law of motion states that action and reaction are equal and opposite. Hence for every action, there is an equal and opposite reaction.

Considering the system of forces shown in the image, W and Y are  opposite forces. When the driver slams on the brakes, he will be pushed forward towards the windscreen. The force Y exerted by the seat belt keeps him on the drivers seat by moving him backwards towards the seat.

Which is the correct equation for the force applied by a spring?

Answers

Answer:

B. [tex]F = -k*x[/tex]

Explanation:

The force of a spring can be easily calculated using Hooke's law which tells us that the force applied on a spring is equal to the product of the constant of a spring by the compressed or stretched distance of the spring.

That is:

[tex]F = k*x[/tex]

k = spring constant [N/m]

x = distance [m]

How much does a 20 kg rock weigh on Earth where g = 9.8 m/s2?

Answers

Answer:

[tex]\huge\boxed{196\:N}[/tex]

Explanation:

Mass and weight ain't the same thing. So, for calculating weight we would use Newton's 2nd Law of Motion i.e. Force = Mass × Acceleration.

According to question,

The mass is 20kg

Acceleration is 9.8 m/s^2

Putting the given values into the formula,

F = 20 × 9.8

F = 196N

So, the weight of the rock is 196 N

оа

Od
48.3 m/s
-68.4 m/s
84.7 m/s
-57.6 m/s

Answers

Answer:

a= g = - 9.81 m/s2.

The following equations will be helpful:

a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad

When you substitute the specific acceleration due to gravity (g), the equations are as follows:

g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd

If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:

g = vf /t d = 1/2 gt2 vf2 = 2gd

The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.

hope this info helps you out!

How do I calculate how many meters are in 7.2 light years?
The exact question is:
Calculate in meters the distance between a galaxy and the Earth if the distance is equal to 7.2 light years.

Answers

Answer:

68.2 Quadrillion meters

Explanation:

A lightyear is the distance that light travels in one year.

Speed of light is [tex]3*10^8\ m/s[/tex]

So light covers 300,000,000 meters in one second.

One year has 31536000 seconds so , light covers

[tex]9.461*10^{15}\ meters\ in\ one\ year[/tex]

so 7.2 light years is

[tex]7.2*(9.461*10^{15})\\6.82*10^{16}[/tex]

so 7.2 light years is

6.82 x 10^(16) meters or

68.2 Quadrillion meters

A particle is moving with simple harmonic motion of period 8•0 s and amplitude 5•0 m Fine (A). The speed of the particle when it's 3•0 m from the centre of it's motion (B). The maximum speed (C). The maximum acceleration

Answers

Answer:

a. v(1.8) = -3.14 m/s

b. [tex]v_{max} = 3.925\ m/s[/tex]

c. [tex]a_{max} = 3.08\ m/s^2[/tex]

Explanation:

a.

The speed of a particle executing simple harmonic motion is given by the following equation:

[tex]v(t) = -A \omega \ Sin(\omega t)[/tex]

where,

v = velocity = ?

A = Amplitude = 5 m

ω = angular frequency = [tex]\frac{2\pi}{Time Period} = \frac{2\pi}{8\ s}[/tex] = 0.785 s

t = time

First we find time at 3 m by using equation for displacement:

[tex]x = 3\ m = ACos(\omega t)\\Cos((0.785 rad/s)(t)) = \frac{3\ m}{5\ m}\\t(0.785\ rad/s) = Cos^{-1} (0.6)\\t = \frac{0.927\ rad}{0.785\ rad/s}\\t = 1.18 s[/tex]

Therefore,

[tex]v(1.8) = velocity at 3\ m = -A\omega Sin(\omega t)\\v(1.8) = -(5\ m)(0.785\ rad/s)Sin((0.785\ rad/s)(1.18\ s))\\[/tex]

v(1.8) = -3.14 m/s

c.

The maximum speed is given as:

[tex]v_{max} = A\omega\\v_{max} = (5\ m)(0.785\ rad/s)\\[/tex]

[tex]v_{max} = 3.925\ m/s[/tex]

The maximum acceleration is given as:

[tex]a_{max} = A\omega^2\\v_{max} = (5\ m)(0.785\ rad/s)^2\\[/tex]

[tex]a_{max} = 3.08\ m/s^2[/tex]

What is reflection of light and its laws ?​

Answer:

So, put simply, reflection is light bouncing off surfaces. The law of reflection determines how the light bounces off a surface. The law of reflection states that the angle of incidence is equal to the angle of reflection.

The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in geometrical optics are measured with respect to the normal to the surface that is, to a line perpendicular to the surface.

event:
A. the PE must not change.
B. PE (before) = KE (before).
C. energy is conserved.
D. the momentum does not change
PLEASE HURRY

Answers

The total (PE+ KE) before an event is equal to the total (PE+ KE) after the event.

Hence, the correct option is C.

If the total (PE + KE) before an event is equal to the total (PE + KE) after the event, this means that the total energy of the system is conserved. This is known as the principle of conservation of energy.

It is not necessary for the potential energy to remain constant or for the potential energy before the event to equal the kinetic energy before the event. Rather, the total energy (the sum of potential and kinetic energy) of the system must be conserved.

Similarly, it is not necessary for the momentum to remain constant in this case. The conservation of momentum is a separate principle that applies when there are no external forces acting on the system.

Hence, the correct option is C.
