The direction of the acceleration is in the same direction as the net force causing it.  F = ma is actually a vector equation in which f and a are both vectors and m is a scalar constant.

A ___ force is not path-dependent and does not change the overall mechanical energy of an object.​

Answers

Answer:

conservative

Explanation:

Nonconservative force is the force that depends on a path, however conservative does not depend on a path and it is not associated with the potential energy. When the work is done by an unconservative force, mechanical energy is added or removed. Friction is the best example for a non-conservative force. When these non-conservative forces are acting, the mechanical energy changes but these are not preserved.

hope this helped!

Answer: conservative

Explanation:

A conservative force is not path-dependent and does not change the overall mechanical energy of an object.​

A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the taken path, e.g. gravitational force or electric force.

A nonconservative force is one for which work depends on the path taken, e.g. frictional force.

Boats use echo sounders. Pulses of sound waves are reflected by the sea bed and
detected by a sensitive microphone. The time between an echo sounder sending and
receiving a pulse is 0.005 s. The device calculates the depth of the sea, using the speed
of sound in sea water, which is 1500 m/s.
Use this information to calculate the depth of the sea. Show your working.

Answers

Answer: depth = 3.75 m

Explanation:

Taken the speed of the sound in sea to be V = 1500 m/s

The time between an echo sounder sending and receiving a pulse is 0.005 s. That is,

Total time T = 0.005

Formula for echo is:

V = 2X/T

Where X = distance covered

Substitute V and T into the formula

1500 = 2X/0.005

Cross multiply

7.5 = 2X

Make X the subject of formula

X = 7.5/2

X = 3.75 m

Therefore, the depth of the sea is 3.75 m

Calculate the wavelength of a nitrogen molecule moving at a speed of 523m/s.

Answers

Answer:

The de-Broglie wavelength of the nitrogen molecule is 0.0272 nm

Explanation:

The mass, m, of the nitrogen molecule, N₂ = 14.0076u = 28.0152 × 1.66 × 10⁻²⁷ kg

[tex]v_{rms}[/tex] of N₂ = 523 m/s

The de-Broglie wavelength is given as follows;

[tex]de-Broglie \, wavelength = \dfrac{h}{m\times v_{rms}}[/tex]

Where:

h = Planck's constant = 6.62607004 × 10⁻³⁴ m²·kg/s

Plugging in the values, we have;

[tex]de-Broglie \, wavelength = \dfrac{6.62607004 \times 10^{-34}}{28.0152 \times 1.66 \times 10^{-27}\times 523} = 2.72\times 10^{-11} \, m[/tex]

Hence, the de-Broglie wavelength of the nitrogen molecule = 0.0272 nm.

The temp of equal masses of three different liquids A,BandC are 12°C,19°Cand 28°Crespectively . The temp when A and B are mixed is 16°C, and when Band C are mixed is 23°C.The temp when A and C are mixed is

Answers

Answer:

19.1°C

Explanation:

If A and B mix to give 16°C, A has risen by 4°C and B has fallen by 3°C;

If B and C mix to give 23°C, B has risen by 3°C and C has fallen by 5°C;

This means the energy transfered to cause a change of 3°C in B causes a change of 4°C in A and 5°C in C;

We can use this as a ratio (4:5);

The temperature difference between A and C is 16°C;

we add the two parts of the ratio (4+5) to get 9 and divide the temperature difference to get 16/9;

Next we multiply this by one of the parts of the ratio, so with 4, you get 64/9;

This number is the proportional temperature change in A upon mixing;

We then add this to the original temperature of A to get the resultant temperature of the mix like so:

64/9 + 12 = 19.1111...

You can do this alternatively using the other part of the ratio;

We would multiply the 16/9 by the 5 instead of the 4 to get 80/9;

This number is the proportional change in temperature in C upon mixing

Then subtract this from this from the original temperature of C and you should get the same answer:

28 - 80/9 = 19.1111...

Do you think a population besides the moon jellies’ consumer population (sea turtles) and resource population (zooplankton) could have caused the moon jelly population to increase in size?

Answers

Answer:

I didn't quite understand your question, but the moon jelly population will increase if there are either more zooplankton or less sea turtles.

More zooplankton means more food => higher population

Less sea turtles means that the moon jelly will be lest often consumed => higher population

Answer: Yes because the Orca will start to eat the moon jellies

Explanation: When the Sea Turtles start to get very low on population the Moon jellies are next in line also the sea turtles eat the moon jellies and since they eat the moon jellies the sea turtle has a bit of that taste in them so they will taste alike to the sea turtles.

What is the velocity of the objects position vs time graph

Answers

Answer: In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing

An object with a mass of 120 kilograms is moving at a velocity of 30m/s what’s its momentum

Answers

Explanation:

Momentum = mass × velocity

p = mv

p = (120 kg) (30 m/s)

p = 3600 kg m/s

Given:

velocity, v = 30m/s

mass, m = 120kg

Therefore, momentum

p = mv

p = 120kg * 30m/s

p = 3600 kgm/s = [tex]3.6 * 10^3 kgms^{-1}[/tex]

What is a simple definition of momentum?

A property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity broadly.

What is momentum used for in physics?

Momentum is a vector quantity, it has both magnitude and direction. Since momentum has a direction, it can be used to predict the resulting direction and speed of motion of objects after they collide.

Light ray A moves from air to water. Part of ray A is reflected at the air-water boundary. Which arrow in the image is the reflected ray?
E
OA. B
OB.
С
OC.
D
OD. E

Answers

Answer:

A. B

Explanation:

The image has been attached.

Reflected ray refers to the ray of light which is reflected back after striking a surface that is non-permeable.

The ray of light which is reflected before the ray touches the surface is said to the incident ray.

According to the given image, ray B is the reflected ray. Ray B is reflected in the air after the ray A strikes at the surface of the water.

B

Explanation:

Since mirrors reflect things, when you shine light at a mirror, it will bounce off of the mirror, or reflect, and shine the opposite direction of where the original light is pointed. The answer would be B because light doesn't go through the mirror, or run along it.

Think of when you through a basketball on the ground. If you bounce it at an angle, it won't just come back to you in the same angle. It will keep bouncing at the same angle you through it. This is pretty much what describes the relationship between ray A and ray B.

Together, two students exert a force of 825 N in pushing a car a distance of 35 m.
How much work do the students do on the car?

Answers

Answer:

28875 Joule

Explanation:

W = F * d

W = 825*35 = 28875 J

The work done by the students in pushing a car at a distance of 35 meters would be 28875 Joules.

What is work done?

The total amount of energy transferred when a force is applied to move an object through some distance

The work done is the multiplication of applied force with displacement.

Work Done = Force * Displacement

As given in the problem Together, two students exert a force of 825 Newtons in pushing a car at a distance of 35 meters, then we have to  find out the work done by the students,

The force exerted by the students = 825 Newtons

The distance moved by car = 35 meters

work done by students = 825×25

                                       =28875 Joules

Thus, the work done by the students would be 28875 Joules.
