Answer:

0.5

Explanation:

Given parameters:

Weight of object  = 300N

Force of friction = 150N

Unknown:

Coefficient of friction = ?

Solution:

Frictional force is a force that resists the motion of a body.

        It is mathematically expressed as;

                  frictional force  =  uN

Where u is the coefficient of friction

           N = Normal force = weight of the object

Now input the parameters and find u;

             150 = u x 300

                 u = [tex]\frac{150}{300}[/tex]   = 0.5

The coefficient of friction here is 0.5

Answer:

16 m/s

Explanation:

from the formula: a = velocity/time

you calculate the velocity in both cases (when time is 5 sec and 6 sec) by using the formula: velocity = a x time

v (5 sec) =24 m/s

v (6 sec) = - 8 m/s

then : add v (5 sec) to v (6 sec) and the result is 16 m/s

Answer: Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.

Explanation:

The function of Consumer Product Safety Commission is to make sure that the products which are used by consumers are safe and also make sure that companies meet the required and acceptable safety standards. The products that are seen to be harmful to the health of the consumers are banned.

Regarding the question above, CPSC would perform studies when other soap and detergent companies have already conducted research on the same products because the studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.

Answer:

Tests performed by the CPSC follow established scientific methods, but those performed by soap companies do not.

Answer:

D. The rest of the bulbs stop shining and shut off.

Explanation:

When one bulb  in a series circuit  burns, out, the rest of the bulbs stop shining and shut off.​ Option D is correct.

What is an electric bulb?

An electric bulb is a gadget that uses electricity to create visible light. It is the most popular type of artificial lighting and is necessary for modern society.

The light bulb is connected to a switch in a parallel configuration. The switch is open, which means there will be a lot of resistance and no current will flow via this route.

Across the parallel connection, the battery would create the same potential difference. Because the current would not go via the open switch, it would instead flow through the light bulb, causing it to illuminate.

When one bulb  in a series circuit  burns, out, the rest of the bulbs stop shining and shut off.​

Hence, option D is correct.

Unit for Acceleration is m/s² or ms raised to -2

Answer:

Normal, Gravity, Friction, and Air Resistance.

Explanation:

When a moving car skid to stop and its wheels are locked across, then the following forces will be applied on the car:

Normal force: It will act counter to gravity that pushes an object against a surface and acts perpendicular to the contact surface.

Gravity: Gravity force acts in each and every object having mass and it can not be avoidable. So, the gravity force will also apply to the car and attract it to the earth's surface.

Friction: Friction is a force that acts opposite to the motion and stops or slows motion. Friction will be applied to the car that will oppose the motion of the car and stop it.

Air resistance: air resistance is defined as the forces exerted by air that acts opposite to the relative motion of an object. Air resistance will also be applied to the car when it will skid to stop as we are always surrounded by the air.

Hence, the correct answers are "Normal, Gravity, Friction, and Air Resistance."

Answer:

q + d = 50

25q + 10d = 980

Explanation:

The equation that can be employed to determine the number of quarters(q), as well as, dimes(d) that Yodelin has would be:

q + d = 50...(1)

25q + 10d = 980...(2)

Multiplying (1) by 25

25q + 25d = 1250 ...(3)

25q + 10d = 980...(4)

subtracting (4) from (3)

15d = 270

d = 18

q = 50 - 18

    = 32

The system of the equations could be

q + d = 50

25q + 10d = 980

Since Yodelin has fifty quarters and dimes. Their total value is $9.80.

So here the equations be

q + d = 50...(1)

25q + 10d = 980...(2)

Now we have to Multiplying (1) by 25

So,

25q + 25d = 1250 ...(3)

25q + 10d = 980...(4)

Now

subtracting (4) from (3)

15d = 270

d = 18

So,

q = 50 - 18

   = 32

Explanation:

Force = Mass x Acceleration

Answer:

[tex]\boxed {\tt 1,200 \ Newtons }[/tex]

Explanation:

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass is 300 kilograms.

The acceleration is 4 meters per second squared.

[tex]m= 300 \ kg\\a= 4 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 300 \ kg * 4 \ m/s^2[/tex]

Multiply.

[tex]F= 1200 \ kg * m/s^2[/tex]

1 Newton is equal to 1 kilograms meters per second squared, so our current answer of 1200 kg m/s² is equal to 1200 Newtons.

[tex]F= 1200 \ N[/tex]

The force needed is 1,200 Newtons.

24 i think

Answer:

B. 24

Explanation:

There are 24 atoms in one molecule of C6 H12 06. This chemical compound is made up of 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen. We find the number of atoms by adding these numbers up. We than get:

6 + 12 + 6 = 12 + 12 = 24

Therefore, there are 24 atoms in the following chemical formula.

Answer:

The velocity vBW of the boat relative to the water is 4.0 m/s, directed perpendicular to the current, as in Figure 3.18.

Explanation:

The boat is perpendicular to the shore. Then the net velocity of the boat with respect to river is 5 m/s. The observer feels like the boat is moving slower than they appear actually.

Relative velocity is velocity of an object measured with respect to other object which can be of stationary or moving with a speed. Thus speed relative to another object is called the relative velocity.

The relative velocity is what's the speed for an observer but it differs from actual velocity. Sometimes it may slower or faster depending on the object with which a we are relating the speed.

Given that the speed of the boat = 4 m/s

speed of river = 3 m/s.

Both are perpendicular and the net velocity of the boat is :

r = √(3² + 4²) = 5 m/s.

Hence, the velocity of the boat relative to the shore will be 5 m/s.

The velocity of the gold puck after the collision is equal to (2i - j) m/s. Therefore, option (A) is correct.

The rate at which a displacement of the body changes in relation to time is called its velocity. Velocity is a vector parameter with both magnitude and direction. S.I. unit of velocity can be represented as meter/second.

Given, the mass of the gold puck, m = 12 kg

The velocity of the gold puck before the collision, u =  5i – 4j m/s.

The mass of the stationary blue puck, M = 18 kg.

The velocity of it after the collision, V = 2i – 2j m/s.

We have to determine the velocity of the gold puck after the collision:

The total momentum of the system before the collision is equal to the total momentum of the system after the collision.

mu + M ×0 = mv + MV

v = u - MV/m

v  = (5i – 4j) m/s  - (2i – 2j)m/s × 18/12

v  = (5i – 4j) m/s - (3i - 3j)

v = (2i - j) m/s.

Therefore, the velocity of the gold puck is (2i - j) m/s after the collision.

Here are the options.

A. energy is continuously created.

B. energy is continuously destroyed.

C. energy exists in a field.

D. all of these

The correct option is C.

Energy exists in a field.

Explanation:

Energy is the ability to do work or the property i.e force or power that is moved to an object so that it can perform work.

Energy exists in a field because a field is a region in which each area is affected by a force or power on an object . For example a paper clip placed on a magnetic field require a force or power to be able to attract or repel magnets.

An electric field surronds an electric charge when another particle is around it, it uses energy to either attract or repel the object e.t.c.

Therefore energy exists in field.
