A cart of weight 20 N is accelerated across a level surface at 0.15 m/s?. What net force acts on
the wagon?

Answer:

potential

Explanation:

Answer:

Accuracy

Explanation:

Accuracy means making measurements that are close to the value precision means making measurement that are close in value to eachother but not necessarily close to the true value.

I hope this helps! If not sorry.

Considering the definitipn of current, voltage, power, and Ohm's law,

The flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.

The conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.

Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.

This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.

The resistance that is measured in ohms.

Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.

Mathematically, Watt's law is expressed:

[tex]I=\frac{V}{R}[/tex]

So if you want to find resistance, the expression for its calculation is:

[tex]R=\frac{V}{I}[/tex]

In this case, you know:

Replacing:

[tex]R=\frac{5.26 V}{0.41 A}[/tex]

Solving:

R= 12.8 ohms

Habiba is right. The resistance is 12.8 ohms.

The above answer is correct too, keep busy

Answer:

3 times as much

Explanation:

half as much would be 12%, as much would be 24%, and two times as much would be 48%.

3 times as much is 72, which is about 74%

Answer:

N = N0 e^-kt          calling k the decay constant

70 = N0 e^-2 kt

35 = N0 e^-15 k

2 = e^(-2 + 15) k

.693 = 13 k

k = .0533

N0 = N e^kt

N0 = 70 e^(.0533 * 2) = 77.87

8.75 = 77.87 e^-(.0533 t)

ln .1124 = -.0533 t

t = -ln .1124 / .0533 = 41 yr

Answer:

62.9%. The molar mass of sodium carbonate is 106 grams per mole. Each water molecule adds another 18.0 grams per mole.

Force is a vector quantity hence it can be resolved into a vertical and a horizontal components.

1) The horizontal component of the applied force is given by;

Fnet = F cos θ

Fnet = 70.0N × cos (45.0)

Fnet = 49.5 N

2) The horizontal component of the frictional force is;

F = -Ff + mgsinθ

F = applied force

Ff =mgsinθ - F

Ff = (11 × 10 × sin 45) - 49.5

Ff = 28.3 N

Horizontal component of Ff

28.3 N cos 45 = 19.9 N

3) The applied force is given by;

F = 11 Kg ×  1.00m/s^2 = 11.0 N

I've heard of many different names of isotopes of carbon, and they're Carbon-14, Deuterium, Hydrogen-1, Oxygen-18, boron-11, Nitrogen-14, and Neon-20.

Answer:

The distribution of charge is the result of electron movement. Since conductors allow for electrons to be transported from particle to particle, a charged object will always distribute its charge until the overall repulsive forces between excess electrons is minimized.

Answer:

This is simply the movement and transportation of electrons

80 kg weighs 80 kg x 9.8 m/s2 = 784 kg m/s2, or 784 Newtons. The surface gravity of Mercury is 0.39 that of Earth's (table 10-1), so 80 kg weighs 784 N x 0.39 = 306 N.

Answer:

This downward force and acceleration results in a downward displacement from the position that the object would be if there were no gravity. The force of gravity does not affect the horizontal component of motion; a projectile maintains a constant horizontal velocity since there are no horizontal forces acting upon it

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.

A concentration refers to a subject or study within a specific major. As part of the degree coursework, concentration classes count toward your major requirements as well.

Vectors need direction and magnitude to exist, otherwise, it becomes scalars that do not require direction to be expressed.

eg - Velocity is a vector as it needs direction, but speed is scalar and does not need direction

Answer:

a. All quantities in physics are not vectors. b. A vector may have either magnitude or direction. c. The vector's length should be proportional to its magnitude. d. Two vectors can be added only if they have the same direction.
