Three circuits diagrams are shown. Which statement about the circuit diagram is accurate?

Answer:

The teddy bear did not stop at the same time as the car because of inertia.

Explanation:

The teddy bear did not stop at the same time as the car because of inertia.

Inertia is a resistance of an object to change its state of motion so if an object is moving it will continue the movement until a force act on it, and vice-versa if an object is at rest it will continue in that state until a force act on it.              

Hence, when the teddy bear was in the back seat and the car suddenly stops, the teddy kept moving forward because that was the direction of motion of the car (the teddy bear was moving forward with the car). The force of the brakes acts on the car but not on the teddy bear (not directly), that is why this force does not change the state of motion of the teddy bear.                     

Therefore, the teddy bear did not stop at the same time as the car because of inertia.

I hope it helps you!                    

Answer:

Load = 80 Newton

Explanation:

Given the following data:

Effort = 20 N

Load arm = 15 cm

Effort arm = 60 cm

Conversion:

100 cm = 1 meters

15 cm = 15/100 = 0.15 meters

60 cm = 60/100 = 0.6 meters

To calculate the load, we would use the expression;

Effort * effort arm = load * load arm

Substituting into the expression, we have;

20 * 0.6 = load * 0.15

12 = load * 0.15

Load = 12/0.15

Load = 80 Newton

Answer:

  (D)  4

Explanation:

The percentage error in each of the contributors to the calculation is 1%. The maximum error in the calculation is approximately the sum of the errors of each contributor, multiplied by the number of times it is a factor in the calculation.

  density = mass/volume

  density = mass/(π(radius^2)(length))

So, mass and length are each a factor once, and radius is a factor twice. Then the total percentage error is approximately 1% +1% +2×1% = 4%.

_____

If you look at the maximum and minimum density, you find they are ...

  {0.0611718, 0.0662668} g/(mm²·cm)

The ratio of the maximum value to the mean of these values is about 1.03998. So, the maximum is 3.998% higher than the "nominal" density.

The error is about 4%.

_____

Additional comment

If you work through the details of the math, you will see that the above-described sum of error percentages is just an approximation. If you need a more exact error estimate, it is best to work with the ranges of the numbers involved, and/or their distributions.

Using numbers with uniformly distributed errors will give different results than with normally distributed errors. When such distributions are involved, you need to carefully define what you mean by a maximum error. (By definition, normal distributions extend to infinity in both directions.) While the central limit theorem tends to apply, the actual shape of the error distribution may not be precisely normal.

[tex]F=G\cdot\dfrac{M \cdot m}{r^{2}}[/tex]

b.

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}}[/tex]

c.

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}} \approx 1.144 \times 10^{13} \ N[/tex]

d. The force of gravity acting on the satellite is approximately 1.144 × 10¹³ N

Explanation:

a. The formula for finding the force of gravity, F, acting object on an object is given as follows;

[tex]F=G\cdot\dfrac{M \cdot m}{r^{2}}[/tex]

Where;

F = The force acting between the Earth and the object

G = The gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²

M = The mass of the Earth = 5.97 × 10²⁴ kg

m = The mass of the object

r = The distance between the center of the Earth and the object

b. Finding the gravitational force, 'F', between the Earth and the scientific satellite, we have;

The given mass of the satellite, m = 1,300 kg

The distance between the center of the Earth and the center of the satellite,  r = The length of the radius of the Earth + The height of orbit of the satellite

The given height of orbit of the satellite, h = 200 km

∴ r = R + h = 6,378 km + 200 km = 6,578 m

Therefore, by plugging in the values, we get;

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}}[/tex]

c. Solving the above equation gives;

[tex]F=6.67430 \times 10^{-11} \dfrac{N \cdot m^2}{kg^2} \times \dfrac{5.97 \times 10^{24} \ kg \times 1,300 \ kg}{(6,578 \ m)^{2}} \approx 1.144 \times 10^{13} \ N[/tex]

The reproductive success of any species is the capability to produce their offspring per breeding lifetime or event.

Most of the species have to attract their partners by their physical capability and build up so that the mother can choose her partner in order to breed the best kind of off spring.

In the context, in case of deer, the size of the their antlers as well as behavior in herding is considered as the best chances for a successful reproduction to compete among the males and find their breeding mate.

Thus the answer is TRUE.

Consequently the statement is FALSE

Explanation:

The process of emission of electrons or photoelectric effect, was explained by Einstein, assuming that light behaves as formed by how many so-called photons and each one of them collides with an electron, therefore to start an electron the incident photon energy must be greater than the work function of the material.

            E =K + Ф

By mentioning the intensity we increase the number of photons but we do not increase their energy.

Answer:

B. Uranium 238.

Explanation:

Answer:

electron

Explanation:

The electron is the subatomic particle with the least mass. Therefore option A is correct.

Both protons and neutrons have significantly larger masses compared to electrons.

The mass of an electron is approximately 9.1 x 10^-31 kilograms, while the mass of a proton is about 1.67 x 10^-27 kilograms, and the mass of a neutron is also around 1.67 x 10^-27 kilograms.

It's important to note that the "atom" is not a subatomic particle but a structure composed of subatomic particles. An atom consists of a nucleus (composed of protons and neutrons) and electrons orbiting around the nucleus.

The mass of an atom depends on the number of protons, neutrons, and electrons it contains, so it can vary widely depending on the specific atom.

In summary, when comparing individual subatomic particles, the electron has the least mass.
