Answer:

They will crash with the force of 6,000N

Explanation:

Force is equal to mass time acceleration. When we multiply 200 kg, the mass, and 30 m/s2, the acceleration, the answer is 6,000.

Your answer would be C.

A step-up transformer is a transformer that raises voltage from main to secondary by having more secondary winding turns than primary winding turns.

Hope this helps; have a great day!

Answer:thermal energy

Explanation:

please mark this answer as brainliest

Statement C  is false. Doubling the mass doubles the acceleration is the wrong statement.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Force is defined as the product of mass and acceleration. Its unit is Newton.

Mathematically, the force is;

[tex]\rm F= ma[/tex]

If force is constant, the mass is inversely proportional to the acceleration. If the mass is double in that condition, acceleration is halved.

Doubling the mass doubles the acceleration is the wrong statement.

Hence, statement C  is false

Answer:

Aceleración media = 0.5 m/s²

Explanation:

Dados los siguientes datos;

Velocidad inicial = 15 m/s

Velocidad final = 20 m/s

Tiempo, t = 10 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.

Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;

[tex] Aceleracion = \frac{final \; velocidad - inicial \; velocidad}{tiempo}[/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Aceleracion = \frac{20 - 15}{10}[/tex]

[tex] Aceleracion = \frac{5}{10}[/tex]

Aceleracion = 0.5 m/s²

Por tanto, la aceleración media es igual a 0.5 metros por segundo al cuadrado.

Answer:

V = -0.4 m/s

Explanation:

Given that,

Mass of cart 1, m₁ = 3 kg

Speed of cart 1, v₁ = 2 m/s

Mass of cart 2, m₂ = 2 kg

Speed of cart 2, v₂ = -4 m/s (left)

aWe need to find the velocity of the carts after the collision if they stick together. Let the common speed be V. Using the law of conservation of momentum to find it such that,

[tex]m_1v_1+m_2v_2=(m_1+m_2)V\\\\V=\dfrac{m_1v_1+m_2v_2}{(m_1+m_2)}[/tex]

Put all the values,

[tex]V=\dfrac{3\times 2+2\times (-4)}{(3+2)}\\\\=-0.4\ m/s[/tex]

So, the velocity of the carts after the collision is equal to 0.4 m/s to the left.

Answer:

ΔL = 0.429 m

Explanation:

The expression for linear thermal expansion is

         ΔL = α L₀ ΔT

the coefficient of linear expansion of steel is 11 10⁻⁶ ºC⁻¹

the initial length of the bridge is L₀ = 1.30 10³ m and the temperature variation is ΔT = 30 ºC

calculate  

        ΔL = 11 10⁻⁶  1.30 10³  30

        ΔL = 4.29 10⁻¹ m

        ΔL = 0.429 m

Answer:

a) the number of particles increases

b) average distance between them should decrease

c) the number of particles decreases, the pressure must also decrease

Explanation:

a) When the girl pumps to increase the pressure inside the tire she introduces more particles. Therefore the number of particles increases

b) as the volume of the tire does not change and there are more particles, the average distance between them should decrease

c) When a hole is opened, some of the particles inside the tire come out, so as the number of particles decreases, the pressure must also decrease

Answer:

The locus of points where the electric field due to these lines is zero is;

Along the line between the lines closer to line#1 than line #2

Explanation:

The charges on the parallel lines #1 and #2 = Positive linear charge

The charge density on line #2, λ₂ = 2 × The charge density on line #1, λ₁

Therefore, we have;

λ₂ = 2 ×  λ₁

Electric field strength, E, is given as follows;

[tex]E = \dfrac{\lambda}{2\cdot \pi\cdot \epsilon_0\cdot d}[/tex]

Therefore;

[tex]E_1 = \dfrac{\lambda_1}{2\cdot \pi\cdot \epsilon_0\cdot d}[/tex]

[tex]E_2 = \dfrac{\lambda_2}{2\cdot \pi\cdot \epsilon_0\cdot d} = 2 \times\dfrac{\lambda_1}{2\cdot \pi\cdot \epsilon_0\cdot d}[/tex]

E₂ = 2·E₁

E₂/2 = E₁

E₂/(2·d) = E₁/d

The strength of the electric field at a given distance from line #2 is 2 times the strength of the electric field from line #1 at the same distance

Therefore the strength of the electric field will be the same at a point twice the distance from line #2 than from line #1 which is a point closer to line #1 than line #2.

The average speed of the inchworm 1 at 2 minutes in the given graph is determined as 0.025 m/s.

The average speed of an object is the rate of change of displacement of the object with time.

The average speed of the inchworm 1 at 2 minutes is calculated as follows;

v = D/t

v = 3 m/(2 min x 60 s)

v = 0.025 m/s

Thus, the average speed of the inchworm 1 at 2 minutes is 0.025 m/s.

C) Unscrew one light. If the other lights turn off, it's a series circuit.

Explanation:

THIS IS THE COMPLETE QUESTION BELOW;

A strand of 10 lights is plugged into an outlet. How can you determine if the lights are connected in series or parallel? A) Unscrew one light. If the other lights stay on, it's a series circuit. B) Unplug the strand. If the first light stays on, it's a series circuit. C) Unscrew one light. If the other lights turn off, it's a series circuit. D) Cut the strand in half. If the plugged in half stays on, it's a series circuit.

SERIES CIRCUIT

In this circuit, the components there are in the same path, the entire circuit has the same current, each of the components posses different voltage drop. Hence, failure of one components to work, there will be break in entire circuit then other components cease to work.

PARALLEL CIRCUIT

This circuit has equal voltage drop across all the components, any problem in a component will not has effect on other components.

Therefore, if one want to determine if a light connection is in series or in parallel, one of the light can be unplugged if others stop working it means it's series, if other works it's parallel.
