Which resistors in the circuit are connected in series?

Answer:

The type of energy is potential energy

Answer:

The maximum height reached by the ball is 0.212 meters (21.2 centimeters).

Explanation:

In this case, the ball receives a potential energy from deformed spring and reaches its maximum height at the expense of such energy. By Principle of Energy Conservation, we define the phenomenon on the ball by the following model:

[tex]U_{k,1}+U_{g,1} = U_{k,2}+U_{g,2}[/tex] (1)

Where:

[tex]U_{k,1}[/tex], [tex]U_{k,2}[/tex] - Initial and final elastic potential energies, measured in joules.

[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.

By definitions of elastic and gravitational potential energies, we expand and simplify the equation above as follows:

[tex]\frac{1}{2}\cdot k\cdot x^{2} = m\cdot g \cdot \Delta y[/tex] (2)

Where:

[tex]m[/tex] - Mass of the ball, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second. .

[tex]\Delta y[/tex] - Height reached by the ball, measured in meters.

[tex]k[/tex] - Spring constant, measured in newtons per meter.

[tex]x[/tex] - Spring deformation, measured in meters.

If we know that [tex]k = 65\,\frac{N}{m}[/tex], [tex]x = 0.08\,m[/tex], [tex]m = 0.1\,kg[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the maximum height reached by the ball is:

[tex]\Delta y = \frac{k\cdot x^{2}}{2\cdot m\cdot g}[/tex] (2)

[tex]\Delta y = \frac{\left(65\,\frac{N}{m} \right)\cdot \left(0.08\,m\right)^{2}}{2\cdot (0.1\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]

[tex]\Delta y = 0.212\,m[/tex]

The maximum height reached by the ball is 0.212 meters (21.2 centimeters).

Answer:

The answers B

Explanation:

Answer:

A. 24.5 m/s

B. 30.63 m

Explanation:

A. Determination of the vertical velocity of the apple.

Initial velocity (u) =?

Time (t) = 2.5 s

Acceleration due to gravity (g) = 9.8 m/s²

Vertical velocity (v) =?

v = u + gt

v = 0 + (9.8 × 2.5)

v = 0 + 24.5

v = 24.5 m/s

Thus, the vertical velocity of the apple is 24.5 m/s.

B. Determination of how far the apple has fallen.

Time (t) = 2.5 s

Acceleration due to gravity (g) = 9.8 m/s²

Height (h) =.?

h = ½gt²

h = ½ × 9.8 × 2.5²

h = 4.9 × 6.25

h = 30.63 m

Thus, the apple has fallen 30.63 m in 2.5 s.

Answer:

gamma rays

Explanation:

Answer:

D. Gamma Rays

Explanation:

Answer:

C) 9.4 m/s

Explanation:

[tex]m_1[/tex] = Mass of moving car = 1200 kg

[tex]u_1[/tex] = Initial velocity of moving car = 21.1 m/s

[tex]m_2[/tex] = Mass of stationary car = 1500 kg

[tex]u_2[/tex] = Initial velocity of stationary car = 0

v = Velocity of the combined cars

As the momentum in the system is conserved we have

[tex]m_1u_1+m_2u_2=(m_1+m_2)v\\\Rightarrow v=\dfrac{m_1u_1+m_2u_2}{m_1+m_2}\\\Rightarrow v=\dfrac{1200\times 21.1+1500\times0}{1200+1500}\\\Rightarrow v=9.378\approx 9.4\ \text{m/s}[/tex]

The velocity of the combined mass is 9.4 m/s.

They are because they don't know if viruses are alive and have a mind of its own or its just humans spreading it all around. Another reason is if they do find out they are alive or not they need to find solutions to kill them or to slow/stop the spreading.

The centripetal force on the  race car if its mass is 500 kg is 7,111.1N

The formula for calculating the centripetal force of the car is expressed as

[tex]C=\frac{mv^2}{r}[/tex]

m is the mass of the car

v is the velocity of the car

r is the radius of the circular path

Given the following parameters

m = 500kg

v = 80.0m/s

r = 450m

Substitute the given parameters into the formula as shown

[tex]F_c=\frac{500 \times 80^2}{450}\\F_c=\frac{500\times 6400}{450}\\ F_c=\frac{3,200,000}{450}\\F_c= 7,111.1N[/tex]

Hence the centripetal force on the  race car if its mass is 500 kg is 7,111.1N

Answer:

1111 m

Explanation:

The following data were obtained from the question:

Height (h) = 500 m

Horizontal velocity (u) = 110 m/s

Horizontal distance (s) =?

Next we shall determine the time taken for the pallet to get to the target. This can be obtained as follow:

Height (h) = 500 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =?

h = ½gt²

500 = ½ × 9.8 × t²

500 = 4.9 × t²

Divide both side by 4.9

t² = 500/4.9

Take the square root of both side.

t = √(500/4.9)

t = 10.1 s

Finally, we shall determine how far the pallet needs to be dropped in order to get to the target. This can be obtained as follow:

Horizontal velocity (u) = 110 m/s

Time (t) = 10.1 s

Horizontal distance (s) =?

s = ut

s = 110 × 10.1

s = 1111 m

Thus, the pallet must be dropped at a distance of 1111 m from the plane in order to get the target.

Fuerza F = 600N

diámetro d1- 6cm am = 0.06m

A1 = πd1 ^ 2/4 = 3.142 * 0.06 ^ 2/4

= 0,002 m ^ 2

Carga L = 350 kg a newton = 350 * 10 = 3500N

A2 =?

Segundo paso:

sabemos que la presión aplicada a un extremo para levantar una carga en el otro extremo se expresa matemáticamente como

F1 / A1 = F2 / A

sustituir

600 / 0.002 = 3500 / A

cruzar multiplicar

A2 = 0.002 * 3500/600

A2 = 9.89 / 600

A2 = 0.02

sabemos que área = πd ^ 2/4

0.02 = πd2 ^ 2/4

0.02 = 3.142 * d2 ^ 2/4

0.02 * 4 / 3.142 = d2 ^ 2

0.025 = d ^ 2

d = √0.025

d = 0,15 m

Answer:

40g

Explanation:

Mass = density x volume

= 2 x 20

= 40g

Answer:

m =  V × ρ

=  20 milliliter × 2 gram/cubic meter

=  2.0E-5 cubic meter × 2 gram/cubic meter

=  4.0E-5 gram

=  4.0E-8 kilogram

Explanation:

The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.

ρ =    

m  

V

           where:

ρ is the density

m is the mass

V is the volume

The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of mass  volume. Note that density is also affected by pressure and temperature.

Latent heat of vaporization refers to changes of state from liquid to gas or gas to liquid. Hence, option (a) is correct.

In thermodynamics, latent heat is the heat or energy that is absorbed or released when a substance undergoes a phase change. A liquid to solid transition or a gas to liquid transition are both possible. Enthalpy, another heat attribute, is connected to latent heat.

When matter breaks down and transitions from a fluid to a gas at a constant temperature, this is known as latent heat of vaporization.

The heat of water vaporization is the highest known temperature. The heat of vaporization is defined as the amount of heat necessary to turn 1 g of a fluid into a fume without causing the fluid's temperature to change.
