Answer:
The carbon atom has greater kinetic energy than a hydrogen atom.
Hope this helps! :)
Carbon atom has the greater kinetic energy.
What is meant by kinetic energy ?Kinetic energy is defined as the energy attained by a body by virtue of its motion.
Here,
The speed of the hydrogen atom and carbon atom are the same.
Kinetic energy of hydrogen atom, KEн = 1/2 m(н) v(н)²
Kinetic energy of carbon atom, KEс = 1/2 m(с) v(с)²
where m and v are mass and speed respectively.
Taking the ratio,
KEн/KEс = m(н)/m(с)
KEн/KEс = 2/12
KEн/KEс = 1/6
KEс = 6KEн
Therefore the kinetic energy of carbon atom is 6 times the kinetic energy of hydrogen atom.
Hence,
Carbon atom has the greater kinetic energy.

If the current in a wire which is placed perpendicular to a magnetic field increases the force on the wire
Answer:
The force on the wire increases
Explanation:
Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.
Given that the magnetic field and the wire are perpendicular, Ф = 90°
So, F = BILsin90° = BIL
Since B and L are constant, F ∝ I
So, if the current in the wire increases, the force on the wire also increases.
A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the frequency of the wave. (Unit = Hz)
Answer: 0.7
Explanation:
A fisherman sees 7 wave crests go by in 10 s, with wavelength (λ) ia 2.43 m has the frequency of the wave is 0.7 hertz.
What is a wave?A wave is defined as the propagation of distrubance from one place to another. It can carries energy when it propagates into the medium without the net movement of the particles.
It refers to the variations or flow of energy without the transfer of mass of particles or matter. The waves can be visible or invisible. Light and sound are travel in the form of waves.
In waves, the wavelength, frequency, wavespeed and time period can be identified. Frequency refers to the number of oscillations takes place per unit time. It is measured in hertz (Hz).
Wavelength(λ) defines the distance travelled by the wave in a particular time in one vibration. It is also defined as the spatial period of the wave. It can be obtained by taking ratio between wavespeed and frequency. The unit of wavelenght is meter(m).
Wavespeed of the wave equals the wavelength and frequency. It defines the distance travelled/ number of meter covered by given time. Wavespeed (v) = wavelength (λ) / frequency (f). Its unit is m/s.
Time period is inversely proportional to the frequency (f). The time taken by the wave to complete its one oscillation is called time period. Time period = 1 / f . Its unit is seconds (s).
From the given,
time = 10 secs
no of waves = 7
wavelength = 2.43 m
To obtain frequency from the givens, the formula for frequency is:
frequency = no.of.cycles of waves / time taken
= 7 / 10
f = 0.7 hertz.
Hence, the frequency of the wave is 0.7 Hz for 7 waves and given time 10 s.

Una botella vacía tiene una masa de 24.25g y de 86.55g completamente llena de agua, se vacia el agua y se llena nuevamente con 123.95g de solvente tetracloruro de carbono, ¿cual es la densidad del solvente?
Answer:
La densidad del tetracloruro de carbono es 1.990 gramos por centímetro cúbico.
Explanation:
La masa de agua contenida dentro de la botella es igual a la diferencia entre la masa pesada totalmente llena y la masa pesada totalmente vacía, es decir:
[tex]m_{w} = 86.55\,g-24.25\,g[/tex]
[tex]m_{w} = 62.3\,g[/tex]
Ahora, de acuerdo con la definición de densidad, la masa es directamente proporcional a la densidad, entonces, podemos calcular la densidad del solvente mediante la siguiente relación:
[tex]\frac{m_{x}}{m_{w}} = \frac{\rho_{x}}{\rho_{w}}[/tex] (1)
Donde:
[tex]m_{x}[/tex] - Masa del tetracloruro de carbono, en gramos.
[tex]m_{w}[/tex] - Masa del agua, en gramos.
[tex]\rho_{x}[/tex] - Densidad del tetracloruro de carbono, en gramos por centímetro cúbico.
[tex]\rho_{w}[/tex] - Densidad del agua, en gramos por centímetro cúbico.
Si sabemos que [tex]m_{x} = 123.95\,g[/tex], [tex]m_{w} = 62.3\,g[/tex] y [tex]\rho_{w} = 1\,\frac{g}{cm^{3}}[/tex], entonces la densidad del tetracloruro de carbono es:
[tex]\rho_{x} = \left(\frac{m_{x}}{m_{w}} \right)\cdot \rho_{w}[/tex]
[tex]\rho_{x} = 1.990\,\frac{g}{cm^{3}}[/tex]
La densidad del tetracloruro de carbono es 1.990 gramos por centímetro cúbico.

During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 130 N to the tire's rim. The mass of the wheel is 1.70 kg and, for the purpose of this problem, assume that all of this mass is concentrated on the outside radius of the wheel. The diameter of the wheel is 50.0 cm. A chain passes over a sprocket that has a diameter of 8.75 cm. In order for the wheel to have an angular acceleration of 3.50 rad/s2, what force, in Newtons, must be applied to the chain
Answer:
The force that must be applied to the chain in order for the chain to have the given acceleration is approximately 694.2 N
Explanation:
The given restive force, [tex]F_f[/tex] = 130 N
The mass of the wheel, m = 1.70 kg
The diameter of the wheel, D = 50.0 cm
∴ The radius of the wheel, R = 50.0 cm/2 = 25.0 cm = 0.25 m
The diameter of the sprocket over which the chain passes, d = 8.75 cm
The radius of the sprocket over which the chain passes, r = 8.75 cm/2 = 4.375 cm = 0.04375 m
The angular acceleration, α = 3.50 rad/s²
Torque, τ = I·α
Where;
I = The moment of inertia = m·R²·α
The net torque = The applied torque - The friction torque
Therefore, we get;
I × α = m × R² × α = F × r - [tex]F_f[/tex] × R
1.70 kg × (0.25 m)² × 3.50 rad/s² = F × 0.04375 m - 120 N × 0.25 m
F = (1.70 kg × (0.25 m)² × 3.50 rad/s² + 120 N × 0.25 m)/(0.04375 m) = 694.214286 N
The force that must be applied to the chain in order for the chain to have the given acceleration, F ≈ 694.2 N

Answer:
“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." So, This is connected to the biblical worldview and teaching in the sense that everyone is created with an equal opportunity or chance to live. No one is created literally equal or we would all look the same, talk the same, and think the same. Instead, we all have an opportunity at life and to live. Also, we all have the right to pursue happiness. Sin provides a certain happiness in our lives. It provides short-term happiness that corrupts us. In the “Declaration of Indepence”, sin is a pursuit of happiness, but also doing good is too. They meant that we should pursue what God says is good happiness. For instance, doing nice things to people and serving them. This makes me happy and every other human being that is not narcissistic or a robot. That happiness is joy and it does not come from our circumstances, but from the happiness in our hearts that shows a relationship with God.
You are rolling a ball in a veiled by kicking it. You get tired and stop kicking the ball. What happens to the potential energy of the ball.
Answer:
The potential energy of the ball becomes 0
Explanation:
When kicking the ball, and it moves up, the potential energy of the ball increases. When the ball descends downwards, the potential energy of the ball reduces.
This is so because potential energy increases as height increases and decreases when there is a reduction in height.
So, when you stop kicking the ball and you place the ball on the floor, the ball becomes static (motionless); hence, the potential energy becomes 0.

Please help! What's the answer to this question, A 5.6 nC electric charge is placed in an Electric Field and experiences a force of 7.4 μN. What is the magnitude of the Electric Field at that location?
Answer:
1321 N/C
Explanation:
From the question,
Electric Field (E) = Electric Force(F)/Electric Charge(q)
E = F/q............ Equation 1
Given: F = 7.4 μN = 7.4×10⁻⁶ N, q = 5.6 nC = 5.6×10⁻⁹ C
Substitute these value into equation 1
E = ( 7.4×10⁻⁶)/(5.6×10⁻⁹)
E = 1.321×10³ N/C
E = 1321 N/C
Hence the magnitude of the electric field at that location is 1321 N/C

Hence,
a = F/m
F = 6N applied in the direction of motion of the. Body
a = 6N / 4 kg
a = 1.5 m/s² in the direction of motion.
If the force is applied in the opposite direction of motion :
F = ma
a = F/m
a = 6 / 4
a = 1.5 m/s²
Simc efoece is applied in the opposite direction of motion :
We have a negative acceleration (deceleration) = - 1.5 m/s²
