5.0 kg, with a bullet of mass 0.1 kg. The target was mounted on
low-friction wheels and as the bullet struck the target, the target with
bullet embedded bullet sped off with a velocity of 6.0 ms.
Calculate the velocity of the bullet just before it hit the stationary
target.
Answer:
306 m/s
Explanation:
Law of conservation of momentum
m1v1 + m2v2 = (m1+m2)vf
m1 is the bullet's mass so it is 0.1 kg
v1 is what we're trying to solve
m2 is the target's mass so it is 5.0 kg
v2 is the targets velocity, and since it was stationary, its velocity is zero
vf is the velocity after the target is struck by the bullet, so it is 6.0 m/s
plugging in, we get
(0.1 kg)(v1) + (5.0 kg)(0 m/s) = (0.1 kg + 5.0 kg)(6.0 m/s)
(0.1)(v1) + 0 = 30.6
(0.1)(v1) = 30.6
v1 = 306 m/s
The initial velocity of the bullet can be determined from the total momentum of the system. The velocity of the bullet was 306 m/s.
What is momentum ?Momentum of a body is the product of its mass and velocity. For a collision, the momentum before and after collision will be the same for the colliding system.
Let m1 and m2 be the masses and u be the initial velocity and v is the final velocity.
then, m1 u1 + m2 u2 = m1 v1 + m2 v2.
Given m1 = 5 kg
m2 = 0.1 kg
The velocity of the combined mass v = 6 m/s.
The momentum of the target is zero since it was stationary.
(0.1 × u1) = (0.1 + 5)6 m/s
(0.1 × u1) = 30.6 m/s
then u1 = 30.6/0.1 = 306 m/s
Therefore, the velocity of the bullet before hitting was 306 m/s.

which of the following correctly describes the hierarchy of genetic material within a cell
Answer: D- Each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA
Explanation:
A macromolecule is a large molecule that is made of many smaller units. Chromosomes are macromolecules that contain all of the genetic information in a cell. Chromosomes are each made of two smaller units called chromatids. Chromatids are each made up of molecules of DNA. Therefore, the correct description of the hierarchy of genetic material in a cell is that each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA. The structures become more and more microscopic as one moves down the hierarchy.

Calculate the wavelength of a water wave with a speed of 3.0 m/s and frequency of
4.0 Hz.
Answer:
the answer is 12.0
The wavelength of the water wave is 0.75 meters.
What is wavelength?Wavelength is the distance between successive peaks or troughs of a wave. It is denoted by the symbol λ (lambda) and is measured in meters (m) or other units of length.
The wavelength of a wave determines its properties such as its energy, frequency, and speed. In general, waves with longer wavelengths have lower frequencies and travel at slower speeds, while waves with shorter wavelengths have higher frequencies and travel at faster speeds.
Here in the Question,
The relationship between the wavelength (λ), frequency (f), and wave speed (v) of a wave is given by the equation:
v = λf
We are given the speed of the water wave (v) as 3.0 m/s and the frequency (f) as 4.0 Hz.
Plugging these values into the equation, we get:
3.0 m/s = λ x 4.0 Hz
Rearranging the equation to solve for the wavelength, we get:
λ = v/f = 3.0 m/s ÷ 4.0 Hz = 0.75 m
λ = 0.75 m
Therefore, the wavelength of the water wave is 0.75 meters.

El carrusel de la feria del pueblo tiene una velocidad de 2 rpm. En un determinado instante se corta la corriente y como consecuencia del rozamiento, aparece una aceleración de frenado de 0,05 rad/s2.
Answer:
t = 4.19 s, θ = 0.437 rad
Explanation:
This is an exercise in rotational kinematics in this case we indicate the angular velocity and the angular acceleration, asking for the time and the angle it takes to stop.
w = w₀ + α t
w² = w₀² + 2 α θ
when the system stops the angular velocity is zero
0 = w₀- α t
0 = w₀² - 2 α θ
t = w₀ / α
tea = w₀² / 2 α
let's reduce the magnitudes to the SI system
w₀ = 2 rpm (2π rad / 1 rev) (1 min / 60s) = 0.209 rad / s
let's calculate
t = 0.209 / 0.05
t = 4.19 s
θ = 0.209 2/2 0.05
θ = 0.437 rad
The less mass an object has, the --- its gravitational f
Answer:
The less mass an object has, the less its gravitational [force.]
Explanation:
Newton's Law of Gravity states that [tex]F_G=\frac{Gm_1m_2}{r^{2}}[/tex]. The two m values are the objects' masses, G is the gravitational constant, and r is the distance between the objects' centers. Notice how the mass values are in the fraction's numerator? That means increasing the mass of one or both objects increases [tex]F_G[/tex]. That also implies the inverse; decreasing the mass of one or both objects decreases [tex]F_G[/tex]!

Kinetic energy increases as:
A. Mass increases and velocity decreases.
B. Mass decreases and velocity increases.
C. Both mass and velocity increase.
D. Both mass and velocity decrease.
Kinetic energy formula is: 1/2 mv^2
M = mass
V = Velocity
So as kinetic energy increases, mass increases and velocity increases because mass and velocity are directly proportional to each other.

Why is it important that your finger be wet if you intend to touch it briefly to a hot clothes iron to test its temperature. If your finger is wet, some of the heat transmitted to your finger will be given to the water which has a high specific heat capacity and also a larger latent heat of vaporization.
