Answer: V' = 1.514m/s

Explanation: Given the Impulse-Momentum Theorum, this is a description of an INELASTIC Collision. When you hug, you stick, making it inelastic.


Formula: m1xV1+m2xV2= pTotal, or total momentum

m1=60kg

V1=1.5m/s

m2=45kg

V2=2.2m/s

so (60)(1.5)+(45)(2.2)=159 kgm/s

To find the Resultant velocity of the lover(s) - plural (signalling inelastic)

you would take the sum of the m1+m2, which is 105kg-> then create the equation 159/105, which is the total momentum divided by the total mass, which would equate to the resultant velocity of an inelastic collision.

Hope this helped.

Answer:

receptors

Explanation:

In this case, your skin and brain act as receptors in maintaining homeostasis. These receptors are monitors in different parts of an organism's body that are there to detect specific changes that occur and activate very specific responses in order to counteract these changes and maintain a very stable system. This is exactly, what your skin and brain are doing in this scenario, they detect the change in temperature and counteract its effects through sweat which ultimately causes the opposite effect and maintains equilibrium in your body.

The net force has a magnitude of C, 5.0 N.

To find the net force, add the two forces vectorially. Break down each force into its x and y components:

F₁ = (2.01 N)î + (4.03 N)ĵ

F₂ = (3.01 N)î + (6.01 N)ĵ

To find the net force, add the components:

F_net = F₁ + F₂ = (2.01 N + 3.01 N)î + (4.03 N + 6.01 N)ĵ

F_net = 5.02î + 10.04ĵ

The magnitude of the net force is given by:

|F_net| = √((5.02 N)² + (10.04 N)²)

|F_net| = √(25.2004 N²)

|F_net| = 5.02 N (rounded to two decimal places)

Therefore, the magnitude of the net force is 5.0 N.

The initial mechanical energy of the roller coaster consists of its potential energy (due to its height above the ground) and its kinetic energy (due to its initial speed):

Ei = mgh + 1/2 mv^2

The final mechanical energy of the roller coaster consists of its potential energy:

Ef = mgh' + 1/2 mv'^2

Explanation:

Answer:

False the universe has not always existed the way it does now.

Explanation:

Answer: False

Explanation: The Universe continues to expand even today, growing at a rate of 6.5 light-years in all directions per year as time goes on.

Option C) The experiment in which the speed of the object was changed

is only statement that doesn't satisfy the given data as shown below:

The above statement can be verified using the calculation:

Formula for centripetal force(F) = \(\frac{mv^2}{r}\)

where m is mass of object , v is speed of object and r is radius of the circular motion.

For option A) when only mass of object is changed and rest all are same.

so F = k*m where k = \(\frac{v^2}{r}\) as both are constant

=> \(\frac{F_1}{F_2}\) = 4.04/8.08 = 0.5

and \(\frac{m_1}{m_2}\) = 0.1/0.2 =0.5

so \(\frac{F_1}{F_2} = \frac{m_1}{m_2}\)

similary \(\frac{F_2}{F_3} = \frac{m_2}{m_3}\) and hence data is correct for option A)

For option B) when only radius of object is changed and rest all are

same.

so F = k/r where k = \(m*v^2\) as both are constant

=> \(\frac{F_1}{F_2}\) = 4.04/8.08 = 0.5

and \(\frac{r_2}{r_1}\) = 0.3/0.6 =0.5

so \(\frac{F_1}{F_2} = \frac{r_2}{r_1}\)

so both are same , similary \(\frac{F_2}{F_3} = \frac{r_3}{r_2}\) and hence data is correct for option B

For option C) when only speed of object is changed and rest all are

same.

so F = k*\(v^2\) where k = \(\frac{m}{r}\) as both are constant

=> \(\frac{F_1}{F_2}\) = 4.04/9.09 = 0.44444

and \(\frac{v_1^2}{v_2^2}\) = 4.08/9.181 =0.44439

so ,\(\frac{F_1}{F_2}\) ≠ \(\frac{v_1^2}{v_2^2}\)

and hence data is not correct for option C

The angular velocity of link BD is 2.89 rad/s and the angular acceleration is 0 rad/s².

The expression for angular acceleration can be calculated by applying the vector method.

Here, the vector method of angular velocity will be applied to get the expression for angular velocity ω2 and angular acceleration α2 as follows:

Step 1:Velocity of the collar relative to B and velocity of point A of the link AB and collar can be written as VB = VA + AB X ω1

Here, AB is perpendicular to the plane of rotation, and the velocity of A relative to the collar is ω1 * AB.

Therefore, AB X ω1 = 0 as AB is parallel to AB. Thus, VB = VA.

Then, the velocity of point B can be given as:

VB = BD X ω2Hence, BD X ω2 = VA, we get: ω2 = VA / BD

Step 2: Acceleration of point A relative to collar: AB X α1 = 0 (AB parallel to the plane of rotation)

AA = AB X ω1 X ω1=0

Acceleration of point A relative to C: AC X α1 = AC X 10α2=0

Since, AC=AB=1m

α2=0

Acceleration of collar C relative to point B: BD X α2=VA

Here, α2 = 0, and VB = VA = 5m/s.

Hence:BD * 0 = 5m/sω2 = VA / BD= 5 / (1.732 x 1)=2.89 rad/s

Thus, the angular velocity of link BD is 2.89 rad/s and the angular acceleration is 0 rad/s².

group of multiple universes

these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them.

The angle of incidence of the light ray is approximately 24.4°.

When a light ray crosses from one medium to another, it bends due to a change in its speed. This bending is described by Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the speeds of light in the two media.

In this case, the light ray crosses from water into glass, so we know that the speed of light in glass is slower than in water. The angle of incidence is the angle between the incident ray and the normal to the interface, while the angle of refraction is the angle between the refracted ray and the normal.

Since we are given the angle of refraction (30°), we can use Snell's law to find the angle of incidence. Letting \(n_1\) and \(n_2\) be the indices of refraction of water and glass respectively, we have:

\($\frac{\sin(\theta_{i})}{\sin(30°)}=\frac{n_2}{n_1}$\)

We can look up the indices of refraction of water and glass and find that \(n_1\) = 1.33 and \(n_2\) = 1.5. Solving for the angle of incidence, we get:

\($\sin(\theta_{i})=\sin(30°)\times\frac{n_1}{n_2}=0.414$\)

Taking the inverse sine of both sides, we get:

angle of incidence = 24.4°

Ancient astronomers observed planets exhibiting noticeable movement against the background of fixed stars, distinguishing them as wandering objects in the night sky.

Unlike the fixed stars, which maintained a relatively stable position in the night sky, planets displayed distinct motion over time when observed by ancient astronomers. While stars appeared to maintain their positions relative to each other, planets exhibited a wandering or meandering path against the backdrop of the fixed stars. This irregular motion set planets apart, capturing the attention of ancient astronomers and prompting them to recognize them as distinct celestial entities. The movement of planets was often retrograde, appearing to temporarily reverse their usual eastward motion relative to the stars before resuming their regular path. This unique behavior of planets distinguished them from the fixed stars and piqued the curiosity of early astronomers.
