The speed of 5 kg ball is 10.2 m/s

Given data:

The mass of cart 1 is m₁=3 kg.

The speed of cart 1 moving east is v₁=17 m/s.

The mass of other cart is m₂=5 kg.

Since the carts stick together, and comes to rest their final velocity is zero, i.e., v=0.

Applying the conservation of momentum between the carts as,

Here, v₂ is the speed of 5kg cart. Since the cart 2 moving in west direction therefore v₂=-v₂.

Substitute all the values in above equation,

Thus, the speed of 5 kg ball is 10.2 m/s.

Final answer: 10.2 m/s

Answer:

P V = N R T

P1 V1 = P2 V2      assuming N, R, and T remain constant

V1 = (P2 / P1) V2

V1 = (2 kPa / 4 k Pa) 3.5 m3

V1 = 3.5 m^3 / 2 = 1.75 m^3

Answer:

Yes, the value of g affected by the radius.

Explanation:

The formula for the force of gravity of 2 objects is

\(F_{gravity} = G\frac{m_{1}m_{2}}{r^2}\), where m1 and m2 are the masses of the 2 objects, r is the radius, and G is the gravitational constant, which is approximately \(6.67 \cdot 10^{-11}\).

Explanation:

True, due to the protective nature of the ozone layer and the absorption of UV radiation, conducting ultraviolet astronomy from space is necessary to gather accurate and detailed data about celestial objects and phenomena emitting UV light.

The ozone layer plays a crucial role in protecting the Earth's surface from harmful ultraviolet (UV) radiation. It absorbs a significant portion of the Sun's UV rays, preventing them from reaching the surface and potentially causing damage to living organisms.

As a result, to observe and study ultraviolet astronomy, which involves the detection and analysis of celestial objects and phenomena emitting UV radiation, observations must be conducted from space. By observing from space, astronomers can bypass the Earth's atmosphere, including the ozone layer, and directly capture the UV light from celestial sources.

UV astronomy satellites and telescopes, such as the Hubble Space Telescope and the International Ultraviolet Explorer (IUE), have been specifically designed and deployed to conduct observations in the ultraviolet spectrum. These instruments are situated above the Earth's atmosphere, enabling them to capture and analyze UV radiation without interference from atmospheric absorption.

The acceleration of the object when it will start falling from the height above the earth is ( 1/9 ) gₓ.

Acceleration due to gravity from the height = gₙ

Acceleration due to gravity on earth = gₓ

Distance between the core of earth and the point at a height above earth = h

Radius of the earth = rₓ

Now, for h = rₓ

= Using the gravitational formula

= gₙ = gₓ ( rₓ / (rₓ + rₓ))²

Answer:

F = ma - T sinθ

Explanation:

The equation of centrifugal force on the bob is F = ma - T sinθ.

A conical pendulum consists of a weight (or bob) fixed on the end of a string or rod suspended from a pivot. Its construction is similar to an ordinary pendulum; however, instead of swinging back and forth, the bob of a conical pendulum moves at a constant speed in a circle with the string (or rod) tracing out a cone.

The centrifugal force (F) is the net horizontal outward force on the bob of the pendulum. By breaking T into its components, we get T sinθ acting horizontally in the +x-direction.

To calculate the new volume of the balloon, we can use the formula:
V2 = V1 * (T2/T1)
where V1 is the initial volume of the balloon, T1 is the initial temperature, T2 is the final temperature, and V2 is the final volume.
Substituting the given values, we get:
V2 = 3.02 * (316.6/295.7)
V2 = 3.23 L (rounded to two decimal places)
Therefore, the new volume of the balloon is 3.23 L when it is heated to 43.6°C.

To calculate the new volume of the balloon, we can use Charles's Law, which states that the volume of a gas is directly proportional to its temperature when the pressure and amount of gas are constant. The formula for Charles's Law is:
V1 / T1 = V2 / T2
Where V1 is the initial volume (3.02 L), T1 is the initial temperature (22.7°C), V2 is the final volume, and T2 is the final temperature (43.6°C). First, convert the temperatures to Kelvin by adding 273.15:
T1 = 22.7°C + 273.15 = 295.85 K
T2 = 43.6°C + 273.15 = 316.75 K

Now plug the values into the formula:
(3.02 L) / (295.85 K) = V2 / (316.75 K)
To find V2, multiply both sides by 316.75 K:
V2 = (3.02 L) * (316.75 K) / (295.85 K)
V2 ≈ 3.24 L
The new volume of the balloon when heated to 43.6°C is approximately 3.24 L.

Select all the correct answers.

Who are two target audiences for the passage "Gluten Free"?

a) people interested in weight loss.

b) doctors who treat people with celiac disease.

c) people who educate others about health decisions.

d) people with gluten sensitivity.

e) people considering making a lifestyle change

Passage: Gluten Free

Many people consider products made from whole grains, such as bread and cereal, to be delicious as well as nutritious. However, gluten allergies are on the rise, and many people can

no longer eat these types of food. Gluten is a type of protein found in wheat, rye, and barley. This substance can also be found in sauces, soups, and salad dressings. The widespread

use of gluten can make it difficult to know which foods are safe for people with gluten allergies. Allergic responses to gluten can range from stomach aches to acne, and they can even cause more serious health issues in some individuals. A serious allergy to gluten is called celiac disease. In the United States, millions of people suffer from this disorder. Celiac is a digestive

disease that hinders people from properly absorbing nutrients from food. This disease can lead to various health issues, so people with these allergies need to be careful about the food.

Eating in restaurants can be difficult for people with celiac disease. However, there are things people can do to ensure that their food is safe. For example, calling ahead to see if the

restaurant has a gluten-free menu is a start. Even when at the restaurant, people should not be afraid to ask the server or they eat.

d) people with gluten sensitivity

e) people considering making a lifestyle change

Explanation:

Gluten can be defined as protein that is found is starchy grains such as wheat, rye, barley e.t.c.

One of the main or major functions of gluten is when wheat is used to make dough for bread, pasta, pizza e.t.c , the stretching or elasticity of the dough is due to the presence of gluten in the dough.

Despite these desirable quality, it has been discovered the people are allergic to gluten and these days we have gluten free foods or restaurant that served gluten free foods such as bakes, cakes e.t.c.

One of the allergies of gluten is called Celiac disease. Celiac disease is an allergy that makes it difficult for the human body to be able to digest gluten as well absorbing other food nutrients. This results in symptoms such as flatulence, bloating, diarrhea, vomiting, stomach pain, weight loss e.t.c.

We have been educated in the passage that although it quite difficult for people with Celiac disease to eat at restaurants, but in other to effectively manage the allergy, when you want to eat out, it is best to call the restaurant first to verify if they have gluten free meals or ask the waiter if they have gluten free meals.

The energy an object has due to its motion is called kinetic energy

Explanation:

Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass.

Answer:

kinetic energy

Explanation:

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

If you float the ball at equilibrium in oil, the ball will have more than half of its volume submerged in the oil.

When an object floats, it moves the same volume of fluid as the object itself weighs. The displaced fluid exerts an upward buoyant force on the object, balancing its weight and allowing it to float at equilibrium.

Since oil is less dense than water, it provides less buoyant force per unit volume compared to water. To achieve equilibrium in oil, the ball would need to displace a greater volume of oil to counteract its weight. As a result, more than half of the ball's volume would need to be submerged in the oil for it to float at equilibrium.
