its resistance when it is operated at the correct
voltage?​

Answers

Answer 1

Answer:

The resistance of the lamp is 4Ω.

Answer and Explanation:

Using a = F/m, we get:

Acceleration for Road A = 480/62 = ~7.74 m/s^2

Acceleration for Road B = 240/62 = ~3.87 m/s^2

Acceleration for Road C = 600/62 = ~9.68 m/s^2

If the net force becomes higher than 600N and the mass stays constant, the acceleration will increase proportionally to how much the force increases and the acceleration will be greater than the acceleration when the force is 600N.

A motorcyclist drives around a bend with a 20 m radius, with a constant velocity of 3 m/s. The motorcyclist and the motorcycle have a combined mass of 50 kg. What is the motorcyclist’s centripetal acceleration?

Answers

Answer:

[tex]a=0.45\ m/s^2[/tex]

Explanation:

Given that,

The radius of a bend, r = 20 m

Velocity of motorcyclist, v = 3 m/s

The combined mass of motorcyclist and the motorcycle is 50 kg

We need to find the motorcyclist’s centripetal acceleration. The formula used to find the centripetal acceleration is given by :

[tex]a=\dfrac{v^2}{r}\\\\a=\dfrac{(3)^2}{20}\\\\a=0.45\ m/s^2[/tex]

So, the acceleration of the motorcyclist is [tex]0.45\ m/s^2[/tex].

What is the end product of mitosis?

B. Two identical nuclei
C. One complete zygote
D. A cell with one set of chromosomes

Answers

Answer:

It is B

Explanation:

I did the test

From the given options, the end product of mitosis is Two identical nuclei (option b)

Mitosis is a fundamental cellular process that occurs in somatic (non-reproductive) cells, aiming to create two genetically identical daughter cells from one parent cell. It consists of several stages: prophase, metaphase, anaphase, and telophase.

During prophase, the chromatin (a combination of DNA and proteins) condenses into visible chromosomes, and the nuclear membrane disintegrates. In the subsequent stage, metaphase, the chromosomes align at the cell's equator, ensuring each daughter cell receives an equal number of chromosomes.

Next comes anaphase, where the paired chromosomes are pulled apart and move towards opposite poles of the cell. The final phase, telophase, involves the formation of two separate nuclei around the separated chromosomes.

At the end of mitosis, the single parent cell has divided into two genetically identical daughter cells, each containing a complete set of chromosomes. These daughter cells are fully functional and capable of carrying out their specific tasks within the organism.

So, the correct Answer: B. Two identical nuclei.

Kinetic energy of 110 j and velocity of 70 m/s what is the mass

Answers

Answer:

Explanation:

Explanation in pics:

The formula for kinetic energy is KE = 1/2mv². So now the question asks for the mass, not KE. So we need to rearrange the formula so that we are calculating the mass. So, the formula for mass is m=KE/(1/2v²). Now we just substitute the values into the formula. Then just follow what it shows in the pic

Water

Explanation:

Answer:

So, water has a specific heat of exactly 1.00 calorie per gram per °C. Because one calorie is equal to 4.18 J, it takes 4.18 J to raise the temperature of one gram of water by 1°C. In joules, water's specific heat is 4.18 J per gram per °C.

You place a drop of blue food coloring in a cup of cold water and another drop of food coloring in a cup of hot water. Which observation is correct and why? A The food coloring in the hot water will spread more slowly than in the cold water because water molecules move more slowly when hot. B The food coloring in the hot water will spread more quickly than in the cold water because water molecules move more quickly when hot. C The food coloring in the cold water will spread more quickly than in the hot water because water molecules move more quickly when cold. D The food coloring in the cold water will spread at the same rate at the food coloring in the hot water because water molecules at any temperature move at the same rate.

Answers

Answer:

B food coloring will move quicker in hot water because the molecules move faster when they are hot

Explanation:

SCIENCE! aaaaand my physics text book

Option B is correct:  The food coloring in the hot water will spread more quickly than in the cold water because water molecules move more quickly when hot since they have more kinetic energy.

Kinetic energy of the molecules:

According to the question, we place a drop of blue food coloring in a cup of cold water and another drop of food coloring in a cup of hot water and then observe the spreading of the blue color in both the cups.

Option B will be correct because the kinetic energy of the molecules of a gas or a liquid is directly proportional to the absolute temperature of the gas or the liquid.

High kinetic energy means that the molecules will have higher velocity, which will make it easier for any solvent to dissolve in water since it will spread faster.  

So the cup which has water at a higher temperature will have a faster spread of the food coloring.
