What is relative velocity?​

Answers

Relative velocity is the velocity of an object or observer B in the rest frame of another object or observer A

Answer:

the velocity of a moving body relative to another body is called relative velocity.

A fan uses 7A when connected to a 110V line. If electric power costs 10 cents per kilowatt-hour in this location, what is the cost of running the fan for 13 hours?

Answers

Power = current x voltage

So the power is 7 x 110 = 770 W = 0.77kW

0.77 x 13 = 10.01 kWh

10.01 x 10 cents = 100.1 cents (is this 1 dollar? Idk I use a different currency)

You and a friend ride bicycles to school. Both of you start at the same instant from your house, you riding at 13 m/s and your friend riding at 18 m/s . During the trip your friend has a flat tire that takes him 13 min to fix. He then continues the trip at the same speed of 18 m/s . If the distance to school is 13 km , which of you gets to school first? By comparing the total journey time for you and your friend, this question can be answered.

Answers

V1 = 13 m/s
V2 = 18 m/s
L = 13 km = 13000 m
t0 = 13 min = 780 s

t1 = L/V1 = 13000/13 = 1000 seconds = 16.67 min
t2 = t0 + L/V2 = 780 + 13000/18 = 1500 s = 25 min
You will get to school first

State 2 applications of convection in daily life​

Answers

Final answer:

Convection is a process that helps distribute heat, notably in daily applications such as heating systems and cooking. It involves the movement of heat through fluids, where hotter parts become less dense and rise, creating a current.

Explanation:

Convection is a significant process in our daily lives that enables the transfer of heat in fluids (liquids and gases) from one place to another.  

One common application of convection is seen in Heating Systems. For instance, in a radiator, hot water or steam travels through the system, heats the surrounding air, and this hot air rises, creating a convection current that distributes the warmth throughout a room.

Another prime example of convection at work is Cooking. When you boil water or cook in a pot, the heat from the stove heats up the pot which then heats the water at the bottom. This hot water rises, pushing the cooler water to the bottom where it too gets heated, thus creating a convection current.

A boat sails along the shore. To an observer, the boat appears to move at a speed of 11 m/s, and a man on the boat walking forward appears to have a speed of 12.4 m/s. How long does it take the man to move 6 m relative to the boat?

Answers

You first subtract the speed at which the man is moving (11 m/s) from the rate the boat is moving (12.4 m/s). Which equals 1.4, then divide it by 6 meters, as the man is moving relative to the boat.

It therefore equals 4.29 s

Answer:

4.29 s

The planet and its moon gravitationally attract each other. Rank the force of attraction between each pair from greatest to least.

Answers

The greatest to the least would be:

  • 2m-D-m
  • M-D-2m
  • M=D=M
  • M=2D=2M

What is meant by force of attraction

The force of attraction refers to the physical phenomenon in which objects are drawn toward each other due to gravitational, electromagnetic, or other fundamental forces. This attraction can be explained by several different interactions, including:

Gravitational Attraction: This is the force of attraction between two objects with mass. According to Newton's law of universal gravitation, every mass in the universe attracts every other mass with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

#SPJ3
The gravitational force between two attracting objects can be solved through the equation,
                               F = Gm₁m₂ / d²
where m₁ and m₂ are there masses, d is the distance, and G is the gravitational constant. These means that the force is directly related to the masses and inversely to the distance. From the given choices, B will have the greatest energy, followed by C and A, respectively. Lastly, the least force will that be of D.
