Answer:

The bulb consumes electrical energy at the rate of 500 Watts

1 Watt = 1 Joule/sec  where the joule is the unit of energy

Electric energy is often expressed in kw-hrs

This means that 1 kilowatt of power is used for 1 hour

1 kw-hr = 1000 joules/sec * 3600 sec = 3.6E6 joules of energy

Answer:

The depth of water near middle tube is greater so the water comes out with greater pressure from middle tube and falls farther away from the base of vessel. The depth of water near lowermost tube is the greatest so the water comes out of lowermost tube with the greatest pressure and goes farthest from the vessel.

Answer:

This is Newton's second law.

Newton's second law text:

(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)

F=ma

net force = mass x acceleration

Answer:

A. 25 m/s2

hope it's right

If a  car accelerates from 7.0 m/s to 12.0 m/s in 5 s, then the average acceleration for this time interval would be 1 m/s2.

Therefore the correct answer is option C.

The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter/seconds².

As given in the problem If a  car accelerates from 7.0 m/s to 12.0 m/s in 5 s, then w have to calculate the average acceleration for this time interval,

By using the first equation of motion,

v = u +at

12 = 7 + 5a

5a = 5

a = 1 m/s²

Thus, the average acceleration of the car comes out to be 1 m/s², therefore the correct answer is option C.

Answer: One example of an experiment you can do is find out the heat difference between a white car and a black car using the sun in a hot day.

Explanation: The black car would absorb more heat from the sun and would make the inside of the black car hotter than the white car.

explanation:

Here,

Using Formula;

v = u + at

or, 7 = 0 + (6.6*t)

or, 7 = 6.6t

or 7/6.6 = t

or, t = 1.06s

Answer:

30 m/s

Explanation:

0^2= Vi^2+ 2 (-45)(10)

The original speed of the car is equal to 30m/s which can be calculated from the third equation of motion.

Equations of motion explain the basic concept of motion such as the position, velocity, or acceleration of an object several times. These three equations of motion can be governed by the motion of an object in 1D, 2D, and 3D.

There are three equations of motion that can be used to find displacement(s), velocity (v or u), time(t), and acceleration(a). The third equation of motion can be represented as follows:

v² = u² + 2aS

Given, the car is deaccelerated by 45m/s².

The distance covered by the car before it stops, S = 10 m

The final velocity of the car, v = 0 as it comes to rest.

We have to calculate the initial velocity of the car by using the third equation of motion:

(0)² = (u)² + 2 (-45) × (10)

u²= 900

u = 30 m/s

Therefore, the original speed of the car is 30 m/s.

Science is a way of learning about what is in the natural world, how the natural world works, and how the natural world got to be the way it is. It is not simply a collection of facts; rather it is a path to understanding.so it should contain a logical theory but it can also never be said as the final answer.

Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per

second. Answer B is wrong because velocity increases. Answer C is wrong because the

distance increases every second. Ans. E is wrong because the derivative of distance with

respect to time gives the velocity, not the acceleration.

The density of an object remains same irrespective of its shape, size and quantity.

Explanation:

Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. It is because density in an intensive property of matter.

It then pauses before flying with an average velocity of 6.8 m/s east for 3.5 s to another branch.

Answer:

9 m/s

Explanation:

The seagull flew at a constant velocity for a total of 32 seconds.

One-quarter of 32 is:

[tex]\implies \dfrac{1}{4} \times 32=\dfrac{32}{4}=8\; \sf seconds[/tex]

Therefore, if the seagull flew 72 meters in one-quarter of 32 seconds, it flew 72 meters in 8 seconds.

[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

To find the velocity (speed) of the seagull, substitute the distance and time into the formula:

[tex]\implies \sf Velocity=\dfrac{72}{8}=9\; \sf m/s[/tex]

the lionfish, a longstanding showstopper in home aquariums, is a flourishing invasive species in U.S. Southeast and Caribbean coastal waters. This invasive species has the potential to harm reef ecosystems because it is a top predator that competes for food and space with overfished native stocks such as snapper and grouper. Scientists fear that lionfish will also kill off helpful species such as algae-eating parrotfish, allowing seaweed to overtake the reefs. In the U.S., the lionfish population is continuing to grow and increase its range. This is largely because lionfish have no known predators and reproduce all year long; a mature female releases roughly two million eggs a year.
