If predators a and b prey upon the same species and predator a is eliminated

I would think Predator B would get more food from the species since Predator A was Eliminated.

For Example: if two dogs want the same bowl of food, they are going to fight or try and beat one another to it. So if Predator A is gone then Predator B has the species all to himself unsless another Predator comes.

Hope this helped!!

Earthquakes and volcanic eruptions are examples of rapid events that are caused by the movement of Earth's _______. Mountain bui

andrew11 [14]

The correct answer is - C. Crustal plates, crustal plates.

The movement of the crustal plates of the Earth is the reason why the geologic processes are occurring on our planet. With their movement, the crustal plates manage to create lot of pressure, open up gaps for the magma from the mantle, as well as make adjustments deeper into the ground.

Because of the adjustments deep into the ground, or rather the crust, lot of force is released, manifested as strong and very quick vibrations, better known as earthquakes.

The gaps that are opening between the plates let the magma reach the surface, thus enabling the volcanic activities on the planet.

The pressure from the plates' collision makes the land lift up slowly, and over time a mountain range starts to form because of the continuous lifting up of the area.

DENIUS [597]

The function of the crankshaft is to convert the up-and-dwon motion of the piston into rotary motion that can be used to power the vehicle.

I attache an image of a crankshaft.

The pistons are connected to the crank pins ans when the pistons move up an down the crankshaft rotate, and so the recoprating movement of the pistons is converted into rotary motion.

1) What is the power in horsepower of a 100 watt light bulb? What is the power in kilowatts of a 200 horsepower engine?

Yuki888 [10]

1). Use the definition 1 Horsepower = 746 watts

100 watts = (100/746) HP = 0.134 Horsepower

2). Use the definition Power = (work done) / (time to do the work)

and the definition Work = (force) x (distance moved)

(3,000 N x 5 m) / second

= (3,000 x 5 N-m) / second

= (15,000 joules) / second

= 15,000 watts

3). Use the definition Power = (work done) / (time to do the work) , and the definition Work = (force) x (distance moved) , and the 'customary' definition of 1 Horsepower = 550 foot-pounds per second.

Let the answer ... the number of gallons ... be called ' G ' until we know what it actually is.

Weight of water lifted in 1 minute = (G gallons) x (8.34 pounds/gallon)

The distance it's lifted = 30 feet

Work done in 1 minute = (force x distance) = (8.34G x 30) foot-pounds

In just a moment, we're going to need this in seconds:

Power = (8.34G x 30 foot-pounds/minute) x (1 minute / 60 seconds)

Power = (8.34G x 30/60) (foot-pound-minute/minute-sec)

Power = 4.17G foot-pound/sec

The power = 1/2 Horsepower = 225 foot-pounds / sec

So finally, 225 = 4.17G

Divide each side by 4.17, and we have

G = (225/4.17) gallons

G = 53.96 gallons

I really should check this over, but I've had it up to here with gallons, feet, horsepower, and pounds, so I'm not gonna do it. Read my lips. It is what it is. I stand or fall by my answer. What could go wrong ? !

Physics what is the aim of this experiment

Ainat [17]

Answer:

An experiment usually tests a hypothesis, which is an expectation about how a particular process or phenomenon works. However, an experiment may also aim to answer a "what-if" question, without a specific expectation about what the experiment reveals, or to confirm prior results.
