3. Our favorite nature explorer Steve Irwin is currenty warking with crocodiles in the Nile River. One of the big boy crocs gets

hungry and takes off after some prey. Steve and his wife Terri want to know how much kinetic energy the croc exhibits when chasing prey. The croc has a mass of 600 kg and can swim at a velocity of 4 m/s. Calculate the kinetic energy of the croc,​

Answer:

K.E = 4800 Joules.

Explanation:

Given the following data;

Mass = 600 kg

Velocity = 4 m/s

To find the kinetic energy;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have;

K.E = \frac{1}{2}*600*4^{2}

K.E = 300 * 16

K.E = 4800 Joules.

A speed truck locks it’s brakes and it skids to a stop. If the truck’s total mass were doubled, it’s skidding distance would be?
Gnom [1K]

Answer:

The skidding distance would be doubled

Explanation:

When the truck applies the brakes and slows down, its motion is a uniformly accelerated motion, so its skidding distance can be found by using the suvat equation

v^2-u^2=2as

where

v = 0 is the final velocity (zero since the truck comes to a stop)

u is the initial velocity

a is the acceleration

s is the skidding distance

The acceleration can also be written as

a=\frac{F}{m}

where F is the force applied by the brakes and m the mass of the truck. Substituting into the previous equation,

-u^2 = 2\frac{F}{m}s\\s = -\frac{mu^2}{2F}

We see that the skidding distance is proportional to the mass: therefore, if the mass of the truck is doubled, the skidding distance will double as well.

-What is the storm on Saturn called?
Harrizon [31]

Answer:

-the Great White Spot

-At least, you wouldn't be able to live on Saturn like you'd live on Earth, or perhaps even Mars. Saturn is what we call a “gas giant.” It is a planet made up most of hydrogen and helium. This means that there is no solid surface on Saturn, Well, that we know of, anyway. ... Saturn doesn't have any of that.

-Enceladus orbits the planet at a distance of about four Saturn radii, replenishing the torus with its jets of water. ... Saturn's atmosphere is known to contain traces of gaseous water in its deeper layers. A particular enigma has been the presence of water in its upper atmosphere.

-On the planet of the rings the atmosphere holds a treasure: real showers made from diamonds. What makes precious stones rain down on this planet? On Saturn, the combination of methane with storms produces a shower of diamonds. ... About 10 million tons of diamond rain down on Saturn each year

-A unique feature of Saturn is that it is the least dense planet in the Solar System. Although Saturn may have a dense, solid core, the large gaseous outer layer of the planet makes its average density a mere 687 kg/m3. As result, Saturn is lighter than water.

-Viewed from Earth, Saturn has an overall hazy yellow-brown appearance. The surface that is seen through telescopes and in spacecraft images is actually a complex of cloud layers decorated by many small-scale features, such as red, brown, and white spots, bands, eddies, and vortices, that vary over a fairly short time.

-hexagon

-58,232 km

-0d 10h 42m

-Saturn's hexagon is a persistent approximately hexagonal cloud pattern around the north pole of the planet Saturn, located at about 78°N.

-Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly.

-Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. ... Dark Energy makes up 72% of the total mass-energy density of the universe. The other dominant contributor is Dark Matter, and a small amount is due to atoms or baryonic matter.

-It's possible that before the Big Bang, the universe was an infinite stretch of an ultrahot, dense material, persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale, Carroll said
