Relax. You're not completely lost.
The car has to cover 600 km. That's 600,000 meters.
If it could only move at 1 meter per second, it would take the car 600,000 seconds to cover the distance. (almost a week !)
But it can move faster than that. In fact, it can cover 80 meters every second.
How many times does it need to do 80 meters, in order to cover the whole 600,000 ? That's how many seconds it'll take.
That's division.
Answer:
so height is 0.1283 m
Explanation:
given data
height = 28 cm
diameter = 11 cm
cross-sectional area = 1.55 cm2
water flow rate = 2.46×10^−4 m3/s
to find out
How high will the water in the bucket rise
solution
we know that here
potential energy = kinetic energy
mgh = 1/2 mv²
multiply both sides by the 2 and we get
2mgh=mv²
solve it we get
√(2gh) = v ....................1
h = v²/2g ...............2
and
flow rate = A V
2.46×10^−4 = V 1.55×10^−4
V = 1.5870 m/s
so from 2
h = v²/2g
h = 1.5870²/ 2(9.81)
h = 0.1283 m
so height is 0.1283 m
Water can dissolve salt<span> because the positive part of water molecules attracts the negative </span>chloride<span> ions and the negative part of water molecules attracts the positive </span>sodium<span> ions. The amount of a substance that </span>can dissolve<span> in a liquid (at a particular temperature) is called the </span>solubility<span> of the substance.</span>
Impact theory is the idea that the moon was formed by a collision between the Earth and another body.
The capture theory is the idea that the moon formed somewhere else in the solar system. The theory proposed that the moon was just an asteroid pulled into orbit by the Earth.
Co-formation is a theory that proposes that the Earth and the moon formed around the same time as each other from a primitive solar nebulae.
The answer to your question then is CAPTURE THEORY.
Answer:
Explanation:
Here at thermal equilibrium we can say that thermal energy given by Hot coffee is equal to the thermal energy absorbed by ice cubes
So here we have
now since ice cubes are added into coffee when it is at melting temperature
So here we can say that final temperature of coffee is T degree C
Now we have
here we have
L = 333 kJ/kg = 333 J/g[/tex]
now we have
