Answer:
0.4 km/h
Explanation:
Speed is defined as distance moved per unit time and can be expressed in either m/s or Km/h or miles/h
Mathematically,
where d represent distance covered and t is time taken
Taking d as 100 m and converting it into km, we divide by 1000 hence d= 0.1 km
Time is 15 minutes and to convert to hours we divide by 60 hence 0.25 hours
Speed,
Therefore, the speed is equivalent to 0.4 km/h
Not going to type it all for you but possible weight difference has a major roll in answering this
Answer:
They are <em>directly proportional</em> to gravitational force.
Explanation:
Newton's Law of Gravity states that . The two "m" values are the masses of the objects, <em>r</em> is the distance between their centers, and G is the gravitational constant. Notice how the "m" values are in the fraction's numerator (i.e., on top)? That means <em>increasing</em> even one of the objects' masses will <em>increase</em> the gravitational force. This is known as a <em>direct relationship</em>.
Of course, you could always use the wonderful table provided to solve this! You don't believe what I wrote above? Take on of the two objects' masses, divide the gravitational force by that number, and see what happens. Multiply the two masses together, and see what happens. Prove it for yourself!
I hope this increases your understanding of this concept. Have yourself a wondrous day, 'kay?
The statements which best describe the properties of tsunami waves are these: 1. THEY HAVE LONG WAVELENGTH.
2. THEY TRAVEL AT VERY HIGH SPEED.
Tsunami typically occur as a result of sudden displacement of gigantic water masses which erupted due to earthquake that occur on the sea bed. One peculiar characteristic of tsunami is the very wide distances between its wavelengths. A tsunami is a very long wavelength waves of water, its wavelength is much more greater than that of ordinary wave and can be as much as 300 kilometer.
Wavelength is refers to the distance between two identical points on a wave, that is, between wave crests or wave troughs.
Tsunami also travels at very high speed; it can travel for a long period of time at high speed without losing much energy.
