A. Molecular solids tend to have lower melting points than Ionic so it would be Ionic if it weren't for Molecular.
Therefore the world's record high temperature of 134.0°F (56.7°C) is held by Furnace Creek Ranch in Death Valley, California. That global high temperature was attained on July 10, 1913.
Answer:
<h3>30m</h3>
Explanation:
Velocity is the change of rate of displacement with respect to time.
velocity = displacement/time
Given
initial velocity = 15 m/s.
time taken =2 secs
Required
Displacement of the object
From the formula;
Displacement = Velocity * time
Displacement = 15 * 2
Displacement = 30m
<em>Hence the displacement of the object is 30m</em>
Answer:
The time taken will be 0.553 seconds.
Explanation:
We should start off by finding the force exerted by the rope on the 3kg weight in this case.
Weight of 5kg mass = 5 * 9.81 = 49.05 N
Weight of 3kg mass = 3 * 9.81 = 29.43 N
The force acting upward on the 3kg mass will equal the weight of the 5kg mass. Thus the resultant force acting on the 3kg mass is:
Total force = 49.05 - 29.43 = 19.62 N (upwards)
We can now find the acceleration:
F = m * a
19.62 = 3 * a
a = 6.54 m/s^2
We now use the following equation of motion to get the time taken to travel 1 meter:
t = 0.553 seconds
Answer:
solid, liquid, gas
Explanation:
The three phases of water are the three states of matter water can be found in, and that is:
solid (as in ice)
liquid (as in water)
gas (as in water vapor)
