While the Orion constellation is named after the hunter in Greek mythology, it is anything but stealthy. Orion, which is located on the celestial equator , is one of the most prominent and recognizable constellations in the sky and can be seen throughout the world.
Answer: B 2V
Explanation:
Since the voltage of the battery is 2V.
At point A and B, there is no voltage drop. So the voltage will still be same as in the battery which is 2V.
Answer:
114.19186 m
Explanation:
v = Velocity of girl at bottom = 7.1 m/s
= Coefficient of kinetic friction = 0.045
g = Acceleration due to gravity = 9.81 m/s²
d = Distance
N = Normal force = 783 N
The weight of the sled and girl is considered as the sum of the frictional force and weight
Hence we use the following equation where the kinetic energy and potential energy are conserved
The sled travels 114.19186 m on the level ground before coming to a rest
Given parameters:
Volume of water in the tank = 750litres
Length of the tank = 150cm
Breadth of tank = 50cm
Unknown:
Height of the tank = ?
To solve this problem, we must understand the concept of volume. Volume is a property of solid bodies. It is mathematically derived as:
Volume = length x Breadth x height
The unknown here is the height and we should go ahead to solve for it.
<em>But the units are inconsistent. </em>
Therefore, convert litres to cm³;
1 litre = 1000cm³
750 litres = 1000 x 750 = 750,000cm³
Now input the parameters and solve for the height;
750000 = 150 x 50 x height
height = = 100cm
Therefore, the height of the tank is 100cm
Some characteristics I think would include that low energy waves have a greater distance between the points on the crest or points on trough in the wave. Greater, longer wavelength. Thus lower frequency hence less energy provided through the wave. The amplitude for low energy waves is less than that of high energy waves. Basically the height of the wave.
