Answer:
8.44 m/s.
Explanation:
Change in Potential Energy = Mass x Acceleration From Gravity x H2 - H1
Kinetic Energy = 1/2 (mass) x [(v2)^2 - v1^2]
g * h = 1/2 * v^2
(9.8) x (2.27) = 1/2 * (v)^2
v^2 = 2[(9.8) x (2.27)]
v = 6.67 m/s
g * delta h = 1/2 * delta v^2
(9.8) x (2.27 - 0.903) = 1/2 * [(v2)^2 - (6.67)^2]
v2^2 = 71.2821
v2 = 8.44 m/s
ANSWER :
(A) AT RIGHT ANGLES TO THE DIRECTION THE WAVE TRAVELS.
EXPLANATION :
TRANSVERSE WAVES IS THAT IN WHICH THE PARTICLES VIBRATE WITH AN UP-AND-DOWN MOTION. THE PARTICLES IN A TRANSVERSE WAVE MOVE ACROSS OR PERPENDICULAR TO THE DIRECTION THAT THE WAVE IS TRAVELING OR AT RIGHT ANGLES TO THE DIRECTION THE WAVE TRAVELS.
False, because if you take too much calories, you are have too much. That means you are in the positive, you have too much energy.
and if you take fewer, you will have less calories, so less energy.
Answer:
a. water
Explanation:
A buoy is a floating object that is used in the sea to locate some point or as a checkpoint. It stays at its designated position in the sea by means of an anchor chain. This chain is made short in length according to the water depth do the buoy can not deviate much from its position. The same mechanism can be applied to the metal ion. When a metal ion is formed it remains at its place, but the electrons are mobile and they travel when they get a medium. For example in circuits or from one atom to other. And for the case of buoy, the water serves as electrons as the water is moving in the medium. Hence, the second analogy will be:
electrons : water
So, the correct option is:
<u>a. water</u>
