I think the correct answer from the choices listed above is the second option. The relationship between the direction of energy and wave motion in a transverse wave would be the <span>energy direction is perpendicular to the motion of the wave. Hope this answers the question. Have a nice day.</span>
Answer:
Explanation:
d = v * t, where d is the distance and v is the velocity, t is the time
cheetah
v = 95.4 km/h
gazelle
v= 74.4 km/h
d1 = 83m = 0.083 km
when the cheetah catches the gazelle the distances will be equal
95.4t= 74.4t+0.083
t= 0.00395 h* (3600s/1h) = 14.22 s
Answer:
D = 7.82 m
Explanation:
given,
speed of horse = 10 m/s
vertical distance between the saddle and limb = 3 m
horizontal distance = ?
Calculation of time taken to cover the vertical distance.
using equation of motion
initial velocity = 0 m/s
![t = \sqrt{\dfrac{2s}{a}}](https://tex.z-dn.net/?f=%20t%20%3D%20%5Csqrt%7B%5Cdfrac%7B2s%7D%7Ba%7D%7D)
![t = \sqrt{\dfrac{2\times 3}{9.8}}](https://tex.z-dn.net/?f=%20t%20%3D%20%5Csqrt%7B%5Cdfrac%7B2%5Ctimes%203%7D%7B9.8%7D%7D)
t = 0.782 m
horizontal distance covered in this time
D = v t
D = 10 x 0.782
D = 7.82 m
Horizontal distance covered is equal to 7.82 m.
The correct answer is false i just took the test
Atomic number is the same number as the amount of protons. Atomic mass is the sum of protons and neutrons: the two sub-atomic particles only found in the atomic nucleus. Number of neutrons is equal to atomic mass (z) - atomic number (n), so 27-13=14 neutrons
