Although the speeds are different, but the two waves will
reach the same station so the same distance.
dp = ds
The formula for distance given velocity and time is:
d = v t
Substituting this to the 1st equation:
vp tp = vs ts
Since p wave arrived 2 min (120 s) earlier than s wave,
therefore
tp = ts - 120
Then,
vp (ts – 120) = vs ts
8.5 (ts – 120) = 5.5 ts
8.5 ts - 1020 = 5.5 ts
3 ts = 1020
ts = 340 s
tp = ts – 120 = 340 – 120 = 220 s
Then using either dp or ds, we can calculate how far away the
earthquake is:
dp = vp tp
dp = 8.5 * 220
dp = 1870 km = 1.9 * 10^3 km
Answer:
0.
Explanation:
(A) Work done on the dresser which will be given as :
where, F = weight of the dresser = 3500 N
However you can move the dresser, that is a real distance,
Substituting,
(
is the angle at which you apply the force)
Answer:
Explanation:
I dont know if this will help but A two force member is a body that has forces (and only forces, no moments) acting on it in only two locations. In order to have a two force member in static equilibrium, the net force at each location must be equal, opposite, and collinear.
Climate change is the reason for a lot of factors such as:
Heat-trapping Greenhouse Gases And The Earth's Climate
Greenhouse Gases
Reflectivity or Absorption of the Sun's Energy
Changes in the Earth's Orbit and Rotation
Variations in Solar Activity
Changes in the Earth's Reflectivity
Volcanic Activity
There's a lot more that I could list, but hopefully this will do.
A sound wave is a longitudinal wave
