Answer:
x = 1382.9 km
Explanation:
The speed of the wave is constant, so we can use the uniform motion relationships
p wave
= x / t₁
t₁ = x /v_p
S wave
v_s = x / t₂
t₂ = x / v_s
indicate that the time difference between the two waves is
t₂ - t₁ = 3.25 min (60 s / 1 min)
t₂ -t₁ = 195 s
let's substitute
= 195
x ( = 195
let's calculate
x = 195
x (0.1410) = 195
x = 195 /0.141
x = 1382.9 km
Answer:
0.73m/s2
Explanation:
The speed at which the passengers move is the final speed of the plane
Hence acceleration = V-U/t; change in velocity and t is time taken. U is the initial velocity which is 0m/s
a = 73-0/100= 0.73m/s2
Answer:
The average velocity of the ball is 1.355 cm/s.
Explanation:
Given;
initial displacement of the ball, x₁ = 8.4 cm
final displacement of the ball, x₂ = 4.2 cm
initial time, t₁ = 3.0 s
final time, t₂ = 6.1 s
The average velocity of the ball is calculated as;
Therefore, the average velocity of the ball is 1.355 cm/s.
Answer:
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. Renewable resources are replenished naturally and over relatively short periods of time. The five major renewable energy resources are solar, wind, water (hydro), biomass, and geothermal.
