Answer:
acceleration = final velocity - initial velocity / time
V-U/T
Explanation:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
Answer:
5.38035 m
Explanation:
= Refactive index of water = 1.43
h = Depth = 5.5 m
Critical angle is given by
d = horizontal distance from the post where she no longer see the bottom of wooden post
So,
The distance d is 5.38035 m
The first part is pretty straight forward, vₓ=v₀+a(t). Convert final velocity to m/s to get 97.2m/s. v₀=0, a=4. Solving for t yields 24.3 seconds.
For the second part use "vₓ^2(final velocity) = v₀^2(initial velocity) + 2a(Δx). Final velocity is 97.2m/s, initial velocity is 0, acceleration is 4m/s^2. Solving for Δx yields 1181.53 meters.
<span>Presuming that the gas behaves like an ideal gas:
Volume in cubic meter V= 59.6x 0.001= 0.0596 mÂł
n=3.01 mol
Temperature in Kelvin T=44.9+273.15=318.05 K
R= 8.413 J/ mol K
The ideal gas law:
PxV= nxRxT
Substituting the give information from the question into the ideal gas law:
P= 3.01 mol x 8.413 J/mol k x 318.05 K / 0.0596= 133544.392 Pa
1351.3458 Pa / 101325 Pa/ atm = 1.3179806 atm</span>
Answer:
Explanation:
Given that,
Initial speed, u = 5 m/s
Final speed, v = 10 m/s
Time, t = 2 s
The radius of the tire of the bike, r = 35 cm
We need to find the angular acceleration of the pebble during those two seconds. It can be calculated as follows.
So, the required angular acceleration of the pebble is equal to .
