Answer:
v = 4t - t²/3
Explanation:
4 - k*6 = 0
k = 4/6 = 2/3
dv/dt = 4- 2/3 t
integral of dv = integral of (4-2/3 t) dt
v = 4t - t²/3
Answer:
the beetle's actual distance beneath the surface, d = 3.2 cm
Explanation:
The refractive index for the plastic is about 1.60
For overhead viewing, the expression for refractive index is
n = actual depth / apparent depth
Rearrange for actual depth
actual depth d = n x apparent depth
d = 1.60 x 2.0 cm
d = 3.2 cm
Answer:
Explanation:
From the question we are told that:
coefficient of static friction
Velocity
Generally the equation for Conservation of energy is mathematically given by
Absolute pressure at the bottom of the lake = pressure due to water height + Air pressure = Density of water*gravitational acceleration* height + 101.3 kPa
Therefore,
Absolute pressure = 1/1000(1*10^3*9.81*29.1) + 101.3 = 285.471+101.3 = 386.771 kPa
