Answer:

The maximum possible up-thrust on the boat is 11,995.2 N

Explanation:

According to Archimedes' principle, the thrust received by an object immersed a fluid is equal to the weight of the fluid displaced;

The given parameter of the boat in sea water are;

The volume of the boat = 1.2 m³

The density of seawater = 1020 kg/m³

Density = Mass/Volume

Therefore, Mass = Density × Volume

The maximum volume of water that the boat displaces = 1.2 m³

The mass of the water displaced by the boat = (Density of seawater) × (Volume of seawater displaced)

∴ The maximum possible mass of the water displaced by the boat = 1.2 m³ × 1020 kg/m³ = 1224 kg

The maximum possible mass of the water displaced by the boat, m = 1224 kg

Weight = Mass, m × g

Where;

g = The acceleration due to gravity = 9.8 m/s²

The up-thrust on the boat = The weight of the seawater displaced

∴ The maximum possible up-thrust on the boat = m × g = 1224 kg × 9.8 m/s² = 11,995.2 N

The maximum possible up-thrust on the boat = 11,995.2 N.

You walk forward at 1.5 m/s for 8s. Your friend decides to walk faster and starts out at 2.0 m/s for the first 4 s. Then she slo
Troyanec [42]
The first thing you should know is that the distance is equal to the speed per time.
 Therefore if You walk forward at 1.5 m / s for 8s
 d = 1.5t [0,8] s
 Your friend decides to walk faster and starts at 2.0 m / s for the first 4 s.
 d = 2t [0,4] s
 Then she slows down and walks forward at 1.0 m / s for the next 4s
 d = t + 4 [4,8] s
 Who walked farther?
 They both walked the same distance
 12 meters

g A wheel of diameter 8.0 cm has a cord of length 6.0 m wound around its periphery. Starting from rest, the wheel is given a con
sveticcg [70]

To solve this problem it is necessary to apply the equations related to the description of the tangential and angular movement.

The displacement where the speed and acceleration is related is given by the equation:

x = v_0t+\frac{1}{2}at^2

Where

v_0 = Initial velocity (0 because start from rest)

t = time

a = Acceleration

We have angular acceleration but not tangential acceleration. Tangential acceleration can be obtained through the relationship

a = r\alpha \rightarrow r = \frac{diameter}{2}

a = \frac{0.08}{2}(3)

a = 0.12m/s^2

And we have also that the displacement is

x = 6m

Now replacing,

x = v_0t+\frac{1}{2}at^2

6 = 0*t+\frac{1}{2}(0.12)t^2

6 = \frac{1}{2}(0.12)t^2

t = 10s

Therefore will take the cord to unwind around 10s
