Answer:

The absolute pressure of air inside the tank is 164.7 psi.

Explanation:

Given that,

Atmospheric pressure = 14.7 Psi

Gauge pressure = 150 psi

We need to calculate the absolute pressure of air inside the tank

Using formula of absolute pressure

P_{ab}=P_{g}+P_{atm}

Where, P_{g} = gauge pressure

P_{atm} =atmospheric pressure

Put the value into the formula

P_{ab}=150+14.7

P_{ab}=164.7\ psi

Hence, The absolute pressure of air inside the tank is 164.7 psi.

If the mass of the ladder is 12.0 kgkg, the mass of the painter is 55.0 kgkg, and the ladder begins to slip at its base when her
Marysya12 [62]

Answer:

 μ = 0.336

Explanation:

We will work on this exercise with the expressions of transactional and rotational equilibrium.

Let's start with rotational balance, for this we set a reference system at the top of the ladder, where it touches the wall and we will assign as positive the anti-clockwise direction of rotation

          fr L sin θ - W L / 2 cos θ - W_painter 0.3 L cos θ  = 0

          fr sin θ  - cos θ  (W / 2 + 0,3 W_painter) = 0

          fr = cotan θ  (W / 2 + 0,3 W_painter)

Now let's write the equilibrium translation equation

     

X axis

        F1 - fr = 0

        F1 = fr

the friction force has the expression

       fr = μ N

Y Axis

       N - W - W_painter = 0

       N = W + W_painter

       

we substitute

      fr = μ (W + W_painter)

we substitute in the endowment equilibrium equation

     μ (W + W_painter) = cotan θ  (W / 2 + 0,3 W_painter)

      μ = cotan θ (W / 2 + 0,3 W_painter) / (W + W_painter)

we substitute the values ​​they give

      μ = cotan θ  (12/2 + 0.3 55) / (12 + 55)

      μ = cotan θ  (22.5 / 67)

      μ = cotan tea (0.336)

To finish the problem, we must indicate the angle of the staircase or catcher data to find the angle, if we assume that the angle is tea = 45

       cotan 45 = 1 / tan 45 = 1

the result is

    μ = 0.336

A boat has a mass of 6800 kg. its engines generate a drive force of 4100 n, due west, while the wind exerts a force of 830 n, du
erastova [34]

 Let positive be west and negative be east because they are contrasting in directions.

 
The forces are 4100, -830, and -1200

 
The sum of the forces is 4100 – 830 – 1200 = 2070 N. 

Newton’s law F = ma is used. 
2070 = 6800 a 

Isolating a will give us 2070 / 6800 = a

a = 0.34 m/s^2

A placekicker kicks a football upward at an angle of 30 and a speed of 5.0 m/s at what other angle will he have to kick a second
Flura [38]

Answer:60^{\circ}

Explanation:

Given

speed of ball u=5 m/s

launch angle \theta =30^{\circ}

Range of a Projectile R=\frac{u^2\sin 2\theta }{g}

Range will be common for two angles i.e. \theta [tex] and [tex]90-\theta

for \theta R=\frac{5^2\sin 2\cdot 30}{g}

R=2.209 m

For 90-\theta

90-30=60^{\circ}

R=\frac{5^2\sin 2\cdot 60}{g}

R=2.209 m
